Acura RDX Wheel Bolt Pattern, Rim Size, Hub Bore And Offsets

Introduction

On the road, the Acura RDX has developed a strong reputation as one of the most dependable and fashionable small luxury SUVs available. Whether you're riding in the newest generation or sporting a first-generation vehicle, you most likely know that wheels affect driving dynamics, safety, and even fuel economy, not only appearance. Finding the right wheel fitment for your RDX isn't always easy, though, with so many model years, trim cuts, and options.

We are delving deeply in the wheel fitting specifics for every Acura RDX generation from 2007 all the way forward in this guide. Everything you need to know before you start shopping for aftermarket wheels or even OEM replacements—the basic specs like bolt patterns, hub bores, offsets, rim widths, and suggested tire sizes will be broken out here.

Over its three years, the Acura RDX has seen several notable alterations. Acura has adjusted suspension systems, drivetrain choices, and wheel sizing needs from the sporty and small first generation to the more refined and tech-heavy current models. This instruction is worth your attention since what worked flawlessly on an RDX in 2008 could not suit a 2019 model without some trouble.

Getting the correct wheel fitment is vital whether your goals are more aggressive stance, better ride, or simply replacement of worn-out wheels. It influences comfort, handling, braking, and RDX appearance in addition to other things. We will ensure you get a complete breakdown for every generation in the next sections without excluding the little but crucial elements.

Acura RDX Generations Overview

Since its introduction back in 2007, the Acura RDX has been rather popular in the premium SUV market. Acura has changed its design, technology, most crucially its wheel and tire configuration, significantly throughout the years. Before going into precise wheel fitment specifics, one must first understand the generational shifts.

Acura RDX was Acura's first effort at a small luxury SUV, and in terms of sporty handling and performance, they nailed it. 2007–2012 It came standard with Acura's Super Handling All-Wheel Drive (SH-AWD) matched with a turbocharged inline-4 engine. This version employed a smaller, performance-oriented wheel configuration. Wheel diameters ranged from 18x7.5 inches; bolt pattern was 5x114.3; hub bore measured 64.1mm; offsets usually amounted to +50mm. This balanced the RDX while preserving strong steering response.

The second generation, 2013–2018, tended more toward luxury and comfort. Acura changed the suspension for a better ride and dropped the turbocharged engine with a naturally aspirated V6. The wheels increased significantly along with this shift. Depending on trim levels, factory rim sizes went from 18x7.5 to 19x8 inches. Bolt pattern kept 5x114.3; hub bore stayed at 64.1mm; offsets were changed between +45mm and +55mm. Acura improved ride quality by playing it safe with fitting, without compromising much performance.

Things were elevated by the third generation (2019–present). Acura changed the chassis, brought back a turbocharged 2.0L engine, and changed wheel choices mostly. Factory wheels today span 19x8 to 20x8.5 inches. Acura somewhat expanded the hub bore to 64.1mm, maintaining consistency with previous models, but the bolt pattern remains 5x114.3. Depending on the wheel size and trim, offsets today fall from +45mm to +55mm. This generation is far friendlier to more modestly modified larger aftermarket wheels.

Whether you maintain your RDX standard or are looking for a fresh aftermarket look, knowing these variations will enable you to match the appropriate wheels.

1st Generation Acura RDX (2007 - 2012) Wheel Fitment

For its class, the first-generation Acura RDX arrived swinging with a turbocharged engine and strong driving dynamics. Acura gave it a performance-ready wheel arrangement straight from the factory due to its sportier character.

All versions included 18-inch wheels; the OEM specification is 18x7.5J, along with 235/55R18 tires. With a 5x114.3 bolt pattern, which stayed constant over all years, the Hub bore on this generation is 64.1mm; the stock offset is roughly +50mm, which gives the wheels a tucked, sleek look while preserving crisp handling.

Although not too aggressive, this configuration gave drivers a good mix of daily usability and performance. Particularly when combined with 245 or 255 width tires and keeping a +45 to +50 offset, the suspension travel offered enough flexibility to upsize somewhat, thus owners typically went up to 19 or 20-inch rims for a bolder stance without major rubbing problems.

Though care should be taken with the offset, aftermarket wheels can substantially improve the stance. On an 8.5-inch wheel, a +40mm offset will poke out somewhat and can call for fender rolling for extreme configurations.

Watch tire height for those updating to prevent speedometer problems. Keeping the total diameter near to stock, ideal tire improvements include 245/50R18 or 255/45R19. Drivers seeking sharper graphics without compromising ride comfort or fuel economy find the first-generation RDX appealing since it can pull off a sporty configuration without suspension changes.

1st Gen: Factory Wheel & Tire Specs

Acura kept it basic throughout the levels from 2007 to 2012. The factory wheels are 18x7.5J using 235/55R18 tires. For modest off-road use as well as for cities, these offer decent traction and a pleasant ride. Tire grip is equally distributed with the SH-AWD system, and these specs perform great without taxing the drivetrain excessively.

1st Gen: Common Fitment Issues & Tips

Fitment problems with this generation primarily arise from owners either going too far or too low on the offset. You can run into fender rub if you dip below +40mm and choose an 8.5-inch width or larger. Stick with offsets between +45mm and +50mm to probably remain safe. Though unusual, spacer use can be beneficial if you are flush-mounting aftermarket wheels.

2nd Generation Acura RDX (2013 - 2018) Wheel Fitment

Acura changed wheel sizing and ride priorities in line with its more opulent feel of the second-generation RDX. Although the bolt pattern remains at 5x114.3, the total stance and clearance were somewhat more conservative to guarantee a better ride.

While top trims such the Advance or Tech packages occasionally had 19x8J wheels, most trim came with 18x7.5J wheels. Offering a solid mix of comfort and grip, factory tire sizes ranged from 235/60R18 to 235/55R19. The offset range shifted between +45mm and +55mm; the hub bore stayed at 64.1mm.

Higher-profile tires absorbed shocks better than their predecessors and helped lower road noise. Acura has significantly changed the suspension geometry to provide some extra wheel well space for more significant tire modifications.

For those wishing to modify wheels, 20x8.5J with a +40 to +45 offset performs effectively without any fender or strut conflict. Tire changes like 255/50R19 or 245/45R20 keep the appropriate rolling diameter and avoid altering ABS or traction control.

Those who desire a neat, sophisticated appearance but still want to add aftermarket wheels to liven up their SUV will find this generation perfect. Although it's not as forceful as Gen 1, the correct wheels and tires will entirely affect its road presence.

2nd Gen: Factory Wheel & Tire Specs

Top-tier trims used 19x8 wheels with 235/55R18 tires; standard RDXs used 18x7.5 wheels with 235/60R18 tires. Here Acura gave ride comfort first priority; these sizes strike a mix between luxury and practicality.

2nd Gen: Fitment Tips & Upgrades

Go no farther than 9 inches on wheel width unless you are comfortable with changes to upgrade safely. Many owners go for 255/45R20 on a 20x8.5 layout to enhance appearance without sacrificing ride quality. The SUV gains a sharper edge, and the wheels lie flush from a modest lowering using coilovers.

3rd Generation Acura RDX (2019 - Present) Wheel Fitment

Acura truly leveled out with the most recent RDX model. The wheel and tire sizing experienced significant improvements as well as in design, handling, and technology. Acura now leans toward bigger wheels to match the SUV's aggressive design, even if the bolt pattern is 5x114.3.

Usually riding on 19x8 wheels with 235/55R19 tires, base models have Higher trims or A-Spec versions include 255/45R20 tires and 20x8.5 wheels, therefore providing the SUV a broad, grounded stance. The hub bore is still 64.1mm; offsets run from +45mm to +50mm.

Upsize this generation simpler since they have somewhat greater wheel arch clearance and tighter suspension control. For a more aggressive look, many owners change to 20x9 or 20x9.5 wheels. You will be flush rather than rubbing with the correct offset around +40mm.

Here, choices from aftermarket sources shine. Deep concave or multi-spoke wheels fit the bold look of the RDX. Just make sure your speedometer or ride height sensors are not thrown off by keeping tire sizes within the 28-inch diameter range. 265/40R20 tires on 20x9 wheels are a common upgrade pairing that offers a clean, broad footprint free of clearance problems.

About wheels, the third gen RDX is mod-friendly. There's plenty of space to make it your own, regardless of your preferred style—performance-oriented or luxury cruise.

3rd Gen: Factory Wheel & Tire Specs

While the A-Spec trim receives 20x8.5 wheels and 255/45R20 tires, most trim starts with 19x8 wheels coupled with 235/55R19 rubber. Without sacrificing comfort, these give a sportier vibe. Perfect for regular commuting, the normal offset is +50mm.

3rd Gen: Fitment Tips & Aggressive Setups

Given a +40mm offset, this generation allows up to 20x9.5 wheels easily. If you are not mind minor fender modifications, wide tires like 265/40R20 or 275/40R20 can work. Closing the wheel gap and enhancing stance might come from lowering springs or coilovers.

Acura RDX Bolt Pattern Explained

From 2007 until current, every RDX model has the fairly popular 5x114.3 bolt pattern, which offers loads of wheel possibilities. The wheel has five lug holes thus, their distance from one another is 114.3mm. From the center of one lug, you can find the furthest lug across the circle.

Wheel shopping is much easier since the bolt pattern does not vary across generations. Still, avoid confusing bolt pattern compatibility with a guaranteed fit—offset, hub bore, and breadth still count. A wheel with the correct bolt pattern but the incorrect offset might result in rubbing, inadequate handling, or even suspension damage.

Many Honda and Toyota automobiles also use this bolt design, thus cross-shopping helps identify used or aftermarket wheels. Just always double-check all other fitting criteria before purchasing.

Acura RDX Offset Explained

Your Acura RDX's handling, appearance, and fit of aftermarket wheels depend much on offset. Imagine it as though the offset controls the distance your wheel sits within or outside the fender. Every version of the RDX carried a positive offset, meaning the wheel's mounting face is more toward the outside.

With a factory offset of about +50mm, the first Gen (2007–2012) RDX maintained the wheels neatly tucked beneath the fenders while preserving quick steering feedback. Acura engineers concentrated on a sporty arrangement, hence the wheels stayed rather close to one other to maintain handling qualities.

Acura polished everything in the second generation (2013–2018) to provide a more refined and pleasant ride. Based on trim level and factory wheel size, the offset range somewhat expanded from +45mm to +55mm. You will find less aggressive-looking fittings than Gen 1 because this allowed somewhat bigger wheels while maintaining a comfortable wheel arch clearance.

With most offsets ranging between +45mm and +50mm, the third generation (2019-present) RDX keeps this tendency. Acura provided more freedom for aftermarket enhancements since it provided bigger wheels stock—particularly on the A-Spec level. Especially when upgrading to 20x9 or 20x9.5 wheels, many owners who wish a more aggressive stance without rubbing choose +40mm to +45mm offsets.

Effects of offset go beyond just appearance. While too high an offset could interfere with brake calipers or suspension components, going too low on offset could create rubbing on the fender or wheel wells. Depending on your wheel width, a wise upgrade stays in the range of +38mm to +50mm for most aftermarket configurations. Keeping your RDX safe and smooth on the road will depend on matching the correct offset to provide you with that neat stance.

Acura RDX Hub Bore Size

Though sometimes disregarded, the hub bore is equally important to the bolt pattern and offset. The hub bore is the center hole on the wheel that exactly matches the hub of your car. It helps to cut vibrations and focus the wheel. You will require hub-centric rings if the hub bore is overly large. Should it be too small, the wheel will simply not mount.

The hub bore for the Acura RDX stayed the same over all three models. The RDX runs a 64.1mm hub bore from 2007 to right now. If you stay within this family, this is fantastic news since it relieves you of concerns regarding modifications while switching wheels between model years.

Acura developed the hub size to fit its suspension and steering system exactly. Especially at highway speeds, a well fitting hub bore guarantees you won't experience undesired steering wheel vibration. If the center bore is larger than 64.1mm, you must use hub-centric rings to fill the gap between the wheel and the hub even if you find an aftermarket wheel with the proper 5x 114.3 bolt pattern.

Although they are cheap and easy to install, hub-centric rings are essential if you wish for a flawless ride. Ignoring them could cause vibrations that would feel like wheel imbalance even if your tires and wheels are exactly balanced.

Always be sure the hub bore of any wheel you are looking at matches or exceeds 64.1mm. Should it be bigger, get ready for some hub-centric rings. Whatever generation, this basic attention to detail helps maintain the riding qualities Acura designed into the RDX.

Acura RDX Tire Size Guide

Things get complicated in tire sizing. Different tire sizes matched each iteration of the RDX's suspension, powerplant, and appearance. Maintaining speedometer accuracy, handling, and comfort calls for the correct tire size.

Overall trim, the first generation (2007–2012) used 235/55R18 tires. For the sportier SH-AWD system, this size strikes a mix of comfort and fast handling. Going with aftermarket wheels for a more grounded look without compromising clearance, some owners upgrade to 245/50R18 or even 255/45R19.

Acura provided two tire sizes based on trim level in the second generation (2013–2018). While higher trims, including optional 19-inch wheels, came with 235/55R19 tires, most trims used 235/60R18 tires. Acura turned toward larger profile tires in this generation to absorb shocks better and offer a smoother, more pleasant ride. Many owners of aftermarket setups safely run 255/50R19 or 245/45R20 tires with the correct wheel.

Larger tires from the manufacturer were a bold move taken by the third generation (2019–present). Base models usually have 235/55R19 tires; A-Spec and other high trims come with 255/45R20 tires on 20-inch wheels. Larger setups are easily accommodated by the wheel arches on this model, and running 265/40R20 tires without any rubbing is typical among aficionados.

Always keep the total diameter closer to factory as you can. To maintain your rolling diameter properly, offset by a lower-profile tire if you widen the wheel diameter. This keeps speedometer mistakes away and stops the suspension from bottoming out.

Whether your desired daily comfort or a sporty vibe, proper tire size maintains your RDX looking clean and running as it should.

Wheel Fitment Tips for Acura RDX Owners

Selecting the correct wheel configuration for your Acura RDX goes beyond simply putting on the largest set you could come across. Appropriate fit is the harmony of safety, style, and utility. Although the RDX gives a lot of freedom across all generations, there is certain advice you should follow to prevent headaches.

First, while updating wheels, always take the offset into account. Although you might wish for a wider stance, increasing the offset too low could create rubbing on the suspension components or possibly the fender liners. Depending on wheel width, staying between +38mm and +50mm is usually a good estimate for all generations.

Second, honor the general rolling radius. To keep a like total diameter when you upsize wheels, lower the aspect ratio (sidewall height). This preserves factory ride height, helps prevent speedometer mistakes, and keeps suspension problems free. Moving from an 18-inch to a 19 or 20-inch wheel, for instance, should be matched with a shorter sidewall tire.

Third, keep mind the hub bore. Always make sure the center bore of your wheels is 64.1mm; if it is greater, purchase hub-centric rings. This one easy action will maintain your ride smooth and remove vibrations at highway speeds.

Remember also load rating and TPMS compatibility. Not all aftermarket wheels are built to carry the weight of an SUV like the RDX. Always reinstall or program your TPMS sensors correctly; be sure the wheels you choose are made for crossover SUVs.

Good fitting is not limited to appearances. It's about riding seamlessly, handling well, and keeping your Acura secure. A well-selected configuration will turn heads with your RDX without sacrificing daily comfort or performance.

Aftermarket Wheel Recommendations

There are lots of choices depending on whether you want a sporty, luxury, or off-road-inspired design; the Acura RDX responds quite nicely to aftermarket wheels. Its popular 5x114.3 bolt pattern will help you discover no shortage of designs on the market.

Particularly on the first generation, using lightweight, multi-spoke wheels like those from Enkei or Konig can help you to improve the athletic character. These brands center on performance wheels that keep sharp handling without adding pointless weight.

Brands such Vossen, TSW, and Dub provide exquisite designs with clean finishes including gloss black, machined face, or matte silver for a more premium, luxury vibe fit for the 2nd or 3rd Gen. These wheels will keep OEM-plus fitment and provide your RDX a premium look.

The third generation RDX is the most tolerant in broad configurations if you want something more forceful. Many owners choose a flush or slightly aggressive stance with 20x9 or 20x9.5 wheels matched with 265/40R20 tires. Among those seeking strong designs with deep concave faces, rotiform and niche wheels are favorites.

Still, be careful when hunting. Unless you are ready to change fenders or run camber adjustments, avoid offsets less than +35mm. With an 8.5 to 9.5-inch wheel, most projects fall between +40mm and +45mm.

Finally, always try for respectable companies that create JWL/VIA-certified wheels. Wheel ratings for SUV loads help to guarantee safety since the RDX is a crossover rather than a lightweight coupe.

Fitment Comparison Table (All Generations)

This table provides a clear side-by- side picture of generational changes in wheel standards. Acura kept with the 5x114.3 bolt pattern and 64.1mm hub bore across all models, therefore simplifying wheel compatibility. To fit the change from sportiness (Gen 1) to luxury (Gen 2) and back to a mix of both, rim width, diameter, and tire profiles varied mostly over the years.

As long as you compensate for offsets and tire profiles, you may theoretically swap wheels across generations, whether you are cross-shopping wheels or hunting for old sets. On Gen 1 specifically, avoid combining excessively aggressive wheels without first checking clearance.

FAQs 

Can I use wheels from newer RDX models on older ones?

In terms of technical correctness, certainly Wheels can be swapped across generations since every generation uses the identical 5x 114.3 bolt pattern and 64.1mm hub bore. To prevent clearance problems, though, you need to confirm offset and tire size.

Will aftermarket wheels void my warranty?

Usually, none. Unless they cause a problem, installing aftermarket wheels will not void your manufacturing warranty. Always select correctly rated wheels and maintain the TPMS sensors in operation.

What's the biggest wheel I can fit without modifications?

You can install up to a 20x9 wheel with a +40 to +45mm offset without irritating most versions. If you don't drastically lower the car, you can even use 20x9.5 with 265/40R20 tires on the third Gen.

Do I need hub-centric rings when using aftermarket wheels?

Indeed, you should use hub-centric rings to avoid vibrations and guarantee appropriate mounting if the center bore of the wheel is more than 64.1mm.

Will changing my wheel size affect ride comfort?

Exactly. Usually having lower-profile tires, upsizing wheels implies the ride will be rather stiff. Choose a wheel based on whether you give appearance, comfort, or handling top priority.

Conclusion

One of those rare SUVs that strikes a mix between sportiness, luxury, and daily utility is the Acura RDX; the correct pair of wheels will accentuate its appearance and performance. Ensuring you maximize your improvement without compromising comfort, safety, or drivability requires knowing the proper bolt pattern, offset, hub bore, and tire sizing.

By following the 5x114.3 bolt pattern and 64.1mm hub bore, Acura kept things rather simple for all three generations. For owners wishing to replace or upgrade wheels, this consistency helps to ease concerns about serious compatibility problems. From the cutting, sporty first-generation to the sophisticated and tech-loaded third-generation, the wheel diameters, offsets, and tire profiles changed to fit each generation's characteristics.

Whether your upgrade is for performance or appearance, keep in mind that appropriate fitment goes beyond simply bolting on the first set of wheels you come across on the internet. Maintaining optimal handling, speedometer accuracy, and suspension geometry, always attempt to match your offset, validate hub bore compatibility, and apply appropriate tire sizes.

Your Acura RDX will not only look better but also feel more responsive and confident on the road with the correct wheel and tire combination. Moreover, the popularity of the 5x 114.3 bolt pattern will provide you with lots of fashionable choices from leading manufacturers.
