Acura ILX Wheel Fitment Guide

Introduction

The Acura ILX arrived for the 2013 model year as Acura’s entry-level sedan, a compact four-door built on Honda Civic underpinnings and aimed at buyers who wanted premium features in a smaller, more affordable package. It stayed in production through the 2022 model year, with two facelifts along the way, and it was eventually replaced by the Integra. Like every Acura, the ILX depends on the correct wheels for more than looks. The right fitment affects handling, braking, ride comfort, and even fuel economy, because the wrong wheels can add weight, change the steering feel, and upset the suspension geometry the car was designed around.

The particular wheel fitment needs for the Acura ILX are investigated in this guide. This guide provides all the information, including offset ranges, bolt patterns, hub bore diameters, and wheel size recommendations, whether you are replacing a damaged factory wheel or choosing aftermarket wheels for a sportier look. We also have advice on aftermarket wheels to enable you to acquire the ideal fit without sacrificing ride comfort or performance.

From its launch to its final model year, the ILX has a simple fitment story: three generations, one bolt pattern, one hub bore, and a narrow factory offset range shared across the whole run. This content will enable you to boldly negotiate the details and avoid the most common fitment mistakes.

Whether your update is for performance or style, this guide will be your reliable source for Acura ILX wheel fitment. Let us now address the particular requirements of the car, beginning with its first generation.

First Generation (DE: 2013–2015)

Built from 2013 to 2015, the first-generation ILX came with two engine choices and two factory wheel sizes. The 2.0L base model and the Hybrid rode on 16×6.5 inch wheels, while the sportier 2.4L model (Premium and Tech trims) came with 17×7 inch wheels. These wheels had an offset ranging from ET45 to ET50, with the 16-inch wheels at ET45 and the 17-inch wheels at ET50. The ILX had a 5×114.3mm bolt pattern, the Honda and Acura standard shared with the Civic, Accord, and TLX. Measuring 64.1 mm, its hub bore guaranteed a snug hub-centric fit for a variety of aftermarket wheels meant for Honda and Acura cars. M12x1.5 was the lug nut thread size, tightened to 80 lb-ft (108 Nm). The factory tire sizes are 205/55R16 on the 16-inch wheels and 215/45R17 on the 17-inch wheels, and the recommended cold tire pressure is 32 psi for the 16-inch setup and 33 psi for the 17-inch setup. The ILX can easily fit wheels from 16 inches to 18 inches for those looking for aftermarket wheels without major adjustments. Stated configurations should, however, keep a close rolling diameter to prevent interfering with the ABS and traction control systems.

On aftermarket wheels, owners of the first-generation ILX often step up to a 17-inch wheel with the 215/45R17 tire for a sharper look, or stay with the 16-inch setup for a little more comfort and cheaper tires. A 17×7 or 17×7.5 wheel at ET45 to ET50 keeps the stance clean and the fender rubbing away. Always confirm clearance, particularly if you are switching to bigger brakes, and match all four tires by make, type, and size.

Special Considerations

Although the first-generation ILX allows several wheel choices, make sure your selected wheels and tires fit the factory suspension. The Hybrid model shares the same hub geometry as the petrol models, so the fitment box is identical across the range, but lowering springs or coilovers could call for changes to stop rubbing. After any wheel modification, alignments should also be reviewed to preserve the best handling. Check the tire placard on the driver’s-door jamb for your exact car, because tire pressure can differ by trim and load.

Second Generation (DE Facelift: 2016–2018)

Built from 2016 to 2018, the facelifted ILX dropped the 2.0L and Hybrid models and standardized on the 2.4L engine, with the 16-inch wheel gone from the range. Depending on the trim level, stock wheel sizes are 17×7 inches or 18 inches on the A-Spec. The standard 17-inch wheels are 17×7 ET50, while the A-Spec offers 18×7.5 ET50 and a wider 18×8 ET45 wheel. These wheels had an offset ranging from ET45 to ET50, providing stability and clearance in harmony. The ILX kept the 5×114.3mm bolt pattern and the 64.1 mm hub bore from the first generation, so wheels from the earlier car bolt straight on. M12x1.5 was the lug nut thread size, tightened to 80 lb-ft (108 Nm). The factory tire sizes are 215/45R17 on the 17-inch wheels, 225/40R18 on the 18×7.5 A-Spec wheels, and 245/35R18 on the 18×8 A-Spec wheels, and the recommended cold tire pressure is 33 psi for the 17-inch and 225/40R18 setups and 36 psi for the 245/35R18 setup. The ILX can easily fit wheels from 17 inches to 19 inches for those looking for aftermarket wheels without major adjustments. Stated configurations should, however, keep a close rolling diameter to prevent interfering with the ABS and traction control systems.

On aftermarket wheels, A-Spec owners sometimes keep the 18-inch setup for the factory sporty look, while other owners move to a 19-inch wheel for a more aggressive stance. A 19×8 or 19×8.5 wheel at ET45 to ET50 with a 235/35R19 tire keeps the rolling diameter close to stock and the fender rubbing away. Always confirm clearance, particularly if you are switching to bigger brakes, and match all four tires by make, type, and size.

Special Considerations

Although the second-generation ILX allows several wheel choices, make sure your selected wheels and tires fit the factory suspension. The wider 18×8 ET45 A-Spec wheel sits further out than the standard 17-inch wheel, so if you are fitting that width to a non-A-Spec car, check the front fender clearance at full steering lock. Lowering springs or coilovers could call for changes to stop rubbing, especially with 19-inch wheels. After any wheel modification, alignments should also be reviewed to preserve the best handling. Check the tire placard on the driver’s-door jamb for your exact car, because tire pressure can differ by trim and tire size.

Third Generation (DE Facelift 2: 2019–2022)

Built from 2019 to 2022, the second facelift gave the ILX Acura’s diamond pentagon grille and updated Jewel Eye headlights, but the wheel fitment carried over unchanged from the 2016–2018 car. Depending on the trim level, stock wheel sizes are 17×7 inches or 18 inches on the A-Spec. The standard 17-inch wheels are 17×7 ET50, while the A-Spec offers 18×7.5 ET50 and a wider 18×8 ET45 wheel. These wheels had an offset ranging from ET45 to ET50, providing stability and clearance in harmony. The ILX kept the 5×114.3mm bolt pattern and the 64.1 mm hub bore used since the 2013 launch, so wheels from any earlier ILX bolt straight on. M12x1.5 was the lug nut thread size, tightened to 80 lb-ft (108 Nm). The factory tire sizes are 215/45R17 on the 17-inch wheels, 225/40R18 on the 18×7.5 A-Spec wheels, and 245/35R18 on the 18×8 A-Spec wheels, and the recommended cold tire pressure is 33 psi for the 17-inch and 225/40R18 setups and 36 psi for the 245/35R18 setup. The ILX can easily fit wheels from 17 inches to 19 inches for those looking for aftermarket wheels without major adjustments. Stated configurations should, however, keep a close rolling diameter to prevent interfering with the ABS and traction control systems.

On aftermarket wheels, owners of the final ILX often choose the factory 18-inch A-Spec wheels as a direct upgrade for a non-A-Spec car, since they share the same bolt pattern, hub bore, and offset range. A 19-inch setup with a 235/35R19 tire is the popular aftermarket step up, keeping the rolling diameter close to stock and the fender rubbing away. Always confirm clearance, particularly if you are switching to bigger brakes, and match all four tires by make, type, and size.

Special Considerations

Although the third-generation ILX allows several wheel choices, make sure your selected wheels and tires fit the factory suspension. Because the fitment is identical to the 2016–2018 car, the same cautions apply: the wider 18×8 ET45 A-Spec wheel sits further out than the standard wheel, so check front fender clearance at full steering lock when fitting it to a non-A-Spec car. Lowering springs or coilovers could call for changes to stop rubbing, especially with 19-inch wheels. After any wheel modification, alignments should also be reviewed to preserve the best handling. Check the tire placard on the driver’s-door jamb for your exact car, because tire pressure can differ by trim and tire size.

General Tips for Acura ILX Wheel Fitment

A good fit with the Acura ILX depends on knowing bolt patterns and offsets when choosing wheels. The ILX has a 5×114.3mm bolt pattern, hence the wheels have five lug nut holes set in a circle with a 114.3 mm diameter. This is the Honda and Acura standard, hence finding suitable aftermarket wheels is simpler if you search by this pattern rather than by model name alone, and wheels from the Civic, Accord, and TLX will often bolt on.

A wheel’s offset sets its distance from the hub of the vehicle. Positive offsets, that is, ET45 to ET50, found on the ILX suggest that the wheel mounting surface is nearer the outside of the wheel. Selecting an offset outside the advised range could cause problems including rubbing against suspension parts or stretching too far past the fender.

Check the hub bore size always as well. With 64.1 mm as the ILX standard, the hub will fit snugly without requiring centering rings. Hub-centric rings can aid in keeping stability if utilizing larger bore wheels, which many universal aftermarket wheels have.

Common Fitment Issues

One of the most often occurring problems when switching to bigger wheels or reduced offsets is rubbing. Think about the following to help avoid this:

• As you upsize, keep a similar rolling diameter to avoid ABS faults and speedometer mistakes.
• Wheel spacers should be used carefully since they change the offset and stress the hub bears.
• Make sure, particularly on cars with bigger brakes, aftermarket wheels clear the brake calipers.
• A wider bore wheel without hub-centric rings can cause vibration at highway speed, so fit rings sized to 64.1 mm.

Conclusion

Selecting appropriate wheels for your Acura ILX is about maintaining the performance and safety integrity of your car, not only about appearance. Knowing specifics like wheel diameters, offsets, bolt patterns, and hub bores guarantees a flawless fit whether you drive a 2013 launch car or a final 2022 model.

With advice for both OEM replacements and aftermarket enhancements, this guide has led you through the fitment of the ILX’s three generations, from the 16- and 17-inch wheels of the first generation to the 17- and 18-inch wheels of the facelifted cars. Remember how your wheel selection affects general ride quality, brake clearance, and suspension geometry. See a wheel fitment specialist in doubt to identify the ideal fit for your requirements.

Your Acura ILX is deserving of the best; you may improve its appearance, feel, and performance with the correct wheels. Having all the information now, it’s time to make a wise choice and get your ILX the upgrade it deserves!
