2016 Acura ILX Tires

The 2016 Acura ILX uses two tire sizes depending on sub-model. The Base model uses 215/45R17, while the 2016 Acura ILX w/A-Spec Pkg. uses 225/40R18. Both are radial fitments, but they are tied to different wheel diameters, so they should not be treated as interchangeable choices across the whole ILX lineup.

The practical first step is confirming which version of the ILX is in front of you and checking the actual wheel diameter on the car. If the vehicle has aftermarket wheels or a changed wheel-and-tire package, match the tire not only to the model name but also to the installed wheel size before making a selection.

A 2016 Acura ILX uses either a 17-inch or 18-inch rim, depending on sub-model. The Base model is paired with a 17-inch fitment through the 215/45R17 tire size, while the w/A-Spec Pkg. uses an 18-inch fitment through the 225/40R18 size. Both sizes are modern radial formats built around those wheel diameters.

Rim diameter is the non-negotiable starting point because a 17-inch tire cannot be mounted on an 18-inch wheel, and an 18-inch tire cannot be mounted on a 17-inch wheel. It also helps to confirm rim width, especially if the car has non-stock wheels, since available products in each size are designed around specific width ranges.

No, the covered 2016 Acura ILX sub-models do not use the same tire size. The Base model uses 215/45R17, and the w/A-Spec Pkg. uses 225/40R18. Both are radial tires, but the fitment changes with the wheel package, so the correct tire depends on the exact sub-model and wheel setup.

That difference matters because the two sizes are built for different wheel diameters and slightly different tire proportions. A buyer choosing tires for an ILX should verify the trim package, inspect the wheels currently on the car, and avoid assuming that one size applies across the entire model range just because both belong to the same model year.

Start with the correct size for the exact 2016 Acura ILX sub-model: 215/45R17 for the Base model or 225/40R18 for the w/A-Spec Pkg. From there, compare the available radial tire series, wheel-width compatibility, and any load information that matters to your driving use. The tire choice should match the actual wheel diameter and the character you want from the car.

A buyer using the ILX as a regular street car may focus on all-season versus more performance-leaning product character, while another may care most about brand preference within the correct size. It also helps to confirm that the car still has the intended wheel package, since altered wheels can change the range of acceptable tires.

Tire choices for the 2016 Acura ILX include BFGoodrich in both primary sizes and Nitto in the 225/40R18 fitment. BFGoodrich covers the 215/45R17 and 225/40R18 sizes across several g-Force series, while Nitto adds the NT555 G2 for the 18-inch setup used on the w/A-Spec Pkg. model.

Brand comparison is most useful after the correct size has been confirmed. Once that is settled, the buyer can look at differences in tire series, intended use, wheel-width compatibility, and product specifications that matter for the car’s setup rather than choosing by brand name alone.

The 2016 Acura ILX is covered by several series depending on size, including BFGoodrich g-Force Sport Comp 2, g-Force Comp 2 AS, and g-Force Phenom T/A. In 225/40R18, the Nitto NT555 G2 is also available. These series give the ILX owner more than one modern radial option within the proper fitment range.

Series choice helps narrow the decision once the correct size is identified. Some buyers may want an all-season style option, while others may prefer a more sport-focused radial. Comparing series alongside wheel-width range, load figures where stated, and intended road use is a better approach than selecting on tread name alone.

A period-style approach on a 2016 Acura ILX still begins with the exact original-size format for the sub-model, since this is a modern compact sport sedan rather than a collector-era bias-ply application. That means 215/45R17 for the Base model or 225/40R18 for the w/A-Spec Pkg., both in modern radial form with blackwall presentation.

Appearance on a newer vehicle like the ILX is usually influenced more by wheel size and tire profile than by vintage sidewall treatments. Keeping the correct diameter, width class, and overall visual balance of the original fitment will usually matter more than chasing novelty, especially if the goal is a clean, proper factory-era look.

Yes, correct tire fitment matters because the 2016 Acura ILX uses specific low-profile radial sizes that shape the car’s stance and wheel-to-tire proportions. Using 215/45R17 on the Base model or 225/40R18 on the w/A-Spec Pkg. helps preserve the intended visual balance much better than substituting a random size with a mismatched sidewall height.

Buyers aiming for a clean original-style presentation should confirm the actual wheel package before replacing tires. Even small changes in profile can alter how the car sits and how full the wheel openings appear. If originality is especially important, compare the replacement tire’s overall look with period Acura sales materials or marque-specific references.

Yes, modifications can affect tire fitment on a 2016 Acura ILX even when the replacement tire is one of the correct original-size options. Aftermarket wheels, suspension changes, lowered ride height, or body alterations can change clearance at the fender, strut, or steering range. That matters especially because the ILX uses relatively low-profile radial sizes.

A modified ILX should be checked for actual wheel diameter, wheel width, and available clearance before a tire is chosen. It is also smart to inspect for rubbing marks or uneven tire wear that may signal a setup issue. Those checks are more useful than assuming the stock size will behave the same on a changed chassis.

Before driving a 2016 Acura ILX on new tires, inspect wheel condition, confirm the tire size matches the sub-model, and make sure each tire is mounted on the correct wheel diameter. It also helps to check air pressure, valve condition, and overall installation quality so the new tires start service under the right basic conditions.

Road use checks should also include tread and sidewall inspection after the first miles, especially if the car has been sitting or recently had wheel work performed. A short follow-up look for air loss, vibration, or contact marks around the wheel wells can catch fitment or installation issues before they become bigger problems.

Before a longer drive in a 2016 Acura ILX, confirm that the tires are the correct size for the car’s wheel package and that inflation is set properly for the intended use. Inspect tread depth, look for cuts or bulges, and check the sidewalls for impact damage or age-related deterioration that may not be obvious at a glance.

Longer trips also make wheel balance, alignment condition, and steady air retention more important. A quick inspection for uneven wear can reveal suspension or alignment issues that reduce tire life and drivability. On an ILX with aftermarket wheels, add a clearance check at full steering lock so highway use does not expose a preventable fitment problem.
