Acura ILX Tires

Acura ILX uses three tire sizes across the 2013-2022 production run: 205/55R16 for 2013-2014 applications, 215/45R17 for 2013-2022 applications, and 225/40R18 for 2016-2022 applications. Their wheel diameters are 16 inches, 17 inches, and 18 inches respectively, and those rim diameters must match the wheels on the car.

That means year alone is not always enough to choose correctly. A 2013 or 2014 Acura ILX may use either 16-inch or 17-inch fitment, while a 2016-2022 Acura ILX may use either 17-inch or 18-inch fitment, so check the existing tire size placard or the wheel diameter on the car before moving forward.

On an Acura ILX, 215/45R17 is a metric radial tire size. The 215 is the section width in millimeters, 45 is the aspect ratio or sidewall height as a percentage of width, R means radial construction, and 17 is the wheel diameter in inches.

That decoding matters because the final number is the actual rim size the tire fits, not just a styling cue. If your Acura ILX is one of the many years that could be equipped with another size, matching the full code rather than only the width or wheel diameter is the safest way to keep the intended proportions and wheel fit.

A 2016 Acura ILX has two tire sizes listed because that model year appears with two different wheel diameters: 215/45R17 on 17-inch wheels and 225/40R18 on 18-inch wheels. The split is a wheel-package difference, not two interchangeable sizes for the same wheel.

The practical step is to identify the actual wheel diameter on your 2016 Acura ILX before selecting a tire. If the car is still on its original-style wheels, the existing tire sidewall will usually confirm the size immediately; if the wheels have been changed, measure or verify the wheel diameter directly rather than assuming the larger size belongs on every car.

Acura ILX uses 16-inch, 17-inch, and 18-inch rim diameters across its production run. The 16-inch fitment appears on 2013-2014 cars with 205/55R16, the 17-inch fitment appears throughout 2013-2022 with 215/45R17, and the 18-inch fitment appears from 2016 through 2022 with 225/40R18.

Because more than one rim diameter can appear in the same model year, the wheel itself is the deciding factor. Verify the car’s current wheel size first, then match the tire size to that wheel diameter exactly; a 17-inch tire will not fit an 18-inch wheel, and a 16-inch tire will not fit either.

The correct tire size for an Acura ILX is confirmed by matching the model year to the wheel diameter actually fitted to the car. Across the run, 2013-2014 cars may use 205/55R16 or 215/45R17, 2015 uses 215/45R17, and 2016-2022 cars may use 215/45R17 or 225/40R18.

Start with the size on the current tire sidewall, then confirm that it matches the wheel diameter and the car’s intended wheel package. That extra check matters most on years with two listed sizes, because replacing tires by year alone can send you toward a size that is correct for the model but wrong for the wheels on your specific Acura ILX.

Acura ILX tire offerings here include mostly blackwall radials, with one wide whitewall radial listed in 205/55R16. Blackwall is the dominant style across the 17-inch and 18-inch Acura ILX sizes, while the whitewall option appears only in the 16-inch fitment.

Most Acura ILX owners looking for a modern, factory-style appearance will stay with blackwall tires. The wide whitewall option is more of a custom visual statement than a typical late-model luxury sport sedan look, so it is worth deciding first whether you are aiming for a stock appearance or a personalized presentation.

The Acura ILX tire offerings here come from BFGoodrich, Michelin, American Classic, and Nitto. BFGoodrich appears across all three Acura ILX sizes, Michelin and American Classic appear in 205/55R16, and Nitto appears in 225/40R18.

Brand choice matters most after you have the size nailed down, because not every brand is represented in every fitment. Once the wheel diameter and tire size are confirmed on your Acura ILX, you can narrow the field by preferred look, intended driving character, and whether you want a conventional blackwall performance radial or the available whitewall presentation in the 16-inch size.

Acura ILX tires here are offered in several radial series, including g-Force Comp 2 AS, g-Force Sport Comp 2, g-Force Phenom T/A, Michelin SX MXX3 N2, American Classic Radial, and Nitto NT555 G2. These are all radial tires, but they differ by brand family, performance focus, and available appearance details such as blackwall versus wide whitewall styling.

The most useful way to sort them is first by size, then by the type of Acura ILX you are building or maintaining. A stock-looking daily driver may call for a straightforward blackwall radial, while a more personalized 16-inch car may lean toward the whitewall option, and an 18-inch application may lead you toward the performance-oriented series available in that larger fitment.

An Acura ILX stored on its tires should be kept in a cool, dry, dark environment with the tires clean and inflated to an appropriate storage pressure. Long exposure to sunlight, ozone sources, standing moisture, and repeated heat cycling can age the rubber even when the car is not being driven much.

If the Acura ILX will sit for extended periods, move it occasionally or place it on cradles or stands to reduce flat-spotting and concentrated loading. Storage care is especially important on lower-profile 17-inch and 18-inch fitments, where sidewall height is shorter and any pressure loss or long-term compression can show up sooner in ride quality.

Tires on an Acura ILX should be visually inspected regularly and given a closer hands-on inspection at least several times during the driving season, even if the car covers limited mileage. Look for irregular wear, cracking, punctures, impact damage, pressure loss, and any signs that one axle is wearing differently from the other.

Routine inspection is particularly useful on Acura ILX cars that alternate between daily use and long storage periods. Checking early helps catch alignment issues, aging rubber, or wheel damage before they become larger problems, and it is a sensible habit any time the car transitions from storage back to regular road use.

Tires on an Acura ILX should be replaced when age, cracking, hardening, impact damage, or structural concerns appear, even if the tread still looks usable. Collector habits are not the issue here so much as low annual mileage, because a lightly driven Acura ILX can still age its tires out before it wears them out.

The smart approach is to judge replacement by condition and age as much as tread depth. If an Acura ILX has spent years parked, has uneven wear, or shows sidewall deterioration, replacement should move ahead of appearance-based decisions, since a tire that looks acceptable at a glance may no longer deliver the road manners the chassis was designed to have.

Yes, the listed Acura ILX tires are modern radial road tires in the correct size families for the model’s 16-, 17-, and 18-inch wheel packages. Safety depends on selecting the exact size that matches the car’s wheels and using tires that are in sound condition, properly inflated, and free from age or impact-related damage.

The key point is that road safety starts with correct fitment, not simply with finding an Acura ILX tire by year. If your car is one of the years with two available wheel packages, choosing the wrong diameter tire for the wheels can stop the installation entirely or create obvious fitment problems before the car ever leaves the garage.

Before driving an Acura ILX, check tire pressure, confirm there is no visible sidewall or tread damage, and make sure the size on the car matches the wheel diameter being used. It is also wise to look for uneven wear that could point to alignment or suspension issues, especially on the lower-profile 17-inch and 18-inch sizes.

Those checks only take a few minutes and can prevent the most common tire-related problems on a modern compact sport sedan. If the Acura ILX has been stored, parked for a long period, or recently fitted with used wheels, add a close inspection for age cracking and bead seating before returning it to normal road use.

An Acura ILX should be driven at speeds appropriate to road conditions, tire condition, and the exact tire specification fitted to the car. The listed Acura ILX replacements are modern radial tires, but practical speed use still depends on correct inflation, sound condition, wheel integrity, and an overall vehicle condition that matches the car’s intended performance.

For a road-driven Acura ILX, the best practice is to think in terms of overall readiness rather than only the sidewall code. A fresh, properly fitted tire on the correct wheel is only part of the equation; suspension condition, alignment, brake health, and how long the car has been sitting all matter before using the car at sustained highway speeds.
