2022 Acura Tire Fitment Guide

2022 Acura vehicles use seven distinct sizes across three model lines. The ILX uses 215/45R17 or 225/40R18, the NSX uses 245/35R19 and 305/30R20, and the TLX uses 235/50R18, 255/40R19, or 255/35R20. Rim width guidance appears on several of those sizes: 215/45R17 fits 7.0 to 8.0 inches, 225/40R18 fits 7.5 to 9.0 inches, 245/35R19 fits 8.0 to 9.5 inches, 255/40R19 fits 8.5 to 10.0 inches, 235/50R18 fits 6.5 to 8.5 inches, and 255/35R20 fits 8.5 to 10.0 inches.

Because no single tire size fits the full 2022 Acura lineup, year and make alone are not enough to choose correctly. Buyers should confirm the exact model first, then verify the wheel diameter already on the car, and on the NSX also confirm whether the tire is for the front or rear axle. That step matters more here than on many classic applications because Acura used very different wheel-and-tire packages across the ILX, TLX, and NSX.

On a 2022 Acura, 215/45R17 is a metric radial size. The 215 is the nominal section width in millimeters, 45 is the aspect ratio, meaning the sidewall height is 45 percent of the section width, R identifies radial construction, and 17 is the wheel diameter in inches. On the 2022 Acura range, that size applies to the ILX rather than the TLX or NSX.

That code matters because it combines width, profile, construction, and wheel diameter into one fitment standard. If an ILX owner moves from a 17-inch wheel package to an 18-inch package, the tire code changes with it, so the size cannot be chosen by appearance alone. Matching all four parts of the code is the safest starting point before comparing brands, tread designs, or speed ratings.

No, 2022 Acura models do not share one common tire size. The ILX uses 17-inch or 18-inch fitments, the TLX spans 18-inch, 19-inch, and 20-inch fitments depending on version, and the NSX uses a staggered setup with 19-inch fronts and 20-inch rears. Every size in the 2022 Acura range is tied to a specific model rather than appearing across all three model lines.

That means fitment research for a 2022 Acura starts with model identification, not brand preference. Two cars wearing the same badge can have completely different wheel diameters, section widths, and front-to-rear requirements. If the car has aftermarket wheels, compare the actual tire sidewall code on the car and the wheel diameter before assuming it still matches the original Acura application.

Most 2022 Acura fitments here are offered in Blackwall form, which suits the modern factory appearance of the ILX and TLX and also works naturally on the NSX. The one size with broader sidewall variety is 305/30R20 for the NSX, where Blackwall, RWL, and Redline versions are available. That makes the rear NSX fitment the only place in this range where sidewall presentation changes as much as the brand choice.

For a stock-looking 2022 Acura, Blackwall is the most natural visual match. RWL and Redline options are more of a style decision than a fitment decision, and they can give the rear of an NSX a more customized look than Acura delivered from the factory. Owners aiming for a clean, contemporary appearance usually stay with Blackwall, while owners personalizing the car may prefer one of the accented sidewalls.

Three brands cover the 2022 Acura sizes here: BFGoodrich, Nitto, and Pro-Trac. BFGoodrich appears across every Acura size in this range except the accented-sidewall 305/30R20 options from Pro-Trac, while Nitto covers several 18-inch, 19-inch, and 20-inch performance sizes. Pro-Trac appears on the 305/30R20 rear NSX size with RWL and Redline versions in addition to more conventional Blackwall choices from other brands.

Brand choice on a 2022 Acura often comes down to which exact size your model uses and whether appearance matters as much as the basic fitment. ILX and TLX owners will mostly be comparing BFGoodrich and Nitto where applicable, while NSX owners may also weigh the visual impact of Pro-Trac's sidewall treatments on the rear. Once the correct size is confirmed, comparing speed rating, sidewall style, and load rating is usually more useful than comparing names alone.

On overlapping 2022 Acura sizes, BFGoodrich g-Force Phenom T/A and Nitto NT555 G2 differ in a few concrete ways. In 225/40R18, both reach 1,389 pounds at 50 psi on versions with published load figures, while the Nitto gives a 7.5 to 9.0 inch rim-width span and the BFGoodrich carries a similar 7.5 to 9.0 inch range. In 235/50R18, both reach 1,819 pounds at 50 psi, with the Nitto showing a 6.5 to 8.5 inch fit range and the BFGoodrich matching that same spread. In 255/35R20, the BFGoodrich carries a Y rating at 186+ mph, while the Nitto carries a W rating at 168 mph.

Those differences matter most when two products are available in the exact same Acura size and you want to narrow the choice by sidewall marking, published load figure, or top speed category. For many buyers, the speed symbol and visual style are the quickest ways to separate two otherwise similar modern radial options. Confirm the exact size first, then compare the published specs within that size rather than trying to compare one size or one model application to another.

Several 2022 Acura sizes have clear rim-width ranges. 215/45R17 works on 7.0 to 8.0 inch rims, 225/40R18 on 7.5 to 9.0 inches, 245/35R19 on 8.0 to 9.5 inches, 255/40R19 on 8.5 to 10.0 inches, 235/50R18 on 6.5 to 8.5 inches, and 255/35R20 on 8.5 to 10.0 inches. Those ranges are size-specific, so one Acura fitment should not be used as a stand-in for another.

The practical takeaway is to measure or verify the actual wheel before choosing a tire, especially if the car has aftermarket wheels or a previous owner changed the package. A tire may share the same diameter as another Acura fitment but still want a different wheel width because the section width and aspect ratio are different. Staying within the published rim-width range helps preserve the intended profile and tread shape.

These 2022 Acura fitments are modern radial applications, and one of the size markings explicitly shows TL on a 255/40R19 product, indicating tubeless construction. The other sizes are also modern ZR radial designs without tube-type markings. That places 2022 Acura fitments firmly in the contemporary tubeless category rather than in the tube-type world associated with many vintage applications.

Even with tubeless tires, valve stem condition still matters. If the wheels are being reused, inspect or replace the stems during mounting and make sure the wheel bead seats are clean and free of corrosion. On a modern Acura, air-loss complaints are more likely to come from stem age, wheel damage, or punctures than from any need for an inner tube.

A 2022 Acura should be stored away from direct sunlight, electric motors, welders, generators, and other ozone sources that accelerate rubber aging. Keep the car in a cool, dry area, maintain the tires at their proper pressure, and move the car periodically if it will sit for long stretches. Modern radials resist flat-spotting better than older bias-ply tires, but they still age faster when left under load in one position for months at a time.

Short-term storage usually benefits from simply keeping the tires clean, inflated, and shielded from heat and UV exposure. Longer storage may justify rolling the car occasionally or supporting it in a way that reduces constant loading, depending on the overall preservation plan. If the car is a low-mileage weekend Acura or an NSX that spends much of its life parked, storage habits can affect tire condition more than mileage does.

Tires on a 2022 Acura should be evaluated by age as much as by tread depth. A good collector and enthusiast rule is to begin watching them closely around five to seven years from the date code and to consider replacement by about ten years even if the tread still looks serviceable. That applies especially to cars that see low annual mileage, because rubber hardening and internal aging continue even when the car is rarely driven.

A lightly used ILX, TLX, or NSX can easily wear out its tires by time rather than mileage. Check the DOT date code on each tire, inspect for cracking or hardening, and avoid assuming that deep tread means the tire is still in ideal condition. Performance-oriented low-profile tires also tend to make age-related changes in ride and grip more noticeable as the rubber ages.

Tires on a 2022 Acura deserve a quick inspection before every drive and a more careful inspection before any longer outing. Look for pressure loss, punctures, sidewall cuts, bulges, uneven wear, and any cracking around the tread blocks or sidewall area. Because these are low-profile modern radials on relatively large wheels, curb damage and impact damage can also matter more than they might on a taller-profile touring tire.

That routine is especially important on a modern performance or sport-luxury Acura that may sit for stretches and then be driven briskly. If one tire repeatedly loses pressure, inspect the valve stem and wheel sealing surfaces along with the tire itself. Catching those issues early helps prevent avoidable damage and gives you time to match the replacement to the exact Acura size already on the car.

Yes, these 2022 Acura tire sizes are modern radial highway tires, and the published speed ratings shown here are W and Y depending on the size and product. W-rated tires carry a 168 mph ceiling, while Y-rated tires carry a 186+ mph ceiling. That covers normal U.S. highway use with a wide margin, and it also reflects the performance intent behind many ILX, TLX, and NSX fitments.

Safety on the road still depends on more than the speed symbol alone. Correct inflation, tire age, alignment condition, and whether the tire matches the exact wheel and axle position are just as important as the rating stamped on the sidewall. On the NSX in particular, front and rear sizes are not interchangeable, so using the proper staggered setup matters to road manners as much as outright speed capability.

Published maximum load-and-pressure figures vary by size and product on 2022 Acura applications, so one number should not be carried across the whole range. Examples include 215/45R17 at up to 1,356 pounds at 50 psi, 225/40R18 at up to 1,389 pounds at 50 psi, 245/35R19 at up to 1,433 pounds at 50 psi, 255/40R19 at up to 1,764 pounds at 50 psi, 235/50R18 at up to 1,819 pounds at 50 psi, and 255/35R20 at up to 1,609 pounds at 50 psi.

Those figures are tire-capacity references, not blanket instructions for everyday cold inflation pressure. For actual service pressure, start with the Acura door-jamb placard or owner's manual for your exact model and wheel package, then make sure the chosen tire's construction and rating support that use. If the car has been modified from stock, revisit the wheel-and-tire combination rather than assuming the factory pressure still applies unchanged.

Before a longer drive in a 2022 Acura, inspect all four tires for cuts, punctures, bulges, sidewall damage, and uneven wear, then confirm cold pressure and verify that every tire matches the correct size for the wheel position. On an NSX, make sure the front 245/35R19 and rear 305/30R20 positions have not been mixed. Also inspect the spare or mobility equipment if the car carries it, because a healthy main set of tires is only part of trip readiness.

A longer drive is also a good time to check wheel condition, torque, alignment feel, and any vibration that could point to balance or impact damage. Modern low-profile Acura tires can look fine at a glance while still hiding a problem from a pothole or curb strike. Taking a few extra minutes before departure is far easier than trying to sort out a fitment or damage issue once you are already on the road.
