2022 Subaru WRX Tires

The 2022 Subaru WRX uses two primary tire sizes. The Base model uses 235/45R17, while the GT, Limited, and Premium use 245/40R18. Both are radial tire fitments, but they are tied to different trim levels and different wheel diameters.

That means the first step is identifying the exact WRX sub-model and checking whether the car still has its original wheel size. A Base on 17-inch wheels calls for a different tire than an 18-inch GT, Limited, or Premium, so size selection should start with the wheel-and-trim combination rather than appearance or brand alone.

A 2022 Subaru WRX uses either a 17-inch or 18-inch rim, depending on trim. The Base uses a 17-inch rim with 235/45R17 tires, while the GT, Limited, and Premium use an 18-inch rim with 245/40R18 tires.

Rim diameter is the non-negotiable starting point because a 17-inch tire cannot be mounted on an 18-inch wheel, and the reverse is also true. Before selecting a tire, read the wheel size currently on the car, especially if it has been purchased used or modified, since wheel swaps can change the correct tire path completely.

The 2022 Subaru WRX has more than one tire size because trim levels use different wheel diameters. The Base is fitted with 235/45R17, while GT, Limited, and Premium models use 245/40R18. The difference is tied to configuration rather than an interchangeable one-size-fits-all setup.

That makes trim identification especially important when replacing tires on a used WRX or one that may no longer have its original wheels. Tire choice should follow the actual wheel diameter and current setup on the car, then narrow down to the right brand, series, and sidewall style within the correct size.

Start with the correct trim-specific size: 235/45R17 for the Base or 245/40R18 for GT, Limited, and Premium. From there, compare construction, rim-width compatibility, sidewall style, tire series, and any stated load figures that matter to how the car is driven and how you want it to present.

A buyer keeping a WRX close to its current street setup may focus on blackwall performance radials, while someone after a more distinctive look may pay attention to the available 18-inch redline or raised white letter choices. Matching the tire to the actual wheel size and intended use matters more than choosing by appearance alone.

Blackwall is the most common sidewall style available for 2022 Subaru WRX tires in both 235/45R17 and 245/40R18. In 245/40R18, there are also redline and RWL, or raised white letter, options through the Pro-Trac Street Pro III line.

That gives 18-inch WRX owners more room to shape the car's appearance without changing the primary size. Sidewall style should still come after confirming the correct wheel diameter and tire size, since a distinctive redline or raised white letter treatment only makes sense once the fitment and intended driving use are already sorted out.

BFGoodrich and Nitto offer 17-inch and 18-inch radial choices for the 2022 Subaru WRX. The 245/40R18 fitment also includes M&H Racemaster and Pro-Trac, giving the 18-inch trims a wider mix of performance-focused and appearance-oriented options.

Brand comparison is most useful after narrowing the search to the correct size for the car. Once the trim and wheel diameter are confirmed, it becomes easier to compare tire series, sidewall treatments, rim-width specifications, and stated load figures instead of treating every WRX tire option as though it belongs on every sub-model.

All primary fitments for the 2022 Subaru WRX are radial, so the appearance decision is not about bias-ply versus radial in this case. Instead, the visual difference comes more from sidewall treatment, tread character, and the wheel-and-tire proportion created by the 17-inch Base fitment versus the 18-inch fitment on other trims.

A WRX kept close to its original modern sport-sedan look will usually stay within its trim-correct size and then choose among blackwall, redline, or raised white letter styles where available. Appearance changes should never come at the expense of proper size, wheel compatibility, or clearance on a car that may already have aftermarket wheels or suspension changes.

Correct tire fitment matters because the 2022 Subaru WRX uses two different size-and-wheel combinations across its trims. A Base on 235/45R17 presents differently than a GT, Limited, or Premium on 245/40R18, so keeping the proper size is part of preserving the car's intended stance and proportions.

Appearance-focused owners can still make styling choices within the correct fitment, especially on 245/40R18 where sidewall options expand beyond blackwall. The smart approach is to confirm the trim, wheel diameter, and current setup first, then choose the tire series and sidewall look that supports the build without drifting into the wrong primary size.

Yes, modifications can affect tire fitment on a 2022 Subaru WRX. Aftermarket wheels, altered wheel widths, suspension lowering, alignment changes, or body modifications can all change how a 235/45R17 or 245/40R18 tire sits in the wheelwell and how much clearance it has during steering and suspension movement.

A WRX that no longer has its original wheels should be measured carefully before replacement tires are chosen. Check the actual wheel diameter, wheel width, and the space around the tire at full lock and through suspension travel, because the correct factory size for one trim does not automatically suit a modified version of the same car.

Before driving a 2022 Subaru WRX on new tires, inspect the wheel size, confirm the correct trim-specific tire size, and make sure the tires are mounted to compatible rims. It is also worth checking air pressure, valve stems, visible sidewall condition, and whether there is any rubbing at the fender, strut, or inner wheelwell.

A short initial drive followed by another visual check can catch issues early, especially on a car with non-original wheels or recent suspension work. Pay attention to vibration, pull, or contact marks, since those symptoms can point to mounting, balance, alignment, or clearance problems that should be corrected before regular road use.

Tires on a 2022 Subaru WRX should be inspected regularly, not just when tread looks low. Frequent visual checks for cuts, bulges, irregular wear, cracking, and air loss are important on any performance-oriented car, especially one that may see spirited driving, seasonal storage, or occasional use rather than a daily commute.

Inspection is also a good time to confirm that all four tires still match the car's intended size and wheel setup. A WRX benefits from catching wear or pressure issues early, because uneven condition can affect handling feel and road manners long before a tire looks obviously worn from a quick glance in the driveway.
