The 2024 Subaru WRX carries the modern turbo sport-sedan formula forward with all-wheel-drive traction, sharp responses, and a strong enthusiast following that still pays close attention to chassis setup. Tire choice matters on this car because fitment changes by trim, with 235/45R17 on the Base, 245/40R18 on Premium, Limited, and GT, and 245/35R19 on the TR. All three are radial metric sizes, but the buying decision goes beyond dimensions into wheel diameter, sidewall profile, and the kind of tire you want the car to wear. That makes it important to match the exact sub-model first, then compare the available brands, series, and sidewall treatments.
Which Tire Size Is Right for The 2024 Subaru WRX
The 2024 Subaru WRX uses three different primary tire sizes, and the right one depends on the exact sub-model and wheel diameter. Base models use a 17-inch radial, Premium, Limited, and GT use an 18-inch radial, and TR models use a 19-inch radial. Before choosing a tire, confirm the trim level and the actual wheel size on the car, especially if wheels have been changed.
A 235/45R17 tire is a metric radial with a 235-millimeter section width, a 45-series aspect ratio, and fitment for a 17-inch rim. On the 2024 Subaru WRX, this size is the primary fitment for the Base model and keeps a useful balance between sidewall height and responsive handling. Available choices in this size include BFGoodrich and Nitto options, all in blackwall form, with series such as g-Force Sport Comp 2, g-Force Comp 2 AS, and NT555 G2. This size is the right place to start when the car still wears its original 17-inch wheel setup.
A 245/40R18 tire is a metric radial that uses a 245-millimeter section width, a 40-series profile, and an 18-inch rim. This is the primary WRX fitment for the Premium, Limited, and GT, so it is the most widely shared size across the 2024 range. Product choice is broader here, with BFGoodrich, Nitto, M&H Racemaster, and Pro-Trac offerings, plus blackwall, redline, and raised white letter sidewall treatments across several series. It is the key size to compare carefully if your WRX uses factory-style 18-inch wheels or an aftermarket wheel package in the same diameter.
A 245/35R19 tire is a metric radial with a 245-millimeter section width, a lower 35-series profile, and fitment for a 19-inch rim. On the 2024 Subaru WRX, this size belongs to the TR, where the shorter sidewall creates a distinctly different fitment profile from the 17-inch and 18-inch setups. BFGoodrich and Nitto options are available in this size, all with blackwall styling and series including g-Force Comp 2 AS, g-Force Phenom T/A, and NT555 G2. This size should be chosen only after confirming the car is actually on the 19-inch wheel arrangement.
Sub-model fitment matters on the 2024 Subaru WRX because tire size changes across the lineup rather than staying uniform. The first step is identifying whether the car is a Base, Premium, Limited, GT, or TR and confirming that it still has the wheel diameter associated with that trim.

2024 Subaru WRX Base
The 2024 Subaru WRX Base uses the 235/45R17 radial size, making it the only trim in the range with a 17-inch primary fitment. Tire selection here centers on choosing among the available blackwall performance-oriented options while confirming the car still has its 17-inch wheel setup.
The 2024 Subaru WRX GT uses the 245/40R18 radial size shared with other 18-inch trims. That opens up a wider set of tire choices, so the decision becomes comparing brands, tire series, and sidewall appearance rather than sorting through multiple primary sizes.
The 2024 Subaru WRX Limited uses the same 245/40R18 radial fitment as the GT and Premium. With that size confirmed, attention can shift to the kind of tire presentation and construction details you want, including blackwall, redline, or raised white letter offerings in the available product range.
The 2024 Subaru WRX Premium also uses the 245/40R18 radial size, so its fitment path matches the other 18-inch trims. Choosing the right tire usually comes down to matching the car's actual wheel width and deciding which brand, series, and sidewall style best suits how the car is used.
The 2024 Subaru WRX TR uses a 245/35R19 radial tire, giving it the largest wheel diameter and lowest-profile primary fitment in the lineup. That makes wheel confirmation especially important before replacement, since a switch to or from this size affects both rim diameter and sidewall profile.
The tire sizes listed on this page assume factory-standard vehicle configuration. The following modifications may affect tire fitment and are not reflected in this guide:
Suspension changes (lowering, lift kits, spring replacements)
Body alterations (fender modifications, custom bodywork)
If your vehicle has been modified from factory specifications, verify tire clearance before purchase.
Best 2024 Subaru WRX Tires for Sale
Available 2024 Subaru WRX tire choices vary by trim-specific size, brand, and tire series, with BFGoodrich, Nitto, M&H Racemaster, and Pro-Trac represented. Most options are blackwall radials, while selected 245/40R18 tires add redline and raised white letter styling for a different look.
These FAQs focus on the exact tire sizes used across the 2024 Subaru WRX lineup, how trim level affects fitment, and what to compare when choosing replacement radials for 17-inch, 18-inch, or 19-inch wheel setups.
Tire Size & Fitment
What tire size fits a 2024 Subaru WRX?
The 2024 Subaru WRX uses three different tire sizes depending on trim. The Base uses 235/45R17, the Premium, Limited, and GT use 245/40R18, and the TR uses 245/35R19. All of these are radial metric fitments tied to different wheel diameters within the WRX lineup.
The practical step is matching the tire to the exact sub-model and to the wheels currently on the car. A WRX that has been fitted with different wheels from another trim or with aftermarket wheels may no longer match its original trim-based tire size, so checking the wheel diameter before replacement is important.
What size rim does a 2024 Subaru WRX use?
A 2024 Subaru WRX can use 17-inch, 18-inch, or 19-inch rims, depending on the trim. The Base uses a 17-inch rim with 235/45R17 tires, the Premium, Limited, and GT use an 18-inch rim with 245/40R18 tires, and the TR uses a 19-inch rim with 245/35R19 tires.
Rim diameter should be confirmed before choosing tires, because each WRX size is built around a different wheel. Tire sizes are not interchangeable across those diameters, and even when the overall tire dimensions are relatively close, the bead seat diameter must match the wheel exactly for safe mounting.
Do all 2024 Subaru WRX sub-models use the same tire size?
No. Tire size varies across the 2024 Subaru WRX range. The Base uses 235/45R17, the Premium, Limited, and GT share 245/40R18, and the TR uses 245/35R19. That means the lineup includes three distinct primary sizes rather than one universal fitment for every WRX trim.
Sub-model identification matters before comparing products, since the right tire is tied to both the trim and the wheel diameter. If the car has changed hands or has been modified, checking the sidewall size already on the car and confirming the wheel size can prevent ordering a tire meant for a different WRX configuration.
Choosing the Right Tire
What should I consider when choosing a 2024 Subaru WRX tire?
Start with the exact tire size that matches the trim and wheel diameter on the car: 235/45R17, 245/40R18, or 245/35R19. From there, compare the available radial options by brand, tire series, sidewall style, load figures where given, and rim-width specifications where those details are part of the tire listing.
The best comparison is not just size alone but how the tire matches the actual wheel setup and the role the car plays. A street-driven WRX, a weekend car, and a car wearing style-focused sidewalls can all lead to different product choices even when the primary tire size remains the same.
What sidewall styles are available for 2024 Subaru WRX tires?
Blackwall is the most common sidewall style across the available 2024 Subaru WRX tire sizes. In 245/40R18, there are also redline and RWL options, giving owners of the 18-inch fitment a wider appearance choice than the 17-inch and 19-inch sizes, which are represented here by blackwall tires.
Sidewall style does not change the tire size requirement, but it can change the overall presentation of the car. If appearance matters as much as fitment, the 18-inch WRX trims offer the broadest styling range, while Base and TR owners are choosing primarily among blackwall tires in their correct sizes.
What brands offer tires for the 2024 Subaru WRX?
BFGoodrich and Nitto appear across all three primary 2024 Subaru WRX sizes, while M&H Racemaster and Pro-Trac are represented in 245/40R18. The available series include g-Force Sport Comp 2, g-Force Comp 2 AS, g-Force Phenom T/A, NT555 G2, Drag Radial, and Street Pro III.
Brand choice should be weighed alongside the exact trim-specific size, sidewall style, and wheel compatibility. A broad brand lineup is most visible in the 245/40R18 fitment, so owners of Premium, Limited, and GT models have the greatest range when comparing different tire personalities and visual treatments.
Restoration & Appearance
How does tire construction affect the appearance of a 2024 Subaru WRX?
The 2024 Subaru WRX uses radial tires across all of its primary fitments, so construction choice is less about bias-ply versus radial appearance and more about how the tire's profile and sidewall treatment shape the car's look. A 17-inch, 18-inch, or 19-inch setup gives the WRX a noticeably different visual stance.
Appearance changes most through wheel diameter and sidewall style. Blackwall keeps a contemporary presentation, while the available 245/40R18 redline and RWL options create a more distinctive look. The key is keeping the tire size matched to the trim or to the actual wheel package on the car so style does not override fitment.
Does correct tire fitment matter for a 2024 Subaru WRX restoration or appearance-focused build?
Yes. Even on a modern performance sedan like the 2024 Subaru WRX, correct tire fitment has a major effect on stance, wheel fill, and the overall proportions of the car. Using the right trim-based size keeps the relationship between wheel diameter and sidewall height aligned with the way that version of the WRX was configured.
Appearance-focused builds still need fitment discipline. A different wheel package can change the visual result, but the tire should be chosen around the actual rim diameter and wheel width in use, with enough attention to clearance that the final look does not create rubbing or an obviously mismatched tire profile.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2024 Subaru WRX?
Yes. A 2024 Subaru WRX that has aftermarket wheels, suspension changes, or body modifications may not accept the same tire setup as a stock car, even if the trim originally used one of the standard sizes. Wheel diameter, wheel width, and the car's ride height can all influence what clears properly.
That matters most when replacing tires on a used WRX or one built for a specific purpose. Checking the wheel size already on the car, reading the current tire sidewall, and looking at fender and steering clearance helps prevent choosing a tire that matches the original trim but not the modified vehicle.
What should I inspect before driving a 2024 Subaru WRX on new tires?
Before road use, inspect the wheel diameter and condition, confirm the new tires match the car's actual setup, and check inflation pressure carefully. It is also smart to look for uneven wear patterns, suspension issues, and any signs that the previous tires were contacting the fender liner, strut area, or other components.
A short test drive should be followed by another visual check for rubbing, air loss, or unusual wear. On a WRX, steering feel and all-wheel-drive behavior make tire consistency especially important, so the basic inspection should include verifying that the replacement tires are the correct size for the trim and wheel package.
How often should tires on a 2024 Subaru WRX be inspected?
Tires on a 2024 Subaru WRX should be inspected regularly rather than only when tread looks low. Routine checks should include inflation pressure, tread condition, cuts, bulges, and any sidewall damage. It also helps to monitor for uneven wear that may point to alignment or suspension issues affecting the car's handling.
More frequent inspection makes sense if the WRX is driven hard, sits for long periods, or uses aftermarket wheels and suspension parts. A quick walkaround before longer drives and a closer inspection at service intervals can catch clearance problems, slow air loss, or damage early, before they become a road-use issue.
