The 2025 Subaru WRX carries the current version of Subaru’s turbocharged sport sedan formula, blending all-weather confidence with sharp road manners in a package that still appeals to drivers who value a manual-sedan mindset. Tire choice matters here because the WRX uses two distinct primary radial sizes depending on trim: 245/40R18 or 245/35R19. That means the decision starts with confirming whether the car has the 18-inch or 19-inch wheel setup, then narrowing down brand, series, and sidewall style. Blackwall options dominate, but 245/40R18 also opens the door to redline and raised white letter styling for owners who want a more distinctive presentation.
Which Tire Size Is Right for The 2025 Subaru WRX
The 2025 Subaru WRX uses two primary tire sizes, and the right one depends on sub-model and wheel diameter. Most trims use 245/40R18 on an 18-inch rim, while the WRX tS uses 245/35R19 on a 19-inch rim. Before comparing tires, confirm the exact trim and wheel setup on the car, especially if wheels have been changed from stock.
245/40R18 is a metric radial size where 245 is the nominal section width in millimeters, 40 is the aspect ratio, R identifies radial construction, and 18 is the wheel diameter in inches. On the 2025 Subaru WRX, this size supports the 18-inch wheel setup used across several trims and keeps the selection focused on modern radial performance tires. Available choices include BFGoodrich, Nitto, M&H Racemaster, and Pro-Trac, with blackwall, redline, and RWL sidewall treatments depending on the tire series. It is the size to evaluate when the goal is matching the standard 18-inch fitment while choosing between road-focused, styling-oriented, or drag-oriented products.
245/35R19 is a metric radial size with a 245-millimeter nominal section width, a 35-series profile, radial construction, and a 19-inch wheel diameter. On the 2025 Subaru WRX, this size is tied to the 19-inch setup rather than the more common 18-inch arrangement used on other trims. Product choices here center on blackwall radial performance tires from BFGoodrich and Nitto, including different series within the same overall size. This is the size to confirm when the car wears 19-inch wheels, since the rim diameter must match before any further comparison of brand, load specification, or driving intent.
Sub-model fitment matters on the 2025 Subaru WRX because tire size changes with the wheel package. Most trims share the same 18-inch size, while the tS moves to a 19-inch setup, so confirming the exact trim is the first step before choosing a tire.

2025 Subaru WRX GT
The 2025 Subaru WRX GT uses the 18-inch radial fitment shared with several other WRX trims. Tire selection here is mainly about comparing available 245/40R18 products by brand, series, sidewall style, and intended use rather than sorting through multiple primary sizes.
The 2025 Subaru WRX Limited uses the same 18-inch radial tire size found on the GT and Premium. That keeps fitment straightforward, with the real choice coming down to whether the car needs a conventional blackwall performance tire or a more style-driven option such as redline or RWL.
The 2025 Subaru WRX Premium stays with the 18-inch radial setup rather than the 19-inch package used on the tS. A buyer shopping for this trim should focus on 245/40R18 options and verify the wheel setup if the car has been modified or upgraded after delivery.
The 2025 Subaru WRX tS uses the 19-inch radial fitment, separating it from the other listed WRX trims. That makes wheel-diameter confirmation especially important, since 245/35R19 selection centers on blackwall performance tires built for the larger rim package.
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.

Tire Size & Fitment
What tire size fits a 2025 Subaru WRX?
The 2025 Subaru WRX uses either 245/40R18 or 245/35R19, depending on sub-model. WRX GT, Limited, and Premium models use 245/40R18, while the WRX tS uses 245/35R19. Both are modern radial sizes, but they are tied to different wheel diameters, so they are not the same fitment decision.
The first thing to confirm is the exact trim and the wheel package currently on the car. A WRX with changed wheels may no longer match its original sub-model fitment, so check the actual rim diameter before selecting a tire. Once the correct size is confirmed, the remaining choice is brand, tire series, sidewall treatment, and intended use.
What size rim does a 2025 Subaru WRX use?
A 2025 Subaru WRX uses either an 18-inch or 19-inch rim, depending on trim. The GT, Limited, and Premium are paired with 245/40R18 tires on 18-inch wheels, while the tS uses 245/35R19 tires on 19-inch wheels. The tire size and rim diameter must match exactly.
That means the wheel itself should be verified before comparing tires, especially on a car that may have aftermarket wheels. Diameter is the non-negotiable starting point, and rim width also deserves attention when comparing specific products. Once the wheel size is confirmed, it becomes much easier to sort through the available radial options that suit the car.
Do all 2025 Subaru WRX sub-models use the same tire size?
No. The 2025 Subaru WRX GT, Limited, and Premium share 245/40R18, but the WRX tS uses 245/35R19. The difference is tied to the wheel package, so the WRX lineup does not use one universal tire size across all listed sub-models.
That distinction matters because moving between 18-inch and 19-inch fitments changes the tire size and the wheel diameter at the same time. A buyer should identify the exact trim first, then confirm the actual wheels on the car if anything has been changed. Once that is settled, tire shopping becomes a matter of choosing the right radial product within the correct size.
Choosing the Right Tire
What should I consider when choosing a 245/40R18 tire for a 2025 Subaru WRX?
Start with the fact that 245/40R18 is the primary size for the 2025 Subaru WRX GT, Limited, and Premium. Within that size, available choices vary by brand, tire series, sidewall style, rim-width specification, load figure where stated, and intended use, including conventional street performance options and a drag-oriented radial.
A useful approach is to match the tire to how the car is actually driven and how it should look. Blackwall choices keep the appearance modern and straightforward, while redline and RWL add more visual character. Rim-width compatibility should be checked against the wheel on the car, and any modified suspension or wheel offset deserves an extra clearance review before installation.
What sidewall styles are available for 2025 Subaru WRX tires?
Sidewall style depends on the size and product selected. Blackwall is the most common presentation across both WRX fitments, while 245/40R18 also includes redline and RWL options in the Pro-Trac Street Pro III series. The 245/35R19 choices shown stay with blackwall sidewalls.
That gives 18-inch WRX trims more room for visual customization without changing the primary tire size. Buyers who want a more understated look can stay with blackwall, while a redline or raised white letter sidewall can change the car’s overall presentation. The main thing is keeping the correct size and rim diameter first, then selecting the sidewall treatment that suits the build.
What brands offer tires for the 2025 Subaru WRX?
Available 2025 Subaru WRX tires include products from BFGoodrich, Nitto, M&H Racemaster, and Pro-Trac. Brand choice varies by size, with BFGoodrich and Nitto appearing in both 245/40R18 and 245/35R19, while M&H Racemaster and Pro-Trac are part of the 245/40R18 selection.
The practical difference is not just the brand name but the kind of product each brand brings to the size. Some options focus on mainstream street performance, some on appearance-oriented sidewall treatments, and one is built around drag-race use. It helps to narrow the decision by trim, then by intended use, then by details such as rim-width range, load information, and sidewall style.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2025 Subaru WRX?
Yes. Wheel changes, altered offset, suspension lowering, spring changes, and body modifications can all affect tire fitment on a 2025 Subaru WRX. That matters even when the tire size itself is correct, because the relationship between the tire, wheel, fender, and suspension can change from the original trim-specific setup.
A modified WRX should be checked for wheel diameter, wheel width, steering clearance, and fender clearance before a new tire is chosen. That is especially important when moving between the 18-inch and 19-inch trim setups or when using aftermarket wheels. Looking at the actual car, rather than assuming it still matches its original configuration, prevents many avoidable fitment problems.
What should I inspect before driving a 2025 Subaru WRX on new tires?
Before driving on new tires, inspect basic installation and condition items: correct size, proper wheel diameter, tire pressure, visible bead seating, lug torque, and any obvious sidewall or tread issues. On a 2025 Subaru WRX, it is also smart to confirm that the tire size matches the trim’s wheel package before the car goes back into regular use.
A short clearance check is worthwhile as well. Turn the steering from lock to lock, look for rubbing near the strut and fender liner, and pay attention to any contact points if the car has aftermarket wheels or suspension changes. After the first drive, recheck pressure and inspect for uneven wear or scuffing that could point to an alignment or clearance issue.
What should I check before a longer drive in a 2025 Subaru WRX?
Before a longer drive, check tire pressure, tread condition, visible cuts or bulges, and any signs of air loss. A 2025 Subaru WRX should also have matching tire sizes appropriate to its wheel setup, since the model uses either 245/40R18 or 245/35R19 depending on trim and rim diameter.
It also helps to inspect for uneven wear, which can point to alignment or suspension issues that become more noticeable on highway trips. A car with recent wheel or tire changes deserves a quick clearance review and a lug-torque check before departure. Catching those details early helps avoid vibration, rubbing, or pressure-related trouble once the drive is underway.
