The 2025 Subaru Trucks Solterra brings Subaru into the battery-electric crossover market with a layout that blends everyday utility, all-weather confidence, and modern wheel-and-tire sizing. For owners shopping this exact vehicle, tire choice is driven first by trim level, because the Solterra uses either 235/60R18 or 235/50R20 radial tires depending on sub-model. That means the main fitment decision is not vintage-style construction or bias-ply conversion, but confirming the correct wheel diameter before selecting a replacement. Once that is settled, the focus shifts to maintaining the intended overall stance, preserving clearance, and matching the tire to how the vehicle is actually driven.
Which Tire Size Is Right for The 2025 Subaru Trucks Solterra
The 2025 Subaru Trucks Solterra uses two primary tire sizes, and the correct one depends on the sub-model and its wheel diameter. Premium models use an 18-inch fitment, while Limited, Touring, and Touring Onyx Edition models use a 20-inch fitment. Before choosing a tire, confirm the exact trim and wheel size on the vehicle, because these two sizes are not interchangeable primary fitments.
Fit(s): Limited, Touring, and Touring Onyx Edition
Construction: Radial|Rim: 20 in
235/50R20 is a modern metric radial size where 235 identifies the section width in millimeters, 50 is the aspect ratio, R indicates radial construction, and 20 is the rim diameter in inches. On the 2025 Subaru Trucks Solterra, this size is used on 20-inch-wheel sub-models and keeps the tire in a low-profile modern crossover format. Its dimensions reflect a broad, contemporary footprint with a shorter sidewall than the 18-inch fitment. This is the size to evaluate when the vehicle is a Limited, Touring, or Touring Onyx Edition and still carries its original wheel diameter.
235/60R18 is a modern metric radial size with a 235-millimeter section width, a 60-series aspect ratio, radial construction, and an 18-inch rim diameter. On the 2025 Subaru Trucks Solterra, this fitment belongs to the 18-inch-wheel configuration and carries a taller sidewall than the 20-inch option while remaining close in overall diameter. That makes it a distinct trim-based fitment rather than a styling variation of the same wheel setup. This is the size to confirm when replacing tires on a Premium model or any Solterra that has retained the 18-inch factory wheel diameter.
Sub-model fitment matters on the 2025 Subaru Trucks Solterra because tire size changes with trim. The first step is identifying whether the vehicle is a Premium or one of the 20-inch-wheel trims, since that determines the correct primary size.

2025 Subaru Trucks Solterra Limited
The 2025 Subaru Trucks Solterra Limited uses the 235/50R20 radial fitment. Tire selection for this trim starts with confirming the 20-inch wheel setup, then choosing a replacement that preserves the intended low-profile modern crossover proportions.
The 2025 Subaru Trucks Solterra Premium uses the 235/60R18 radial fitment. That makes wheel diameter especially important at replacement time, since this trim does not share the 20-inch tire size used by the upper Solterra sub-models.
The 2025 Subaru Trucks Solterra Touring uses the 235/50R20 radial size. Owners replacing tires on this trim should verify that the vehicle still wears its 20-inch wheels before comparing tire choices or considering any alternate replacement within that fitment.
The 2025 Subaru Trucks Solterra Touring Onyx Edition also uses the 235/50R20 radial fitment. That keeps tire selection aligned with the other 20-inch Solterra trims, with the main priority being confirmation of the existing wheel package before replacement.
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)

Frequently Asked Questions
These FAQs for the 2025 Subaru Trucks Solterra focus on trim-based tire sizing, 18-inch versus 20-inch wheel fitment, replacement selection, and the checks that matter before road use or after wheel and suspension changes.
Tire Size & Fitment
What tire size fits a 2025 Subaru Trucks Solterra?
The 2025 Subaru Trucks Solterra uses two tire sizes: 235/60R18 and 235/50R20. The 235/60R18 size is used on the Premium sub-model, while 235/50R20 is used on Limited, Touring, and Touring Onyx Edition models. Both are radial fitments, but they are tied to different wheel diameters rather than being alternate versions of one universal setup.
The important step is matching the tire to the actual wheel on the vehicle. A Solterra with 18-inch wheels needs the 18-inch fitment, and a Solterra with 20-inch wheels needs the 20-inch fitment. If the vehicle has had wheel changes since new, check the installed wheel diameter before choosing a replacement tire.
What size rim does a 2025 Subaru Trucks Solterra use?
The 2025 Subaru Trucks Solterra uses either an 18-inch rim or a 20-inch rim, depending on sub-model. The 235/60R18 tire fits the 18-inch setup used on the Premium trim, while the 235/50R20 tire fits the 20-inch setup used on Limited, Touring, and Touring Onyx Edition models.
Rim diameter is the first fitment checkpoint because a tire must match the wheel exactly. The 18-inch and 20-inch Solterra fitments stay relatively close in overall tire diameter, but they are built around different wheels. Looking at the sidewall size code or measuring the wheel before ordering helps avoid choosing the wrong tire for the vehicle.
Why does the 2025 Subaru Trucks Solterra have more than one tire size?
The 2025 Subaru Trucks Solterra has more than one tire size because trim levels use different wheel packages. Premium models use 235/60R18 tires on 18-inch rims, while Limited, Touring, and Touring Onyx Edition models use 235/50R20 tires on 20-inch rims. The change is tied to the wheel diameter and tire profile, not to bias-ply versus radial construction.
That means tire selection starts with identifying the exact sub-model or checking the wheel itself. A buyer should not assume every Solterra uses the same replacement size just because the vehicles share the same model name. Confirming trim level, wheel diameter, and the size already mounted on the vehicle keeps the replacement process straightforward.
Choosing the Right Tire
What should I consider when choosing a 235/50R20 tire for a 2025 Subaru Trucks Solterra?
Start by confirming that the Solterra is one of the 20-inch-wheel trims, because 235/50R20 is used on Limited, Touring, and Touring Onyx Edition models. This size uses a modern radial format with a shorter sidewall than the 18-inch fitment, so maintaining the correct wheel diameter and replacement size is the main priority.
Once the size is confirmed, compare tires based on how the vehicle is used and whether the wheel setup is still stock. Owners should also look at overall tire dimensions, load suitability, and clearance around the fenders and suspension, especially if the vehicle has aftermarket wheels or any ride-height changes that could affect fitment.
What should I consider when choosing a 235/60R18 tire for a 2025 Subaru Trucks Solterra?
The first consideration is making sure the vehicle is a Premium model or otherwise still equipped with 18-inch wheels, because 235/60R18 is the Solterra's 18-inch primary fitment. This is a modern radial size with the same nominal section width as the 20-inch option, but it uses a taller sidewall and a different wheel diameter.
Selection should stay centered on correct fitment before anything else. Check the existing wheel diameter, compare the size on the current sidewall, and make sure any replacement tire suits the vehicle's actual wheel and suspension setup. If the Solterra has been modified, verify clearance at full steering lock and through normal suspension movement before finalizing a choice.
How do I choose between the available tire sizes for a 2025 Subaru Trucks Solterra?
The two Solterra tire sizes are not chosen by preference alone; they are chosen by the vehicle's wheel and trim configuration. Premium models use 235/60R18, while Limited, Touring, and Touring Onyx Edition models use 235/50R20. Both are radial sizes, but each one belongs to a specific rim diameter.
That means the decision is usually made by the vehicle already sitting in the driveway. Confirm the trim, read the size on the current tire, and check the installed wheel diameter before comparing replacement options. If the Solterra no longer has its original wheels, base the purchase on the actual wheel and clearance setup rather than the trim name alone.
Restoration & Appearance
Does correct tire fitment matter for a 2025 Subaru Trucks Solterra restoration or refurbishment?
Correct tire fitment still matters on a 2025 Subaru Trucks Solterra, even though this is a modern vehicle rather than a vintage restoration project. The right size preserves the intended relationship between the wheel, sidewall profile, and overall tire diameter. On this model, that means keeping 235/60R18 with the 18-inch setup and 235/50R20 with the 20-inch setup.
A refurbishment-minded owner should treat wheel diameter and trim configuration as the starting point. Even a visually similar tire can change the vehicle's stance or alter clearance if the wrong rim size is involved. Matching the tire size to the original wheel package helps maintain the Solterra's intended appearance and everyday road manners.
How does tire size affect the appearance of a 2025 Subaru Trucks Solterra?
Tire size affects the Solterra's appearance by changing the visual balance between wheel and sidewall. The 235/50R20 fitment creates a larger-wheel, lower-profile look, while the 235/60R18 fitment shows more sidewall around a smaller wheel. Both sizes are close in overall diameter, but they present the vehicle differently.
That is why appearance should be considered only after the correct wheel diameter is confirmed. A buyer replacing tires on a stock Solterra should stay with the size that matches the vehicle's trim and wheel package. If the vehicle has aftermarket wheels, compare the full setup carefully so the finished look does not create unwanted fitment issues.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2025 Subaru Trucks Solterra?
Yes, modifications can affect tire fitment on a 2025 Subaru Trucks Solterra. Wheel changes, offset differences, suspension alterations, and ride-height adjustments can all change how a 235/60R18 or 235/50R20 tire sits in the wheel opening. Even when the size code looks close to stock, the overall package may not behave the same once the wheel or suspension changes.
A modified Solterra should be checked for clearance at the fender edge, inner wheelhouse, and steering range before road use. It is also wise to confirm that the installed wheel diameter still matches the intended tire size. Small setup changes can have a noticeable effect on rubbing, steering clearance, and overall drivability.
What should I inspect before driving a 2025 Subaru Trucks Solterra on new tires?
Before driving a 2025 Subaru Trucks Solterra on new tires, inspect the size marked on the sidewall, confirm it matches the vehicle's wheel diameter, and check that all four tires are properly seated and inflated. A quick visual inspection should also cover sidewall condition, tread uniformity, valve stems, and any obvious interference with suspension or body components.
A short, careful test drive helps confirm that there is no rubbing, vibration, or pull. Recheck pressure after the first drive and look again for any contact marks inside the wheel openings. On a Solterra that has changed wheels or trim-level equipment over time, this final confirmation step is especially important.
How often should tires on a 2025 Subaru Trucks Solterra be inspected?
Tires on a 2025 Subaru Trucks Solterra should be inspected regularly, not only when replacement time arrives. Frequent checks for air pressure, tread wear, cuts, punctures, bulges, and sidewall damage help catch problems early. That matters whether the vehicle runs the 235/60R18 Premium fitment or the 235/50R20 size used on the higher trims.
Monthly visual inspections are a practical routine, with additional checks before longer drives or after impacts with potholes or curbs. Uneven wear can also point to alignment or suspension issues that affect tire life and road behavior. Vehicles that sit for stretches still need attention, since low use does not prevent pressure loss or age-related tire deterioration.
