The 2021 Subaru Trucks Crosstrek sits in the modern compact crossover class, blending everyday utility with the higher ride height and all-weather confidence that attract drivers to Subaru’s smaller platforms. For this exact model year, tire selection centers on two radial sizes tied to trim level: 225/60R17 and 225/55R18. That makes the first step confirming the vehicle’s sub-model and wheel diameter rather than comparing unrelated sizes. The available tire picture also leans heavily toward practical road use, with a Travelstar 225/60R17 option offered in a narrow whitewall configuration. Whether the goal is straightforward replacement or a more distinctive appearance, correct trim-level fitment comes first.
Which Tire Size Is Right for The 2021 Subaru Trucks Crosstrek
The 2021 Subaru Trucks Crosstrek uses two primary tire sizes, and the correct one depends on the exact sub-model and wheel diameter. Both are radial metric sizes, but one fits 17-inch wheels and the other fits 18-inch wheels, so confirming the trim level and the actual wheels on the vehicle is the first step before comparing tire style or product details.
225/60R17 is a metric radial size in which 225 identifies the nominal section width in millimeters, 60 is the aspect ratio, R indicates radial construction, and 17 is the rim diameter in inches. On the 2021 Subaru Trucks Crosstrek, this size serves the 17-inch wheel fitment used on selected sub-models. Available choices in this size include a Travelstar UN106 with a narrow whitewall presentation, which gives this otherwise modern size an appearance distinction beyond a plain black sidewall replacement. This is the size to evaluate when the vehicle has 17-inch wheels and the owner wants to balance correct fitment with style preference.
225/55R18 is a metric radial size with a 225-millimeter nominal section width, a 55-series profile, radial construction, and an 18-inch rim diameter. On the 2021 Subaru Trucks Crosstrek, this size belongs to sub-models equipped with 18-inch wheels, so it should not be treated as interchangeable with the 17-inch fitment. Its role is to match the wheel package used on those specific trims while keeping the overall tire diameter in the same general range as the 17-inch setup. This is the right size to pursue after confirming the vehicle is one of the 18-inch wheel configurations.
Sub-model fitment matters on the 2021 Subaru Trucks Crosstrek because tire size changes with the wheel package. Some trims use 17-inch wheels with one radial size, while others move to an 18-inch fitment, so confirming the exact sub-model helps narrow the correct replacement path quickly.

2021 Subaru Trucks Crosstrek Base
The 2021 Subaru Trucks Crosstrek Base uses the 17-inch tire fitment rather than the 18-inch setup found on other trims. That keeps replacement selection focused on the correct wheel diameter first, then on product details such as sidewall presentation and general road-use character.
The 2021 Subaru Trucks Crosstrek Hybrid uses the 18-inch radial tire fitment. Tire selection starts with confirming that 18-inch wheel package, then comparing tires within that size instead of cross-shopping 17-inch options that belong to other sub-models.
The 2021 Subaru Trucks Crosstrek Limited follows the 18-inch wheel and radial tire setup. That means the key fitment decision is staying with the correct 18-inch size and checking the actual wheels on the vehicle if it has ever been changed from stock-style trim equipment.
The 2021 Subaru Trucks Crosstrek Premium uses the 17-inch radial fitment shared with other selected trims. For replacement, the practical decision is less about multiple primary sizes and more about matching the correct 17-inch setup and choosing the tire style that suits the vehicle’s use.
The 2021 Subaru Trucks Crosstrek Sport uses the 17-inch radial tire package. That keeps the fitment path straightforward as long as the original wheel diameter is still in place, with the next choice centered on the available tire option and its appearance details.
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.

Common questions for the 2021 Subaru Trucks Crosstrek usually come down to trim-level tire size, 17-inch versus 18-inch wheel fitment, available product styling, and the basic checks that matter before daily driving or longer trips.
Tire Size & Fitment
What tire size fits a 2021 Subaru Trucks Crosstrek?
The 2021 Subaru Trucks Crosstrek uses two tire sizes: 225/60R17 and 225/55R18. Both are radial metric sizes, but they are tied to different sub-models and wheel packages rather than being universal across every Crosstrek in this model year.
The practical step is identifying the exact trim and confirming the wheel diameter already on the vehicle. Base, Premium, and Sport models use the 17-inch fitment, while Hybrid and Limited models use the 18-inch fitment, so selecting by year and model alone is not enough.
What size rim does a 2021 Subaru Trucks Crosstrek use?
A 2021 Subaru Trucks Crosstrek uses either a 17-inch or 18-inch rim, depending on the sub-model. The 225/60R17 fitment belongs to the 17-inch wheel setup, and the 225/55R18 fitment belongs to the 18-inch wheel setup.
Wheel diameter should be confirmed before choosing a replacement tire because a 17-inch tire cannot be mounted on an 18-inch wheel, and an 18-inch tire cannot be mounted on a 17-inch wheel. If the Crosstrek has aftermarket wheels, verify the actual rim size on the vehicle rather than relying only on trim name.
Do all 2021 Subaru Trucks Crosstrek sub-models use the same tire size?
No, the 2021 Subaru Trucks Crosstrek does not use one tire size across every sub-model. Base, Premium, and Sport models use 225/60R17, while Hybrid and Limited models use 225/55R18.
That split means tire selection starts with the exact sub-model or the actual wheel diameter. It also helps to check the existing tire sidewall and wheel size before ordering replacements, especially if the vehicle was purchased used or has had wheel changes that no longer match the original trim-level setup.
Choosing the Right Tire
What should I consider when choosing a 225/60R17 tire for a 2021 Subaru Trucks Crosstrek?
Start with the correct size, radial construction, and 17-inch wheel fitment. For the 2021 Subaru Trucks Crosstrek, 225/60R17 is used on Base, Premium, and Sport models, so the first requirement is matching that exact fitment rather than comparing it with the 18-inch alternative used on other trims.
After size is confirmed, look at details that affect how the tire suits the vehicle, including sidewall style, tire series, load figure, and rim compatibility. A Travelstar UN106 in this size adds a narrow whitewall appearance, which may matter if the owner wants a more distinctive presentation than a standard modern replacement tire.
What sidewall styles are available for 2021 Subaru Trucks Crosstrek tires?
Among the available options for the 2021 Subaru Trucks Crosstrek, 225/60R17 is offered with a narrow whitewall sidewall style. That gives this fitment a more distinctive look than the plain sidewall appearance many owners expect in a modern crossover tire size.
Sidewall style does not change the need to match the correct tire size and wheel diameter for the sub-model. Once fitment is confirmed, appearance becomes a legitimate part of the decision, especially for owners who want the Crosstrek to stand out without moving away from the proper radial size for the vehicle.
What tire series are available for the 2021 Subaru Trucks Crosstrek?
The available 225/60R17 product offering for the 2021 Subaru Trucks Crosstrek includes the Travelstar UN106 series. Tire series names help distinguish one product line from another, especially when the buyer wants to compare appearance details and core specifications within the correct size.
Series becomes most useful after the correct fitment is narrowed down by trim and wheel diameter. A 17-inch Crosstrek owner can compare the UN106’s style and specifications within 225/60R17, while an 18-inch Crosstrek owner should stay focused on the proper 225/55R18 size rather than using series name alone as the deciding factor.
Restoration & Appearance
Which tire should I choose for a period-style 2021 Subaru Trucks Crosstrek?
A period-style approach on a 2021 Subaru Trucks Crosstrek still starts with the correct modern radial size for the exact sub-model. The key decision is not vintage construction, but whether the owner wants a straightforward contemporary look or a tire with a more distinctive sidewall presentation within the proper fitment.
For the 17-inch setup, a narrow whitewall 225/60R17 offers a noticeable appearance choice without changing the basic size format the vehicle uses. The most convincing result comes from keeping the trim-specific tire size and wheel diameter correct first, then selecting the sidewall style that best matches the owner’s visual goals.
How does tire construction affect the appearance of a restored 2021 Subaru Trucks Crosstrek?
Tire construction is straightforward on the 2021 Subaru Trucks Crosstrek because the primary fitments are radial sizes rather than a mix of radial and bias-ply options. That means the appearance question is shaped more by the tire’s sidewall treatment and overall style than by a major construction change.
A radial tire can still look different from one product line to another, especially when a narrow whitewall is available in the correct size. Owners aiming for a clean, well-sorted presentation should keep the proper trim-specific size in place and use sidewall styling as the finishing detail rather than chasing an incorrect fitment for visual effect.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2021 Subaru Trucks Crosstrek?
Yes, modifications can affect tire fitment on a 2021 Subaru Trucks Crosstrek even when the original tire size is known. Changes such as aftermarket wheels, altered wheel width, suspension lowering or lifting, and body or fender modifications can all change how much space the tire has around the vehicle.
The safest approach is to confirm the actual wheel diameter and inspect clearances at full steering lock and normal ride height before changing tires. A Crosstrek that no longer has its original wheel package should be measured carefully so the selected tire size matches both the wheel and the vehicle’s current setup.
What should I inspect before driving a 2021 Subaru Trucks Crosstrek on new tires?
Before road use, check that the new tires match the correct size for the sub-model, seat properly on the wheels, and are inflated appropriately for the tire and vehicle setup. It is also worth inspecting the wheels themselves for damage and making sure valve stems are in good condition.
A short inspection drive should include listening for rubbing, feeling for vibration, and rechecking pressure after the tires have settled in. The same visit is a good time to look at alignment-related wear patterns on the old tires, since uneven wear can point to suspension or alignment issues that should be corrected early.
How often should tires on a 2021 Subaru Trucks Crosstrek be inspected?
Tires on a 2021 Subaru Trucks Crosstrek should be inspected regularly, not just when they look low or begin to ride poorly. Frequent visual checks for cuts, bulges, cracking, punctures, irregular wear, and pressure loss help catch problems before they affect handling or lead to premature replacement.
Routine inspection matters even more if the vehicle sees mixed seasonal use, rough roads, or long highway trips. A quick look at tread wear across the full width of each tire can also reveal whether alignment, inflation, or suspension issues are developing, which is especially useful when keeping the Crosstrek dependable for everyday driving.
