The 2022 Subaru Trucks Ascent is a modern three-row family hauler built to balance everyday comfort, all-weather confidence, and the extra space many crossover buyers need. Its tire fitment reflects that dual-purpose character, with 18-inch and 20-inch radial sizes depending on trim. This Ascent uses either 245/60R18 or 245/50R20, so the first step is matching the tire to the exact sub-model and wheel diameter already on the vehicle. Once that is confirmed, the real choice becomes selecting the right road-going replacement within the proper size. Owners should also verify the actual wheel setup before ordering, especially if the vehicle has seen wheel or suspension changes.
Which Tire Size Is Right for The 2022 Subaru Trucks Ascent
The 2022 Subaru Trucks Ascent uses two primary tire sizes, and the correct one depends on sub-model and wheel diameter. Both are radial metric sizes, but one fits an 18-inch rim and the other fits a 20-inch rim, so identifying the exact trim and confirming the wheel already on the vehicle should come before comparing tire choices.
A 245/60R18 tire uses a 245-millimeter section width, a 60-series aspect ratio, radial construction, and an 18-inch rim diameter. On the 2022 Subaru Trucks Ascent, this size serves trims that use the 18-inch wheel setup and offers a modern replacement format familiar to current drivers. Its role on this vehicle is straightforward: maintain the intended fitment for Ascents equipped with 18-inch wheels rather than switching to a different rim diameter. Before choosing among available tires in this size, confirm that the vehicle has not been changed to another wheel package.
Fit(s): Limited, Onyx Edition, Premium, and Touring
Construction: Radial|Rim: 20 in
A 245/50R20 tire keeps the same 245-millimeter nominal width but uses a lower 50-series profile on a 20-inch rim, with radial construction throughout. For the 2022 Subaru Trucks Ascent, this size belongs to trims equipped with the larger wheel package and should be selected only when the vehicle is actually running 20-inch wheels. The lower-profile sizing changes the fitment path compared with the 18-inch setup, even though both sizes are close in overall diameter. Buyers should treat this as a trim- and wheel-specific replacement decision, not a universal Ascent size.
Sub-model fitment matters on the 2022 Subaru Trucks Ascent because tire size changes with trim and wheel package. Some versions use one dedicated size, while Premium models may appear with either fitment, making wheel confirmation especially important before selecting tires.

2022 Subaru Trucks Ascent Base
The 2022 Subaru Trucks Ascent Base uses the 245/60R18 radial fitment. That makes tire selection fairly direct, with the main task being confirmation that the vehicle still has its 18-inch wheel setup rather than an upgraded wheel package.
The 2022 Subaru Trucks Ascent Limited uses the 245/50R20 radial size. Tire selection should stay focused on the 20-inch fitment, with attention paid to matching the existing wheel diameter before comparing replacement options.
The 2022 Subaru Trucks Ascent Onyx Edition uses the 245/50R20 radial fitment. Owners shopping this trim should confirm that the vehicle is still on its 20-inch wheels, then compare tires within that size rather than cross-shopping the 18-inch setup.
The 2022 Subaru Trucks Ascent Premium can use either 245/50R20 or 245/60R18, depending on the wheel package on the vehicle. That makes wheel diameter the first thing to verify, since the correct tire choice follows the actual 18-inch or 20-inch setup.
The 2022 Subaru Trucks Ascent Touring uses the 245/50R20 radial size. Buyers should stay with that fitment unless the vehicle has been changed from its current wheel package, since the Ascent also appears in a separate 18-inch configuration on other trims.
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.
Frequently Asked Questions
Common questions for the 2022 Subaru Trucks Ascent usually come down to exact tire size by trim, 18-inch versus 20-inch wheel fitment, and what to inspect before putting replacement tires into regular road use.
Tire Size & Fitment
What tire size fits a 2022 Subaru Trucks Ascent?
The 2022 Subaru Trucks Ascent uses either 245/60R18 or 245/50R20, depending on the sub-model and wheel package. Base models use 245/60R18, while Limited, Onyx Edition, and Touring models use 245/50R20. Premium models can appear with either size.
The practical decision is not choosing between two interchangeable sizes, but confirming which wheel diameter is already on the vehicle. An 18-inch Ascent needs the 18-inch tire size, and a 20-inch Ascent needs the 20-inch tire size. Checking the sidewall on the current tires and verifying the wheel diameter before purchase helps avoid ordering the wrong fitment.
What size rim does a 2022 Subaru Trucks Ascent use?
The 2022 Subaru Trucks Ascent uses either an 18-inch or 20-inch rim, depending on trim. The 245/60R18 tire fits the 18-inch setup, and the 245/50R20 tire fits the 20-inch setup. Both sizes are radial metric fitments.
Rim diameter is the first fitment check because the tire must match the wheel exactly. Even though the two Ascent tire sizes are close in overall diameter, an 18-inch tire cannot be mounted on a 20-inch wheel, and a 20-inch tire cannot be mounted on an 18-inch wheel. Wheel changes by a previous owner can also alter what the vehicle needs today.
Do all 2022 Subaru Trucks Ascent sub-models use the same tire size?
No. The 2022 Subaru Trucks Ascent uses more than one tire size across its sub-model range. Base models use 245/60R18, Limited, Onyx Edition, and Touring use 245/50R20, and Premium models may use either size depending on the wheel setup.
That means trim name alone may not always be enough, especially on a Premium. A quick check of the tire sidewall or wheel diameter gives the clearest answer before shopping. Treat the Ascent as a trim-specific fitment vehicle rather than assuming every 2022 model uses one universal tire size across the lineup.
Choosing the Right Tire
What should I consider when choosing a tire for a 2022 Subaru Trucks Ascent?
Start with the exact size already required by the vehicle: 245/60R18 or 245/50R20. The 2022 Subaru Trucks Ascent uses radial metric tires, so the main selection factors are proper size, correct rim diameter, and whether the tire matches the trim's wheel package.
After the fitment is confirmed, think about how the Ascent is actually used. A family crossover that sees daily commuting, highway miles, and changing weather needs a tire that suits those conditions without straying from the proper size. It also helps to confirm that the vehicle still has stock wheels and that no suspension or wheel modifications have altered the fitment.
How do I choose between the available 245/60R18 and 245/50R20 tires for a 2022 Subaru Trucks Ascent?
The choice between 245/60R18 and 245/50R20 is determined by the Ascent's wheel diameter and sub-model, not by personal preference alone. A Base model uses 245/60R18, while several higher trims use 245/50R20, and Premium models may appear with either fitment.
Once the correct size is confirmed, compare tires within that size rather than cross-shopping the other Ascent fitment. Staying inside the proper size keeps the replacement process much simpler and avoids mismatch issues at the wheel. Checking the existing tire sidewall, wheel diameter, and any prior wheel-package change is the best way to narrow the choice correctly.
Does the lower-profile 245/50R20 mean the same thing as 245/60R18 on a 2022 Subaru Trucks Ascent?
No. Both sizes use the same nominal 245-millimeter width, but they are built around different wheel diameters and different aspect ratios. The 245/60R18 uses a taller sidewall on an 18-inch rim, while the 245/50R20 uses a shorter sidewall on a 20-inch rim.
For an Ascent owner, that means the two sizes belong to different wheel setups even though their overall diameters are close. The vehicle should stay with the size that matches its existing rim unless the wheel package has been intentionally changed. Verifying the actual wheel and tire already on the vehicle is more useful than comparing the numbers in isolation.
Restoration & Appearance
Does correct tire fitment matter for a 2022 Subaru Trucks Ascent?
Yes. Correct tire fitment matters on a 2022 Subaru Trucks Ascent because this model uses two different radial sizes tied to two different wheel diameters. Choosing 245/60R18 versus 245/50R20 is not just a styling decision; it depends on the actual trim and wheel setup on the vehicle.
On a late-model vehicle like the Ascent, proper fitment supports the look, stance, and everyday usability the vehicle was built around. The safest approach is to confirm the wheel diameter and current tire size before replacing anything. If the vehicle has aftermarket wheels, fitment should be checked against the actual setup rather than the trim name alone.
How does tire size affect the appearance of a 2022 Subaru Trucks Ascent?
Tire size has a visible effect on the 2022 Subaru Trucks Ascent because the vehicle appears with either an 18-inch or 20-inch wheel package. The 245/60R18 uses a taller sidewall, while the 245/50R20 presents a shorter sidewall around a larger wheel.
That difference changes the visual balance of the vehicle even when overall diameter stays close. Owners usually get the most coherent appearance by keeping the tire size matched to the wheel package already on the Ascent. Any move to a different wheel diameter should be treated as a separate fitment decision rather than a routine tire replacement.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2022 Subaru Trucks Ascent?
Yes. Modifications can affect tire fitment on a 2022 Subaru Trucks Ascent, especially if the vehicle has aftermarket wheels, altered offsets, suspension changes, or a different wheel diameter than its original trim setup. Those changes can alter which tire size is appropriate and how much clearance is available.
A modified Ascent should be checked at the wheel, not just by model year and trim. Confirm the actual rim diameter first, then look at wheel width, steering clearance, and space around the fenders and suspension. Even when the vehicle started with 245/60R18 or 245/50R20, a changed setup may need closer measurement before replacement tires are selected.
What should I inspect before driving a 2022 Subaru Trucks Ascent on new tires?
Before driving a 2022 Subaru Trucks Ascent on new tires, confirm that the size matches the wheel diameter and trim setup, then inspect the wheels for damage and the valve stems for condition. It also makes sense to check that lug hardware is correct and that inflation is set appropriately for the installed tires.
A quick walk-around after installation can prevent problems from being missed. Look for proper clearance at full steering lock, make sure there is no rubbing, and recheck pressure after the first period of use. If the Ascent has replacement wheels or prior suspension changes, another visual fitment inspection is worthwhile before settling into regular highway driving.
How often should tires on a 2022 Subaru Trucks Ascent be inspected?
Tires on a 2022 Subaru Trucks Ascent should be inspected regularly rather than only when replacement time arrives. A routine check for air loss, uneven tread wear, cuts, bulges, and sidewall damage helps catch problems early, whether the vehicle uses 245/60R18 or 245/50R20.
Monthly pressure checks are a sensible habit, and a closer visual inspection before longer trips adds another layer of protection. Uneven wear can also point to alignment, suspension, or wheel issues that deserve attention before the next tire purchase. Keeping the tires in the correct size and watching their condition over time helps preserve predictable everyday road manners.
