Subaru’s 2024 lineup reflects the brand’s modern mix of all-weather family utility, compact crossover practicality, and EV experimentation, even if the "Trucks" label here covers vehicles that are primarily crossovers and SUVs. In one model year, 2024 Subaru Trucks spans the three-row Ascent, the versatile Crosstrek and Forester, and the electric Solterra, so tire choice depends heavily on which model you own. Across four models, six radial sizes appear, and several are model-specific while Crosstrek and Forester share the same fitments. The first step is to confirm your exact model and wheel diameter, then match the correct metric radial size before comparing individual tire options.
Which Tire Size Is Right for Your 2024 Subaru Trucks
Six tire sizes are used across 2024 Subaru Trucks vehicles, and they vary by model rather than carrying across the full lineup. The real decision starts with confirming the correct model and wheel diameter, since these are all metric radial sizes but they do not all fit the same wheels. Understanding that distinction before choosing a product saves time and helps ensure the right match.
Year(s): 2024|Fit(s): Ascent|Construction: Radial|Rim: 18-in rim
245/60R18 is a metric radial size with a 245-millimeter section width, a 60-series aspect ratio, and an 18-inch rim diameter. This size is specific to the Ascent rather than universal across 2024 Subaru Trucks, and no product assortment is present here to compare brands, sidewall styles, or speed ratings. It is the size to focus on if your Ascent rides on 18-inch wheels. Confirm the wheel diameter on the vehicle before moving on to brand or tread-pattern preference.
Year(s): 2024|Fit(s): Ascent|Construction: Radial|Rim: 20-in rim
245/50R20 is a metric radial size with a 245-millimeter section width, a 50-series aspect ratio, and a 20-inch rim diameter. This size is also Ascent-specific, giving that model a second wheel-and-tire package that differs from the rest of 2024 Subaru Trucks. Buyers with 20-inch Ascent wheels should stay with this size when comparing replacement options. Checking the tire sidewall on the vehicle is the quickest way to separate it from the 18-inch Ascent fitment.
Year(s): 2024|Fit(s): Crosstrek, Forester|Construction: Radial|Rim: 17 in
225/60R17 is a metric radial size with a 225-millimeter section width, a 60-series aspect ratio, and a 17-inch rim diameter. Travelstar offers this size with a narrow whitewall sidewall style, and the available example carries a T speed rating with a 118 mph ceiling and a 1,709-pound maximum load at 44 psi. This size is shared by Crosstrek and Forester models equipped with 17-inch wheels, so it is a practical crossover fitment rather than a make-wide one. Buyers should still confirm whether their vehicle has the 17-inch or 18-inch package before choosing.
Year(s): 2024|Fit(s): Crosstrek, Forester|Construction: Radial|Rim: 18-in rim
225/55R18 is a metric radial size with a 225-millimeter section width, a 55-series aspect ratio, and an 18-inch rim diameter. This size is used by Crosstrek and Forester models with 18-inch wheels, and no product range appears here for a brand, sidewall, or speed-rating comparison. It suits owners who need the larger-wheel fitment for those shared Subaru crossover applications. Verifying the wheel diameter is essential because it is not interchangeable with the 17-inch option.
Year(s): 2024|Fit(s): Solterra|Construction: Radial|Rim: 20-in rim
235/50R20 is a metric radial size with a 235-millimeter section width, a 50-series aspect ratio, and a 20-inch rim diameter. This is a Solterra-specific fitment within 2024 Subaru Trucks, so it should be matched to that EV model and its 20-inch wheel package. No product assortment is present here to compare sidewall styling, tube status, or speed ratings within the size. Solterra owners should confirm the exact wheel package on the vehicle before narrowing the search further.
Year(s): 2024|Fit(s): Solterra|Construction: Radial|Rim: 18-in rim
235/60R18 is a metric radial size with a 235-millimeter section width, a 60-series aspect ratio, and an 18-inch rim diameter. Like the 20-inch option, this size is specific to the Solterra rather than shared across the 2024 Subaru Trucks range. It is the correct starting point for Solterra models fitted with 18-inch wheels. Confirm the sidewall marking on the vehicle so you stay with the proper diameter and profile.
Four models are covered for 2024 Subaru Trucks, and tire size varies by model rather than staying consistent across the lineup. Crosstrek and Forester share the same two sizes, while Ascent and Solterra each use their own pair of model-specific fitments. Select your model below to narrow the search to the right wheel diameter, size history, and applicable tire options.
2024 Subaru Trucks Ascent
The Ascent is Subaru’s largest family-oriented SUV, built around three-row practicality and a more substantial footprint than the brand’s compact models. Its tires mount on either 18-inch or 20-inch rims depending on the wheel package, so Ascent owners need to identify that package first before comparing replacements.
The Crosstrek sits at the smaller, adventure-ready end of Subaru’s modern lineup, blending hatchback proportions with crossover ride height and all-weather appeal. It uses either 17-inch or 18-inch rims, and those same fitments are shared with the Forester for this model year.
The Forester remains one of Subaru’s core compact SUVs, known for upright packaging, visibility, and broad everyday utility. For 2024, its tires mount on either 17-inch or 18-inch rims, sharing both of its fitments with the Crosstrek rather than the larger Ascent or electric Solterra.
The Solterra represents Subaru’s battery-electric entry, with sizing needs that differ from the brand’s gasoline crossovers. It uses either 18-inch or 20-inch rims, and both tire sizes are exclusive to Solterra within the 2024 Subaru Trucks range.
One product is available across six tire sizes for 2024 Subaru Trucks vehicles. The 225/60R17 size has one Travelstar radial option with a narrow whitewall sidewall style. Confirm your model, wheel diameter, and exact size before selecting a tire.
These FAQs focus on how 2024 Subaru Trucks sizes vary by model, how to decode the different metric fitments, and what to verify before replacing tires on modern Subaru crossovers and SUVs.
Size Basics & Fitment
What tire sizes fit 2024 Subaru Trucks vehicles?
2024 Subaru Trucks vehicles use six sizes across four models: Ascent uses 245/60R18 and 245/50R20, Crosstrek uses 225/60R17 and 225/55R18, Forester uses 225/60R17 and 225/55R18, and Solterra uses 235/60R18 and 235/50R20. Those sizes mount on 17-inch, 18-inch, or 20-inch rims depending on the model and wheel package. A 6.5J rim width appears with the available 225/60R17 example.
The practical takeaway is that year and make alone are not enough for this lineup. You need the exact model and the wheel diameter already on the vehicle before comparing tires, because an Ascent, Forester, and Solterra can all carry different 18-inch or 20-inch fitments that are not interchangeable just because the wheel diameter sounds similar.
What does 225/60R17 mean on a 2024 Subaru Trucks tire?
On a 2024 Subaru Trucks tire, 225/60R17 is a metric radial code. The 225 is the nominal section width in millimeters, 60 is the aspect ratio, meaning the sidewall height is 60 percent of the section width, R identifies radial construction, and 17 is the wheel diameter in inches. On this year and make, that size fits certain Crosstrek and Forester applications.
That code matters because every part of it affects compatibility. A tire with the same 17-inch diameter but a different width or aspect ratio can change overall height, clearance, and appearance, so the sidewall marking on the vehicle should match the intended replacement size exactly unless you are deliberately making a vetted size change.
Do all 2024 Subaru Trucks models use the same tire size?
No, 2024 Subaru Trucks models do not all use the same tire size. Crosstrek and Forester share 225/60R17 and 225/55R18, but Ascent uses 245/60R18 or 245/50R20, and Solterra uses 235/60R18 or 235/50R20. Even where wheel diameters overlap, the width and aspect ratio can differ from one model to another.
That means the model badge matters just as much as the year. If you start with only "2024 Subaru" or even just the wheel diameter, you can easily end up comparing the wrong tire family, so it is smart to verify both the model name and the size molded into the existing tire before ordering replacements.
Buying the Right Tire
What sidewall styles are available for 2024 Subaru Trucks tires?
A narrow whitewall sidewall style is available in 225/60R17 for certain 2024 Subaru Trucks Crosstrek and Forester applications. That same product is a radial Travelstar tire, and no other sidewall style appears here for the remaining 2024 Subaru Trucks sizes. Because these are modern Subaru crossovers and SUVs, blackwall styling is often what owners expect visually even though specialty sidewall treatments can exist in select sizes.
Sidewall appearance is worth checking before you finalize a choice, especially if you want the tire to blend with a stock modern look. A whitewall can change the character of a Crosstrek or Forester noticeably, so buyers who care about appearance should compare the sidewall treatment as closely as the size, speed rating, and wheel diameter.
What brands make tires for 2024 Subaru Trucks vehicles?
Travelstar is represented for 2024 Subaru Trucks in the 225/60R17 size used on certain Crosstrek and Forester applications. The available example is the Travelstar UN106 radial with a 99T service description. No brand assortment appears here for the other 2024 Subaru Trucks sizes.
Brand comparison only becomes useful after you have narrowed the search to the exact size on your vehicle. If your Subaru uses one of the Ascent or Solterra-specific sizes, or the 18-inch Crosstrek and Forester fitment, start with the size and wheel package first, then compare the tire choices available in that exact specification.
How do I choose the right tire for my 2024 Subaru Trucks vehicle?
The right tire for a 2024 Subaru Trucks vehicle starts with the exact model and sidewall size already fitted to the vehicle. This lineup uses six different metric radial sizes, and several are unique to one model, while Crosstrek and Forester share two sizes. The available 225/60R17 example also shows how sidewall styling and speed rating can vary within a modern radial replacement.
Once the size is confirmed, compare details that affect how the tire suits your needs: wheel diameter, sidewall appearance, load capacity, and speed rating. That approach is more useful than shopping by make alone, because an Ascent on 20-inch wheels and a Forester on 17-inch wheels have very different replacement requirements even within the same model year.
Fitting & Setup
What rim width do 2024 Subaru Trucks tires require?
A 6.5J rim width appears with the available 225/60R17 tire used on certain 2024 Subaru Trucks Crosstrek and Forester applications. The same product mounts on a 17-inch rim diameter, which matches the tire’s sidewall code. No broader rim-width spread appears here for the other 2024 Subaru Trucks sizes.
Rim width should always be checked against the exact tire you plan to use, not borrowed from a different size in the lineup. Even when two tires share the same wheel diameter, the approved wheel-width range can change with section width and profile, so the manufacturer’s fitment guidance for the exact tire remains the final checkpoint.
Do 2024 Subaru Trucks tires require inner tubes?
The available 225/60R17 tire for 2024 Subaru Trucks does not carry a tube-type marking, which is consistent with a modern tubeless radial fitment. No conflicting tube-type example appears within that size here. The remaining 2024 Subaru Trucks sizes are also modern radial applications, but the exact sidewall marking should always be checked on the tire being considered.
That matters because tube use should follow the tire and wheel design, not assumption. If you are replacing a single tire or changing brands within the same size, confirm whether the sidewall is marked for tubeless use and make sure the wheel condition, valve stem, and sealing surfaces are suitable before installation.
Can the original 2024 Subaru Trucks wheels be used with all tire sizes?
Original 2024 Subaru Trucks wheels can only be used with tire sizes that match their diameter and application. A 17-inch Subaru wheel can accept the appropriate 17-inch tire size for the correct model, but it cannot take an 18-inch or 20-inch tire. The same rule applies across the Ascent, Crosstrek, Forester, and Solterra wheel packages.
Wheel diameter is the first gate, but it is not the only one. Width, profile, and model-specific fitment still matter, so the safest route is to match the exact size already specified for that model and wheel package rather than assuming that any Subaru wheel from the same year will interchange cleanly.
Maintenance, Storage & Longevity
How should I store a 2024 Subaru Trucks vehicle when the tires are fitted?
A 2024 Subaru Trucks vehicle should be stored in a cool, dry place away from direct sunlight, electric motors, welders, battery tenders, and other ozone sources that can age rubber prematurely. Keeping the tires properly inflated and moving the vehicle occasionally helps reduce flat-spotting during long static periods. Clean concrete or tire cradles are better than damp ground or oily surfaces.
Modern radials generally tolerate storage better than older bias-ply designs, but they still age from time, heat, and environment. If the vehicle will sit for months, checking inflation pressure periodically and rolling it enough to change the contact patch can help preserve ride quality and sidewall condition when it goes back into regular use.
How long do tires on a 2024 Subaru Trucks vehicle typically last?
Tires on a 2024 Subaru Trucks vehicle should be judged by age as much as tread depth, especially if the vehicle is lightly used. A sensible rule is to begin close inspection once tires reach roughly five to seven years of age and to treat around ten years as a serious replacement point regardless of remaining tread. The DOT date code on the sidewall tells you when the tire was made.
That age-based approach matters because many newer SUVs and crossovers accumulate less mileage than their tires’ rubber aging would suggest. A tire can still look usable from a distance yet have hardened compound, sidewall cracking, or internal age-related deterioration, so time in service deserves as much attention as miles driven.
How often should tires on a 2024 Subaru Trucks vehicle be inspected?
Tires on a 2024 Subaru Trucks vehicle should be inspected before every drive and again before any extended highway trip. Look for visible cracking, punctures, uneven wear, bulges, embedded debris, and pressure loss, and make sure tread wear is even across the axle. Valve stems should also be checked for age or damage during routine pressure service.
Frequent inspections help catch problems before they become ride, handling, or safety issues. Because these vehicles can use different wheel-and-tire packages even within the same model family, it is also smart to confirm that all four tires match in size and service type, especially after prior ownership changes or seasonal wheel swaps.
Safety & Road Use
Are 2024 Subaru Trucks tires safe for highway driving?
Yes, 2024 Subaru Trucks tires are designed as modern radial applications, which is the standard construction for contemporary highway use. The available 225/60R17 example carries a T speed rating, which corresponds to a 118 mph ceiling. Actual safe road speed still depends on the complete condition of the tire, the vehicle’s load, inflation pressure, alignment, and the condition of the vehicle itself.
For most normal interstate use, the broader concern is not whether a modern radial can handle highway travel, but whether the specific tire on the vehicle is correctly sized, properly inflated, and in good condition. A healthy, correctly matched tire on a well-maintained Subaru is far more important than chasing theoretical top-speed capability you will never use.
What inflation pressure should I use for 2024 Subaru Trucks tires?
Inflation pressure for 2024 Subaru Trucks tires should follow the vehicle placard or owner’s manual first, because Subaru’s recommended pressure is tied to the vehicle’s weight balance and intended use. The available 225/60R17 example carries a maximum load of 1,709 pounds at 44 psi, but that figure is the tire’s load reference point, not a blanket inflation recommendation for every 2024 Subaru Trucks model or size.
Use the exact pressure specified for your model and wheel package, then compare it against the tire manufacturer’s guidance for the product you choose. Do not transfer a pressure figure from a 17-inch Crosstrek or Forester tire to an Ascent or Solterra size, because the sizes, loads, and intended operating conditions differ across the lineup.
What should I check before taking a 2024 Subaru Trucks vehicle on a longer drive?
Before a longer drive in a 2024 Subaru Trucks vehicle, inspect all four tires and the spare for cuts, cracking, nails, bulges, irregular wear, and proper cold inflation pressure. Confirm that the tire size on each corner matches the model’s intended fitment and check that valve stems are sound and caps are present. If the vehicle has sat for an extended period, pay extra attention to pressure loss and flat spotting.
A longer trip is also the right time for a broader mechanical once-over. Tire condition is only one part of the picture, so brakes, fluid levels, suspension behavior, and alignment should be in good order as well. A modern Subaru crossover or SUV will reward that extra preparation with better ride quality, steadier tracking, and fewer surprises on the road.
