The 2020 Subaru Trucks Forester belongs to the modern crossover era, where everyday utility, all-weather confidence, and long-trip comfort matter as much as efficiency. For this exact model year, tire selection starts with two primary radial sizes: 225/60R17 and 225/55R18, with the correct choice tied directly to the vehicle’s sub-model and wheel diameter. That means the decision is less about vintage-style construction and more about confirming whether your Forester carries 17-inch or 18-inch wheels. Available product choice here also introduces a sidewall appearance option, which can matter if you want a more distinctive look while staying within the proper size.
Which Tire Size Is Right for The 2020 Subaru Trucks Forester
The 2020 Subaru Trucks Forester uses two primary tire sizes, and the right one depends on the exact sub-model and wheel diameter. Both fitments are radial, but one is built around a 17-inch rim and the other around an 18-inch rim, so confirming the wheel size is the first step before comparing tires or sidewall treatments.
225/60R17 is a metric radial size in which 225 is the nominal section width in millimeters, 60 is the aspect ratio, R identifies radial construction, and 17 is the rim diameter in inches. On the 2020 Subaru Trucks Forester, this size is used on 17-inch-wheel configurations and suits buyers looking for the proper modern fitment rather than a vintage construction choice. Available options in this size can vary by sidewall treatment and tire series, including a Narrow Whitewall Travelstar UN106. It is the size to evaluate when your Forester has the correct 17-inch wheel setup.
225/55R18 is also a metric radial size, using the same 225-millimeter nominal width but a lower 55-series profile on an 18-inch rim. For the 2020 Subaru Trucks Forester, this fitment belongs to specific 18-inch-wheel sub-models, so it should not be chosen simply because the section width looks similar to the 17-inch option. The lower-profile sizing changes the wheel-and-tire package even though overall diameter stays in a similar range. This is the size to focus on after confirming the vehicle carries the correct 18-inch wheels for its trim.
Tire fitment on the 2020 Subaru Trucks Forester varies by sub-model, and the split follows wheel diameter as much as trim level. Identifying the exact sub-model helps narrow the correct tire size immediately and prevents confusion between the 17-inch and 18-inch fitments.

2020 Subaru Trucks Forester Base
The 2020 Subaru Trucks Forester Base uses the 225/60R17 radial fitment on a 17-inch wheel package. That makes tire selection fairly straightforward once the wheel size is confirmed, with the main comparison shifting to available product style and specification details within that size.
The 2020 Subaru Trucks Forester Limited uses the 225/55R18 radial size, placing it with the 18-inch-wheel configurations rather than the 17-inch group. Tire choice here starts with staying in the correct 18-inch fitment before comparing product characteristics or appearance details.
The 2020 Subaru Trucks Forester Premium uses the same 225/60R17 radial size as the Base model. That shared fitment means buyers can focus on selecting the right tire within the proper size rather than sorting through multiple primary size possibilities.
The 2020 Subaru Trucks Forester Sport uses 225/55R18 radial tires, matching the 18-inch-wheel fitment used by other upper-trim configurations. Tire selection should begin with confirming the existing wheel setup, then comparing suitable options within that exact size.
The 2020 Subaru Trucks Forester Touring also uses the 225/55R18 radial fitment tied to an 18-inch rim. For this sub-model, the practical question is not which primary size fits, but which tire characteristics within that size best match the vehicle’s intended road use and appearance.
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 2020 Subaru Trucks Forester?
The 2020 Subaru Trucks Forester uses two primary tire sizes: 225/60R17 and 225/55R18. Both are radial fitments, but they are not used interchangeably across every trim. Base and Premium models use 225/60R17, while Limited, Sport, and Touring models use 225/55R18.
The key step is matching the tire size to the exact sub-model and wheel diameter already on the vehicle. A Forester with 17-inch wheels needs the 17-inch fitment, and a Forester with 18-inch wheels needs the 18-inch fitment. Before choosing a tire, confirm the current wheel setup in case the vehicle has been changed from its original trim-level wheel package.
What size rim does a 2020 Subaru Trucks Forester use?
A 2020 Subaru Trucks Forester uses either a 17-inch or 18-inch rim, depending on sub-model. The 225/60R17 fitment is built for a 17-inch wheel, while the 225/55R18 fitment is built for an 18-inch wheel. Both sizes are modern radial applications.
Wheel diameter is the first fitment point to verify because the tire bead must match the wheel exactly. A 17-inch tire cannot be mounted on an 18-inch rim, and an 18-inch tire cannot be mounted on a 17-inch rim. If the Forester has aftermarket wheels, confirm both the actual wheel diameter and width before selecting tires.
Do all 2020 Subaru Trucks Forester sub-models use the same tire size?
No. The 2020 Subaru Trucks Forester splits between two tire sizes by sub-model. Base and Premium use 225/60R17, while Limited, Sport, and Touring use 225/55R18. The difference follows the wheel package, so trim identification matters before choosing a replacement tire.
That distinction is important because the two sizes use different rim diameters and should not be treated as interchangeable primary fitments. The quickest way to avoid ordering the wrong size is to confirm the sub-model and check the existing wheel size on the vehicle. That matters even more when a used Forester may have had wheels changed by a previous owner.
Choosing the Right Tire
What should I consider when choosing a 225/60R17 tire for a 2020 Subaru Trucks Forester?
Start by confirming that the Forester actually uses the 225/60R17 fitment, which applies to the Base and Premium sub-models. From there, compare the tire’s radial construction, load specification, rim-width suitability, sidewall style, and overall presentation. One available option in this size is a Travelstar UN106 with a Narrow Whitewall.
The right choice depends on whether the goal is a straightforward replacement or a more distinctive appearance. A whitewall treatment changes the look of a modern crossover more than many buyers expect, so it is worth deciding how original, understated, or custom the finished vehicle should appear. Wheel width and intended road use should be checked before final selection.
What sidewall styles are available for 2020 Subaru Trucks Forester tires?
Available sidewall style coverage for the 2020 Subaru Trucks Forester includes a Narrow Whitewall in 225/60R17. That makes sidewall appearance part of the buying decision rather than just the tire size itself. For some owners, that may be a subtle styling touch; for others, a plain modern look may remain the priority.
Sidewall style does not change the need to stay with the correct fitment for the sub-model and wheel diameter. It does, however, affect how the vehicle presents visually, especially on a clean street-driven Forester. Before choosing a decorative sidewall treatment, consider whether the vehicle is kept stock in appearance or carries other visual modifications that make the style feel intentional.
What brands offer tires for the 2020 Subaru Trucks Forester?
Travelstar is represented in the available 2020 Subaru Trucks Forester product selection, including a 225/60R17 radial option. Brand matters mainly as one part of the comparison alongside size, tire series, sidewall treatment, and specification details such as load capacity and wheel-width compatibility.
The most useful approach is to begin with the correct fitment for the vehicle, then compare what each brand offering brings within that size. A buyer looking at 225/60R17 should still verify the Forester is a Base or Premium model, or that it currently wears 17-inch wheels. Brand choice should follow fitment confirmation rather than replace it.
Restoration & Appearance
Which tire should I choose for a period-style 2020 Subaru Trucks Forester?
A 2020 Subaru Trucks Forester is a modern vehicle, so a period-style choice usually means staying with the proper radial size for the sub-model while selecting a tire with a distinctive presentation rather than pursuing antique or classic-era construction. In the available 225/60R17 fitment, a Narrow Whitewall creates a more stylized look than a plain sidewall.
The best starting point is still the vehicle’s correct wheel diameter and trim-level fitment. Once that is settled, appearance can guide the decision between a subtle factory-like presentation and a more personalized one. Buyers focused on preserving the Forester’s original showroom character should compare current wheel and tire appearance against period sales materials or marque-specific references.
Does correct tire fitment matter for a 2020 Subaru Trucks Forester restoration?
Yes. Even on a modern restoration or preservation project, correct tire fitment matters because the 2020 Subaru Trucks Forester uses different sizes across its sub-model range. The right tire size keeps the vehicle aligned with its intended wheel package and avoids mismatching a 17-inch application with an 18-inch one.
Appearance is only part of the equation. Proper fitment also affects how the finished vehicle sits visually and how naturally the wheel-and-tire package fills the openings. Anyone trying to return a Forester to a clean, trim-appropriate presentation should confirm the sub-model, wheel diameter, and tire size before making sidewall or brand decisions.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2020 Subaru Trucks Forester?
Yes. Modifications such as aftermarket wheels, suspension changes, lowering, spacers, or body alterations can change what fits a 2020 Subaru Trucks Forester even when the factory tire size is known. The original fitments are 225/60R17 and 225/55R18, but wheel width, offset, and available clearance can shift after modifications.
A Forester that has been changed from stock should be checked carefully before ordering replacement tires. Confirm the actual wheel diameter and width first, then inspect steering clearance, strut clearance, and fender room at normal ride height. That extra step helps prevent choosing a tire based only on trim-level fitment when the vehicle no longer carries its original setup.
What should I inspect before driving a 2020 Subaru Trucks Forester on new tires?
Before regular road use, inspect inflation pressure, bead seating, tread condition, valve stems, and visible sidewall condition. It is also smart to confirm the tire size matches the vehicle’s wheel diameter and sub-model fitment, since the 2020 Subaru Trucks Forester uses both 17-inch and 18-inch applications across the range.
A short, careful test drive is worthwhile after installation. Listen for rubbing, watch for vibration, and recheck pressure after the first miles. Any Forester with older suspension parts or non-stock wheels deserves a closer look at clearance in turns and over bumps. Catching those issues early is easier than troubleshooting uneven wear after the tires have already been used.
How often should tires on a 2020 Subaru Trucks Forester be inspected?
Tires on a 2020 Subaru Trucks Forester should be looked over regularly, not just when wear becomes obvious. Routine inspections should include pressure, tread depth, visible cuts, sidewall cracking, bulges, and signs of uneven wear. That matters whether the vehicle uses the 225/60R17 fitment or the 225/55R18 fitment.
Monthly visual checks are a sensible habit for a vehicle that sees normal road use, and a closer inspection before a longer trip is even better. A Forester that sits for stretches should also be checked for air loss and age-related condition changes. Keeping an eye on the tires helps preserve ride quality and can reveal alignment or suspension issues before they become larger problems.
