The 2020 Subaru Outback sits at the intersection of wagon practicality and light-duty adventure, blending everyday road comfort with the higher ride height and utility that have long defined the model. For buyers researching this exact Outback, tire selection starts with identifying trim, because this year uses two primary radial sizes: 225/65R17 and 225/60R18. That means the key decision is less about vintage construction choices and more about matching the correct wheel diameter and sub-model. Once size is confirmed, the focus shifts to road use, tread character, and whether the tire suits a stock daily-driven setup or a more rugged, all-terrain look.
Which Tire Size Is Right for The 2020 Subaru Outback
The 2020 Subaru Outback uses two primary tire sizes, and the correct one depends on the specific 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 actual rim diameter is the first step before comparing tire options or replacement styles.
225/65R17 is a metric radial size in which 225 is the section width in millimeters, 65 is the aspect ratio, R indicates radial construction, and 17 is the wheel diameter in inches. On the 2020 Subaru Outback, this size is part of the stock-style fitment used on certain trims with 17-inch wheels. Available product choice in this size includes an all-terrain-style BFGoodrich option with an RBL sidewall and the All Terrain TA KO2 series. This size is the one to evaluate when the Outback has the 17-inch wheel package and the goal is to keep the proper wheel diameter while choosing the right tread character.
225/60R18 follows the same modern metric radial format, with a 225-millimeter section width, a 60-series profile, radial construction, and an 18-inch rim diameter. For the 2020 Subaru Outback, this size applies to trims equipped with the 18-inch wheel setup rather than the 17-inch package. Even though its section width matches the 17-inch size, the wheel diameter is different, so it should be selected only after the vehicle's actual wheels are confirmed. This is the correct path for Outback trims that came with 18-inch rims and need a replacement in the original sizing format.
Tire fitment for the 2020 Subaru Outback varies by sub-model, and the split is tied directly to wheel diameter. Checking the exact trim matters because some Outbacks use 17-inch wheels with 225/65R17 tires, while others use 18-inch wheels with 225/60R18 tires.

2020 Subaru Outback Base
The 2020 Subaru Outback Base uses the 225/65R17 radial tire size on a 17-inch wheel setup. Tire selection here starts with retaining that 17-inch fitment and then choosing a replacement that matches how the vehicle is actually used on pavement, gravel, or mixed driving.
The 2020 Subaru Outback Limited uses the 225/60R18 radial size, which places it on the 18-inch wheel package rather than the 17-inch setup. That makes wheel-diameter confirmation especially important before comparing replacement tires or considering any change in tread style.
The 2020 Subaru Outback Limited XT uses 225/60R18 radial tires. For this sub-model, the practical tire decision centers on keeping the 18-inch sizing correct and selecting a tire that suits the vehicle's current wheels, ride expectations, and intended driving conditions.
The 2020 Subaru Outback Onyx Edition XT uses the 225/60R18 radial tire size. That means any replacement search should begin by matching the 18-inch wheel fitment first, then comparing tire choices based on tread design, use case, and overall road manners.
The 2020 Subaru Outback Premium uses 225/65R17 radial tires. Buyers working with this trim should stay focused on the 17-inch wheel setup and then decide whether the replacement tire should emphasize standard road use or a more rugged all-terrain presentation.
The 2020 Subaru Outback Touring uses the 225/60R18 radial size. That keeps tire selection tied to the 18-inch wheel package, so the important next step is choosing a tire that matches the vehicle's wheel dimensions and the way the Outback is driven.
The 2020 Subaru Outback Touring XT also uses 225/60R18 radial tires. Replacement planning should stay centered on the 18-inch fitment, with attention given to maintaining proper clearance and choosing a tire style that fits the vehicle's actual road and weather use.
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.

These 2020 Subaru Outback tire FAQs focus on the two factory-size fitment paths, the trim-to-wheel-diameter split, available product choice in 225/65R17, and the fitment checks that matter before regular driving or longer trips.
Tire Size & Fitment
What tire size fits a 2020 Subaru Outback?
The 2020 Subaru Outback uses two tire sizes: 225/65R17 and 225/60R18. Both are radial metric sizes, and the correct choice depends on the sub-model and wheel package. Base and Premium models use 225/65R17, while Limited, Limited XT, Onyx Edition XT, Touring, and Touring XT models use 225/60R18.
The most important step is confirming the actual wheel diameter on the vehicle before ordering tires. A used or modified Outback may no longer have its original wheels, so checking the tire sidewall and the wheel itself helps prevent mixing a 17-inch tire search with an 18-inch wheel setup.
What size rim does a 2020 Subaru Outback use?
A 2020 Subaru Outback uses either a 17-inch or 18-inch rim, depending on trim. The 225/65R17 tire size pairs with a 17-inch wheel, while the 225/60R18 tire size pairs with an 18-inch wheel. Both sizes keep a similar overall tire height, but they are built for different wheel diameters.
Wheel diameter is not something to estimate by appearance alone, especially on vehicles that may have had wheels swapped. Reading the existing tire size, measuring the wheel properly, and confirming the trim helps keep replacement selection on track and avoids choosing a tire that cannot be mounted on the current wheels.
Why does the 2020 Subaru Outback have more than one tire size?
The 2020 Subaru Outback has more than one tire size because different sub-models use different wheel packages. Some trims were equipped with 17-inch wheels and 225/65R17 tires, while others use 18-inch wheels and 225/60R18 tires. Both are primary fitments for this model year, but they are not interchangeable without matching the wheel.
That means the correct tire is tied to the exact trim and the actual wheel currently on the vehicle. If the Outback has changed hands or received aftermarket wheels, checking what is mounted now is more useful than assuming the present setup still matches the original trim-based fitment.
Choosing the Right Tire
What should I consider when choosing a 225/65R17 tire for a 2020 Subaru Outback?
Start by confirming that the Outback actually uses the 17-inch wheel package, since 225/65R17 applies to specific trims rather than every 2020 Outback. After size is confirmed, compare the tire's intended use, construction, load capacity, sidewall style, and rim-width compatibility. In this size, an available choice is the BFGoodrich All Terrain TA KO2 radial with an RBL sidewall.
Selection should reflect how the vehicle is driven most of the time. A more aggressive all-terrain tire may suit gravel roads, trail access, or rougher conditions, but wheel width, clearance, and ride expectations still matter. Matching the tire to both the 17-inch wheel and the Outback's real-world use usually leads to the best result.
What sidewall styles are available for 2020 Subaru Outback tires?
For the currently available 225/65R17 product fitment on the 2020 Subaru Outback, the sidewall style is RBL. That gives the tire a more traditional black sidewall presentation rather than raised white letters, whitewall styling, or a stripe treatment. Sidewall style affects appearance first, but it can also shape the overall character the vehicle projects.
Appearance matters more than many buyers expect, especially on a crossover that may be used as both a daily driver and an outdoor-use vehicle. Once the correct size is locked in, sidewall treatment becomes part of the selection process, along with tread pattern and intended use, rather than a separate fitment question.
What brands offer tires for the 2020 Subaru Outback?
The available product choice for the 2020 Subaru Outback in 225/65R17 includes BFGoodrich. That option appears in the All Terrain TA KO2 series and gives buyers a concrete product to compare by load capacity, rim-width range, construction, and tread style rather than by brand name alone.
Brand is only one part of the decision. The better approach is to make sure the tire matches the Outback's correct size, wheel diameter, and expected use, then compare details such as sidewall styling, weight, and all-terrain versus road-focused character. That keeps the purchase centered on fitment and function rather than name recognition.
Restoration & Appearance
Which tire should I choose for a period-style 2020 Subaru Outback?
A period-style approach on a 2020 Subaru Outback usually means staying with the correct original sizing format for the trim and wheel package, either 225/65R17 or 225/60R18. Since this is a modern Outback, the appearance question is less about vintage construction and more about keeping the right proportions, wheel diameter, and overall visual balance.
The practical decision is whether the vehicle should retain a stock-style look or lean toward a more rugged presentation. An all-terrain-style tire in 225/65R17 changes the Outback's visual character without changing the basic size format, but the trim, wheel package, and current setup should still be confirmed before making that move.
Does correct tire fitment matter for a 2020 Subaru Outback restoration?
Correct tire fitment matters on a 2020 Subaru Outback because the right size preserves the intended relationship between the tire, wheel, and body. Using the proper 225/65R17 or 225/60R18 size for the trim helps maintain the original wheel-diameter presentation and avoids an appearance that looks obviously off for the vehicle.
That matters even more when the goal is a clean stock-style refresh rather than a custom build. Before settling on a replacement tire, confirm the trim, the wheel diameter, and the current wheel setup on the vehicle, especially if it has had previous owner changes that may no longer match original fitment.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2020 Subaru Outback?
Modifications can affect tire fitment on a 2020 Subaru Outback, especially if the vehicle has aftermarket wheels, altered suspension height, spacers, or body changes. Even when the tire size itself is correct, changes in wheel width, offset, or ride height can alter clearance at the strut, fender, or steering range.
That is why the current setup matters as much as the original trim fitment. A buyer should verify wheel diameter first, then check actual wheel dimensions and inspect clearance around the tire at full steering lock and through suspension travel before assuming the present configuration behaves like a stock Outback.
What should I inspect before driving a 2020 Subaru Outback on new tires?
Before driving a 2020 Subaru Outback on new tires, inspect the wheel diameter, confirm the installed tire size, and make sure inflation pressure is set correctly for the tire being used. It is also wise to check for any rubbing at the inner wheelhouse or suspension and to verify that lug hardware and wheel seating are correct.
A short, careful road test is the next step. Listen for contact noises, pay attention to steering feel, and recheck pressure after the first drive. On an Outback that has seen wheel swaps, alignment issues, or suspension wear, those basic checks can catch fitment and drivability problems early.
What should I check before a longer drive in a 2020 Subaru Outback?
Before a longer drive in a 2020 Subaru Outback, check tire pressure, tread condition, sidewall condition, and any signs of cuts, bulges, or slow air loss. The tire size should match the wheel package actually on the vehicle, and the tires should be inspected for uneven wear that could point to alignment or suspension issues.
Longer highway trips put more heat and sustained load into the tires than short local driving. It helps to confirm that the spare and roadside tools are present, then look over the wheels and tires again after the first fuel stop. That routine is especially useful on vehicles used in mixed road and trail conditions.
