The 2019 Subaru Outback sits in the modern crossover wagon space where everyday comfort, all-weather confidence, and light adventure use all matter. Buyers often choose this generation for its practical road manners and versatile stance, which makes correct tire sizing especially important to how the vehicle looks and drives. This Outback uses one of two primary radial sizes, 225/65R17 or 225/60R18, depending on the sub-model and wheel package. That means the real tire decision starts with confirming the exact trim and rim diameter, then comparing the available tire style and intended use. For a road-going Outback, wheel setup, clearance, and overall use should guide the final choice.
Which Tire Size Is Right for The 2019 Subaru Outback
The 2019 Subaru Outback uses two primary tire sizes, and the correct one depends on the specific sub-model and wheel diameter. Both are metric radial sizes, but one fits 17-inch wheels and the other fits 18-inch wheels, so the first step is confirming the exact trim level and checking the wheels currently on the vehicle before selecting a tire.
225/65R17 is a metric radial size in which 225 is the section width in millimeters, 65 is the aspect ratio, R identifies radial construction, and 17 is the wheel diameter in inches. On the 2019 Subaru Outback, this size is used on specific sub-models with 17-inch wheels and keeps the fitment tied to that wheel package. Product choice in this size can also involve details such as sidewall treatment and intended tire character, including the BFGoodrich All-Terrain T/A KO2 with an RBL sidewall. This is the size to evaluate when the vehicle has the correct 17-inch wheel setup and a use case that may extend beyond ordinary pavement driving.
Fit(s): 2.5i Limited, 2.5i Touring, 3.6R Limited, and 3.6R Touring
Construction: Radial|Rim: 18 in
225/60R18 follows the same metric radial system, with a 225-millimeter section width, a 60-series profile, radial construction, and an 18-inch rim diameter. On the 2019 Subaru Outback, this size applies to sub-models equipped with 18-inch wheels, so it should not be chosen simply because the overall dimensions appear close to the 17-inch option. The lower profile changes the tire's relationship to the wheel package even though both sizes are modern radials. This is the fitment to confirm when the Outback carries its correct 18-inch wheels or when wheel changes have already been made and need to be verified carefully.
Sub-model fitment matters on the 2019 Subaru Outback because tire size changes with the trim and wheel package. Some versions use 17-inch radial fitment, while others use 18-inch radial fitment, so confirming the exact sub-model is the quickest way to narrow the correct size.

2019 Subaru Outback 2.5i
The 2019 Subaru Outback 2.5i uses the 225/65R17 radial size on a 17-inch wheel package. Tire selection here begins with staying with that wheel diameter, then comparing the available tire style and intended road or light-trail use.
The 2019 Subaru Outback 2.5i Limited uses the 225/60R18 radial size. That makes wheel confirmation especially important, since the correct tire choice depends on retaining the 18-inch setup or carefully verifying any wheel change already made.
The 2019 Subaru Outback 2.5i Premium uses the 225/65R17 radial size. Buyers looking at replacement tires should keep the focus on correct 17-inch fitment first, then compare tire construction details, sidewall presentation, and intended use.
The 2019 Subaru Outback 2.5i Touring uses the 225/60R18 radial size. For this sub-model, the main selection step is confirming the 18-inch wheel package before evaluating tire type, profile, and any differences among available products.
The 2019 Subaru Outback 3.6R Limited uses the 225/60R18 radial size. Tire shopping for this trim should stay centered on the correct 18-inch fitment, with added attention to wheel compatibility if the vehicle has been modified.
The 2019 Subaru Outback 3.6R Touring uses the 225/60R18 radial size. That keeps the decision straightforward as long as the vehicle still has the correct wheel diameter, after which the focus shifts to tire type and real-world driving 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.

Common 2019 Subaru Outback tire questions usually come down to trim-specific sizing, 17-inch versus 18-inch wheel fitment, and how to choose a tire that matches the vehicle's actual use. The answers below focus on correct size selection, product choice, and practical checks before road use.
Tire Size & Fitment
What tire size fits a 2019 Subaru Outback?
The 2019 Subaru Outback uses either 225/65R17 or 225/60R18, depending on the sub-model and wheel package. Both are radial tire sizes, but they are not interchangeable without matching the correct rim diameter first.
The important next step is confirming the exact trim level and checking the wheels currently on the vehicle. A 17-inch Outback setup needs the 225/65R17 fitment, while an 18-inch setup needs 225/60R18, and any aftermarket wheel change should be verified for diameter, width, and clearance before choosing a replacement tire.
What size rim does a 2019 Subaru Outback use?
A 2019 Subaru Outback uses either a 17-inch or 18-inch rim, depending on the sub-model. The 225/65R17 tire size pairs with a 17-inch rim, and the 225/60R18 tire size pairs with an 18-inch rim.
Rim diameter is the first fitment check because the tire bead must match the wheel exactly. Even though the two Outback tire sizes are close in overall dimensions, the vehicle still needs the correct wheel diameter, and any owner working with replacement wheels should also confirm width and clearance before mounting tires.
Do all 2019 Subaru Outback sub-models use the same tire size?
No, 2019 Subaru Outback sub-models do not all use the same tire size. The 2.5i and 2.5i Premium use 225/65R17, while the 2.5i Limited, 2.5i Touring, 3.6R Limited, and 3.6R Touring use 225/60R18.
That difference makes trim identification more than a minor detail. Checking the badge alone is helpful, but the actual wheel diameter on the vehicle matters just as much, especially if wheels have been changed, because selecting the wrong tire size can stop the tire from matching the wheel even before clearance is considered.
Choosing the Right Tire
What should I consider when choosing a 225/65R17 tire for a 2019 Subaru Outback?
Start with the basics: the vehicle must be one of the 2019 Subaru Outback sub-models that uses 225/65R17, and the wheel must be a 17-inch rim. From there, the decision shifts to the tire's intended character, sidewall style, construction details, and whether the vehicle is used mainly on pavement or in more rugged conditions.
The available 225/65R17 product includes a BFGoodrich All-Terrain T/A KO2 with an RBL sidewall, a 17-inch rim fitment, and a 6.0 to 8.0 inch rim-width range. That makes it important to compare the actual wheel width on the vehicle and decide whether an all-terrain-style tire matches how the Outback is driven.
What sidewall styles are available for 2019 Subaru Outback tires?
The available 225/65R17 product for the 2019 Subaru Outback uses an RBL sidewall style. That gives this fitment a more utility-oriented presentation rather than a classic whitewall or raised-letter appearance.
Sidewall style affects the look of the vehicle, but it should still be considered after the correct size, wheel diameter, and intended use are confirmed. On a newer Outback, appearance usually works alongside practical factors such as tire type, wheel compatibility, and whether the vehicle spends most of its time on-road, in winter conditions, or on rougher surfaces.
What brands offer tires for the 2019 Subaru Outback?
BFGoodrich is represented in the available product selection for the 2019 Subaru Outback, specifically in 225/65R17. The tire series available there is the All-Terrain T/A KO2, which places the current choice in a more rugged radial category.
Brand is only one part of the decision. It still helps to compare the exact size, wheel fitment, sidewall style, load figure, and intended use of the tire, since an Outback driven mainly on pavement may call for a different selection approach than one that regularly sees gravel roads, trail access routes, or heavier cargo duty.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2019 Subaru Outback?
Yes, modifications can affect tire fitment on a 2019 Subaru Outback. Wheel changes, suspension alterations, ride-height changes, and body or fender modifications can all change whether the original 225/65R17 or 225/60R18 size remains appropriate for the vehicle's current setup.
A modified Outback should be checked for wheel diameter, wheel width, and clearance at full steering lock and suspension movement before a new tire is chosen. Even a tire size that belongs on another Outback sub-model still needs to match the actual wheels on the vehicle, and close dimensional similarity does not make two sizes automatically interchangeable.
What should I inspect before driving a 2019 Subaru Outback on new tires?
Before driving a 2019 Subaru Outback on new tires, inspect the wheel diameter, confirm the tire size matches the trim and wheel package, and make sure the tires are mounted and inflated correctly. It is also worth checking for any visible clearance issues around the fenders, struts, and steering components.
A short initial road test should include listening for rubbing, feeling for vibration, and rechecking air pressure once the tires have settled. On any Outback that has seen wheel swaps, suspension work, or long periods of storage, it also helps to inspect alignment condition and general suspension wear so the new tires are not compromised early.
How often should tires on a 2019 Subaru Outback be inspected?
Tires on a 2019 Subaru Outback should be inspected regularly, not just when tread looks worn. Pressure, tread condition, sidewall cuts, cracking, bulges, and uneven wear all deserve attention, especially on a vehicle that sees changing weather, rough roads, or periods of lower use.
A quick visual check before longer drives is a sensible habit, and a closer inspection should follow any impact, off-pavement outing, or noticeable change in ride feel. Owners should also keep an eye on slow air loss and irregular wear patterns, since those can point to wheel damage, alignment issues, or suspension problems rather than the tire alone.
