The 2023 Subaru Outback sits in the modern crossover wagon space where everyday road comfort, light adventure duty, and year-round practicality all matter. Buyers usually arrive here already knowing that Outback trim level has a direct effect on tire fitment, because wheel diameter changes across the lineup. This model uses two primary radial sizes, 225/65R17 and 225/60R18, tied to different sub-models and 17-inch or 18-inch wheels. That makes the real decision less about vintage-style construction choices and more about confirming the exact trim, wheel setup, and intended use. For owners replacing worn tires or evaluating a tougher all-terrain option, accurate sub-model fitment comes first.
Which Tire Size Is Right for The 2023 Subaru Outback
The 2023 Subaru Outback uses two primary tire sizes, and the right 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. Before choosing a tire, confirm the exact trim and make sure the vehicle still has its correct wheel size, especially if wheels have been changed since new.
A 225/65R17 tire is a metric radial size with a 225-millimeter nominal section width, a 65-series aspect ratio, radial construction, and a 17-inch rim diameter. On the 2023 Subaru Outback, this size serves trims that use the 17-inch wheel package, so it is important to keep it matched to the proper wheel diameter rather than treating it as interchangeable with the 18-inch setup. Available product choice in this size can also reflect the vehicle's intended use, including more trail-oriented all-terrain construction. It is the size to evaluate when ground-covering versatility and correct 17-inch wheel fitment are the priority.
A 225/60R18 tire uses the same 225-millimeter nominal section width as the 17-inch option, but it pairs that width with a 60-series aspect ratio and an 18-inch rim diameter. For the 2023 Subaru Outback, this size belongs to trims equipped with 18-inch wheels, so wheel confirmation is the first step before comparing tires. The practical difference is not just the size code itself, but the fact that it belongs to a different wheel package within the Outback lineup. This is the fitment to focus on when your sub-model is built around the 18-inch setup.
Tire fitment varies across the 2023 Subaru Outback range, so the trim level matters before anything else. Some sub-models use 225/65R17 on 17-inch wheels, while others use 225/60R18 on 18-inch wheels, making wheel and sub-model confirmation the key first step.

2023 Subaru Outback Base
The 2023 Subaru Outback Base uses the 225/65R17 radial size. That keeps tire selection centered on the 17-inch wheel package, so replacement shopping starts with confirming the vehicle still carries its original wheel diameter.
The 2023 Subaru Outback Limited uses the 225/60R18 radial size. Tire choice here depends on staying with the 18-inch wheel setup and comparing options intended for that trim's wheel diameter.
The 2023 Subaru Outback Limited XT uses the 225/60R18 radial size. That makes 18-inch wheel confirmation the first priority before comparing replacement tires or checking for any changes made by a previous owner.
The 2023 Subaru Outback Onyx Edition uses the 225/60R18 radial size. Tire selection should stay focused on the 18-inch fitment, with attention to the actual wheel setup if the vehicle has been modified.
The 2023 Subaru Outback Onyx Edition XT uses the 225/60R18 radial size. Buyers should treat that as an 18-inch wheel fitment question first, then compare tire choices within the correct size.
The 2023 Subaru Outback Premium uses the 225/65R17 radial size. That places tire selection within the 17-inch wheel package, so correct replacement starts with verifying wheel diameter and overall setup.
The 2023 Subaru Outback Touring uses the 225/60R18 radial size. For this trim, proper tire selection begins with the 18-inch wheel package and any fitment changes that may have happened after delivery.
The 2023 Subaru Outback Touring XT uses the 225/60R18 radial size. Tire shopping should remain tied to the 18-inch wheel fitment rather than assuming every 2023 Outback uses the same size.
The 2023 Subaru Outback Wilderness uses the 225/65R17 radial size. That makes the 17-inch setup the correct starting point, especially for owners comparing more rugged tire options within the proper size.
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)

Tire Size & Fitment
What tire size fits a 2023 Subaru Outback?
The 2023 Subaru Outback uses either 225/65R17 or 225/60R18, depending on the sub-model. Base, Premium, and Wilderness trims use 225/65R17, while Limited, Limited XT, Onyx Edition, Onyx Edition XT, Touring, and Touring XT use 225/60R18.
The practical difference is wheel diameter. A 17-inch Outback setup takes the 225/65R17 size, and an 18-inch setup takes 225/60R18. Trim level is the quickest guide, but the wheel itself should still be checked, especially if the vehicle has aftermarket wheels, a second wheel set, or any prior fitment changes.
What size rim does a 2023 Subaru Outback use?
A 2023 Subaru Outback uses either a 17-inch or 18-inch rim, depending on sub-model. The 225/65R17 tire is built for a 17-inch wheel, and the 225/60R18 tire is built for an 18-inch wheel.
That makes rim diameter the first thing to confirm before replacing tires. Two Outbacks from the same model year can require different tires simply because they carry different wheel packages. A quick check of the sidewall size or the wheel itself helps prevent choosing an otherwise correct-looking tire that does not match the rim.
Do all 2023 Subaru Outback sub-models use the same tire size?
No. The 2023 Subaru Outback lineup is split between two tire sizes. Base, Premium, and Wilderness use 225/65R17, while Limited, Limited XT, Onyx Edition, Onyx Edition XT, Touring, and Touring XT use 225/60R18.
That split means tire shopping starts with identifying the exact sub-model, not just the year and model name. It also means two Outbacks parked side by side may need different replacements. If the vehicle has been modified, verify the actual mounted wheel diameter and current tire size before treating trim-level fitment as the final answer.
Choosing the Right Tire
What should I consider when choosing a 225/65R17 tire for a 2023 Subaru Outback?
Start with the correct size, radial construction, and wheel compatibility. On the 2023 Subaru Outback, 225/65R17 belongs to the 17-inch setup used on Base, Premium, and Wilderness trims, so the tire needs to match that wheel diameter before anything else is compared.
After size confirmation, look at how the tire is built for use. The available BFGoodrich All Terrain T/A KO2 in this size uses an RBL sidewall and a 6.0- to 8.0-inch rim-width range, which makes it especially relevant for owners who want a more rugged presentation or all-terrain character. Intended driving use should guide the final choice.
What brands offer tires for the 2023 Subaru Outback?
For the fitments shown here, BFGoodrich is available in 225/65R17 for the 2023 Subaru Outback. That option appears as an All Terrain T/A KO2 radial, aimed at buyers using the 17-inch wheel package on Base, Premium, or Wilderness trims.
Brand matters most after the correct trim and wheel diameter have been confirmed. A 225/65R17 option does not answer the needs of an Outback that uses 225/60R18, and the reverse is also true. Once fitment is verified, compare how the tire's construction, sidewall treatment, and intended use line up with the way the vehicle is driven.
What tire series are available for the 2023 Subaru Outback?
The available tire series shown for the 2023 Subaru Outback is the BFGoodrich All Terrain T/A KO2 in 225/65R17. It is a radial tire offered for Outback trims that use the 17-inch wheel setup.
A tire series helps signal the character of the product, not just its dimensions. In this case, the All Terrain T/A KO2 points toward a more rugged use profile than a standard highway-style replacement. That makes it worth comparing against your actual driving needs, wheel setup, and whether the Outback spends more time on pavement or mixed surfaces.
Restoration & Appearance
Does correct tire fitment matter for a 2023 Subaru Outback restoration?
Yes. Even on a modern vehicle like the 2023 Subaru Outback, correct tire fitment still matters if the goal is to preserve the proper look and stance of a specific trim. The main fitment distinction is between 225/65R17 on 17-inch wheels and 225/60R18 on 18-inch wheels.
Choosing the wrong wheel diameter changes more than appearance because it also changes what size tire the vehicle can accept. A clean, trim-appropriate presentation starts with matching the tire to the correct wheel package. If originality matters closely, compare the vehicle against its trim-level equipment and current wheel setup before choosing replacements.
How does tire construction affect the appearance of a restored 2023 Subaru Outback?
The 2023 Subaru Outback uses radial tires, so construction choice is not a bias-ply-versus-radial restoration question here. Appearance is shaped more by using the correct modern metric size for the trim and by details such as sidewall treatment and the overall character of the tire series.
A more rugged all-terrain design can give the Outback a tougher visual stance, while the wrong wheel diameter or size can make the vehicle look obviously out of place. For a clean, restoration-minded result, keep the trim's wheel package in focus first and then compare sidewall and tread presentation within the correct size.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2023 Subaru Outback?
Yes. Wheel changes, suspension lifts or lowering, and aftermarket tire substitutions can all affect tire fitment on a 2023 Subaru Outback. That matters because this model already uses two different wheel diameters from the factory, so any change from stock can complicate replacement selection.
The key checks are actual wheel diameter, wheel width, current tire size, and clearance at the fenders and steering components. An Outback with non-stock wheels should not be treated as a standard trim-level fitment without verification. A quick inspection before ordering tires helps avoid choosing a size that matches the trim on paper but not the vehicle as it sits.
What should I inspect before driving a 2023 Subaru Outback on new tires?
Before regular road use, inspect tire pressure, bead seating, lug torque, and the clearance around the wheel well and suspension. It is also smart to confirm that all four tires match in size and construction, especially on a vehicle like the 2023 Subaru Outback where trim-level wheel packages differ.
A short local drive followed by a recheck can catch rubbing, vibration, or pressure loss early. Owners should also look at tread condition on any tire being reused, along with sidewall cuts, bulges, or cracking. Those basic checks matter whether the Outback is used for commuting, travel, or occasional unpaved-road driving.
How often should tires on a 2023 Subaru Outback be inspected?
Tires on a 2023 Subaru Outback should be inspected regularly rather than only when wear becomes obvious. Monthly pressure checks and routine visual inspections for tread wear, cuts, bulges, and sidewall damage are a sensible baseline, especially if the vehicle sees changing weather or mixed pavement and trail use.
Inspection matters even more after pothole impacts, off-pavement driving, or wheel changes. Catching uneven wear early can reveal alignment or suspension issues before they become expensive tire problems. It also helps confirm that the vehicle is still running the correct 17-inch or 18-inch fitment for its wheel package and current setup.
