2024 Subaru Tire Fitment Guide

2024 Subaru vehicles use eleven different tire sizes across five models. The BRZ uses 215/45R17 and 215/40R18, the Impreza uses 205/55R16 and 225/40R18, the Legacy uses 225/55R17 and 225/50R18, the Outback uses 225/65R17 and 225/60R18, and the WRX uses 235/45R17, 245/40R18, and 245/35R19. Rim width guidance varies by size, with examples including 5.5 to 7.5 inches for 205/55R16, 7.5 to 9.0 inches for 225/40R18, and 8.0 to 9.5 inches for several WRX fitments.

The key takeaway is that year and make alone are not enough for 2024 Subaru tire selection. Subaru uses different wheel diameters and tire profiles across the lineup, so the first check should be your exact model and the wheel diameter currently on the car. Once that is confirmed, you can narrow the choice by brand, sidewall appearance, speed rating, and how you use the vehicle.

On a 2024 Subaru, 215/45R17 is a modern metric radial size. The 215 is the nominal section width in millimeters, 45 is the aspect ratio, meaning the sidewall height is 45 percent of the width, R means radial construction, and 17 is the wheel diameter in inches. On this Subaru application, that size belongs to the BRZ and fits a 17-inch wheel.

That code matters because every part of it affects fitment and driving character. A 215/45R17 cannot be swapped directly onto an 18-inch wheel, and it should not be confused with the BRZ's separate 215/40R18 option. If your 2024 Subaru BRZ has 17-inch wheels, this size keeps you in the correct diameter family before you compare among the available BFGoodrich choices.

No, 2024 Subaru models do not share one universal tire size. Each model uses its own size set, and some models have two wheel-diameter packages while the WRX has three. That means a BRZ, Impreza, Legacy, Outback, and WRX all occupy different fitment space even though they share the same model year.

That model-by-model variation affects more than appearance. The difference between a 225/65R17 Outback tire and a 245/35R19 WRX tire is substantial in wheel diameter, sidewall height, intended use, and product selection. If you are unsure which fitment your 2024 Subaru has, verify the sidewall on the current tires or the vehicle placard before spending time comparing brands.

Most 2024 Subaru tire sizes here are available as blackwall radials, which matches the contemporary look expected on modern Subaru cars and crossovers. One exception is 225/55R17 for the Legacy, which is also available in a wide whitewall version, and 225/65R17 for the Outback appears in an RBL style. Those sidewall treatments are size-specific rather than universal across the Subaru range.

For most owners, the choice is simple: blackwall is the natural visual fit for a 2024 Subaru. The wide whitewall option on the Legacy is more of a styling departure than an originality cue, so it tends to appeal to buyers building a custom look rather than those staying close to factory appearance. Confirm the exact size first, because sidewall style choices change from one Subaru model to another.

2024 Subaru tire coverage here comes from BFGoodrich, Nitto, Michelin, and M&H Racemaster, depending on size. BFGoodrich appears across most Subaru fitments, Nitto supports several 18- and 19-inch sport sizes, Michelin appears in 205/55R16, and M&H Racemaster appears in 245/40R18 for a specialty WRX application. Brand choice is tied closely to the exact size and vehicle mission.

That matters because not every brand is present in every Subaru size. A BRZ owner on 215/40R18 sees a different brand mix than a WRX owner on 245/40R18 or an Outback owner on 225/65R17. Once your size is confirmed, compare each brand's speed rating, rim-width compatibility, sidewall appearance, and product character instead of assuming the same options carry across the whole 2024 Subaru lineup.

For 2024 Subaru applications where both appear in the same size, BFGoodrich g-Force Comp-2 A/S and g-Force Sport Comp-2 share the same basic radial format but differ in exact series, load indexing in some sizes, and occasionally weight or published load detail. In 245/40R18, for example, the Comp-2 A/S carries a 97Y marking while the Sport Comp-2 carries a 93W marking. In several other Subaru sizes, both share similar rim-width ranges but still sit as distinct product lines within the BFGoodrich family.

The practical approach is to compare them size by size rather than assuming one answer fits every 2024 Subaru. Look at the exact sidewall marking, load index, speed rating, and any extra-load notation on the tire you are considering. That is especially important on WRX and larger-wheel applications, where the difference between W and Y ratings or standard and XL-style markings can affect how closely the replacement matches your intended use.

Rim width requirements for 2024 Subaru tires vary by size. Examples include 5.5 to 7.5 inches for 205/55R16, 7.0 to 8.0 inches for 215/45R17, 7.5 to 9.0 inches for 225/40R18 and 235/45R17, 6.0 to 8.0 inches for 225/50R18, 225/55R17, and 225/65R17, and 8.0 to 9.5 inches for 245/40R18 and 245/35R19. The 215/40R18 uses a 7.0 to 8.5 inch range, while the Legacy whitewall version of 225/55R17 broadens to 6.0 to 9.0 inches.

Those ranges are a reminder that wheel diameter alone is not the whole story. Two 18-inch Subaru tires can still call for different wheel widths, especially when comparing an Impreza fitment with a WRX fitment. Before choosing a replacement tire for a 2024 Subaru, confirm both the wheel diameter and the actual wheel width so the tire sits within the manufacturer's approved range.

Most 2024 Subaru tires here are modern radials and are treated as tubeless-type fitments, but tube marking is not uniform across every product string. The clearest example is 205/55R16, where Michelin marks the tire TL while the BFGoodrich alternatives do not carry the same sidewall notation in the size string. That makes tube status a product-by-product confirmation point rather than a blanket rule for every 2024 Subaru tire.

On a modern Subaru wheel, buyers generally start from the expectation of a tubeless radial, but it is still wise to verify the exact sidewall marking on the product you choose. If your wheels have been refinished, repaired, or replaced with aftermarket pieces, confirm that the wheel condition and valve hardware are appropriate for the tire being installed. That small check can prevent setup issues later.

A 2024 Subaru stored with its tires fitted should be kept out of direct sunlight and away from ozone-producing sources such as electric motors, battery chargers, and welders. Keep the storage area dry, maintain proper inflation, and move the vehicle periodically so the tires are not holding one static footprint for months at a time. Because every Subaru size here is radial, long idle periods are generally less troublesome than with older bias-ply tires, but flat spotting can still occur.

If the car will sit through a season, clean the tires, avoid petroleum-based dressings, and consider reducing sustained load by using stands only if done correctly and safely for the chassis. Enthusiast cars such as a BRZ or WRX, and even lower-use family cars like a second Legacy or Outback, benefit from a brief roll every few weeks. Good storage habits help preserve both ride quality and sidewall condition.

For a 2024 Subaru, tire age is often as important as tread depth, especially on lower-mileage enthusiast or seasonal-use vehicles. A practical rule is to begin close inspection and professional evaluation around five to seven years of age and to treat roughly ten years as a serious replacement threshold regardless of remaining tread. The DOT date code on the sidewall is the reference point for that timeline.

Mileage alone can be misleading because a WRX driven occasionally or a BRZ stored for winter may age out before the tread is worn. Heat cycles, sun exposure, storage conditions, and inflation history all affect service life. If your 2024 Subaru still wears tires that look visually healthy but are several years old, age should still be part of the replacement decision.

Tires on a 2024 Subaru should be inspected before every drive and again before any longer highway trip. Check for cuts, punctures, sidewall cracking, bulges, uneven wear, and pressure loss, and make sure the tread is wearing evenly across the contact patch. On performance-oriented sizes such as those used on the BRZ and WRX, shoulder wear can show up quickly if alignment or inflation is off.

A quick walkaround catches problems before they become roadside issues. Monthly pressure checks are wise even when the vehicle feels normal, and cars that sit for stretches should have their valve stems and spare tire checked as well. The closer the tire profile gets to low-profile 18- or 19-inch Subaru fitments, the more important it becomes to catch impact damage from potholes early.

Yes, the 2024 Subaru tire sizes here are highway-capable when the tire is in good condition, correctly inflated, and matched to the proper wheel. Most of the Subaru sizes carry W speed ratings, which correspond to a 168 mph ceiling, while the Outback's 225/65R17 carries an S rating with a 112 mph ceiling. In WRX sizes, some 245/40R18 and 245/35R19 products also reach Y rating, which is a 186+ mph ceiling.

In real use, normal interstate speeds sit far below those rating ceilings, so tire condition, inflation, alignment, and the vehicle's overall mechanical health matter more than headline speed capability. A 2024 Subaru used for commuting, road trips, or weekend driving can be fully comfortable at highway pace with the correct tire. The critical step is choosing the exact size and rating that belongs on your model and wheel package.

Inflation pressure for 2024 Subaru tires should start with the vehicle placard or owner's manual, because factory pressure recommendations are vehicle-specific even when two sizes look similar. Tire-side figures here show maximum load and pressure examples such as 1279 pounds at 50 psi for 215/40R18, 1819 pounds at 50 psi for one 225/55R17 application, and 2150 pounds at 65 psi for the 225/65R17 Outback tire. Those numbers are tire capacity limits, not automatic everyday pressure settings for every Subaru.

The safest approach is to use Subaru's recommended cold inflation pressure for your model, then confirm that the chosen tire is suitable for that operating range. Do not transfer a pressure figure from a WRX fitment to an Outback or from a 17-inch package to a 19-inch package. If you are changing tire series within the same size, keep the vehicle recommendation as the baseline and confirm the tire's own sidewall guidance.

Before a longer drive in a 2024 Subaru, inspect each tire for proper cold pressure, visible damage, irregular wear, punctures, and any sidewall bulging from prior impacts. Confirm tread depth is even, check that the spare is serviceable if your model carries one, and make sure the valve stems and caps are intact. On larger-wheel BRZ and WRX fitments, it is also smart to inspect the wheel lips for bends after pothole exposure.

Tires are only one part of the trip-prep picture, but they are the part in constant contact with the road. A sound set of correctly inflated tires helps the ABS, stability control, and all-wheel-drive system work as intended on models that use them. Pair the tire check with a quick review of brakes, fluids, and alignment feel so your 2024 Subaru starts the trip on solid footing.
