2019 Subaru Tire Fitment Guide

2019 Subaru vehicles use 12 different sizes across six models. BRZ uses 215/45R17; Impreza uses 205/55R16, 205/50R17, or 225/40R18; Legacy uses 225/55R17 or 225/50R18; Outback uses 225/65R17 or 225/60R18; WRX uses 235/45R17 or 245/40R18; and WRX STI uses 245/35R19 and 265/35R19. Rim diameters span 16, 17, 18, and 19 inches, and rim-width suitability varies by size, from 5.5-7.5 inches on some Impreza fitments to 9-10.5 inches on 265/35R19 WRX STI applications.

That spread means year and make alone are not enough for an accurate tire choice. The first check should be the model, followed by the wheel diameter already on the car, since many Subaru owners run alternate factory wheel packages or replacement wheels. Once the model and wheel size are confirmed, the remaining decision is usually which brand, sidewall style, or performance-oriented product best suits how the car is used.

On a 2019 Subaru, 215/45R17 is a metric radial size. The 215 is the nominal section width in millimeters, 45 is the aspect ratio, R identifies radial construction, and 17 is the wheel diameter in inches. Within the 2019 Subaru range, that size belongs to the BRZ and mounts on a 17-inch wheel, with products offered in Blackwall form and W speed ratings to 112 mph.

Understanding that code matters because a 17-inch Subaru tire is not interchangeable just because the wheel diameter matches. A BRZ’s 215/45R17 differs substantially in width and profile from a WRX’s 235/45R17 or a Legacy’s 225/55R17. If the sidewall on the car reads 215/45R17, stay with that size unless you are deliberately changing wheel-and-tire fitment with the guidance of a Subaru specialist.

No. 2019 Subaru models do not share a common tire size across the full lineup. The BRZ, Impreza, Legacy, Outback, WRX, and WRX STI each have their own fitment patterns, and some models use more than one size depending on wheel package. The WRX STI is the most specialized of the group, using 19-inch sizes in both 245/35R19 and 265/35R19, while the Impreza spans three different wheel diameters from 16 to 18 inches.

That difference affects much more than appearance. Overall tire width, sidewall height, and wheel diameter all change from model to model, so selecting by year and make alone can easily put you into the wrong fitment family. If you are unsure, confirm the model badge, inspect the current tire sidewall, and compare the wheel diameter before choosing a replacement.

Most 2019 Subaru sizes are available in Blackwall form, which is the dominant sidewall style across the BRZ, Impreza, Legacy, WRX, and WRX STI applications. A few sizes add variety: 205/50R17 for the Impreza and 225/55R17 for the Legacy can be found with Wide Whitewall styling, while 225/65R17 for the Outback appears with an RBL sidewall. Those sidewall differences exist within specific sizes rather than across the entire Subaru range.

For a 2019 Subaru, Blackwall is generally the most natural visual match for the era and the vehicles’ original character. Whitewall options are more of a styling choice than an authenticity requirement on a modern Subaru, while the RBL all-terrain look can make sense on an Outback with a more rugged visual theme. Start with the correct size, then decide whether you want the tire to blend in or make more of a statement.

2019 Subaru sizes are covered by BFGoodrich across most of the range, with additional coverage from Michelin, American Classic, Nitto, and M&H Racemaster in certain applications. BFGoodrich appears in nearly every active size group, Michelin appears in 205/55R16, American Classic appears in 205/50R17, Nitto appears in several 17-, 18-, and 19-inch performance sizes, and M&H Racemaster appears in 245/40R18. Brand availability depends on the exact tire size rather than the Subaru badge alone.

That means the brand conversation should happen after the fitment conversation. A BRZ owner choosing among BFGoodrich options is solving a different problem than a WRX owner comparing BFGoodrich, Nitto, and a drag-oriented M&H tire in 245/40R18. Once the correct size is confirmed, the useful comparison becomes sidewall style, speed rating, and the overall character of the tire within that size.

On several 2019 Subaru sizes, both BFGoodrich g-Force Comp-2 A/S and BFGoodrich g-Force Sport Comp-2 are offered with the same wheel-diameter fitment and similar rim-width ranges, but they are separate series with their own sidewall markings and in some cases slightly different load details. For example, in 245/40R18 both fit 18-inch wheels and 8.0-9.5-inch rim widths, while in 225/40R18 both fit 18-inch wheels and 7.5-9.0-inch rim widths. Both typically use a Blackwall appearance and performance-oriented radial construction.

The practical takeaway is to compare them at the exact size level rather than assuming one Subaru fitment behaves the same as another. When two series share your size, look closely at the sidewall information, load figure where stated, and the role you want the tire to play on the car. That is especially helpful on WRX, Legacy, and Impreza applications where multiple BFGoodrich series overlap.

Rim width varies by size across the 2019 Subaru lineup. 205/55R16 and 205/50R17 work with 5.5-7.5-inch rims; 215/45R17 works with 7.0-8.0-inch rims; 225/40R18 works with 7.5-9.0-inch rims; 225/55R17 and 225/50R18 commonly fit 6.0-8.0-inch rims, with one 225/55R17 whitewall extending to 9.0 inches; 225/65R17 fits 6.0-8.0-inch rims; 235/45R17 fits 7.5-9.0-inch rims; 245/40R18 fits around 8.0-9.5 inches, with one drag tire centered at 8.5; and 265/35R19 reaches 9.0-10.5 inches.

Those numbers are one of the easiest ways to avoid a mismatch when a car has aftermarket wheels. Even if the tire size on the sidewall looks right, the wheel still needs to fall within the approved width range for that specific tire. Confirm the wheel width before ordering, especially on WRX and WRX STI fitments where lower-profile tires and wider wheels leave less room for error.

2019 Subaru tires are fundamentally modern radial fitments, and tube-type markings are not a normal part of these applications. Some sizes show explicit tubeless marking on the sidewall, such as the Michelin 205/55R16 with a TL designation, while many other products simply present as standard modern radials without a separate tube notation. Across this year and make, there is no pattern suggesting inner tubes as a routine requirement.

The important step is to match the tire to the wheel that is actually on the car. Original and replacement Subaru wheels from this era are generally intended for tubeless radial use, but the exact sidewall marking on the product should still be checked before installation. If the car has unusual aftermarket wheels or a specialty motorsports setup, confirm compatibility with the wheel manufacturer as well.

No, because 2019 Subaru fitments span multiple wheel diameters and widths. The model range uses 16-, 17-, 18-, and 19-inch tire sizes, so an original wheel from one Subaru model usually will not accept every other Subaru size from the same year. Even among sizes sharing a diameter, approved rim widths differ, such as 205/50R17 at 5.5-7.5 inches versus 235/45R17 at 7.5-9.0 inches.

That makes wheel diameter the first checkpoint and rim width the second. A 17-inch Subaru wheel can only be considered for another 17-inch size, and then only if its width suits the tire you want to mount. Owners swapping wheels between Impreza, Legacy, Outback, BRZ, and WRX applications should verify both measurements rather than assuming Subaru-to-Subaru interchangeability at the tire level.

A 2019 Subaru that spends long periods parked should be stored out of direct sunlight, away from electric motors or ozone-producing equipment, and on a clean, dry surface. Keep the tires properly inflated during storage, and if the car will sit for an extended period, rolling it occasionally helps reduce flat-spotting in the tread contact area. Because every 2019 Subaru fitment here is radial, storage concerns are more about age, pressure retention, and environmental exposure than vintage-style bias-ply behavior.

For collector or seasonal use, many owners add tire cradles or support the car in a way that reduces prolonged stress on one contact patch. That is especially worthwhile on lower-profile WRX, WRX STI, and BRZ tires, which have less sidewall compliance than taller Outback or Legacy fitments. A few minutes of storage planning can preserve ride quality and sidewall appearance over time.

Tire age is often more important than mileage on a lightly used 2019 Subaru. A good rule is to begin evaluating tires closely once they are around five to seven years old and to treat roughly ten years from the DOT date code as the point where replacement deserves serious consideration, even if tread depth still looks acceptable. Heat cycles, storage conditions, inflation history, and exposure to sunlight all affect the timeline.

That matters because many enthusiast cars, second vehicles, and low-mileage daily drivers wear out tires by age before they wear them out by tread use. Check the DOT date code, inspect for sidewall cracking and hardening, and do not assume a tire is healthy just because it looks good from a distance. On a performance-oriented Subaru, aging rubber can noticeably change ride and handling long before the tread is gone.

Tires on a 2019 Subaru should be inspected before every drive and given a more careful check before any longer trip. Look for cracking, cuts, punctures, bulges, unusual shoulder wear, and signs of slow pressure loss. Lower-profile fitments such as 225/40R18, 245/40R18, 245/35R19, and 265/35R19 deserve especially close attention because impact damage from potholes can be easier to miss until it becomes serious.

A quick visual walkaround catches many problems early, while a monthly pressure check helps protect both tire life and handling consistency. Include the spare if the car has one, since emergency tires often age quietly in the trunk or cargo area. If the Subaru sees spirited driving, inspect more often, because repeated heat and cornering loads can reveal issues sooner than routine commuting.

A 2019 Subaru BRZ belongs to an era where radial construction is standard, and the fitment family here reflects that entirely. Within this year-and-make range, the BRZ uses 215/45R17 as its size, mounted on a 17-inch wheel, with modern radial performance tires forming the appropriate replacement category. There is no need to chase older construction types for authenticity on a vehicle from this period.

For an owner interested in correctness, the main goal is keeping the factory-style size and overall visual character rather than reproducing an antique sidewall treatment or obsolete construction. If your BRZ has aftermarket wheels, return first to the original size logic before making product choices. For trim-specific factory confirmation, the owner’s manual and marque-focused Subaru communities remain the best references.

Yes, correct tire fitment still matters when a 2019 Subaru is judged or displayed seriously, even though the standards are different from those used for older collector cars. Judges and knowledgeable enthusiasts will notice whether the size, wheel diameter, and sidewall appearance suit the specific model. A BRZ on the wrong profile, an Outback on a mismatched low-profile size, or a WRX STI without its proper 19-inch fitment can look obviously off to anyone familiar with the platform.

The right approach is to keep the tire size aligned with the model and wheel package the car is meant to wear. On a modern Subaru, authenticity usually means the correct metric radial sizing and a sidewall style that looks appropriate for a late-2010s Japanese performance or passenger-car application. If the car is headed to marque judging, compare against Subaru literature and event-specific standards before making a cosmetic tire change.

On several 2019 Subaru performance sizes, BFGoodrich g-Force Phenom T/A and Nitto NT555 G2 overlap in fitment but differ in details such as speed rating availability, published load figures, and in some cases rim-width presentation. In 245/40R18, for example, the BFGoodrich Phenom T/A carries a W rating and a 1,389-pound load figure at 50 psi, while the Nitto NT555 G2 also carries a W rating with a 1,609-pound load figure at 50 psi. In 265/35R19, BFGoodrich reaches a Y rating while Nitto remains W-rated.

That kind of comparison matters more than brand name alone on a modern enthusiast Subaru. If two products fit the same WRX or WRX STI size, compare the sidewall marking, speed symbol, load figure where shown, and approved rim-width range before choosing. The better match is the one that aligns with how the car is driven and how closely you want to stay to the intended wheel-and-tire package.

Yes, the 2019 Subaru sizes covered here are modern radial tires suitable for normal highway use when they are in good condition, properly inflated, and matched to the correct wheel. Most products carry W speed ratings with a 112 mph ceiling, some 205/55R16 and 245/40R18 products reach Y at 186-plus mph, and 225/65R17 appears with an S rating to 112 mph. In real use, the vehicle’s mechanical condition, alignment, brakes, and suspension usually matter at least as much as the tire’s speed symbol.

Highway safety depends on condition and correctness more than on chasing the highest letter on the sidewall. A fresh, properly sized tire on the right wheel is far more valuable than an aggressive rating on an aged or mismatched tire. Before sustained interstate driving, confirm pressure, inspect the tread and sidewalls, and make sure all four tires suit the model’s intended fitment.

The right inflation pressure for a 2019 Subaru should come from the vehicle’s tire placard or owner’s manual for normal service, while the tire’s own maximum-pressure marking is part of its rated load capacity rather than a universal running recommendation. Published load-and-pressure figures vary by size and product, including 1,356 pounds at 50 psi on some 215/45R17 tires, 1,819 pounds at 50 psi on some 225/55R17 tires, 2,150 pounds at 65 psi on 225/65R17, and 1,653 pounds at 50 psi on some 265/35R19 tires.

The key point is not to transfer a pressure figure from one Subaru size to another. An Outback all-terrain fitment and a WRX STI low-profile fitment operate in very different load and wheel environments, even if both are radial tires from the same brand family. Use the car’s factory recommendation as your baseline and adjust only within the tire maker’s approved limits when a specific use case calls for it.

Before a longer trip in a 2019 Subaru, inspect each tire for sidewall cracking, punctures, tread damage, bulges, and uneven wear, then verify cold inflation pressure and make sure the valve stems are sound. Confirm that the size on the car matches the wheel and model, especially if the Subaru was purchased used or modified by a previous owner. Lower-profile WRX, WRX STI, and BRZ tires deserve an extra look for impact damage from potholes or curb contact.

Tires are only one part of the pre-trip checklist, but they are among the easiest components to evaluate before trouble starts. Also check the spare or inflation kit, inspect the brakes visually, and make sure the car tracks straight without vibration during a short test drive. If anything feels off, fix it before the trip rather than assuming the issue will stay minor.
