The 1991 Subaru XT came from an era when Subaru was experimenting with sharp aerodynamic styling and distinctly futuristic coupe design. That shape still gives the XT a character all its own, but it also means tire selection needs to stay closely tied to the exact version of the car. For 1991, the Subaru XT uses three radial tire sizes across the GL, XT6 4WD, and XT6 FWD sub-models, split between 13-inch and 14-inch rims. Available choices range from traditional blackwall radials to redline and wide whitewall offerings in 185/70R13. The right decision starts with identifying the exact sub-model and wheel diameter before comparing appearance, series, and road-use priorities.
Which Tire Size Is Right for The 1991 Subaru XT
Three tire sizes apply to the 1991 Subaru XT, and the correct choice depends on the specific sub-model and wheel diameter. The GL uses a 13-inch radial, while XT6 models use 14-inch radials in two different sizes depending on front-wheel-drive or four-wheel-drive configuration. Before choosing a tire, confirm both the exact sub-model and the actual wheel setup on the car, especially if wheels have ever been changed.
185/70R13 is a metric radial size in which 185 refers to nominal section width in millimeters, 70 is the aspect ratio, R indicates radial construction, and 13 is the rim diameter in inches. On the 1991 Subaru XT, this size is used on the GL and represents a modern radial fitment rather than an older bias-ply format. Available choices include BFGoodrich, Avon, Dunlop, Michelin, and Vredestein, with blackwall, redline, and wide whitewall sidewall treatments. This size gives the most visible appearance choices, so it matters to buyers balancing original-era character with actual driving plans.
205/60R14 is a metric radial size where 205 is the nominal section width in millimeters, 60 is the aspect ratio, R denotes radial construction, and 14 identifies the wheel diameter in inches. On the 1991 Subaru XT, this size belongs to the XT6 4WD configuration, so it should not be treated as universal across the full model line. Its lower-profile metric format reflects the more specific wheel and tire setup used on that sub-model. Choosing this size starts with confirming the car is truly an XT6 4WD and still wears the correct 14-inch wheels.
195/60R14 is a metric radial size with a 195-millimeter nominal section width, a 60-series profile, radial construction, and a 14-inch rim diameter. This size is used on the 1991 Subaru XT XT6 FWD, making it specific to that front-wheel-drive configuration rather than the entire XT range. Michelin offers this fitment in the MXV3-A series with a blackwall sidewall, keeping the choice straightforward within the correct size. The key here is matching the tire to the actual FWD XT6 setup and verifying that the car has not been converted to a different wheel package over the years.
Sub-model fitment matters on the 1991 Subaru XT because tire size changes across the GL, XT6 4WD, and XT6 FWD. Before comparing products, confirm the exact version of the car and whether it still has its proper 13-inch or 14-inch wheels.

1991 Subaru XT GL
The 1991 Subaru XT GL uses the 185/70R13 radial size. That opens the broadest range of product and appearance choices, including blackwall, redline, and wide whitewall options, so the decision becomes one of style, series, and intended use rather than size confusion.
The 1991 Subaru XT XT6 (4WD) uses the 205/60R14 radial size. Tire selection for this sub-model starts with confirming the 14-inch wheel setup, since this fitment is unique to the 4WD XT6 and should be matched carefully to the car's current wheels.
The 1991 Subaru XT XT6 (FWD) uses the 195/60R14 radial size. With this sub-model, the main priority is verifying the FWD configuration and 14-inch wheel diameter so the tire choice stays aligned with the specific XT6 setup on the car.
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.

Tire Size & Fitment
What tire size fits a 1991 Subaru XT?
The 1991 Subaru XT uses three different radial tire sizes depending on sub-model. The XT GL uses 185/70R13, the XT6 (4WD) uses 205/60R14, and the XT6 (FWD) uses 195/60R14. That means there is no single tire size that covers every 1991 XT configuration.
The first step is confirming whether the car is a GL, XT6 4WD, or XT6 FWD, then matching that to the wheel diameter actually on the vehicle. Many surviving specialty coupes have seen wheel changes over time, so checking both the sub-model and the current rim size helps avoid choosing a tire that matches the badge but not the setup on the car.
What size rim does a 1991 Subaru XT use?
A 1991 Subaru XT uses either a 13-inch or 14-inch rim, depending on sub-model. The GL uses a 13-inch tire fitment, while the XT6 4WD and XT6 FWD use 14-inch tire fitments. Rim diameter is part of the tire size itself, so it needs to match exactly.
Wheel diameter should be checked before anything else, especially on a car with unknown history or aftermarket wheels. A tire sized for a 13-inch rim cannot be mounted on a 14-inch wheel, and the reverse is just as true. Once rim diameter is confirmed, compare the exact tire size, the wheel width where available, and the remaining clearance around the suspension and body.
Why does the 1991 Subaru XT have more than one tire size?
The 1991 Subaru XT has more than one tire size because the GL and XT6 variants do not share the same wheel and tire package. The GL uses 185/70R13, while XT6 models move to 14-inch radial sizes, with 205/60R14 on the 4WD version and 195/60R14 on the FWD version.
That difference means the right tire choice starts with the exact sub-model, not just the model name. A buyer should also confirm that the current wheels still match the intended configuration, since older enthusiast cars are often modified. Once the correct size is established, product selection becomes much easier because the search narrows to the proper diameter and profile.
Choosing the Right Tire
What should I consider when choosing a 185/70R13 tire for a 1991 Subaru XT?
For a 1991 Subaru XT GL, the main considerations are staying with the correct 185/70R13 size, choosing a radial that suits the car's intended use, and deciding how much visual emphasis you want from the sidewall. Available options include blackwall, redline, and wide whitewall designs across several brands and tire series.
After the size is confirmed, compare practical details such as compatible rim-width ranges where stated, load figures when given, and whether the tire's look suits a stock-style or more personalized presentation. A blackwall usually keeps the appearance understated, while redline or wide whitewall choices make a stronger visual statement on a coupe with standout 1990s styling.
What sidewall styles are available for 1991 Subaru XT tires?
Sidewall style depends on the tire size, but the 1991 Subaru XT has meaningful variety in 185/70R13. That size is available in blackwall, redline, and wide whitewall treatments. The 195/60R14 fitment shown here appears in blackwall form, making the most visible style choice concentrated in the GL's 13-inch size.
Choosing a sidewall treatment is mostly an appearance decision once the correct size has been established. Blackwall tends to suit a clean, understated road-car look, while redline and wide whitewall options push the XT toward a more stylized period presentation. The important step is keeping the right size and rim compatibility first, then selecting the sidewall that matches the car's personality.
What brands offer tires for the 1991 Subaru XT?
Brands available for 1991 Subaru XT tire fitments include BFGoodrich, Avon, Dunlop, Michelin, and Vredestein. The broadest selection appears in 185/70R13, while the 195/60R14 fitment shown here is available from Michelin. Brand choice is only part of the decision, since tire series and sidewall treatment also vary.
A useful way to compare them is by matching the tire to the exact sub-model first and then looking at the character of the tire within that size. Some choices lean toward a traditional collector look, while others present a more performance-oriented visual style. Rim-width guidance, sidewall appearance, and the car's intended road use usually matter more than brand name alone.
Restoration & Appearance
Which tire should I choose for a period-style 1991 Subaru XT?
A period-style 1991 Subaru XT tire choice starts with the correct size for the exact sub-model: 185/70R13 for the GL, 205/60R14 for the XT6 4WD, or 195/60R14 for the XT6 FWD. From there, a radial with a traditional blackwall presentation usually keeps the look closest to an era-appropriate street-car appearance.
The GL offers the most visual flexibility because 185/70R13 is also available in redline and wide whitewall form. Those options can create a more customized period flavor, but they are appearance choices rather than proof of exact factory originality. For a highly detailed restoration, compare the tire selection against period photos, brochures, or marque-specific references before settling on a sidewall style.
Does correct tire fitment matter for a 1991 Subaru XT restoration?
Correct tire fitment matters on a 1991 Subaru XT restoration because the car's low, wedge-shaped proportions make wheel diameter and tire profile especially visible. Using the right size helps preserve the intended stance and prevents the car from looking over-tired, under-tired, or visually out of scale with its original design language.
Fitment also affects practical details beyond appearance. A mismatched diameter or profile can create avoidable clearance issues or alter the overall visual balance between the tire, wheel opening, and body line. Even on a driver-quality restoration, confirming sub-model, rim diameter, and current wheel setup is worth the effort before choosing among available brands, sidewalls, and tire series.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1991 Subaru XT?
Yes, modifications can affect tire fitment on a 1991 Subaru XT. Aftermarket wheels, suspension changes, altered ride height, or body modifications can all change whether the original-size tire remains the best match for the car's current setup. That matters even more on the XT because the model already uses different tire sizes across its sub-model range.
A modified car should be checked for actual wheel diameter, wheel width, and clearance at the fenders and suspension before a tire is selected. Steering travel is worth verifying as well, especially on front tires. Even when the tire size sounds correct for the badge on the car, the present wheel and suspension package is what ultimately determines whether that fitment still makes sense.
What should I inspect before driving a 1991 Subaru XT on new tires?
Before driving a 1991 Subaru XT on new tires, inspect the wheels for damage, confirm the tire size matches the sub-model and rim diameter, and check that the tires are inflated properly for the setup being used. It is also smart to look over the valve stems and make sure there are no mounting or sealing issues after installation.
A road-ready inspection should include suspension condition, brake function, and tire clearance at full steering lock, especially on a car that may have sat for long periods. Older coupes can hide worn bushings, weak shocks, or alignment issues that show up quickly once fresh tires are installed. A careful first drive followed by a pressure and visual recheck helps catch small problems before they become bigger ones.
How should tires on a collector 1991 Subaru XT be maintained?
Tires on a collector 1991 Subaru XT should be maintained with regular pressure checks, routine visual inspection, and attention to age-related deterioration as well as tread wear. Low-use cars often develop problems from sitting, so sidewall cracking, flat spotting, cuts, bulges, and slow air loss deserve as much attention as mileage-based wear.
Storage conditions matter too. Keeping the XT away from prolonged sunlight, excess heat, moisture, and ozone sources helps protect the tire casing over time. Moving the car periodically and checking the tires before each drive is a good habit, particularly if the car is used seasonally. Any sign of structural damage or persistent pressure loss calls for a closer inspection by a qualified tire professional.
