The 1998 Subaru Legacy sits in the era when Subaru had firmly established the Legacy as a practical all-weather passenger car with wagon and sedan variants that appealed to daily drivers and long-distance owners alike. By this point, trim differences mattered because the Legacy range stretched from straightforward base models to sportier GT versions and the more adventure-oriented Outback. Tire selection follows that spread closely, with 185/70R14, 205/70R15, and 205/55R16 radial fitments depending on sub-model. Available choices range from blackwall touring and sport-oriented radials to wide and narrow whitewall options. The key is matching the exact sub-model and wheel diameter before comparing style, series, and intended road use.
Which Tire Size Is Right for The 1998 Subaru Legacy
The 1998 Subaru Legacy uses three primary tire sizes, and the right one depends on the exact sub-model and wheel diameter. Base, Brighton, L, and Postal models use 185/70R14, GT and GT Limited models use 205/55R16, and Outback and SVS models use 205/70R15. Before choosing a tire, confirm which Legacy version you have and verify that the wheels on the car still match the original rim diameter for that fitment.
185/70R14 is a metric radial size: 185 is the nominal section width in millimeters, 70 is the aspect ratio, R indicates radial construction, and 14 is the wheel diameter in inches. On the 1998 Subaru Legacy, this size is used on several non-GT sub-models and keeps the fitment centered on a 14-inch wheel. Available choices include blackwall designs from Avon, Dunlop, Michelin, and Vredestein, along with a wide whitewall BFGoodrich Silvertown Radial. It is the size to evaluate when the car retains its 14-inch setup and the goal is to balance correct fitment with the preferred appearance and tire character.
205/55R16 is a metric radial size with a 205-millimeter nominal section width, a 55-series profile, radial construction, and a 16-inch rim diameter. This fitment belongs to the 1998 Subaru Legacy GT and GT Limited, so it carries a lower-profile look than the 14-inch and 15-inch Legacy sizes. Product choices in this size include several blackwall performance-oriented series from BFGoodrich and Michelin, plus a wide whitewall American Classic Radial. It is the right size to consider when the car uses the original 16-inch GT wheel diameter and the decision comes down to tire character, sidewall style, and wheel-width compatibility.
205/70R15 is a metric radial size that combines a 205-millimeter nominal section width with a 70-series profile on a 15-inch wheel. On the 1998 Subaru Legacy, this size is used by the Outback and SVS, making wheel diameter confirmation especially important before comparing tires. The range includes blackwall options from Michelin, Avon, and Dunlop, along with narrow and wide whitewall choices from Maxxis, American Classic, Coker Classic, Tornel, and Travelstar. This is the fitment to focus on when selecting for a 15-inch Legacy setup and deciding between a more contemporary blackwall presentation or a more traditional whitewall look.
Sub-model fitment on the 1998 Subaru Legacy is not one-size-fits-all, because the covered versions use three different tire sizes across three different rim diameters. Checking the exact sub-model matters first, since the correct tire choice starts with matching the car's original wheel diameter and trim-specific fitment.

1998 Subaru Legacy Base
The 1998 Subaru Legacy Base uses a 185/70R14 radial tire. That keeps tire selection focused on the 14-inch fitment, where the main decision is usually between blackwall touring-style choices and a restoration-flavored whitewall presentation.
The 1998 Subaru Legacy Brighton uses the same 185/70R14 radial fitment as other 14-inch Legacy trims. Tire selection comes down to confirming the car still has 14-inch wheels and then choosing among the available brands, series, and sidewall styles in that size.
The 1998 Subaru Legacy GT uses a 205/55R16 radial tire. That makes wheel confirmation important, because this trim's 16-inch fitment points the buyer toward lower-profile blackwall performance-oriented options or a whitewall alternative in the same size.
The 1998 Subaru Legacy GT Limited also uses 205/55R16 radial tires. For this sub-model, the practical choice is less about size and more about selecting the right tire character, sidewall treatment, and wheel-width compatibility within the 16-inch fitment.
The 1998 Subaru Legacy L uses a 185/70R14 radial tire. Owners should center the search on the 14-inch setup first, then compare available blackwall and whitewall choices according to appearance, driving use, and the wheel dimensions on the car.
The 1998 Subaru Legacy Outback uses a 205/70R15 radial tire. That places the focus on the 15-inch fitment, where buyers can compare blackwall, narrow whitewall, and wide whitewall options depending on the intended look and road-use style.
The 1998 Subaru Legacy Postal uses a 185/70R14 radial tire. The selection process stays straightforward as long as the vehicle still carries its 14-inch wheels, after which the choice becomes brand, series, and sidewall appearance within that size.
The 1998 Subaru Legacy SVS uses a 205/70R15 radial tire. That means the buyer should verify the 15-inch wheel setup first, then compare the available tires by sidewall style, series, and overall presentation rather than by 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)
Body alterations (fender modifications, custom bodywork)
If your vehicle has been modified from factory specifications, verify tire clearance before purchase.

Common 1998 Subaru Legacy tire questions usually come down to sub-model-specific sizing, wheel diameter, sidewall style, and how to choose among the available radial options for 14-inch, 15-inch, or 16-inch setups.
Tire Size & Fitment
What tire size fits a 1998 Subaru Legacy?
A 1998 Subaru Legacy can use 185/70R14, 205/70R15, or 205/55R16, depending on the sub-model. Base, Brighton, L, and Postal models use 185/70R14, GT and GT Limited models use 205/55R16, and Outback and SVS models use 205/70R15. All three are radial fitments, but they are not interchangeable primary sizes across the whole Legacy line.
The first step is identifying the exact Legacy sub-model and confirming the wheel diameter on the car. Many older vehicles have had wheel changes over time, so checking the current wheel size matters just as much as knowing the trim. Once that is settled, the choice shifts to sidewall style, tire series, and the kind of road use the car actually sees.
What size rim does a 1998 Subaru Legacy use?
The 1998 Subaru Legacy uses three rim diameters across the model range: 14-inch, 15-inch, and 16-inch. The 185/70R14 fitment uses a 14-inch rim, 205/70R15 uses a 15-inch rim, and 205/55R16 uses a 16-inch rim. Rim diameter follows the tire size, so the correct wheel size depends on which Legacy sub-model is being fitted.
Checking rim diameter is essential before comparing tires because a 14-inch tire cannot be mounted on a 15-inch or 16-inch wheel, and the same is true in reverse. It is also worth confirming wheel width when comparing product options, especially if the car has aftermarket wheels or if the wheel setup has changed since new.
Do all 1998 Subaru Legacy sub-models use the same tire size?
No, 1998 Subaru Legacy sub-models do not all use the same tire size. Several trims share 185/70R14, GT and GT Limited use 205/55R16, and Outback and SVS use 205/70R15. Subaru spread the Legacy range across multiple trim and wheel packages, so tire fitment changes with the specific version of the car.
That means tire selection should start with the exact sub-model rather than the model name alone. A Legacy owner looking at tires for a GT will be shopping a different wheel diameter and tire profile than an owner of a Base or Outback model. Verifying the trim and the wheels on the vehicle prevents ordering the right style in the wrong size.
Choosing the Right Tire
What should I consider when choosing a tire for a 1998 Subaru Legacy?
Start with the correct size for the exact 1998 Subaru Legacy sub-model, then compare the tire's construction, wheel-diameter match, and intended character. This Legacy range uses radial tires in 185/70R14, 205/70R15, and 205/55R16. From there, the meaningful differences are sidewall appearance, brand, tire series, and wheel-width compatibility within the chosen size.
A Base or Brighton owner may prioritize a more traditional-looking 14-inch radial, while a GT owner may focus on lower-profile 16-inch options. Outback and SVS owners have a broader 15-inch selection that includes blackwall and whitewall styles. Matching the tire to the car's actual wheel setup and the way the vehicle is driven usually matters more than picking by brand name alone.
What sidewall styles are available for 1998 Subaru Legacy tires?
Sidewall choices for the 1998 Subaru Legacy include blackwall, narrow whitewall, and wide whitewall, depending on tire size. The 185/70R14 fitment includes mostly blackwall options plus a wide whitewall choice. The 205/55R16 fitment offers blackwall and wide whitewall options, while 205/70R15 adds blackwall, narrow whitewall, and wide whitewall choices.
That variety makes sidewall style an appearance decision as much as a fitment decision. Blackwalls usually suit a more contemporary or understated look, while whitewalls create a stronger vintage-style presentation even on a newer classic-era car. The right choice depends on the Legacy's visual direction, but the selected tire still needs to match the proper size and wheel dimensions first.
What brands offer tires for the 1998 Subaru Legacy?
Tires for the 1998 Subaru Legacy are available from several brands, including BFGoodrich, Avon, Dunlop, Michelin, Vredestein, American Classic, Maxxis, Coker Classic, Tornel, and Travelstar. Brand availability depends on the specific Legacy tire size, so the mix changes between 185/70R14, 205/55R16, and 205/70R15 fitments. Some sizes lean toward blackwall sport or touring selections, while others add whitewall-focused choices.
Brand should be compared alongside tire series, sidewall treatment, and wheel-width suitability rather than treated as the only factor. A GT owner shopping 205/55R16 will be looking at a different group of products than an Outback owner using 205/70R15. Once the correct size is confirmed, the better comparison is which available tire matches the car's look and use.
Restoration & Appearance
Which tire should I choose for a period-style 1998 Subaru Legacy?
A period-style 1998 Subaru Legacy tire choice starts with the sub-model's correct size, then narrows by appearance. The 14-inch, 15-inch, and 16-inch Legacy fitments all have radial options, and some sizes include whitewall versions alongside blackwalls. For a more restrained late-1990s look, blackwall tires usually keep the presentation closest to how many Legacy models were commonly seen on the road.
If the goal is a restoration-oriented presentation rather than strict originality, whitewall options can create a distinctive traditional look in the proper size. Exact original appearance can vary by trim, market, and prior wheel changes, so owners pursuing precise authenticity should compare the car against period photos, original literature, or marque-specific references before settling on a sidewall style.
Does correct tire fitment matter for a 1998 Subaru Legacy restoration?
Correct tire fitment matters on a 1998 Subaru Legacy restoration because the right size affects both the vehicle's stance and the relationship between the tire and the wheel opening. Using the proper 14-inch, 15-inch, or 16-inch Legacy fitment keeps the restoration grounded in the trim-specific setup. It also helps avoid a mismatch between the sub-model and the wheel diameter being used.
Appearance is only part of the equation. Proper fitment also means checking that the wheels on the car still correspond to the intended trim, especially if the vehicle has been modified during its life. Once the correct size is confirmed, the remaining restoration choice is whether the Legacy should wear a simple blackwall look or a more stylized whitewall presentation.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1998 Subaru Legacy?
Yes, modifications can affect tire fitment on a 1998 Subaru Legacy. Wheel changes, suspension alterations, lowering, and body modifications can all change the space available for the original tire size. That matters because this Legacy family already uses three different factory wheel diameters, so a modified car may no longer match the trim-based fitment it started with.
A Legacy with aftermarket wheels should be checked for actual wheel diameter and width before selecting tires. Steering clearance, fender clearance, and suspension travel are worth reviewing as well, especially on GT or Outback models where profile and wheel size differ noticeably. Even when the tire size looks close on paper, the real vehicle setup still determines whether the choice is appropriate.
What should I inspect before driving a 1998 Subaru Legacy on new tires?
Before driving a 1998 Subaru Legacy on new tires, inspect the wheels for the correct diameter and visible damage, and make sure the new tire size matches the sub-model. It is also smart to check valve stems, wheel balance, and general condition around the suspension and steering. A new tire cannot correct problems caused by bent wheels, worn components, or an incorrect wheel setup.
Once mounted, verify inflation pressure, look for any signs of rubbing at full steering lock, and make sure the tires clear the fenders and inner wheelhouse during normal suspension movement. A short local test drive helps confirm that the car tracks properly and that there are no vibrations, air-loss issues, or clearance problems before taking the Legacy on a longer run.
How should tires on a 1998 Subaru Legacy be maintained?
Tires on a 1998 Subaru Legacy should be maintained with regular pressure checks, visual inspections, and attention to age as well as tread. Look for uneven wear, cracking, cuts, bulges, and slow air loss, especially if the car sees limited seasonal use. Maintenance starts with the basics, but it should also include checking that the tire still matches the wheel and sub-model it is intended for.
Collector and occasional-use cars can age out their tires long before the tread is gone, so condition matters more than mileage alone. Keeping the Legacy stored away from prolonged sunlight, moisture, and ozone sources can help preserve the tires between drives. It is also wise to inspect the spare and recheck pressures before any highway trip or extended road use.
