1998 Buick Regal Tires

A 1998 Buick Regal uses either 225/60R16 or 215/70R15, depending on the sub-model. The 25th Anniversary Edition and GS use 225/60R16 radial tires, while the LS uses 215/70R15 radial tires. Those are different primary fitments, not interchangeable descriptions of the same wheel setup.

The practical step is to confirm the trim and wheel diameter before choosing a tire. A Regal that has been fitted with different wheels over the years may not still match its original sub-model setup, so checking the wheel itself helps avoid ordering the right tire size for the wrong rim.

The 1998 Buick Regal uses either a 16-inch rim or a 15-inch rim, depending on the sub-model. Cars fitted with 225/60R16 tires use a 16-inch rim, while cars fitted with 215/70R15 tires use a 15-inch rim. The wheel diameter follows the tire size rather than applying across the whole Regal lineup.

That makes wheel confirmation especially important before replacing tires. Looking only at the model year is not enough, because the Regal was offered with more than one tire-and-wheel combination. If the car has aftermarket wheels, verify both diameter and suitable wheel width before narrowing the choice to a specific tire.

No. The 1998 Buick Regal lineup uses two different tire sizes across its sub-models. The 25th Anniversary Edition and GS use 225/60R16, while the LS uses 215/70R15. All of them use radial construction, but the wheel diameter and tire size differ by trim.

That means the sub-model name matters before comparing brands or sidewall styles. Once the trim is confirmed, the tire decision becomes much simpler because the available products can be narrowed to the correct wheel diameter first, then compared by appearance, rim-width suitability, and the kind of driving the car will see.

Start with the correct trim-specific size: 225/60R16 for the GS and 25th Anniversary Edition, or 215/70R15 for the LS. From there, compare radial construction details such as rim-width suitability, sidewall style, brand, tire series, and load figures where they are stated. The right choice depends on both fitment and the look you want.

Some Regal owners want a cleaner blackwall or touring-style presentation, while others prefer raised white letters, redlines, or whitewalls that change the car’s character visually. It also helps to confirm whether the car is used mainly for local cruising, regular road miles, or appearance-focused restoration work before narrowing the selection.

Sidewall choices for the 1998 Buick Regal include blackwall, raised white letter, raised-yellow-letter, redline, pin-white-stripe, narrow whitewall, and wide whitewall, depending on the tire size. The 225/60R16 selection leans heavily toward appearance options, while the 215/70R15 range includes an even broader spread of traditional and sport-oriented styles.

That variety lets the tire influence the Regal’s overall presentation without changing the primary fitment. A GS owner may lean toward a more performance-themed sidewall, while an LS owner may prefer a whitewall or stripe treatment that suits a more formal Buick look. Keeping the correct size comes first, then the sidewall style becomes the visual decision.

Brands available for 1998 Buick Regal tire sizes include Goodyear, BFGoodrich, Travelstar, Cooper, Dunlop, Avon, Michelin, Maxxis, Coker Classic, and Vredestein. Brand availability depends on the tire size, with 215/70R15 offering the widest mix and 225/60R16 offering a smaller but still varied selection of radial options.

The useful comparison is not just brand name but how each option is presented within the correct size. One brand may offer a blackwall, another a whitewall, and another a redline or raised-letter treatment. Looking at brand alongside tire series, sidewall design, and wheel compatibility gives a much clearer buying picture than brand alone.

A period-style 1998 Buick Regal tire starts with the correct size for the exact sub-model, then moves to appearance. For a GS or 25th Anniversary Edition, that means choosing within 225/60R16. For an LS, it means staying with 215/70R15. From there, sidewall style and tire series help shape whether the car looks more sporty, formal, or understated.

Redlines, raised white letters, pin stripes, and whitewalls can all shift the Regal’s visual tone without changing the basic fitment. When exact originality matters, appearance choices should be checked against vehicle-specific historical references or marque guidance rather than assumed from size alone. For most owners, the goal is a convincing late-1990s, period-appropriate presentation.

Construction is straightforward on the 1998 Buick Regal because both primary fitments on this page are radial tires. The visual difference comes less from bias-ply versus radial choice and more from the sidewall treatment, tire series, and how the tread and profile suit the car’s late-1990s Buick character.

That gives a restoration-minded owner room to shape the car’s look while staying within the correct radial format. A blackwall can keep the appearance clean and restrained, while redlines, raised letters, or whitewalls make a much stronger statement. The best result usually comes from matching the tire’s visual style to the Regal’s trim level and intended presentation.

Yes. Modifications can change tire fitment on a 1998 Buick Regal even when the tire size itself is correct for the original sub-model. Different wheels, altered wheel widths, suspension changes, or body modifications can all affect clearance and how the tire sits on the car. That matters on both the 15-inch and 16-inch Regal setups.

A Regal with aftermarket wheels should be checked for actual wheel diameter and width before choosing a replacement tire. It also helps to inspect steering clearance, fender room, and suspension condition, especially if the car has been lowered or updated. A correct catalog size is only the starting point when the vehicle has been modified.

Before driving a 1998 Buick Regal on new tires, inspect the wheels for damage, confirm lug hardware is correct, and make sure the tire size matches the wheel diameter on the car. It is also wise to check alignment, suspension wear, and basic brake condition so the new tires are not working against existing mechanical problems.

Once the tires are mounted, look for proper clearance at full steering lock and during normal suspension movement. Tire pressure should be set appropriately for the tire and vehicle setup, and the first few drives should include a quick follow-up check for rubbing, vibration, or air loss. That extra inspection helps catch fitment or installation issues early.

Tires on a 1998 Buick Regal should be inspected regularly, especially on a car that sees occasional use or long periods of storage. Look over tread wear, sidewall condition, cracking, bulges, cuts, and any sign of uneven wear. Pressure loss is also worth watching closely, since a collector or weekend-driven car may sit longer between outings.

A quick inspection before longer drives is a good habit even when the tires still look presentable. On a Regal that spends much of its time parked, age and storage conditions matter almost as much as tread depth. Keeping the car away from prolonged sunlight, heat, moisture, and ozone sources can help preserve the tires between drives.
