The 1993 Buick Regal sits in the last stretch of Buick’s long-running personal-luxury midsize tradition, blending front-wheel-drive practicality with the smoother, more formal character many Regal buyers still wanted in the early 1990s. Tire selection on this model is configuration-specific, with 205/70R15 used on Custom and Limited trims and 225/60R16 used on the Gran Sport, so wheel diameter and sub-model matter from the start. All primary fitments are radial, but the available choices vary widely in sidewall presentation, from blackwall and narrow whitewall to wide whitewall, redline, and raised yellow letter styling. The right choice depends on whether the goal is stock-type road use, a stronger period-style appearance, or matching an already changed wheel setup.
Which Tire Size Is Right for The 1993 Buick Regal
Two tire sizes apply to the 1993 Buick Regal, and the correct one depends on the exact sub-model and wheel diameter. Custom and Limited models use a 15-inch fitment with 205/70R15, while the Gran Sport uses a 16-inch fitment with 225/60R16. Before comparing brands or sidewall styles, confirm whether the car is a Custom, Gran Sport, or Limited and verify that the wheels on the car still match that original diameter.
In 205/70R15, the 205 identifies nominal section width in millimeters, the 70 is the aspect ratio, the R indicates radial construction, and the 15 is the wheel diameter in inches. This is a modern metric radial size used on certain 1993 Buick Regal trims and suits the Regal’s late-classic mix of comfort and everyday drivability. Available choices include blackwall, narrow whitewall, and wide whitewall designs from brands such as Maxxis, Michelin, Avon, American Classic, Coker Classic, Dunlop, Tornel, and Travelstar. It is the right size to evaluate when keeping a 15-inch Regal setup or maintaining a more traditional luxury-car appearance.
In 225/60R16, the 225 is the nominal section width in millimeters, the 60 is the aspect ratio, the R marks radial construction, and the 16 designates a 16-inch wheel. This modern metric radial size belongs to the 16-inch Regal fitment and gives the buyer a distinctly different selection path than the 15-inch cars. Product choices include raised yellow letter, redline, pin-white-stripe, wide whitewall, and narrow whitewall styles from Goodyear, BFGoodrich, and Travelstar. It deserves a close look when the car is a Gran Sport or when the wheel package has already been confirmed as 16 inch.
Sub-model identification matters on the 1993 Buick Regal because tire fitment is not the same across the range. Custom and Limited share one size, while the Gran Sport uses a different size and wheel diameter, making trim and wheel confirmation the first step before comparing tire options.

1993 Buick Regal Custom
The 1993 Buick Regal Custom uses the 205/70R15 radial fitment. That keeps tire selection focused on choosing the right sidewall style, brand, and overall presentation for a 15-inch Regal rather than sorting through multiple primary sizes.
The 1993 Buick Regal Gran Sport uses the 225/60R16 radial fitment. Tire choice here centers on confirming the 16-inch wheel setup and then deciding among appearance-driven options such as raised yellow letter, redline, whitewall, or blackwall-adjacent performance-style presentation.
The 1993 Buick Regal Limited uses the 205/70R15 radial fitment. Buyers can concentrate on the character of the replacement tire, especially whether the car calls for a clean blackwall look or a more traditional whitewall treatment that suits Buick’s upscale image.
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 1993 Buick Regal tire questions usually center on the split between 15-inch and 16-inch fitments, trim-specific sizing, sidewall style choices, and what to inspect before putting a collector-era or low-mile Regal back on the road.
Tire Size & Fitment
What tire size fits a 1993 Buick Regal?
A 1993 Buick Regal uses one of two radial tire sizes: 205/70R15 or 225/60R16. The 205/70R15 size belongs to the Regal Custom and Regal Limited, while the 225/60R16 size belongs to the Regal Gran Sport.
The practical decision starts with confirming the exact trim and the actual wheels on the car. Many older Regals have seen wheel changes over time, so the safest approach is to match the tire size to both the sub-model and the wheel diameter currently installed before comparing brands, sidewall styles, or tire series.
What size rim does a 1993 Buick Regal use?
The 1993 Buick Regal uses either a 15-inch or 16-inch rim, depending on sub-model. Regal Custom and Limited models use a 15-inch rim with 205/70R15 tires, while the Regal Gran Sport uses a 16-inch rim with 225/60R16 tires.
That difference matters because tire diameter markings and wheel diameter must match exactly. Before selecting a replacement tire, check the wheel itself and the tire sidewall already on the car, especially if the Regal has aftermarket wheels or has been stored for years and its current setup is not certain.
Do all 1993 Buick Regal sub-models use the same tire size?
No. The 1993 Buick Regal does not use one tire size across every sub-model. Custom and Limited models share 205/70R15 radial tires, but the Gran Sport uses a different fitment: 225/60R16 radial.
That means trim level is more than a naming detail when shopping for tires. A buyer who starts with the wrong sub-model can end up looking at the wrong wheel diameter, the wrong sidewall treatments, and the wrong product range, so trim confirmation should come before any decision about appearance or brand.
Choosing the Right Tire
What should I consider when choosing a 205/70R15 tire for a 1993 Buick Regal?
Start by confirming that the Regal is a Custom or Limited with 15-inch wheels, since 205/70R15 is the trim-specific fitment for those cars. Within that size, available choices include blackwall, narrow whitewall, and wide whitewall radials across several brands and tire series.
The right selection depends on how the car is used and how it should look. A whitewall can suit a more traditional Buick presentation, while blackwall choices may better match a cleaner modernized look, and rim-width compatibility is worth checking if the car has replacement wheels rather than its original 15-inch setup.
What sidewall styles are available for 1993 Buick Regal tires?
Sidewall choices for the 1993 Buick Regal vary by tire size. In 205/70R15, available styles include blackwall, narrow whitewall, and wide whitewall. In 225/60R16, choices expand to raised yellow letter, redline, pin-white-stripe, wide whitewall, and narrow whitewall.
That variety lets the tire shape the car’s visual character as much as its fitment. A Gran Sport can take on a more performance-oriented look with raised yellow letter or redline styling, while a Custom or Limited may suit a more formal whitewall treatment, provided the tire size still matches the correct wheel diameter.
What brands offer tires for the 1993 Buick Regal?
Tires for the 1993 Buick Regal are available from several brands, depending on size. The 205/70R15 fitment includes Maxxis, Michelin, Avon, American Classic, Coker Classic, Dunlop, Tornel, and Travelstar, while the 225/60R16 fitment includes Goodyear, BFGoodrich, and Travelstar.
Brand should be compared alongside size, wheel compatibility, and appearance rather than in isolation. Once the correct Regal trim and wheel diameter are confirmed, the buyer can narrow the field by preferred sidewall style, tire series character, and any practical details such as rim-width range or load figures that apply to the intended use.
Restoration & Appearance
Which tire should I choose for a period-style 1993 Buick Regal?
A period-style 1993 Buick Regal tire choice starts with the correct trim-specific size: 205/70R15 for Custom and Limited, or 225/60R16 for Gran Sport. From there, the appearance can be tuned through available blackwall, whitewall, redline, pin-white-stripe, or raised yellow letter options, depending on the wheel package.
The most convincing look usually comes from matching the tire’s sidewall treatment to the character of the car rather than choosing by size alone. A formal Regal often benefits from a whitewall presentation, while a sportier Gran Sport may suit redline or lettered sidewalls, though exact originality should be checked against Buick-specific historical references.
How does tire construction affect the appearance of a restored 1993 Buick Regal?
The primary tire fitments for the 1993 Buick Regal are radial, so the construction itself aligns with the era of the car. Appearance is shaped less by a bias-ply-versus-radial decision and more by sidewall treatment, tire series styling, and whether the car carries 15-inch or 16-inch wheels.
That makes visual details especially important on a restored Regal. A narrow or wide whitewall can reinforce Buick’s upscale character, while redline or raised yellow letter styling changes the mood substantially, so the tire should be chosen as part of the overall restoration theme rather than as a purely mechanical replacement.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1993 Buick Regal?
Yes. Modifications can change tire fitment on a 1993 Buick Regal even when the car started with a correct factory-size combination. Aftermarket wheels, altered wheel width, suspension changes, or body and brake upgrades can all affect which tire size and rim combination works safely.
That is especially important on a Regal that no longer carries its original 15-inch or 16-inch wheels. Before installing tires, verify wheel diameter, wheel width, and available clearance at the fender, suspension, and steering components so the chosen tire matches the actual setup rather than only the original sub-model specification.
What should I inspect before driving a 1993 Buick Regal on new tires?
Before driving a 1993 Buick Regal on new tires, inspect the wheels for damage, confirm lug hardware condition, and make sure the tire size matches both the sub-model and the wheel diameter. It is also wise to check alignment-related wear patterns if the old tires came off unevenly.
A road-ready inspection should also include proper inflation, valve condition, brake function, and a quick look at suspension and steering parts that can affect how the new tires behave. On a low-use Regal, stale fuel, aged rubber components, and long-storage flat spotting elsewhere on the car deserve attention before extended driving.
How should tires on a collector-era 1993 Buick Regal be maintained?
Tires on a collector-era 1993 Buick Regal should be maintained with regular pressure checks, routine visual inspection, and periodic driving or repositioning to reduce long-term flat spotting. Sidewalls and tread should be watched for cracking, cuts, bulges, uneven wear, or slow air loss.
Storage conditions matter as much as mileage on a low-use Regal. Keeping the car away from prolonged sunlight, heat, moisture, and ozone sources helps preserve tire condition, and a fresh inspection before seasonal road use is smart even when tread depth still looks good and the car has not traveled many miles.
