The 1997 Buick Regal sits in the era when Buick blended traditional midsize comfort with a more modern front-wheel-drive platform and sharper trim distinctions. Buyers looking at one today are often balancing preserved original character with dependable road manners for regular cruising. Tire fitment on the 1997 Buick Regal centers on two radial sizes, 205/70R15 and 225/60R16, with the correct choice tied directly to the sub-model and wheel diameter. Within those sizes, there is meaningful variety in brands, sidewall styles, and tire series. The right selection starts with confirming whether the car wears the 15-inch or 16-inch setup, then choosing the appearance and road-use style that suits the car.
Which Tire Size Is Right for The 1997 Buick Regal
The 1997 Buick Regal uses two primary tire sizes, and the first step is identifying the exact sub-model and wheel diameter. One setup uses a 15-inch rim with 205/70R15 tires, while the other uses a 16-inch rim with 225/60R16 tires. Because both are radial fitments, the main decision is not bias-ply versus radial, but selecting the correct size first and then comparing sidewall style, brand, and tire series within that fitment.
205/70R15 is a metric radial size in which 205 is the nominal section width in millimeters, 70 is the aspect ratio, R identifies radial construction, and 15 is the wheel diameter in inches. On the 1997 Buick Regal, this size belongs on the 15-inch wheel setup used by specific sub-models. Available choices include blackwall, narrow whitewall, and wide whitewall tires from brands such as Maxxis, Michelin, Avon, American Classic, Coker Classic, Dunlop, Tornel, and Travelstar. This size is the right place to focus if your Regal carries the 15-inch arrangement and you want to match either a more traditional Buick look or a cleaner blackwall presentation.
225/60R16 is a metric radial size where 225 states the nominal section width in millimeters, 60 is the aspect ratio, R marks radial construction, and 16 is the required wheel diameter in inches. On the 1997 Buick Regal, this size is tied to the 16-inch setup used on a specific sub-model rather than the full range. Product choices include raised yellow letter, redline, pin-white-stripe, narrow whitewall, and wide whitewall styles from Goodyear, BFGoodrich, and Travelstar. This size deserves a close look if your Regal is equipped with 16-inch wheels and you want a more performance-leaning profile with several distinct appearance treatments.
Sub-model fitment matters on the 1997 Buick Regal because tire size is not shared across the full lineup. Confirming whether the car is a GS, GS Gran Touring, or LS is the quickest way to avoid choosing the wrong rim diameter and tire size.

1997 Buick Regal GS
The 1997 Buick Regal GS uses the 205/70R15 radial setup on a 15-inch wheel. Tire selection here is mainly about choosing the right radial within that size, with options that range from blackwall to whitewall styling depending on whether the goal is a more understated or more traditional Buick presentation.
The 1997 Buick Regal GS Gran Touring uses the 225/60R16 radial size on a 16-inch wheel. That makes wheel confirmation especially important, and it also opens the door to several appearance choices such as raised yellow letter, redline, pin-white-stripe, whitewall, and blackwall-free performance-style alternatives.
The 1997 Buick Regal LS uses the 205/70R15 radial fitment on a 15-inch wheel. Once that size is confirmed, the decision usually comes down to brand, sidewall treatment, and whether the car is being kept in a more restoration-oriented style or driven with a simpler modern radial look.
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.

These FAQs focus on the exact tire sizes used on the 1997 Buick Regal, how fitment changes by sub-model, and how to sort through rim diameter, sidewall style, brand, and road-use considerations before choosing a tire.
Tire Size & Fitment
What tire size fits a 1997 Buick Regal?
A 1997 Buick Regal uses either 205/70R15 or 225/60R16 tires, depending on the sub-model and wheel setup. The GS and LS use 205/70R15 radial tires on 15-inch rims, while the GS Gran Touring uses 225/60R16 radial tires on 16-inch rims.
That means the correct starting point is not just the model name, but the exact sub-model and the wheel diameter currently on the car. A Regal that has been changed over to different wheels at some point should be measured and confirmed before any tire is selected, since the 15-inch and 16-inch fitments are not the same.
What size rim does a 1997 Buick Regal use?
The 1997 Buick Regal uses either a 15-inch or 16-inch rim, depending on the sub-model. The 205/70R15 fitment is built around a 15-inch wheel, and the 225/60R16 fitment is built around a 16-inch wheel.
Wheel diameter needs to be verified before looking at tread style or sidewall appearance, because a 15-inch tire cannot mount on a 16-inch rim and vice versa. It is also smart to confirm wheel width, especially if the car has aftermarket wheels, since several available tires in these sizes carry different rim-width recommendations.
Do all 1997 Buick Regal sub-models use the same tire size?
No. The 1997 Buick Regal lineup uses more than one tire size. The GS and LS use 205/70R15, while the GS Gran Touring uses 225/60R16, so tire fitment changes with the sub-model.
That difference matters because the two sizes also use different wheel diameters and create different buying choices in the product range. A quick check of the sub-model badge and the actual wheel on the car usually settles the question, but any Regal with replacement wheels should be inspected carefully before ordering tires by model name alone.
Choosing the Right Tire
What should I consider when choosing a tire for a 1997 Buick Regal?
Start with the correct tire size for the exact Regal sub-model: 205/70R15 for the GS and LS, or 225/60R16 for the GS Gran Touring. From there, compare radial construction details such as rim-width suitability, load figures where stated, brand, tire series, and the sidewall style that best matches the look you want.
Some owners want a cleaner blackwall tire, while others prefer whitewalls, a pin stripe, a redline, or raised yellow lettering for a stronger period feel. The best choice depends on whether the car is being preserved with a traditional Buick appearance, driven regularly, or set up with a more individual style than a plain replacement tire provides.
What sidewall styles are available for 1997 Buick Regal tires?
Sidewall choices for the 1997 Buick Regal include blackwall, narrow whitewall, wide whitewall, redline, pin-white-stripe, and raised yellow letter, depending on tire size. The 205/70R15 fitment includes blackwall, narrow whitewall, and wide whitewall options, while 225/60R16 adds redline, pin-white-stripe, wide whitewall, narrow whitewall, and raised yellow letter styles.
That variety lets the tire change the car’s visual character even when the size stays correct. A whitewall can give the Regal a more traditional Buick look, while redline or raised yellow letter sidewalls create a stronger enthusiast-oriented presentation. The practical first step is matching the sidewall choice to the proper size and wheel diameter for the specific sub-model.
What brands offer tires for the 1997 Buick Regal?
Tires for the 1997 Buick Regal are available from Maxxis, Michelin, Avon, American Classic, Coker Classic, Dunlop, Tornel, Travelstar, Goodyear, and BFGoodrich, depending on the size. Brand availability changes between the 205/70R15 and 225/60R16 fitments, so not every brand appears in both sizes.
Brand is only one part of the decision. It still makes sense to compare the tire series, sidewall treatment, and wheel-width suitability inside the correct size before deciding what belongs on the car. A Regal kept close to stock visual character may call for a different tire presentation than one being driven more casually or personalized in appearance.
Restoration & Appearance
Which tire should I choose for a period-style 1997 Buick Regal?
A period-style choice for a 1997 Buick Regal starts with the correct size for the sub-model, then moves to the sidewall look that best matches the car’s era and presentation. In 205/70R15 and 225/60R16, there are radial options with blackwall, narrow whitewall, wide whitewall, pin-white-stripe, redline, and raised yellow letter styling.
For a more formal Buick appearance, whitewall treatments often suit the Regal’s late-1990s character well, while blackwall keeps the look understated. Owners seeking exact restoration detail should compare the tire choice with original vehicle literature, marque-club references, or long-term ownership history, since a period-style tire is not automatically the same thing as an exact original presentation.
Does correct tire fitment matter for a 1997 Buick Regal restoration?
Yes, correct tire fitment matters on a 1997 Buick Regal restoration because the wrong size can change both the car’s appearance and its relationship to the wheel opening. The Regal used two distinct radial sizes, and the correct one depends on whether the car is a GS, GS Gran Touring, or LS.
A restoration-minded owner should confirm the sub-model, wheel diameter, and the overall visual effect of the sidewall before settling on a tire. Even when a tire mounts correctly, the wrong sidewall style can make the car look out of character. Fitment accuracy is especially important on a car from this era because trim differences often shaped the intended appearance.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1997 Buick Regal?
Yes. Modifications can affect tire fitment on a 1997 Buick Regal even when the tire size itself is correct for the original sub-model. Aftermarket wheels, altered wheel width, suspension changes, lowering, or body modifications can all change how a 205/70R15 or 225/60R16 tire sits in the car.
A Regal with non-original wheels should have the actual rim diameter and width checked before choosing a tire. Clearance around the fenders, steering components, and suspension should also be inspected, especially at full lock and over suspension travel. That extra step helps avoid rubbing, mounting issues, or choosing a sidewall style that works visually but not physically.
What should I inspect before driving a 1997 Buick Regal on new tires?
Before driving a 1997 Buick Regal on new tires, inspect the wheels for correct diameter and condition, verify proper inflation, and make sure the tires were mounted in the correct size for the sub-model. It is also wise to check for clearance around the fenders, steering, and suspension once the car is back on the ground.
A collector or low-use Regal deserves a broader inspection as well. Look over the suspension, alignment, valve stems, and brake components, and make sure there are no signs of interference during turning or compression. A short test drive followed by a second visual check is a smart way to catch rubbing, air loss, or seating issues early.
How should tires on a collector 1997 Buick Regal be maintained?
Tires on a collector 1997 Buick Regal should be maintained with regular pressure checks, visual inspections, and occasional movement of the car so the tires are not left loaded in one position for long periods. Sidewall cracking, cuts, bulges, uneven tread wear, and slow air loss deserve attention even if the car is only driven sparingly.
Storage conditions matter just as much as mileage on a car from this era. Keeping the Regal away from prolonged sunlight, excess heat, moisture, and ozone-producing equipment can help preserve tire condition. Before a longer drive, inspect tread and sidewalls closely and confirm the tire size and wheel setup still match the car as it sits today.
