1981 Buick Regal Tires

A 1981 Buick Regal uses 195/75R14 and 205/70R14 radial tire sizes. Both fitments use a 14-inch rim diameter, and the exact size can depend on the sub-model. Base, Limited, Limited w/aluminum wheels, and Regal w/aluminum wheels can use either size, while Regal Sport and Regal Sport w/aluminum wheels use 205/70R14.

That means the first step is matching the tire to the car's actual sub-model and current wheel setup rather than assuming every Regal used the same size. Since both sizes are close in overall proportions but not identical, it also helps to confirm what is already on the car before choosing a whitewall, redline, raised white letter, or blackwall replacement.

The 1981 Buick Regal uses a 14-inch rim diameter with both of its primary tire sizes, 195/75R14 and 205/70R14. The tire size itself confirms the wheel diameter in the last number, and the available Regal fitments stay consistent at 14 inches across the covered sub-models.

Rim diameter is only part of the picture, so the actual wheel on the car should still be checked before mounting a new set. If the Regal has aftermarket wheels, replacement aluminum wheels, or a changed suspension stance, wheel width and tire clearance become just as important as the 14-inch diameter when narrowing down the right tire.

No. Several 1981 Buick Regal sub-models can use either 195/75R14 or 205/70R14, but the Regal Sport and Regal Sport w/aluminum wheels use 205/70R14 only. All of these are radial fitments on 14-inch rims, yet the size choice is not completely uniform across the full Regal lineup.

That distinction matters because it changes the pool of available sidewall styles and tire series you can consider. A buyer working with a Sport model can focus directly on 205/70R14 options, while other Regal versions need one more verification step to confirm which of the two primary sizes matches the car's wheels and intended appearance.

Start with the correct primary size for the car, either 195/75R14 or 205/70R14, and confirm that the Regal's sub-model and wheel setup match that fitment. Since both are radial 14-inch sizes, the next decision usually shifts to appearance, tire series, and whether the car is meant to present more like a luxury coupe or a sportier personal car.

Once the size is settled, compare sidewall style, rim-width compatibility, load figures where shown, and the overall character of the tire. A whitewall can push the car toward a more formal period look, while redline, raised white letter, or blackwall options can change the Regal's personality without stepping outside its supported radial fitment range.

Sidewall choices for a 1981 Buick Regal include wide whitewall, narrow whitewall, redline, dual redline, raised white letter, and blackwall, depending on tire size. The 195/75R14 offerings focus on whitewall styles, while 205/70R14 opens the door to additional looks such as redline, dual redline, RWL, and blackwall.

That variety makes sidewall style one of the biggest visual decisions on this car. A Regal with formal trim or a restoration-oriented appearance may call for one of the whitewall options, while a Sport model or more aggressive period build may lean toward redline or raised white letter tires after the correct size has been confirmed.

Brands available for the 1981 Buick Regal include Coker Classic, Tornel, Maxxis, Travelstar, BFGoodrich, and Michelin. Brand selection depends on size, with 195/75R14 including Coker Classic, Tornel, Maxxis, and Travelstar, while 205/70R14 includes Maxxis, BFGoodrich, and Michelin.

Brand matters mainly because it shapes the available series and sidewall treatments rather than changing the basic fitment requirement. After matching the size to the Regal, compare each brand's visual style, rim-width specification where shown, and the kind of presentation the tire gives the car instead of choosing solely by name.

A period-style 1981 Buick Regal tire choice starts with the correct primary size for the sub-model, then moves to the visual tone you want the car to carry. Whitewall radials in 195/75R14 or 205/70R14 can suit a more formal Regal presentation, while 205/70R14 also offers redline, dual redline, raised white letter, and blackwall alternatives.

The right answer depends on whether the car is being restored, lightly customized, or simply kept true to the era's overall look. Exact originality is best checked against marque references, build paperwork, or surviving examples, but the supported Regal sizes give a solid starting point for creating a convincing early-1980s appearance.

Tire construction is less of a visual dividing line on a 1981 Buick Regal than it is on older collector cars because the primary Regal fitments are already radial. The bigger appearance difference comes from the sidewall treatment and tire series, especially when comparing wide whitewall, narrow whitewall, redline, raised white letter, and blackwall options.

That means a restored Regal usually benefits more from choosing the right size and sidewall style than from chasing a construction change. A formal coupe can look very different from a sport-oriented Regal even with the same wheel diameter, so the tire's profile and sidewall presentation deserve as much attention as the basic fitment itself.

Yes. A 1981 Buick Regal may have the correct original-size tire listed as 195/75R14 or 205/70R14, but modifications can still change whether a particular tire is appropriate for the car as it sits today. Aftermarket wheels, altered wheel width, changed offset, lowered suspension, or body and brake changes can all affect usable tire clearance.

That is why the actual wheel and chassis setup should be checked before choosing a replacement simply by size code. A Regal that has been modified may need closer attention to section width, steering sweep, and fender clearance, even when the tire still uses the correct 14-inch rim diameter shown for the model range.

Before driving a 1981 Buick Regal on new tires, inspect the wheels for damage, verify that the tire size matches the car, and make sure inflation is set appropriately for the tires being installed. It also helps to check valve stems, lug hardware, and overall wheel condition so the new tires are not mounted onto a questionable foundation.

A short test for clearance is smart as well, especially if the Regal has replacement wheels or suspension changes. Turn the steering through its range, listen for rubbing, and recheck air pressure after the first drive. On a collector-era car, fresh tires work best when the rest of the wheel, brake, and suspension system is also in sound condition.

1981 Buick Regal tires should be maintained with regular pressure checks, periodic visual inspection, and close attention to age and storage conditions. Even a lightly used collector car can develop cracking, flat spotting, air loss, or sidewall damage long before the tread looks worn out, especially if the car spends long stretches parked.

Routine maintenance should also include checking for uneven wear that might point to alignment or suspension issues. Keeping the Regal out of prolonged sunlight, excess moisture, and ozone sources helps preserve the tires between drives. Any sign of bulges, cuts, persistent vibration, or repeated pressure loss deserves immediate inspection before more road use.
