The 1991 Buick Reatta came at the end of Buick’s distinctive personal luxury coupe and convertible experiment, blending late-1980s electronic flair with a hand-built feel that still gives the car a loyal collector following. Its styling and road manners place it firmly in a modern-classic space where owners often balance originality with practical drivability. For tire fitment, the 1991 Buick Reatta uses a 215/60R16 radial on a 16-inch rim. That keeps the decision focused less on multiple factory sizes and more on choosing the right radial within the correct dimensions. For a Reatta that still sees road use, appearance, wheel compatibility, and overall condition all matter before replacement.
Which Tire Size Is Right for The 1991 Buick Reatta
The 1991 Buick Reatta uses one primary tire size: 215/60R16. It is a radial fitment on a 16-inch rim, and the same size is used on the covered Reatta sub-model. That means the main decision is not sorting through multiple original sizes, but choosing a tire in the correct dimensions and confirming the car still has its proper wheel setup if anything has been changed over the years.
A 215/60R16 tire is a metric radial size in which 215 indicates section width in millimeters, 60 is the aspect ratio, R identifies radial construction, and 16 is the wheel diameter in inches. On a 1991 Buick Reatta, this size supports the car’s original late-model radial fitment rather than an earlier bias-ply sizing system. The practical focus is staying with the correct overall size category and wheel diameter for the car. It is the size to evaluate when replacing aged tires, refreshing a driver, or confirming fitment on a Reatta with stock-type 16-inch wheels.
Tire fitment is straightforward for the covered 1991 Buick Reatta sub-model. The listed sub-model uses the same primary tire size, so the main check is confirming that the car still has the correct 16-inch wheel setup and has not been altered with a different wheel and tire package.

Frequently Asked Questions
These FAQs focus on 1991 Buick Reatta tire size, 16-inch rim fitment, choosing the right 215/60R16 radial, and the condition checks that matter before putting a low-use modern classic back on the road.
Tire Size & Fitment
What tire size fits a 1991 Buick Reatta?
The 1991 Buick Reatta uses a 215/60R16 tire size. This is a modern metric radial size, and it is the primary fitment for the covered Reatta application. The same size is also used on the listed 1991 Buick Reatta Base sub-model.
That makes the fitment question fairly simple, but it is still worth checking the car itself before replacement. A Reatta that has been fitted with aftermarket wheels or a different wheel package in the past may no longer match the original 16-inch setup, so wheel diameter and overall clearance should be confirmed before choosing a new tire.
What size rim does a 1991 Buick Reatta use?
The 1991 Buick Reatta uses a 16-inch rim with its 215/60R16 tire size. In that size code, the final 16 indicates the wheel diameter in inches, which is the wheel size the tire is designed to mount on.
Rim diameter is the first item to confirm before ordering tires, especially on a car that may have changed hands several times. Even when the tire size on the sidewall appears close, a mismatch in wheel diameter will prevent proper mounting, so the actual wheel on the car should always be checked rather than assumed.
Does the 1991 Buick Reatta Base use the same tire size?
Yes. The 1991 Buick Reatta Base uses the same 215/60R16 radial tire size as the covered 1991 Buick Reatta fitment. There is no alternate primary size shown for that sub-model within this application.
That consistency simplifies replacement, but it does not eliminate the need for a quick wheel and tire inspection. A Base model with non-original wheels, suspension changes, or long-stored tires should be checked for actual wheel diameter, condition, and clearance so the replacement tire choice matches the car as it sits today.
Choosing the Right Tire
What should I consider when choosing a 215/60R16 tire for a 1991 Buick Reatta?
Start with the correct size: 215/60R16 on a 16-inch wheel. Since the Reatta uses a radial fitment, the key decision is choosing a tire that stays within the proper dimensions for the car rather than trying to sort through multiple original tire sizes or older sizing systems.
Beyond size, look at how the car is used. A Reatta kept mainly for shows may call for a different visual presentation than one used regularly on the road, and any past wheel changes should be verified before purchase. Tire age, wheel condition, and suspension condition are also worth reviewing while the car is apart.
How do I choose between available 215/60R16 tires for a 1991 Buick Reatta?
The best way to compare 215/60R16 tires for a 1991 Buick Reatta is to stay centered on fitment first, then compare the tire’s overall character. Because this Reatta application uses one primary radial size, the comparison is usually about selecting the right tire type for the car’s current use and appearance goals.
A low-mile collector car and a frequently driven Reatta may not be chosen the same way. It helps to confirm that the wheel size is still correct, then compare how each tire suits the car’s intended road use, visual presentation, and maintenance condition rather than treating every 215/60R16 option as automatically equivalent.
What rim-fitment details should I compare when choosing 1991 Buick Reatta tires?
The most important rim-fitment detail is wheel diameter, since the 1991 Buick Reatta uses a 16-inch wheel with its 215/60R16 tire size. The tire must match that diameter, and the wheel itself should also be in sound condition before a new set of tires is mounted.
Wheel width and overall setup matter as well, especially if the car has aftermarket wheels or prior modifications. A tire may be the correct nominal size but still deserve a closer look if the wheel package is no longer stock, so checking wheel dimensions and nearby suspension or fender clearance is a smart final step.
Restoration & Appearance
Which tire should I choose for a period-style 1991 Buick Reatta?
For a period-style 1991 Buick Reatta, the starting point is the original-size 215/60R16 radial fitment. Since this is already a modern metric radial size, maintaining the correct dimensions usually does more for the car’s visual balance than chasing a different sizing format that does not belong to the Reatta’s era.
Appearance-minded buyers should compare tires with the car’s intended presentation in mind, whether that is a clean original-style street car or a preserved collector example. When exact authenticity matters, checking model-specific photos, sales literature, or marque references can help narrow down details that go beyond simple size and construction.
Does correct tire fitment matter for a 1991 Buick Reatta restoration?
Yes, correct tire fitment matters on a 1991 Buick Reatta restoration because the tire size affects both appearance and stance. Using the proper 215/60R16 radial helps preserve the proportions the car was designed around and keeps the wheel-and-tire package aligned with the Reatta’s original-era presentation.
Fitment also affects practical details once the car returns to the road. A Reatta with the wrong wheel diameter or an off-size replacement can create avoidable issues with clearance and overall look, so it is wise to confirm the wheel setup and inspect suspension condition before finalizing tires for a restoration project.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1991 Buick Reatta?
Yes. Modifications can affect tire fitment on a 1991 Buick Reatta even when the intended replacement size is the original 215/60R16. Changes such as aftermarket wheels, altered wheel width, suspension work, or ride-height changes can all influence how a tire sits in the wheel opening and how much clearance remains.
That is why the current car should be checked before ordering replacement tires. A Reatta that still has its stock-type 16-inch wheels is a more straightforward situation, while a modified example deserves a close look at wheel diameter, surrounding clearance, and overall condition so the chosen tire suits the setup already on the car.
What should I inspect before driving a 1991 Buick Reatta on new tires?
Before driving a 1991 Buick Reatta on new tires, inspect the wheels for damage, confirm the wheel diameter matches the 215/60R16 fitment, and make sure the tires are mounted and inflated properly. It is also smart to look over the suspension and steering for looseness that could affect how the new tires behave on the road.
A car that has spent long periods parked deserves extra attention. Collector vehicles can hide age-related problems such as dry cracking on old tires, air loss, or worn bushings that only become obvious once the car is moving again. A careful walk-around and a short test drive can reveal issues before a longer trip.
How should 215/60R16 tires on a collector 1991 Buick Reatta be maintained?
215/60R16 tires on a collector 1991 Buick Reatta should be kept properly inflated, inspected regularly, and protected from long periods of neglect. Even when tread wear looks minimal, a low-use collector car can still develop age-related tire issues that deserve attention before the next drive.
Storage conditions matter almost as much as mileage. Keeping the Reatta away from prolonged sunlight, excess heat, and moisture helps preserve tire condition, while periodic checks for cracking, bulges, cuts, and slow air loss help catch problems early. Tires on lightly used collector cars should be evaluated by condition, not tread depth alone.
