The 1991 Buick Skylark came from a period when Buick's compact front-wheel-drive models balanced everyday comfort with trim-specific styling and equipment. That matters when choosing tires, because this Skylark family does not rely on one universal fitment across the board. Depending on sub-model, the 1991 Buick Skylark uses 185/80R13, 185/75R14, or 215/60R14 radial tires. Available choices also split by presentation, from narrow and wide whitewalls to raised white letter styling on the Gran Sport size. The right selection starts with the exact sub-model and wheel diameter, then moves to the appearance and road-use character that best suits the car.
Which Tire Size Is Right for The 1991 Buick Skylark
Three primary tire sizes apply to the 1991 Buick Skylark, and they vary by sub-model and wheel diameter. Some versions use a 13-inch wheel, while others use a 14-inch wheel, so confirming both the exact trim and the wheel currently on the car comes first. Once that is settled, the decision shifts to choosing the right radial tire style and sidewall treatment for the way the car is equipped and presented.
185/75R14 is a metric radial size in which 185 identifies the nominal section width in millimeters, 75 is the aspect ratio, R marks radial construction, and 14 is the wheel diameter in inches. On the 1991 Buick Skylark, this size suits 14-inch wheel applications and serves as a standard-looking radial choice for several sub-models. Available options include Tornel, Maxxis, and Travelstar, with narrow whitewall styling across several tire series. It is the size to focus on when your Skylark carries the common 14-inch setup and you want a tire that preserves a traditional passenger-car appearance.
185/80R13 is a metric radial size with a 185-millimeter nominal section width, an 80-series profile, radial construction, and a 13-inch rim diameter. For the 1991 Buick Skylark, this size belongs to certain 13-inch wheel configurations, so wheel diameter needs to be confirmed before selection. Product choices range from narrow whitewall to wide whitewall styles, including offerings from Maxxis, BFGoodrich, and Coker Classic in distinct series. This size is especially relevant when the goal is to match a softer, more traditional sedan presentation on a Skylark that still uses its 13-inch wheels.
215/60R14 is a metric radial size where 215 represents nominal section width in millimeters, 60 is the aspect ratio, R indicates radial construction, and 14 is the rim diameter in inches. On the 1991 Buick Skylark, this size is tied to the sport-oriented Gran Sport configuration and carries a visibly different fitment approach from the narrower standard sizes. The available product uses BFGoodrich's Radial T/A series with raised white letter sidewalls, reinforcing that more performance-flavored look. This is the size to evaluate when the car has the Gran Sport wheel and tire package rather than the regular passenger-car setup.
Sub-model fitment matters on the 1991 Buick Skylark because tire size is not the same across the full range. The first step is identifying whether the car is a Base, Custom, Gran Sport, or Luxury Edition, then confirming whether it carries 13-inch or 14-inch wheels.

1991 Buick Skylark Base
The 1991 Buick Skylark Base can use either a 185/75R14 radial or a 185/80R13 radial, making wheel diameter especially important on this trim. Tire selection starts with confirming whether the car has 13-inch or 14-inch wheels, then choosing the preferred whitewall style and tire series within that correct size.
The 1991 Buick Skylark Custom uses the 185/75R14 radial size, keeping fitment more straightforward than the Base model. That lets the buying decision focus more on sidewall presentation, brand, and rim-width compatibility rather than sorting through multiple primary sizes.
The 1991 Buick Skylark Gran Sport uses the 215/60R14 radial size, which separates it clearly from the narrower standard Skylark fitments. Tire choice here centers on keeping the proper 14-inch sport-oriented size and confirming wheel compatibility before selecting the raised white letter radial option.
The 1991 Buick Skylark Luxury Edition uses the 185/75R14 radial size, sharing its basic fitment approach with other 14-inch Skylark variants. That makes it easier to compare available narrow whitewall choices and select a tire that suits the car's appearance and intended driving use.
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.
Best 1991 Buick Skylark Tires for Sale
Available 1991 Buick Skylark tires span three primary sizes and several distinct looks. Buyers can compare BFGoodrich, Maxxis, Tornel, Travelstar, and Coker Classic options by tire series, whitewall treatment or raised white letters, and the rim-width specifications attached to each size.
These 1991 Buick Skylark tire questions center on the issues that matter most with this car: matching the correct size to the right sub-model, confirming 13-inch versus 14-inch wheels, and choosing among available radial sidewall and series options.
Tire Size & Fitment
What tire size fits a 1991 Buick Skylark?
The 1991 Buick Skylark uses three primary tire sizes depending on sub-model and wheel setup: 185/80R13, 185/75R14, and 215/60R14. The Base model can use either 185/80R13 or 185/75R14, the Custom and Luxury Edition use 185/75R14, and the Gran Sport uses 215/60R14.
That means the right answer starts with the exact trim and the actual wheel diameter on the car. A Base model especially deserves a close look, since it may have either 13-inch or 14-inch wheels. Checking the current wheel, sidewall size marking, and overall vehicle setup helps prevent choosing the correct Skylark size for the wrong wheel.
What size rim does a 1991 Buick Skylark use?
A 1991 Buick Skylark uses either a 13-inch or 14-inch rim, depending on sub-model and tire size. The 185/80R13 size uses a 13-inch rim, while both 185/75R14 and 215/60R14 use a 14-inch rim. The Gran Sport stays with a 14-inch wheel, while the Base model may appear with either wheel diameter.
Wheel diameter should be confirmed before anything else, because a tire cannot be mounted across different rim diameters. It also helps to verify wheel width, especially if the car has replacement wheels. Looking at the wheel itself and comparing it to the tire size already on the car gives a much safer starting point than choosing by model name alone.
Why does the 1991 Buick Skylark have more than one tire size?
The 1991 Buick Skylark has more than one tire size because fitment changes across the model range. The Base model can use either 185/80R13 or 185/75R14, the Custom and Luxury Edition use 185/75R14, and the Gran Sport uses a different 215/60R14 setup. Those differences reflect wheel diameter and trim-specific tire presentation.
For a buyer, that means the model year and name are not enough by themselves. The exact sub-model matters, and the current wheel setup matters just as much on cars that may have been changed over time. A quick check of the trim, wheel diameter, and existing sidewall marking is usually the clearest way to narrow the correct Skylark fitment.
Choosing the Right Tire
What should I consider when choosing a tire for a 1991 Buick Skylark?
Start with the correct primary size for the exact 1991 Buick Skylark sub-model and wheel diameter. After that, compare the available radial choices by sidewall style, brand, tire series, rim-width specification, and load figures such as 1279@35 psi, 1290@35 psi, or 1,345 lbs @ 35psi where they apply to the size you need.
The best choice depends on how the car is presented and driven. A whitewall option suits a more traditional passenger-car look, while the Gran Sport's 215/60R14 raised white letter tire creates a different visual character. Matching the tire to the wheel, the trim level, and the car's intended use leads to a more appropriate result than choosing by appearance alone.
What sidewall styles are available for 1991 Buick Skylark tires?
Sidewall choices for the 1991 Buick Skylark include narrow whitewall, wide whitewall, and raised white letter styling, depending on tire size. The 185/75R14 options use narrow whitewalls, the 185/80R13 size is available in both narrow and wide whitewall treatments, and the 215/60R14 Gran Sport size is offered with raised white letters.
That variety lets the tire appearance follow the character of the car. A Base, Custom, or Luxury Edition may lean toward a more traditional whitewall presentation, while a Gran Sport looks more at home with its sportier lettered sidewall. Sidewall style should always be chosen after the correct size and wheel diameter have already been confirmed.
What brands offer tires for the 1991 Buick Skylark?
Tires for the 1991 Buick Skylark are available from Tornel, Maxxis, Travelstar, BFGoodrich, and Coker Classic, depending on the size. Brand choice changes with the fitment: 185/75R14 includes Tornel, Maxxis, and Travelstar; 185/80R13 includes Maxxis, BFGoodrich, and Coker Classic; and 215/60R14 is available from BFGoodrich.
Brand alone should not be the first filter. It is more useful to start with the exact size, then compare the tire series and sidewall treatment available within that fitment. That approach keeps the search grounded in the needs of the specific Skylark configuration instead of overlooking a better visual or dimensional match in the correct size.
Restoration & Appearance
Which tire should I choose for a period-style 1991 Buick Skylark?
A period-style 1991 Buick Skylark tire starts with the correct original-format radial size for the exact sub-model and wheel diameter. For many Skylark trims that means 185/75R14 or 185/80R13 with a whitewall presentation, while the Gran Sport's 215/60R14 raised white letter tire creates a more performance-oriented early-1990s look.
Appearance should follow the trim level and the way the car is being restored or preserved. A narrow whitewall gives a restrained everyday Buick look, while a wide whitewall on 185/80R13 creates a dressier presentation. Buyers seeking exact historical authenticity should also compare the car against original literature or marque-specific references before settling on a sidewall style.
How does tire construction affect the appearance of a restored 1991 Buick Skylark?
On a restored 1991 Buick Skylark, construction is less of an appearance issue than sidewall style, because the primary fitments are already radial. The bigger visual difference comes from whether the car wears a narrow whitewall, a wide whitewall, or the raised white letter look used with the 215/60R14 Gran Sport fitment.
That means restoration-minded buyers should concentrate on size, wheel diameter, and sidewall presentation first. A properly sized radial with the right sidewall treatment will usually shape the car's visual stance more than the basic construction category. Keeping the proportions consistent with the trim and wheel setup helps the finished car look more cohesive from curbside to road use.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1991 Buick Skylark?
Modifications can absolutely affect tire fitment on a 1991 Buick Skylark. Aftermarket wheels, suspension changes, altered ride height, or body repairs can change the wheel width, offset, and the space available around the tire. That matters even more on a car like the Skylark, where both 13-inch and 14-inch wheel setups exist across the range.
A modified car should be checked at the wheel itself rather than selected by factory trim name alone. Tire size, rim diameter, and wheel width all need to agree before mounting. It is also smart to turn the steering through full travel and inspect fender and suspension clearance so the chosen tire matches the car's current setup, not just its original catalog fitment.
What should I inspect before driving a 1991 Buick Skylark on new tires?
Before driving a 1991 Buick Skylark on new tires, inspect the wheels for the correct diameter and condition, confirm the tire size matches the sub-model, and check that the tires are inflated properly for the application. It also helps to look over the valve stems, wheel balance, lug torque, and the tire's seated position on the rim.
A short visual inspection around the full tire is worthwhile after installation. Watch for sidewall contact, uneven spacing at the fender, or interference while turning the steering from lock to lock. Once the car is on the road, recheck pressure and look for any early signs of rubbing or air loss so the new set settles in without surprise fitment issues.
How should tires on a collector 1991 Buick Skylark be maintained?
Tires on a collector 1991 Buick Skylark should be kept clean, properly inflated, and inspected regularly even if the car is driven only occasionally. Long periods of storage can hide aging, flat spotting, air loss, or sidewall cracking. Tread depth matters, but condition and age matter just as much on a lower-use vehicle.
Storage habits make a real difference. Keeping the Skylark away from prolonged sunlight, excess heat, moisture, and ozone sources helps preserve the tires between drives. It is also wise to check pressures before every outing and give the tires a close look for bulges, cuts, or weathering, especially before any longer trip where a neglected issue could become more serious.
