The 1981 Pontiac Grand Prix came from an era when personal luxury coupes balanced formal styling with everyday road manners, making tire appearance and ride character an important part of the car’s overall presentation. On this exact model, the fitment question centers on two 14-inch radial sizes: 195/75R14 and 205/75R14. That keeps the construction choice straightforward, while still leaving room to choose among different whitewall treatments, a redline option, and several classic-style radial series. For a restoration-minded owner or a driver putting a well-kept Grand Prix back on the road, the key is confirming which size best matches the car’s wheel setup and intended look.
Which Tire Size Is Right for The 1981 Pontiac Grand Prix
The 1981 Pontiac Grand Prix uses two primary tire sizes, 195/75R14 and 205/75R14, and both are radial fitments for 14-inch wheels. Since the same two sizes appear across the covered sub-models, the first step is usually confirming which size is already on the car and whether the wheel width and overall stance support that choice. From there, the decision shifts to sidewall style, tire series, and the kind of period-style appearance you want.
The 195/75R14 size uses a modern metric radial format: 195 is the nominal section width in millimeters, 75 is the aspect ratio, R identifies radial construction, and 14 is the wheel diameter in inches. On a 1981 Pontiac Grand Prix, this size keeps the fitment in the radial family the car uses while giving a slightly narrower footprint than 205/75R14. Available choices include Coker Classic, Tornel, Maxxis, and Travelstar, with wide whitewall and narrow whitewall presentations across several series. It is a useful size to evaluate when wheel width, existing tire clearance, or a more restrained visual profile matters.
The 205/75R14 size follows the same metric radial convention, with a 205-millimeter nominal section width, a 75-series profile, radial construction, and a 14-inch rim diameter. For the 1981 Pontiac Grand Prix, it offers another primary 14-inch radial fitment and opens up the broadest assortment of available styles. This size is offered by American Classic, Coker Classic, Maxxis, Tornel, BFGoodrich, and Travelstar, with narrow whitewall, wide whitewall, and redline options across multiple radial series. It makes sense to consider when appearance variety is a priority and the car’s wheel setup supports the wider size.
Tire fitment stays consistent across the covered 1981 Pontiac Grand Prix sub-models, with the same two radial sizes appearing throughout the range. That makes sub-model identification less about finding a unique size and more about confirming the actual wheel setup on the car, especially if it has aluminum wheels or other changes from standard trim.

1981 Pontiac Grand Prix Base
The 1981 Pontiac Grand Prix Base uses the same pair of 14-inch radial size options found elsewhere in the model line. Tire selection usually comes down to confirming which size is on the car now, then choosing the sidewall style and tire series that best suit its road use and presentation.
The 1981 Pontiac Grand Prix Brougham shares the same 14-inch radial fitment pattern as the other covered sub-models. That leaves room to focus on whether a narrower or wider primary size better matches the car’s wheels, along with whether a whitewall or redline look fits the overall character you want.
1981 Pontiac Grand Prix Brougham w/aluminum wheels
The 1981 Pontiac Grand Prix Brougham w/aluminum wheels uses the same primary radial size choices as the rest of the lineup. Since wheel material does not change the basic size listing here, the practical step is verifying the actual wheel width before settling on either the 195/75R14 or 205/75R14 option.
The 1981 Pontiac Grand Prix LJ follows the same two-size, 14-inch radial fitment approach as the other sub-models. That makes tire choice more about the finished look of the car and the details of the available radial series than about hunting for a trim-specific tire size.
The 1981 Pontiac Grand Prix LJ w/aluminum wheels still uses the same primary radial size options as the standard LJ. Checking the actual wheels on the car remains important, especially if they have been changed over time, because wheel width can influence which of the two supported sizes makes the most sense.
The 1981 Pontiac Grand Prix w/aluminum wheels shares the same 195/75R14 and 205/75R14 radial fitment choices as the other covered versions. For selection, the more important question is how the current wheel package, tire appearance, and intended use line up with the size and sidewall style you choose.
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.

Tire Size & Fitment
What tire size fits a 1981 Pontiac Grand Prix?
A 1981 Pontiac Grand Prix uses either 195/75R14 or 205/75R14, and both are radial tire sizes for a 14-inch wheel. Those two sizes appear across the covered Grand Prix sub-models, including Base, Brougham, LJ, and versions with aluminum wheels, so the fitment range is straightforward even though there are two supported sizes.
The practical choice is determining which size matches the wheels currently on the car and the look you want. Since both sizes share the same 14-inch rim diameter but differ in section width and overall diameter, it helps to confirm wheel width, compare the size already installed, and check body and steering clearance before changing from one supported size to the other.
What size rim does a 1981 Pontiac Grand Prix use?
The supported tire sizes for a 1981 Pontiac Grand Prix both use a 14-inch rim diameter. That means 195/75R14 and 205/75R14 are both built for 14-inch wheels, which keeps the basic diameter question simple across the covered sub-model lineup.
Rim diameter is only part of the fitment picture, so it is still worth checking the wheel itself before ordering tires. A Grand Prix may still have its original-style wheels, aluminum wheels, or later replacements, and wheel width can influence which of the two supported radial sizes is the better match for the car’s current setup and intended appearance.
Do all 1981 Pontiac Grand Prix sub-models use the same tire size?
The covered 1981 Pontiac Grand Prix sub-models share the same two tire size options: 195/75R14 and 205/75R14. That includes Base, Brougham, Brougham w/aluminum wheels, LJ, LJ w/aluminum wheels, and Grand Prix w/aluminum wheels, all using radial construction on 14-inch rims.
Shared size coverage makes shopping easier, but it does not mean every individual car should automatically switch between the two sizes without a closer look. The best next step is to inspect the tires and wheels already on the vehicle, verify wheel width, and decide whether the goal is to preserve the current stance or move toward a different whitewall or redline presentation.
Choosing the Right Tire
What should I consider when choosing a 1981 Pontiac Grand Prix tire?
Start with the correct primary size for the car as equipped, which means choosing between 195/75R14 and 205/75R14 on a 14-inch wheel. Both are radial sizes, so the main buying factors become wheel compatibility, sidewall appearance, tire series, and whether the car is being kept as a road car, a restoration project, or a more appearance-focused cruiser.
It helps to compare the tire already on the car, especially if the Grand Prix has replacement wheels or has changed hands several times. Once the size is settled, focus on the visual character you want, such as narrow whitewall, wide whitewall, or redline, along with practical details like rim-width suitability and the load figures attached to specific product options.
What sidewall styles are available for 1981 Pontiac Grand Prix tires?
Tires for a 1981 Pontiac Grand Prix are available with several sidewall styles, including narrow whitewall, wide whitewall, and redline. Those styles appear primarily in the 205/75R14 offerings, while 195/75R14 choices center on narrow whitewall and wide whitewall options.
That variety means the tire can noticeably change the car’s personality even when the size stays correct. A wide whitewall can lean toward a more formal, luxury-oriented presentation, while a narrow whitewall or redline can create a different period-style look, so the right choice often depends on how the Grand Prix is finished and how closely the owner wants the tires to complement it.
What brands offer tires for the 1981 Pontiac Grand Prix?
Available brands for the 1981 Pontiac Grand Prix include Coker Classic, American Classic, BFGoodrich, Maxxis, Tornel, and Travelstar, depending on size and sidewall style. The 205/75R14 size has the broadest spread of brand and appearance choices, while 195/75R14 still offers several classic-style radial options.
Brand selection matters most when it changes the sidewall treatment, tire series, or wheel-compatibility details that fit your needs. Rather than chasing a name alone, compare the exact size, whitewall or redline presentation, and any useful specification differences such as rim-width guidance or load figures, then choose the tire that matches the Grand Prix’s setup and intended use.
Restoration & Appearance
Which tire should I choose for a period-style 1981 Pontiac Grand Prix?
A period-style 1981 Pontiac Grand Prix tire choice usually starts with staying in one of the two supported 14-inch radial sizes, 195/75R14 or 205/75R14, then selecting the sidewall presentation that best suits the car. Whitewall options are available in both narrow and wider formats, and 205/75R14 also opens the door to a redline treatment.
The right answer depends on the specific personality of the car rather than a one-size-fits-all restoration rule. Owners who want a formal personal-luxury look often focus on whitewall styles, while others may prefer a sportier period-style impression, and exact originality should be checked against marque references, old photos, or build-specific documentation if that level of detail matters.
How does tire construction affect the appearance of a restored 1981 Pontiac Grand Prix?
On a 1981 Pontiac Grand Prix, construction does not create a bias-ply-versus-radial decision because the primary fitments are already radial. Appearance changes instead come more from the tire’s sidewall design, size choice, and series styling than from switching between fundamentally different construction types.
That still makes construction worth understanding, because a classic-style radial can preserve a more appropriate visual feel than a generic modern tire. Choosing between 195/75R14 and 205/75R14, then pairing that size with a narrow whitewall, wide whitewall, or redline sidewall, has a bigger effect on a restored Grand Prix’s finished look than the radial construction alone.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1981 Pontiac Grand Prix?
Yes, modifications can affect tire fitment on a 1981 Pontiac Grand Prix even when the car is using one of the supported sizes. Aftermarket wheels, suspension changes, ride-height adjustments, brake conversions, or bodywork changes can alter the space available for a 195/75R14 or 205/75R14 tire and may also change which wheel widths make sense.
That is why the tire size on paper should be matched against the actual car in front of you. A Grand Prix with non-original wheels may still use the correct 14-inch diameter but need closer attention to wheel width, inner clearance, and fender room, especially when moving from the narrower 195 size to the wider 205 size.
What should I inspect before driving a 1981 Pontiac Grand Prix on new tires?
Before putting a 1981 Pontiac Grand Prix back on the road with new tires, inspect the wheels for damage, make sure the tire size matches the wheel diameter, and verify that the old tires did not hide rubbing or suspension issues. It is also wise to check steering components, shocks, and basic alignment condition so the new radial tires are not asked to compensate for worn chassis parts.
A road test is more meaningful when the car starts with the right air pressure and clean, dry valve areas that can be checked for leaks afterward. Collector cars that sit for long periods deserve extra attention to wheel corrosion, brake drag, and uneven tire wear patterns, since those issues often appear before a longer drive.
How should 195/75R14 or 205/75R14 tires on a collector 1981 Pontiac Grand Prix be maintained?
Maintain 195/75R14 or 205/75R14 tires on a collector 1981 Pontiac Grand Prix by checking inflation regularly, inspecting tread and sidewalls for cracking, cuts, bulges, or air loss, and watching for uneven wear that can point to alignment or suspension issues. Low-mileage collector cars often age tires by time and storage conditions rather than by tread wear alone.
Good storage habits matter just as much as routine inspection. Keeping the Grand Prix away from prolonged sunlight, standing moisture, and ozone sources can help preserve the tires’ condition, and occasional movement helps avoid long-term flat spotting. Any car returning to regular road use should have its tires reviewed closely, even if the tread still looks serviceable.
