The 1981 Pontiac Grand LeMans came from a period when traditional rear-wheel-drive Pontiacs still balanced family-car practicality with distinctly American proportions and trim. Buyers today often approach this model from two different directions: preserving a clean survivor-style sedan or coupe, or sorting out a Safari wagon that carries a different wheel-and-tire look altogether. Tire fitment on the 1981 Pontiac Grand LeMans is radial, with 185/75R14, 195/75R14, and 225/75R15 sizes depending on the sub-model. That creates meaningful choices in whitewall width, brand, and tire series. The key is matching the exact sub-model and wheel diameter before deciding on appearance and road-use priorities.
Which Tire Size Is Right for The 1981 Pontiac Grand LeMans
Three tire sizes apply to the 1981 Pontiac Grand LeMans, and the right choice depends first on identifying the exact sub-model and confirming whether the car uses a 14-inch or 15-inch wheel. The 6 Cyl. versions can use either 185/75R14 or 195/75R14, the 8 Cyl. uses 195/75R14, and the Safari uses 225/75R15. Once that is settled, the decision shifts to whitewall treatment, brand, tire series, and wheel-width compatibility within the correct size.
185/75R14 is a metric radial size in which 185 identifies nominal section width in millimeters, 75 is the aspect ratio, R marks radial construction, and 14 is the wheel diameter in inches. On the 1981 Pontiac Grand LeMans, this size is used on certain 6 Cyl. applications and reflects a modern radial fitment rather than an older bias-ply format. Available choices center on narrow whitewall presentations from Tornel, Maxxis, and Travelstar across series such as Tornel Classic, Classic Whitewall MA-1, and UN106. It is a useful size to evaluate when keeping the correct 14-inch setup and a modest traditional sidewall look matters.
195/75R14 uses the same modern metric radial format, with a 195-millimeter nominal section width, a 75-series profile, radial construction, and a 14-inch rim. This size serves both the 1981 Pontiac Grand LeMans 8 Cyl. and some 6 Cyl. versions, making it one of the core fitments for the model line. Product choices include wide whitewall and narrow whitewall styles from Coker Classic, Tornel, Maxxis, and Travelstar, with series such as Star Series, Coker Classic Radial, Tornel Classic, Classic Whitewall MA-1, and UN106. It is the size to focus on when the car retains 14-inch wheels and the buyer wants the broadest appearance and brand selection.
225/75R15 is a larger metric radial size, with 225 denoting nominal section width in millimeters, 75 indicating the aspect ratio, R for radial construction, and 15 for rim diameter. On the 1981 Pontiac Grand LeMans, this size belongs to the Safari, so it should not be assumed across the rest of the model range. Available options span narrow and wide whitewall styles from BFGoodrich, Coker Classic, American Classic, Maxxis, and Travelstar, including Silvertown Radial, Star Series, American Classic Radial, and UN106 lines. It is the right starting point when the vehicle is a Safari with 15-inch wheels and a larger wagon-style tire profile.
Sub-model fitment matters on the 1981 Pontiac Grand LeMans because tire size is not the same across the full range. The first step is confirming whether the car is a 6 Cyl., 8 Cyl., or Safari and then matching that to the wheel diameter already on the vehicle.

1981 Pontiac Grand LeMans 6 Cyl.
The 1981 Pontiac Grand LeMans 6 Cyl. can use either 185/75R14 or 195/75R14 radial tires on 14-inch wheels. That makes wheel confirmation especially important, after which the choice usually comes down to whitewall width, brand, and series within the correct size.
The 1981 Pontiac Grand LeMans 8 Cyl. uses the 195/75R14 radial size on a 14-inch wheel. Tire selection is more straightforward here, with the main decision shifting toward narrow versus wide whitewall appearance and comparison among the available radial product lines.
The 1981 Pontiac Grand LeMans Safari uses the larger 225/75R15 radial size on a 15-inch wheel. That means the first priority is keeping the Safari's wheel diameter and size category straight before comparing the available narrow whitewall and wide whitewall options.
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 1981 Pontiac Grand LeMans Tires for Sale
Available 1981 Pontiac Grand LeMans tire options are all radial and vary meaningfully by size, brand, tire series, and whitewall treatment. Buyers can compare offerings from Tornel, Maxxis, Travelstar, Coker Classic, BFGoodrich, and American Classic across narrow and wide whitewall styles.
These FAQs focus on the exact tire sizes used on the 1981 Pontiac Grand LeMans, how fitment changes by sub-model, and how to sort through wheel diameter, whitewall style, brand, and general road-use checks before driving.
Tire Size & Fitment
What tire size fits a 1981 Pontiac Grand LeMans?
The 1981 Pontiac Grand LeMans uses three radial tire sizes depending on the sub-model: 185/75R14, 195/75R14, and 225/75R15. The 6 Cyl. can use 185/75R14 or 195/75R14, the 8 Cyl. uses 195/75R14, and the Safari uses 225/75R15.
That means the right starting point is identifying the exact sub-model and then confirming the wheel diameter already on the car. A 14-inch Grand LeMans sedan or coupe should not be treated the same as a 15-inch Safari, and a 6 Cyl. car needs extra attention because two different 14-inch sizes are associated with it.
What size rim does a 1981 Pontiac Grand LeMans use?
A 1981 Pontiac Grand LeMans uses either a 14-inch or 15-inch rim, depending on the sub-model and tire size. The 185/75R14 and 195/75R14 sizes are built for 14-inch wheels, while the 225/75R15 size is built for a 15-inch wheel.
Wheel diameter needs to be verified before comparing tires, because the Grand LeMans range does not stay on one rim size across every version. Checking the stamping on the wheel, the existing tire size, and the actual sub-model will help prevent ordering a tire that matches the car's nameplate but not the wheel on the vehicle.
Why does the 1981 Pontiac Grand LeMans have more than one tire size?
The 1981 Pontiac Grand LeMans has more than one tire size because fitment changes by sub-model. The 6 Cyl. applications use 14-inch radial sizes, the 8 Cyl. uses 195/75R14, and the Safari moves to a 225/75R15 radial on a 15-inch wheel.
That variation means tire selection is tied to configuration rather than just year and model name. A buyer should verify whether the vehicle is a 6 Cyl., 8 Cyl., or Safari, then confirm the actual wheel diameter and existing setup, especially if the car has had wheel changes or has been off the road long enough for past substitutions to blur the original fitment.
Choosing the Right Tire
What should I consider when choosing a tire for a 1981 Pontiac Grand LeMans?
Start with the correct tire size for the exact 1981 Pontiac Grand LeMans sub-model, then narrow the choice by wheel diameter, whitewall style, and the character of the available radial tire lines. A 6 Cyl. may use 185/75R14 or 195/75R14, the 8 Cyl. uses 195/75R14, and the Safari uses 225/75R15.
After size is settled, compare how the tire will look on the car and whether its wheel-width specification suits the wheels already installed. Some buyers want a wider whitewall for a more traditional presentation, while others prefer a narrower stripe, so the final choice often comes down to appearance, wheel compatibility, and the way the car is actually used.
What sidewall styles are available for 1981 Pontiac Grand LeMans tires?
Whitewall styling is the main sidewall choice for 1981 Pontiac Grand LeMans tires, with both narrow whitewall and wide whitewall options depending on the size selected. The 185/75R14 choices center on narrow whitewalls, while 195/75R14 and 225/75R15 include both narrow and wider whitewall treatments.
That gives the buyer room to tune the car's presentation without leaving the correct size category. A narrower whitewall tends to keep the look restrained, while a wider whitewall creates a more pronounced period-style appearance, so it helps to decide early whether the goal is a subtle survivor look or a more formal restoration-oriented visual statement.
What brands offer tires for the 1981 Pontiac Grand LeMans?
Tires for the 1981 Pontiac Grand LeMans are available from Tornel, Maxxis, Travelstar, Coker Classic, BFGoodrich, and American Classic, depending on size. Brand availability changes with fitment, so the 14-inch sizes and the 225/75R15 Safari size do not all share the same product mix.
Brand matters mainly as part of a larger comparison that includes tire series, whitewall width, and wheel-width compatibility. It is more useful to begin with the exact size and sub-model, then compare the brands that exist within that fitment rather than choosing a brand first and trying to force it onto a size or wheel setup that does not match the car.
Restoration & Appearance
Which tire should I choose for a period-style 1981 Pontiac Grand LeMans?
A period-style 1981 Pontiac Grand LeMans tire choice starts with the correct radial size for the exact sub-model, then moves to sidewall presentation. The main visual distinction across the available options is narrow whitewall versus wide whitewall, with 195/75R14 and 225/75R15 offering the broadest appearance choices.
That approach keeps the tire grounded in proper fitment instead of treating appearance as a separate decision. If originality matters at a finer historical level, it is worth checking marque references or surviving vehicle documentation, but for most restoration-oriented buyers the practical balance is correct size first, then a whitewall style that suits the car's trim and stance.
How does tire construction affect the appearance of a restored 1981 Pontiac Grand LeMans?
Tire construction is straightforward on the 1981 Pontiac Grand LeMans because the applicable fitments here are radial. The visual difference in a restored car therefore comes less from bias-ply versus radial and more from the tire's section, profile, and whitewall treatment within the correct 14-inch or 15-inch size.
That makes size discipline especially important during a cosmetic restoration. A Grand LeMans can look noticeably different if a Safari-size tire is confused with a sedan fitment, or if a wide whitewall is chosen where a narrower stripe better matches the car's overall presentation, so appearance and fitment should be evaluated together rather than separately.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1981 Pontiac Grand LeMans?
Yes, modifications can affect tire fitment on a 1981 Pontiac Grand LeMans even when the tire size itself is correct for the model range. Aftermarket wheels, changes in wheel width, altered offset, suspension work, or ride-height changes can all influence how a 14-inch or 15-inch tire sits in the car.
That is especially important on a model with more than one factory size and more than one rim diameter. A buyer should confirm the actual wheel dimensions on the vehicle, then check steering, fender, and suspension clearance at full travel and lock, rather than assuming the nameplate alone tells the whole tire story.
What should I inspect before driving a 1981 Pontiac Grand LeMans on new tires?
Before driving a 1981 Pontiac Grand LeMans on new tires, inspect the wheels, valve stems, lug hardware, and overall clearance around the tire. It also helps to confirm that the installed size matches the sub-model and wheel diameter, since this car can use either 14-inch or 15-inch fitments depending on configuration.
A sensible first road check includes tire pressure, any signs of rubbing, and a look at suspension and steering condition if the car has been stored for long periods. Collector-era cars often sit longer than daily drivers, so a short initial drive followed by another inspection can catch contact marks, air loss, or settling issues early.
How should tires on a collector 1981 Pontiac Grand LeMans be maintained?
Tires on a collector 1981 Pontiac Grand LeMans should be maintained with regular pressure checks, periodic visual inspections, and attention to age-related condition as well as tread. Even a low-mile car can develop cracking, flat spotting, air loss, or sidewall damage if it spends long periods parked.
Storage conditions matter almost as much as mileage on a vehicle of this age. Keeping the car away from prolonged sunlight, excess heat, moisture, and ozone sources can help preserve the tires, and occasional movement helps prevent one section of the carcass from carrying the vehicle's weight in the same spot for too long.
