The 1991 Pontiac LeMans came at the close of the model's run, representing a practical compact car from an era when efficiency, easy drivability, and straightforward maintenance mattered more than excess. For owners keeping one on the road today, tire choice is less about sorting through multiple factory fitments and more about matching the car's original-sized road manners. This LeMans uses a 175/70R13 radial on a 13-inch rim. Available choices in that size lean toward a blackwall radial presentation, including the Avon CR6ZZ series. The key is selecting a tire that respects the car's compact proportions while confirming wheel condition, rim width, and overall fitment before regular road use.
Which Tire Size Is Right for The 1991 Pontiac LeMans
The 1991 Pontiac LeMans uses one primary tire size: 175/70R13, a radial fitted to a 13-inch rim. Both covered sub-models share that same basic fitment, so the decision is not which primary size applies, but which tire within that size makes the most sense for the car's intended use, appearance, and wheel setup.
The 175/70R13 size uses modern metric radial sizing: 175 is the nominal section width in millimeters, 70 is the aspect ratio, R identifies radial construction, and 13 is the wheel diameter in inches. On the 1991 Pontiac LeMans, that makes it a straightforward modern-style fitment rather than an older bias-ply or alphanumeric format. Available choices in this size include the Avon CR6ZZ with a blackwall sidewall and radial construction. It is the size to evaluate when keeping the car on its original wheel diameter and maintaining the compact proportions expected of the LeMans.
Tire fitment is simple across the covered 1991 Pontiac LeMans sub-models because both use the same primary size and radial construction. Checking the exact sub-model still helps confirm that the car retains its original wheel setup and has not been changed over the years.

1991 Pontiac LeMans LE
The 1991 Pontiac LeMans LE uses the same 175/70R13 radial fitment found across the covered range. That keeps tire selection focused on choosing the right product within the size and confirming the condition and dimensions of the existing 13-inch wheels.
The 1991 Pontiac LeMans Value Leader also uses the 175/70R13 radial size, so there is no separate sub-model-specific size decision to sort out. Tire choice comes down to selecting an appropriate radial in that size and verifying that the car still carries the correct wheel diameter and usable rim width.
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 1991 Pontiac LeMans?
The 1991 Pontiac LeMans uses a 175/70R13 radial tire. That size applies across the covered LE and Value Leader sub-models, so there is one primary fitment to focus on rather than several different factory-size paths.
That makes the main task verifying that the car still has its original 13-inch wheel setup and has not been altered with different wheels over time. Once wheel diameter is confirmed, the next step is comparing tire options within 175/70R13 for rim-width compatibility, intended road use, and the appearance you want on the car.
What size rim does a 1991 Pontiac LeMans use?
The 1991 Pontiac LeMans tire fitment centers on a 13-inch rim. Its primary tire size, 175/70R13, is built around that wheel diameter, so matching the tire to a true 13-inch wheel is essential before mounting anything.
Rim diameter is only part of the fitment picture, though. It is also smart to confirm the wheel's actual width, check for damage or corrosion on older rims, and make sure the car has not been changed to aftermarket wheels. Those details matter just as much as diameter when choosing a safe, usable tire in the correct size.
Do all 1991 Pontiac LeMans sub-models use the same tire size?
The covered 1991 Pontiac LeMans sub-models share the same tire size. Both the LE and the Value Leader use 175/70R13 radial tires, so there is no separate size split between those two versions.
That consistency simplifies tire shopping, but it still helps to confirm the exact wheel setup on the car in front of you. Compact cars like the LeMans are often altered with replacement wheels over time, and even when the sub-model fitment is shared, wheel width, wheel condition, and suspension changes can still affect which 175/70R13 tire makes the most sense.
Choosing the Right Tire
What should I consider when choosing a 175/70R13 tire for a 1991 Pontiac LeMans?
Start with the basics: correct size, radial construction, and 13-inch wheel compatibility. For the 1991 Pontiac LeMans, the right choice stays within 175/70R13 while also matching the wheel's actual width and the kind of driving the car will see.
After that, compare the details that shape day-to-day use and presentation. Rim-width range, load and speed specification, sidewall style, and tire series all matter when narrowing the field. On a lightly used survivor, appearance may matter as much as road feel, while a more regularly driven car benefits from close attention to wheel condition and overall tire age.
What sidewall styles are available for 1991 Pontiac LeMans tires?
Current 175/70R13 tire options for the 1991 Pontiac LeMans include a blackwall sidewall style. That gives the car a clean, understated appearance that suits a practical early-1990s compact without introducing a more overt vintage sidewall treatment.
Sidewall style does not change the basic fitment, but it does influence how the car presents once the wheels are mounted and on the ground. For an owner keeping a stock-looking LeMans, a blackwall can feel appropriately restrained. The more important checks remain size, wheel diameter, and whether the chosen tire's rim-width range matches the actual wheels on the car.
What brands offer tires for the 1991 Pontiac LeMans?
The available 175/70R13 fitment for the 1991 Pontiac LeMans includes Avon. In this size, the product offering centers on Avon’s CR6ZZ radial, giving owners a focused option rather than a broad spread of overlapping brand choices.
With a narrower product assortment, the comparison shifts away from brand ranking and toward specifications that affect real-world fitment. Check the wheel's width against the tire's approved range, confirm the 13-inch diameter, and think about how the car will be used. That approach is more useful than chasing brand variety for its own sake.
Restoration & Appearance
Which tire should I choose for a period-style 1991 Pontiac LeMans?
A period-style 1991 Pontiac LeMans starts with the correct 175/70R13 size on the proper 13-inch rim. Since this car uses a modern metric radial fitment, the visual goal is usually less about recreating a vintage bias-ply look and more about preserving the compact, understated stance the car was designed around.
That makes size discipline especially important. A tire that departs too far from the original format can change the visual balance of a small front-drive car quickly. Keeping the correct sizing format, using an appropriate blackwall presentation, and confirming the wheels have not been swapped are sensible first steps for a restoration-oriented LeMans.
Does correct tire fitment matter for a 1991 Pontiac LeMans restoration?
Correct tire fitment matters on a 1991 Pontiac LeMans restoration because the car's proportions are closely tied to its compact 175/70R13 radial setup. Using the proper size helps preserve the intended stance, wheel opening fill, and overall visual balance of the finished car.
It also keeps the restoration grounded in the way the car was meant to sit and drive, even if the project is more preservation-minded than concours-focused. Before settling on a tire, inspect the wheels for age and damage, confirm the 13-inch diameter, and make sure any previous owner changes have not altered the fitment foundation.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1991 Pontiac LeMans?
Yes, modifications can affect tire fitment on a 1991 Pontiac LeMans even when the original size is straightforward. The car uses 175/70R13 on a 13-inch rim, but wheel changes, altered ride height, or suspension repairs done with non-original parts can change the space available around that tire.
A LeMans that has aftermarket wheels should be checked for actual rim width and offset before a new tire is selected. Clearance at the fenders, struts, and steering range also deserves attention, especially on an older compact where replacement components may not match the original setup exactly.
What should I inspect before driving a 1991 Pontiac LeMans on new tires?
Before driving a 1991 Pontiac LeMans on new tires, inspect the wheels, valve stems, lug hardware, and overall wheel condition. It also makes sense to look over the suspension and steering for looseness or wear, since even the correct 175/70R13 tire cannot compensate for neglected front-end parts.
Once the tires are mounted, confirm pressure, check for even clearance at full steering lock, and watch for any rubbing on the first short drive. Older cars that have sat for long periods also deserve a close look for fluid leaks, brake condition, and alignment issues before regular road use resumes.
How should 175/70R13 tires on a collector 1991 Pontiac LeMans be maintained?
Collector-car maintenance for 175/70R13 tires on a 1991 Pontiac LeMans starts with regular pressure checks, visual inspections, and attention to age-related deterioration. Even low-mileage tires can develop cracking, flat spotting, air loss, or sidewall damage when a stored car is driven only occasionally.
Storage conditions matter as much as mileage on a lightly used LeMans. Keeping the car away from prolonged sunlight, excess heat, and moisture helps preserve the tires, and periodic movement can reduce long-term flat spotting. Before any longer drive, inspect tread and sidewalls carefully and confirm the wheels remain clean and structurally sound.
