The 1989 Pontiac LeMans came at the end of an era when compact front-wheel-drive cars balanced everyday practicality with trim-level differences that could noticeably affect wheel and tire fitment. For owners today, that matters because this exact model year uses three different radial tire sizes depending on sub-model: 185/60R14, 175/70R13, or 175/70R14. That means the first step is confirming whether the car is a GSE, LE, SE, or Value Leader before choosing a tire. From there, the decision shifts to metric size interpretation, rim diameter, and whether a blackwall or narrow whitewall presentation better suits the car’s intended look and road use.
Which Tire Size Is Right for The 1989 Pontiac LeMans
The 1989 Pontiac LeMans uses three primary tire sizes, and the correct one depends on the exact sub-model and wheel diameter. Two sizes fit 14-inch rims, while one fits a 13-inch rim, so identifying both the sub-model and the actual wheel on the car comes first. Once that is confirmed, the choice becomes selecting the right radial tire within that size and appearance style.
185/60R14 is a metric radial size where 185 is the nominal section width in millimeters, 60 is the aspect ratio, R identifies radial construction, and 14 is the rim diameter in inches. On the 1989 Pontiac LeMans, this size is used on 14-inch-wheel sub-models and keeps the selection in a modern radial format familiar to late-model buyers. Available choices in this size include a Michelin blackwall tire from the Michelin Pilot Exalto PE2 series. It is the size to evaluate when the car is equipped with the correct 14-inch wheel and a lower-profile metric fitment.
175/70R13 is a metric radial size with a 175-millimeter nominal section width, a 70-series aspect ratio, radial construction, and a 13-inch rim diameter. For the 1989 Pontiac LeMans, this size belongs to a specific 13-inch-wheel sub-model, so wheel diameter must be confirmed before ordering. In available replacement choices, this size appears as an Avon blackwall tire in the CR6ZZ series, giving it a distinct product character compared with the 14-inch options. It is the right direction when maintaining the proper 13-inch fitment rather than moving to a different wheel setup.
175/70R14 uses the same 175-millimeter nominal section width and 70-series profile as the 13-inch version, but it is built for a 14-inch rim. On the 1989 Pontiac LeMans, that makes it important not to confuse this size with 175/70R13 simply because the width and profile look similar. Available product choice in this size includes a Travelstar radial with a narrow whitewall in the UN106 series, which gives it a more traditional visual presentation than a plain blackwall. This size is worth considering when the car uses the correct 14-inch wheel and appearance is part of the decision.
Sub-model fitment on the 1989 Pontiac LeMans is not uniform, and the tire decision starts with identifying the exact trim. Wheel diameter also changes between some versions, so confirming both the sub-model and the wheels currently on the car helps prevent choosing the wrong size.

1989 Pontiac LeMans GSE
The 1989 Pontiac LeMans GSE uses a 185/60R14 radial tire on a 14-inch rim. That makes the selection process more about choosing the right product within that metric size and confirming that the car still wears the proper wheel diameter.
The 1989 Pontiac LeMans LE uses a 175/70R13 radial tire on a 13-inch rim. Tire selection for this sub-model depends on keeping the correct 13-inch fitment in mind and avoiding confusion with the two 14-inch LeMans sizes.
The 1989 Pontiac LeMans SE uses the same 185/60R14 radial tire size as the GSE. That keeps fitment straightforward as long as the car still has its proper 14-inch wheels, leaving product character and road-use priorities as the main points of comparison.
The 1989 Pontiac LeMans Value Leader uses a 175/70R14 radial tire on a 14-inch rim. Since another LeMans sub-model uses a 175-series tire on a 13-inch wheel, verifying rim diameter is especially important before selecting a replacement.
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 1989 Pontiac LeMans Tires for Sale
Available 1989 Pontiac LeMans tire choices vary by sub-model size and include Michelin, Avon, and Travelstar radials. Buyers can compare blackwall and narrow whitewall presentations, along with differences in tire series and rim-width compatibility where those specifications apply.
Common 1989 Pontiac LeMans tire questions usually come down to sub-model fitment, 13-inch versus 14-inch rims, metric radial sizing, sidewall appearance, and what to inspect before putting a lightly used older car back on the road.
Tire Size & Fitment
What tire size fits a 1989 Pontiac LeMans?
A 1989 Pontiac LeMans can use 185/60R14, 175/70R13, or 175/70R14, depending on the sub-model. The GSE and SE use 185/60R14, the LE uses 175/70R13, and the Value Leader uses 175/70R14. All three are radial tire sizes, but they are not interchangeable just because they belong to the same model year.
The practical step is to confirm the exact sub-model and then check the actual wheel diameter on the car. Older compact cars are sometimes modified or fitted with replacement wheels, so the badge alone is not always enough. Matching the tire size to both the sub-model and the wheel helps keep the fitment, proportions, and clearance relationship in line with the intended setup.
What size rim does a 1989 Pontiac LeMans use?
A 1989 Pontiac LeMans uses either a 13-inch or 14-inch rim, depending on sub-model. The LE uses a 13-inch rim with 175/70R13 tires, while the GSE, SE, and Value Leader use 14-inch rims with either 185/60R14 or 175/70R14 tires. Rim diameter is one of the key fitment differences across this model year.
That distinction matters because a 13-inch tire cannot be mounted on a 14-inch wheel, and the reverse is also true. Before choosing a replacement, inspect the wheels actually installed on the car and make sure the tire size matches them. On an older vehicle, prior owner changes can blur the original trim-based fitment, so a quick wheel check prevents an expensive mismatch.
Why does the 1989 Pontiac LeMans have more than one tire size?
The 1989 Pontiac LeMans has more than one tire size because tire fitment changes by sub-model. Some versions use 13-inch wheels, while others use 14-inch wheels, and even among the 14-inch applications there are two different metric radial sizes. That makes trim level part of the tire decision instead of treating all 1989 LeMans models the same.
For an owner, that means the correct choice starts with identifying whether the car is an LE, GSE, SE, or Value Leader. After that, compare the size on the car, the wheel diameter, and the intended replacement tire. This is especially important if the car has had wheel changes over the years, since trim-based fitment and current wheel setup may no longer match.
Choosing the Right Tire
What should I consider when choosing a 1989 Pontiac LeMans tire?
Start with the exact size required for the specific 1989 Pontiac LeMans sub-model, since this car uses three different radial sizes. After size, focus on wheel diameter, radial construction, and the character of the available product in that fitment. Depending on size, choices may differ by brand, tire series, sidewall style, and published rim-width range.
The best comparison approach is to match the tire to how the car will actually be used. A daily-driven survivor, an occasional weekend car, and a restoration-minded example may lead to different preferences in sidewall appearance or product type. It also helps to verify the car has the proper wheels, since choosing the right tire becomes much easier once diameter and fitment are confirmed.
What sidewall styles are available for 1989 Pontiac LeMans tires?
Available sidewall styles for 1989 Pontiac LeMans tires include blackwall and narrow whitewall, depending on the tire size. The 185/60R14 and 175/70R13 options are offered as blackwalls, while the 175/70R14 option is available with a narrow whitewall. That means sidewall appearance is tied to the correct fitment rather than being universal across all LeMans sub-models.
For selection purposes, think about whether the car calls for a plain, understated look or a more traditional presentation. A narrow whitewall can change the visual tone of the vehicle noticeably, especially on a compact late-1980s car. Appearance should still come after correct size and wheel confirmation, since the right sidewall style only helps if it is attached to the proper tire fitment.
What brands offer tires for the 1989 Pontiac LeMans?
Tires for the 1989 Pontiac LeMans are available from Michelin, Avon, and Travelstar across the three sub-model fitments. Michelin covers the 185/60R14 application, Avon covers 175/70R13, and Travelstar covers 175/70R14. Since those brands correspond to different sizes, brand choice is partly determined by the sub-model and wheel setup rather than simple personal preference.
That makes it useful to approach the purchase by size first and brand second. Once the correct fitment is confirmed, compare the available tire series, sidewall style, and any published rim-width details that apply to that size. On a vehicle with multiple trim-based fitments like the LeMans, narrowing the right size early prevents chasing a brand option that belongs to a different wheel diameter.
Restoration & Appearance
Which tire should I choose for a period-style 1989 Pontiac LeMans?
A period-style 1989 Pontiac LeMans tire choice starts with using the correct sub-model size: 185/60R14, 175/70R13, or 175/70R14. Since all primary fitments for this model year are radial, the visual decision is less about bias-ply versus radial and more about the tire’s sidewall treatment and overall presentation. Blackwall and narrow whitewall options create different looks depending on size.
For a restoration-oriented car, keeping the proper size and wheel diameter matters more than forcing a favorite sidewall style onto the wrong fitment. A narrow whitewall can give the car a softer, more traditional appearance, while a blackwall keeps things cleaner and more understated. When exact originality matters, it is smart to compare against period photos, brochures, or marque-specific references for the specific trim.
Does correct tire fitment matter for a 1989 Pontiac LeMans restoration?
Correct tire fitment matters on a 1989 Pontiac LeMans restoration because the car uses different sizes across its sub-models, including both 13-inch and 14-inch wheel applications. Using the proper size helps preserve the intended stance, wheel-to-tire proportion, and overall look of the finished car. It also avoids blending trim-level details that did not belong together originally.
From a practical standpoint, restoration fitment is about more than appearance alone. A tire that matches the right wheel diameter and sub-model setup is also easier to evaluate for clearance and overall compatibility. Before mounting new tires, confirm the wheels on the car, inspect for prior modifications, and make sure the chosen size supports the visual direction and road use planned for the finished LeMans.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1989 Pontiac LeMans?
Yes, modifications can affect tire fitment on a 1989 Pontiac LeMans, especially because this model already spans both 13-inch and 14-inch wheel applications. Aftermarket wheels, different offsets, suspension changes, or body alterations can change the space available around the tire. That matters even when the tire size itself is correct for a stock sub-model.
A sensible approach is to verify more than just the sidewall size before purchasing. Check the wheel diameter and width, look at steering and fender clearance, and compare the car’s current setup to its intended trim-based fitment. On a compact car, small changes in wheel and suspension hardware can have a noticeable effect, so the final fit should be judged on the actual vehicle.
What should I inspect before driving a 1989 Pontiac LeMans on new tires?
Before driving a 1989 Pontiac LeMans on new tires, inspect the wheels for damage, confirm the tire size matches the sub-model and rim diameter, and make sure each tire is properly seated and inflated. It is also worth checking the valve stems, looking for suspension wear, and confirming that the tires clear the fenders and steering components through the full range of motion.
An older car that has spent time parked deserves extra attention before regular road use. Look for uneven wear patterns that might point to alignment or suspension issues, and recheck inflation after the first few drives. A short local test drive helps reveal rubbing, pull, vibration, or air loss before the LeMans is trusted on a longer trip.
How should tires on a collector 1989 Pontiac LeMans be maintained?
Tires on a collector 1989 Pontiac LeMans should be kept clean, properly inflated, and inspected regularly for cracking, bulges, cuts, and uneven wear. Because many older cars are driven infrequently, age and storage conditions can matter as much as mileage. Any of the LeMans radial sizes should also be watched for slow air loss, especially after seasonal storage.
Storage habits make a real difference on a low-use car. Keeping the vehicle away from prolonged sunlight, heat, moisture, and ozone sources helps protect the sidewalls over time. It also helps to move the car occasionally or avoid letting it sit on underinflated tires for long periods. Regular visual checks are simple, but they can catch condition issues well before road use becomes risky.
