The 1988 Pontiac Grand Am sits squarely in the late-1980s front-wheel-drive sport-coupe and sedan market, a period when Pontiac leaned on sharp styling and trim-level distinction to give everyday cars a more athletic identity. That matters at the tire level, because this exact model year uses three different radial sizes depending on configuration: 185/80R13, 195/70R14, and 215/60R14. The available choices range from traditional whitewall radials for a more conservative presentation to blackwall and raised white letter options that better suit a sportier look. The right decision starts with confirming the exact sub-model and wheel diameter, then choosing the appearance and tire character that match the car's current setup.
Which Tire Size Is Right for The 1988 Pontiac Grand Am
The 1988 Pontiac Grand Am uses three primary tire sizes, and the correct one depends on sub-model and wheel diameter. Base and LE models use either 185/80R13 or 195/70R14 radial tires, while the SE uses 215/60R14. Before choosing a tire, confirm both the exact trim and whether the car is riding on 13-inch or 14-inch wheels, since that determines the starting point for every other fitment decision.
185/80R13 is a metric radial size: 185 is the nominal section width in millimeters, 80 is the aspect ratio, R identifies radial construction, and 13 is the wheel diameter in inches. On a 1988 Pontiac Grand Am, this size supports a taller-profile radial look and fits 13-inch wheels. Available options include Maxxis, BFGoodrich, and Coker Classic, with narrow whitewall and wide whitewall sidewall treatments across series such as Maxxis Radial, Silvertown Radial, and Star Series. This size is worth considering when the car retains its 13-inch wheel setup and the goal is a more traditional late-1980s passenger-car appearance.
195/70R14 is a metric radial size in which 195 denotes nominal section width in millimeters, 70 is the aspect ratio, R marks radial construction, and 14 indicates the rim diameter in inches. For the 1988 Pontiac Grand Am, it is one of the 14-inch wheel fitments used on Base and LE models. The available product in this size is a Dunlop Sport Classic blackwall, giving this fitment a distinctly road-oriented and understated appearance. This size makes sense when the car is already equipped with 14-inch wheels and the buyer wants to stay with the proper wheel diameter and a modern-looking blackwall presentation.
215/60R14 is a metric radial size where 215 represents nominal section width in millimeters, 60 is the aspect ratio, R stands for radial construction, and 14 is the wheel diameter in inches. On the 1988 Pontiac Grand Am, this size is tied to the SE and reflects a wider, lower-profile 14-inch radial fitment than the other Grand Am sizes. The available choice in this size is the BFGoodrich Radial T/A with raised white letter sidewalls, a styling cue that suits a sportier period presentation. This is the size to evaluate when the car is an SE and still carries the wheel and clearance setup intended for this broader tire.
Sub-model fitment matters on the 1988 Pontiac Grand Am because tire size is not the same across the full range. Base and LE models share the same two radial fitment paths, while the SE moves to a different 14-inch size, so trim identification should come before tire selection.

1988 Pontiac Grand Am Base
The 1988 Pontiac Grand Am Base uses either a 185/80R13 radial or a 195/70R14 radial, depending on the wheel package on the car. That makes wheel-diameter confirmation especially important before comparing whitewall or blackwall options in the available product range.
The 1988 Pontiac Grand Am LE follows the same tire-fitment pattern as the Base, using either 185/80R13 or 195/70R14 radial tires. Tire choice starts with checking whether the car has 13-inch or 14-inch wheels, then narrowing the selection by sidewall style and overall appearance.
The 1988 Pontiac Grand Am SE uses a 215/60R14 radial tire, setting it apart from the Base and LE fitments. That points the selection process toward the proper 14-inch sport-oriented size and makes it important to confirm that the car still retains the wheel and suspension setup intended for that tire.
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 1988 Pontiac Grand Am?
A 1988 Pontiac Grand Am can use 185/80R13, 195/70R14, or 215/60R14 radial tires, depending on the sub-model and wheel package. Base and LE models use either 185/80R13 or 195/70R14, while the SE uses 215/60R14.
The practical step is to verify both the trim level and the actual wheel diameter on the car before choosing a replacement tire. Many older cars have had wheels changed over time, and a Grand Am wearing 14-inch wheels needs a different tire starting point than one still running 13-inch wheels.
What size rim does a 1988 Pontiac Grand Am use?
The 1988 Pontiac Grand Am uses either a 13-inch or 14-inch rim, depending on the tire size and configuration. The 185/80R13 fitment uses a 13-inch rim, while both 195/70R14 and 215/60R14 use 14-inch rims.
Wheel diameter should be confirmed from the tire sidewall or by measuring the wheel before ordering tires. It also helps to check wheel width, especially if the car has aftermarket wheels, because correct diameter alone does not guarantee the same tire will suit the wheel or preserve proper clearance.
Do all 1988 Pontiac Grand Am sub-models use the same tire size?
No, all 1988 Pontiac Grand Am sub-models do not use the same tire size. Base and LE models share 185/80R13 and 195/70R14 fitments, while the SE uses 215/60R14.
That difference affects more than the numbers on the sidewall. It changes wheel diameter, tire profile, and the range of available sidewall styles, so the right replacement starts with identifying the exact sub-model and checking whether the car still carries its intended wheel setup rather than assuming all Grand Ams use the same tire.
Choosing the Right Tire
What should I consider when choosing a tire for a 1988 Pontiac Grand Am?
Start with the correct size for the car's trim and wheel diameter: 185/80R13, 195/70R14, or 215/60R14. From there, compare the available radial options by sidewall style, tire series, brand, rim-width compatibility where stated, and whether the car's look is more traditional or more sport-oriented.
A whitewall tire creates a very different impression than a blackwall or raised white letter tire, even when the fitment is otherwise correct. It also helps to think about how the Grand Am is used, because a lightly driven collector car may prioritize appearance differently than a car that sees regular weekend road miles.
What sidewall styles are available for 1988 Pontiac Grand Am tires?
The available sidewall styles for 1988 Pontiac Grand Am tires include narrow whitewall, wide whitewall, blackwall, and raised white letter. Which styles are available depends on the tire size, with 185/80R13 offering whitewall choices, 195/70R14 appearing in blackwall form, and 215/60R14 offered with raised white letters.
That makes appearance a meaningful part of the buying decision once the correct size is confirmed. A whitewall suits a more conservative late-1980s passenger-car presentation, while blackwall and raised white letter styles lean more toward an athletic or performance-inspired look without changing the basic size requirement.
What brands offer tires for the 1988 Pontiac Grand Am?
Tires for the 1988 Pontiac Grand Am are available from Maxxis, BFGoodrich, Coker Classic, and Dunlop across the applicable sizes. Brand choice varies by fitment, so not every brand appears in every tire size used on this model.
The useful comparison is not brand name alone, but how each offering matches the car's required size and desired appearance. One Grand Am owner may need a 13-inch whitewall radial, while another may be choosing between a 14-inch blackwall or raised white letter tire, so the right brand depends on that context.
Restoration & Appearance
Which tire should I choose for a period-style 1988 Pontiac Grand Am?
A period-style 1988 Pontiac Grand Am tire choice starts with the car's correct size and wheel diameter, then moves to the visual character of the tire. Whitewall 185/80R13 radials suit a more conservative presentation, while a blackwall 195/70R14 or raised white letter 215/60R14 gives the car a sportier late-1980s look.
The best approach is to match the tire to the trim level, wheel package, and the way the car is being represented. For restoration work where exact originality matters, compare the sidewall treatment and overall stance against period photos, window-sticker references, or marque-specific documentation before making the final decision.
How does tire construction affect the appearance of a restored 1988 Pontiac Grand Am?
On a 1988 Pontiac Grand Am, construction is straightforward because the primary fitments are all radial. That means the visible appearance difference comes less from bias-ply versus radial construction and more from size, sidewall profile, and whether the tire is finished as a whitewall, blackwall, or raised white letter design.
Even within radial fitments, the car's overall presentation can change noticeably with a different profile or sidewall style. A taller 185/80R13 reads differently than a lower-profile 215/60R14, so a restoration-oriented choice should consider stance, trim level, and the period image the finished Grand Am is meant to convey.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1988 Pontiac Grand Am?
Yes, modifications can affect tire fitment on a 1988 Pontiac Grand Am. Wheel swaps, suspension changes, lowering, altered springs, or body and brake changes can all influence whether the original size range still makes sense for the car's current setup.
A Grand Am that has been changed from its original wheel package may need careful measurement before replacing tires. Check wheel diameter and width first, then inspect steering clearance, fender clearance, and the position of the tire through suspension travel so the chosen size works with the car as it sits today.
What should I inspect before driving a 1988 Pontiac Grand Am on new tires?
Before driving a 1988 Pontiac Grand Am on new tires, inspect the wheels for damage, confirm the wheel diameter and width, and make sure the tires are mounted in the correct size for the car's trim and current wheel package. It also helps to verify air pressure and look for any obvious clearance issues at full steering lock.
Older cars benefit from a broader check before returning to regular road use. Look over suspension and steering components, watch for uneven ride height, and recheck for rubbing after a short drive, especially if the car has not been on the road recently or has had wheel or suspension changes in the past.
How should tires on a collector 1988 Pontiac Grand Am be maintained?
Tires on a collector 1988 Pontiac Grand Am should be inspected regularly for air loss, cracking, bulges, cuts, and uneven wear, even if the car is driven only occasionally. Maintaining proper pressure and keeping the car on clean, dry surfaces helps protect both the tires and the way the car rides.
Storage conditions matter as much as mileage on a lightly used car. Keeping the Grand Am away from prolonged sunlight, excess heat, moisture, and ozone sources can slow age-related deterioration, and a careful visual inspection before each driving season is a smart habit for any low-use collector vehicle.
