The 1988 Pontiac Fiero occupies a distinctive place in Pontiac history, pairing the Fiero’s compact mid-engine layout with the final-year chassis and trim mix that enthusiasts still pay close attention to. Tire selection matters on this car because fitment is not uniform across the range. The 1988 Pontiac Fiero uses four primary radial sizes, with 15-inch staggered sizing on GT front and rear positions and 14-inch sizes on Sport and Value Leader models. Available choices also vary by sidewall style, brand, and touring-versus-performance presentation. Getting the right tire starts with confirming the exact sub-model, wheel diameter, and in the GT’s case, front versus rear placement.
Which Tire Size Is Right for The 1988 Pontiac Fiero
The 1988 Pontiac Fiero uses four primary tire sizes, and the correct one depends on both the sub-model and wheel diameter. GT models use 15-inch radial sizes with different front and rear fitments, while Sport and Value Leader models use 14-inch radial sizes. Before choosing a tire, confirm the exact sub-model and make sure the car still has the wheel setup it uses today.
A 205/60R15 is a metric radial tire with a 205-millimeter section width, a 60-series aspect ratio, and a 15-inch rim diameter. On the 1988 Pontiac Fiero, this size is part of the GT fitment and should be treated as a position-specific size rather than a universal Fiero choice. Available options include blackwall, wide whitewall, and raised white letter styling from brands such as Michelin, American Classic, Coker Classic, and BFGoodrich. This size is worth evaluating carefully if the goal is to keep the GT’s intended wheel setup while choosing between a traditional appearance and a more contemporary radial presentation.
A 215/60R15 is a metric radial tire with a 215-millimeter section width, a 60-series profile, and a 15-inch rim diameter. On the 1988 Pontiac Fiero, this size serves the GT fitment and should be matched to the correct axle position rather than assumed across the full model line. Product choices range from blackwall sport-oriented tires to wide whitewall and redline offerings, with brands including American Classic, BFGoodrich, Dunlop, Avon, and Vredestein. This size becomes the right path when the car has the proper 15-inch GT wheel arrangement and the buyer wants to compare appearance-driven and performance-style radial options.
A 185/75R14 is a metric radial tire with a 185-millimeter section width, a 75-series aspect ratio, and a 14-inch rim diameter. On the 1988 Pontiac Fiero, this size applies to Sport and Value Leader models rather than the GT’s 15-inch setup. Current choices center on narrow whitewall styling from brands such as Tornel, Maxxis, and Travelstar, giving this size a distinctly traditional presentation compared with the blackwall performance look seen elsewhere in the Fiero range. It is the size to consider when preserving a 14-inch Fiero configuration with a more classic sidewall appearance.
A 195/70R14 is a metric radial tire with a 195-millimeter section width, a 70-series profile, and a 14-inch rim diameter. This size is used on 1988 Pontiac Fiero Sport and Value Leader models, so it belongs to the 14-inch side of the Fiero fitment story rather than the GT’s staggered 15-inch arrangement. The available option in this size is a Dunlop Sport Classic blackwall, which gives it a more restrained, sport-oriented character than the narrow whitewall 185/75R14 choices. This size deserves attention when the goal is to stay with a 14-inch wheel while favoring a lower-profile metric radial look.
Sub-model fitment matters on the 1988 Pontiac Fiero because the range is split between 15-inch GT tires and 14-inch Sport and Value Leader tires. Checking the exact sub-model, and for GT cars the front or rear position, prevents ordering the right size for the wrong wheel setup.

1988 Pontiac Fiero GT Front
The 1988 Pontiac Fiero GT Front uses a 15-inch radial front fitment that is different from the GT rear. Tire choice here is less about finding any Fiero tire and more about keeping the proper front size while comparing blackwall, wide whitewall, or raised white letter options.
The 1988 Pontiac Fiero GT Rear uses its own 15-inch radial rear size, separate from the GT front. That makes rear tire selection a position-specific decision, with choices that range from traditional whitewall or redline styling to blackwall sport-oriented tires.
The 1988 Pontiac Fiero Sport uses 14-inch radial fitments rather than the GT’s 15-inch arrangement. Tire selection for this sub-model starts with confirming which 14-inch size the car uses now, then deciding between a classic narrow whitewall look and a more performance-flavored blackwall presentation.
The 1988 Pontiac Fiero Value Leader shares the 14-inch radial side of Fiero fitment instead of the GT’s staggered 15-inch setup. Choosing tires for this sub-model means confirming the exact 14-inch size on the car and matching the sidewall style to either a restoration-minded or more understated road-use appearance.
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.

Common 1988 Pontiac Fiero tire questions usually come down to sub-model fitment, 14-inch versus 15-inch wheels, GT front and rear sizing, and how to choose among blackwall, whitewall, redline, and RWL radial options.
Tire Size & Fitment
What tire size fits a 1988 Pontiac Fiero?
The 1988 Pontiac Fiero uses four primary radial tire sizes: 205/60R15, 215/60R15, 185/75R14, and 195/70R14. GT models use 15-inch sizes, with 205/60R15 at the front and 215/60R15 at the rear. Sport and Value Leader models use 14-inch sizes, either 185/75R14 or 195/70R14.
That means the right tire is tied to the exact version of the car, not just the model name. Start by confirming whether the Fiero is a GT, Sport, or Value Leader, then verify whether it still has its current wheel diameter. On GT cars, front and rear positions need to be checked separately before selecting tires.
What size rim does a 1988 Pontiac Fiero use?
A 1988 Pontiac Fiero uses either 14-inch or 15-inch rims, depending on the sub-model and tire size. The 205/60R15 and 215/60R15 sizes use 15-inch rims, while the 185/75R14 and 195/70R14 sizes use 14-inch rims. Rim diameter is part of the tire size itself, so it must match exactly.
The practical step is to confirm the wheel diameter on the car before comparing tires. Many Fieros have changed hands for decades, and aftermarket wheels or swapped factory wheels can change what the car needs today. On a GT, also confirm whether you are measuring the front or rear wheel before choosing a replacement tire.
Why does the 1988 Pontiac Fiero have more than one tire size?
The 1988 Pontiac Fiero has more than one tire size because different sub-models use different wheel and tire combinations. GT models use a staggered 15-inch setup with one size in front and another in back, while Sport and Value Leader models use 14-inch radial sizes. The tire size difference is part of the car’s specific configuration.
That makes identification more important than it would be on a single-size vehicle. A buyer should confirm the sub-model, check the wheel diameter, and look at the actual tire size already mounted before ordering replacements. On a GT, treating all four corners the same can lead to choosing the correct series but the wrong size for one axle.
Choosing the Right Tire
What should I consider when choosing a 1988 Pontiac Fiero tire?
Start with the correct size and wheel diameter for the exact 1988 Pontiac Fiero sub-model. GT fitment differs front to rear, while Sport and Value Leader models use 14-inch sizes. Once size is confirmed, the real comparison becomes sidewall style, tire series, rim-width compatibility where stated, and whether the car is being kept visually traditional or used more as a road car.
It helps to think about the car’s current setup before focusing on appearance alone. A narrow whitewall 14-inch tire creates a very different presentation than a blackwall or RWL 15-inch tire, and not every style exists in every size. Matching the tire to the car’s wheels, stance, and intended use usually leads to a better choice than chasing one styling cue by itself.
What sidewall styles are available for 1988 Pontiac Fiero tires?
Sidewall choices for the 1988 Pontiac Fiero include blackwall, narrow whitewall, wide whitewall, redline, and RWL depending on size. The 14-inch 185/75R14 options lean toward narrow whitewall styling, the 195/70R14 option is blackwall, and the 15-inch GT-related sizes include blackwall, wide whitewall, redline, and raised white letter treatments.
The sidewall style should be chosen after the correct tire size is confirmed, because the appearance options change from one fitment to another. A GT owner looking for a more performance-oriented look may focus on blackwall or RWL choices, while a more traditional presentation may point toward whitewall or redline options where available in the proper size.
What brands offer tires for the 1988 Pontiac Fiero?
Brands available across 1988 Pontiac Fiero tire sizes include Michelin, American Classic, Coker Classic, BFGoodrich, Dunlop, Avon, Vredestein, Tornel, Maxxis, and Travelstar. The exact brand selection depends on the tire size, so a 15-inch GT fitment does not draw from the same product pool as a 14-inch Sport or Value Leader fitment.
Brand comparison is most useful after the size question is settled. Some sizes offer a wider mix of touring-style, classic-look, and sport-oriented options, while others are much narrower in scope. Buyers should compare sidewall treatment, tire series, rim-width specification where available, and overall visual character rather than assuming every brand offers the same type of tire in each Fiero size.
Restoration & Appearance
Which tire should I choose for a period-style 1988 Pontiac Fiero?
A period-style 1988 Pontiac Fiero tire starts with the correct size for the exact sub-model and wheel diameter. From there, the visual direction depends on the car. GT-related 15-inch sizes offer blackwall, wide whitewall, redline, and RWL choices, while 14-inch fitments for Sport and Value Leader models include narrow whitewall and blackwall options.
The right appearance depends on whether the goal is a restoration-minded presentation or a more personalized 1980s street look. Sidewall style should complement the wheels and trim already on the car rather than being chosen in isolation. If exact originality matters, compare the tire choice against period photos, marque references, and vehicle-specific documentation before making a final decision.
How does tire construction affect the appearance of a restored 1988 Pontiac Fiero?
Tire construction is simpler on the 1988 Pontiac Fiero because the primary fitments are radial across the range. The appearance difference comes less from bias-ply versus radial choices and more from the size itself, the sidewall treatment, and the tire series selected. A blackwall performance-style radial gives a different visual result than a narrow or wide whitewall radial.
That means restoration appearance is shaped mostly by proportion and sidewall design. A GT with staggered 15-inch sizing can look noticeably different from a 14-inch Sport or Value Leader even before brand choice enters the picture. Keeping the correct wheel diameter and proper front or rear size relationship is usually more important visually than chasing a specific tread or branding detail.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1988 Pontiac Fiero?
Yes, modifications can affect tire fitment on a 1988 Pontiac Fiero. Aftermarket wheels, changes in wheel width, suspension alterations, lowering, or body modifications can all change the space available for the tire. On GT models, fitment can become even more sensitive because the car uses different front and rear sizes rather than one uniform setup.
A modified Fiero should be checked at the wheel, not just by model year. Verify actual wheel diameter and width, then inspect steering clearance, spring and strut clearance, and fender space at both ride height and full lock where relevant. Even when the tire size matches a standard Fiero fitment, changes elsewhere on the car can alter what works cleanly.
What should I inspect before driving a 1988 Pontiac Fiero on new tires?
Before driving a 1988 Pontiac Fiero on new tires, inspect the wheels for the correct diameter and condition, make sure the tires are mounted in the proper sizes for the car’s sub-model, and confirm that inflation is set appropriately for the tire and vehicle setup. It is also worth checking for uneven suspension wear, loose steering components, and obvious alignment issues.
A short visual and road-use check can prevent a lot of trouble. Look for adequate clearance around the tire, especially on a GT with staggered 15-inch sizing, and recheck for rubbing after the first miles of driving. It also helps to inspect valve stems, verify lug torque, and make sure the spare and roadside plan still make sense for the wheel arrangement on the car.
How should tires on a collector 1988 Pontiac Fiero be maintained?
Tires on a collector 1988 Pontiac Fiero should be maintained with regular pressure checks, periodic visual inspection, and careful storage habits. Even a low-mileage car can develop issues from age, underinflation, prolonged sitting, or environmental exposure. Watch for sidewall cracking, cuts, bulges, irregular tread wear, and slow air loss, especially on a car that is driven infrequently.
Long-term care matters as much as mileage on an enthusiast car. Keeping the Fiero away from prolonged sunlight, excess heat, moisture, and ozone sources can help preserve the tires between drives. It is also smart to inspect the tires before every outing and after long storage, since a car that looks fine in the garage may still have age-related tire concerns.
