The 1986 Pontiac Fiero sits in an interesting spot in 1980s Pontiac history, combining compact dimensions with mid-engine layout and distinct sub-model personalities. For tire selection, that matters more than it might on a conventional front-engine car, because this Fiero uses multiple radial sizes across 14-inch and 15-inch wheel fitments, and the GT carries a staggered front-and-rear setup. Available choices range from blackwall sport-oriented radials to wide whitewall, narrow whitewall, redline, and raised white letter styles depending on size. The right pick starts with confirming the exact sub-model and wheel diameter, then matching the tire’s appearance and road-use character to the way the car is being kept or driven.
Which Tire Size Is Right for The 1986 Pontiac Fiero
The 1986 Pontiac Fiero uses four primary tire sizes, and the correct one depends on the exact sub-model and wheel diameter. Fitment varies between 14-inch and 15-inch applications, and the GT adds another layer by using different front and rear sizes. Before choosing a tire, confirm whether the car is a GT Front, GT Rear, SE Coupe, Sport, or Value Leader setup and verify the wheels currently on the car.
205/60R15 is a metric radial size in which 205 identifies the nominal section width in millimeters, 60 is the aspect ratio, and 15 is the rim diameter in inches. On the 1986 Pontiac Fiero, this size is part of the GT fitment and belongs on a 15-inch wheel. Available choices include blackwall, wide whitewall, and raised white letter styles from brands such as Michelin, American Classic, Coker Classic, and BFGoodrich. This size suits buyers who need the correct GT front fitment and want to balance appearance, brand preference, and intended driving use.
215/60R15 is a metric radial size with a 215-millimeter nominal section width, a 60-series profile, and a 15-inch rim diameter. This size serves the 1986 Pontiac Fiero GT rear position, making it distinct from the GT front tire and important to verify before ordering. Product choices include blackwall, wide whitewall, redline, and raised white letter designs across American Classic, BFGoodrich, Dunlop, Avon, and Vredestein lines. It is the key size for owners preserving the GT’s staggered setup or comparing a more traditional sidewall look with a sportier presentation.
195/70R14 is a metric radial size where 195 gives the nominal section width in millimeters, 70 is the aspect ratio, and 14 indicates rim diameter. On the 1986 Pontiac Fiero, this size appears on 14-inch applications rather than the GT’s 15-inch setup. The available product selection in this size centers on a blackwall Dunlop Sport Classic, which keeps the choice straightforward for buyers focused on correct size and road-use compatibility. It is a useful fitment to confirm carefully on SE Coupe, Sport, and Value Leader cars, especially if the wheels may have been changed over time.
185/75R14 is a metric radial size that uses a 185-millimeter nominal section width, a 75-series profile, and a 14-inch rim. This is one of the 14-inch fitments used on certain 1986 Pontiac Fiero Sport and Value Leader applications, so it should not be assumed to apply across the whole model line. Available options lean toward traditional narrow whitewall styling from Tornel, Maxxis, and Travelstar rather than a sport blackwall look. Buyers considering this size usually need to confirm both sub-model and wheel setup, then decide whether a classic whitewall appearance matches the character of the car.
Sub-model fitment on the 1986 Pontiac Fiero is not one-size-fits-all. Tire choice depends on identifying the exact configuration, since wheel diameter changes across the range and the GT uses different sizes at the front and rear.

1986 Pontiac Fiero GT Front
The 1986 Pontiac Fiero GT Front uses a 15-inch radial fitment distinct from the GT rear. Tire selection here should preserve the intended front sizing while letting the owner choose among blackwall, wide whitewall, or raised white letter presentations.
The 1986 Pontiac Fiero GT Rear uses its own 15-inch radial size, separate from the front position. That makes rear tire selection especially important on GT cars, whether the goal is a sport-oriented blackwall look or a more traditional redline, whitewall, or RWL appearance.
The 1986 Pontiac Fiero SE Coupe uses a 14-inch radial tire size that differs from the GT setup. Choosing for this sub-model is more straightforward, with the main priorities being correct wheel diameter, proper overall fitment, and the kind of road-use character desired.
The 1986 Pontiac Fiero Sport can use one of two 14-inch radial sizes, so confirming the wheels currently on the car matters before ordering. Once the exact setup is verified, the decision shifts toward appearance and product style, especially if a narrow whitewall presentation is part of the plan.
The 1986 Pontiac Fiero Value Leader also uses 14-inch radial fitments, but more than one size may apply depending on the wheel setup. A careful check of the current wheels and tire markings helps narrow the choice before comparing blackwall versus classic whitewall-style 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.

Tire Size & Fitment
What tire size fits a 1986 Pontiac Fiero?
A 1986 Pontiac Fiero can use 205/60R15, 215/60R15, 195/70R14, or 185/75R14, depending on the exact sub-model and wheel position. The GT uses a staggered 15-inch setup with 205/60R15 in front and 215/60R15 in the rear, while other Fiero sub-models use 14-inch radial sizes.
The first step is confirming both the sub-model and the wheels actually on the car today. Many Fieros have changed hands over the years, and wheel swaps can blur the original fitment pattern, so checking the current rim diameter and existing tire markings helps prevent choosing a size meant for a different version.
What size rim does a 1986 Pontiac Fiero use?
The 1986 Pontiac Fiero uses either a 14-inch or 15-inch rim, depending on sub-model. GT front and rear fitments are built around 15-inch wheels, while SE Coupe, Sport, and Value Leader applications use 14-inch tire sizes in the fitments covered here.
Wheel diameter should be confirmed before focusing on brand or sidewall style, because a 14-inch tire and a 15-inch tire are not interchangeable. It also helps to check wheel width and overall wheel type if the car has aftermarket rims, since that can affect which products within the correct size are the better match.
Why does the 1986 Pontiac Fiero have more than one tire size?
The 1986 Pontiac Fiero has more than one tire size because fitment varies by sub-model, wheel diameter, and in the case of the GT, by axle position. The GT uses one size in front and a different size in the rear, while other versions use 14-inch radial sizes instead of the GT’s 15-inch setup.
That means tire selection is not just a matter of matching the year and model name. A buyer should verify whether the car is a GT, SE Coupe, Sport, or Value Leader configuration and then confirm the wheel diameter currently installed, especially if the Fiero has been modified or restored with different wheels.
Choosing the Right Tire
What should I consider when choosing a 1986 Pontiac Fiero tire?
Start with the correct size for the exact sub-model and wheel position, since a 1986 Pontiac Fiero can use multiple radial sizes across 14-inch and 15-inch applications. After size is confirmed, the important comparisons are construction details within the radial category, wheel compatibility, sidewall style, tire series, and the kind of road use the car will actually see.
A GT owner may be deciding between a sportier blackwall or RWL presentation, while a 14-inch car may lean toward a more traditional whitewall look. Rim-width specifications, load figures, and overall tire character are also worth comparing so the final choice matches both the car’s setup and the owner’s visual goals.
What sidewall styles are available for 1986 Pontiac Fiero tires?
Sidewall styles for the 1986 Pontiac Fiero include blackwall, wide whitewall, narrow whitewall, redline, and RWL, depending on the tire size. The 15-inch GT-related sizes offer the broadest visual range, while the 185/75R14 options center on narrow whitewall styling and the 195/70R14 offering is a blackwall radial.
That variety lets the tire influence the car’s overall personality without changing the basic fitment. A buyer should still choose sidewall treatment only after confirming the correct size and wheel diameter, since the appearance options differ noticeably from one Fiero fitment to another and not every style is available in every size.
What brands offer tires for the 1986 Pontiac Fiero?
Brands available for 1986 Pontiac Fiero tire sizes include Michelin, American Classic, Coker Classic, BFGoodrich, Dunlop, Avon, Vredestein, Tornel, Maxxis, and Travelstar. Brand choice depends heavily on the exact size, with the 15-inch fitments offering the widest range and the 14-inch sizes having a narrower but still useful selection.
The practical way to compare brands is within the correct tire size rather than across the whole model line. Once the fitment is narrowed down, look at the brand alongside sidewall style, series name, rim-width compatibility, and load specification so the tire suits both the wheel setup and the type of Fiero being maintained.
Restoration & Appearance
Which tire should I choose for a period-style 1986 Pontiac Fiero?
A period-style 1986 Pontiac Fiero tire starts with the correct size for the exact sub-model and wheel position, then moves to the visual character you want the car to project. Blackwall tires suit a more performance-oriented 1980s look, while whitewall, redline, or RWL options can shift the presentation toward a more stylized or restoration-oriented direction.
The best approach is to match the tire’s sidewall treatment and series character to the way the car is being restored rather than assuming one look suits every Fiero. Owners seeking exact originality should compare the car against period photos, sales literature, or marque-specific references before settling on a particular sidewall treatment.
How does tire construction affect the appearance of a restored 1986 Pontiac Fiero?
On the 1986 Pontiac Fiero, construction is less of a visual dividing line than sidewall treatment because the primary fitments covered here are radial sizes. The bigger appearance change comes from whether the tire is a blackwall, wide whitewall, narrow whitewall, redline, or raised white letter design, especially on the 15-inch GT fitments.
That said, tire proportions still matter to the finished look of the car. Staying with the correct primary size helps preserve the stance and wheel-to-tire relationship intended for the sub-model, while changing size or wheel diameter can alter the visual balance even before the car turns a wheel.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1986 Pontiac Fiero?
Yes, modifications can affect tire fitment on a 1986 Pontiac Fiero, especially because this model already uses more than one wheel diameter and, in GT form, different front and rear sizes. Aftermarket wheels, suspension changes, lowering, or body alterations can change the clearance picture even when the tire size itself seems close to stock.
A modified Fiero should be checked for actual wheel diameter, width, and the space available at steering lock and through suspension travel before a tire is chosen. That is particularly important when replacing only one axle pair, since the wrong combination can upset the intended stance or create clearance problems.
What should I inspect before driving a 1986 Pontiac Fiero on new tires?
Before driving a 1986 Pontiac Fiero on new tires, inspect the wheels for correct diameter and condition, confirm lug hardware is appropriate, and make sure the tires are mounted in the proper sizes for the car’s sub-model and position. Tire pressure should be set correctly, and the suspension, steering, and alignment condition deserve attention as well.
A short initial road test helps reveal rubbing, vibration, pull, or clearance concerns before the car is used more seriously. It is also smart to recheck pressure and lug torque after the first drive, especially on a collector car that may have sat for long periods or recently returned to the road.
How should tires on a collector 1986 Pontiac Fiero be maintained?
Tires on a collector 1986 Pontiac Fiero should be inspected regularly for cracking, cuts, bulges, uneven wear, and gradual air loss, even if the car is driven infrequently. Collector cars often age their tires through time and storage conditions rather than mileage, so appearance alone is not enough to judge road readiness.
Proper inflation, clean storage conditions, and protection from prolonged sunlight, heat, and ozone sources help preserve the tires between drives. It also pays to move the car occasionally or store it in a way that avoids long-term flat spotting, then give the tires another visual check before heading out for a longer trip.
