The 1985 Pontiac Fiero sits in a distinctive place in 1980s American car history, combining compact dimensions, mid-engine layout, and sharp wedge-era styling in a way few domestic cars attempted. Buyers looking at this exact year and model usually find that tire choice is closely tied to trim level rather than a single universal setup. The 1985 Pontiac Fiero uses radial tires in three different metric sizes: 185/80R13, 195/70R14, and 215/60R14. That creates meaningful differences in rim diameter, profile, and overall appearance, with available choices ranging from whitewall styles to blackwall and raised white letter designs. Getting the right tire starts with identifying the exact sub-model and confirming which wheels are on the car today.
Which Tire Size Is Right for The 1985 Pontiac Fiero
Three different tire sizes apply to the 1985 Pontiac Fiero, and the correct one depends on the exact sub-model and wheel diameter. Two sizes use 14-inch rims, while one uses a 13-inch rim, so wheel diameter should be confirmed before anything else. Once that is settled, the decision shifts to the right metric radial size and the available brand, sidewall, and tire-series choices within that fitment.
185/80R13 is a metric radial size in which 185 refers to nominal section width in millimeters, 80 is the aspect ratio, R denotes radial construction, and 13 identifies the rim diameter in inches. On the 1985 Pontiac Fiero, this size supports the car's smaller-wheel setup and remains a true radial fitment rather than a vintage bias-ply designation. Available choices include Maxxis, BFGoodrich Silvertown Radial, and Coker Classic Star Series options, with narrow whitewall and wide whitewall presentations. This size is the right place to focus if your Fiero has the 13-inch wheel package and you want the tire appearance to match your restoration or driving goals.
215/60R14 is a metric radial size with a 215-millimeter nominal section width, a 60-series profile, and a 14-inch rim diameter. Its lower profile and wider section give it a distinctly different stance from the taller 13-inch Fiero fitment, so it should only be chosen for the configurations that use this 14-inch setup. In this size, the available product uses BFGoodrich's Radial T/A series with raised white letters, a look closely associated with period performance tires. It is the size to evaluate when the car already wears the proper 14-inch wheels and the goal is a sporty, era-appropriate radial presentation.
195/70R14 is a metric radial size that combines a 195-millimeter nominal section width with a 70-series profile on a 14-inch rim. For the 1985 Pontiac Fiero, it represents a different 14-inch fitment from the wider 215/60R14, so the correct sub-model and wheel setup matter before selecting it. The available option in this size is the Dunlop Sport Classic, offered as a blackwall radial and aimed at buyers who want a clean, understated look. This size deserves attention when the car is equipped for the 195/70R14 application and the priority is staying with the proper overall fitment rather than simply choosing any 14-inch tire.
Tire fitment on the 1985 Pontiac Fiero varies by sub-model, so identifying the exact trim is the first step before comparing tire options. That matters here because the covered cars use both 13-inch and 14-inch wheel packages, and the tire sizes are not interchangeable by name alone.

1985 Pontiac Fiero Base
The 1985 Pontiac Fiero Base uses the 185/80R13 radial fitment. That points the tire search toward 13-inch radial options and makes sidewall style a meaningful choice, especially if the car is being kept in a more restoration-oriented presentation.
The 1985 Pontiac Fiero GT uses the 215/60R14 radial size. Tire selection here centers on confirming the 14-inch wheel package and deciding whether the raised white letter performance look suits the car's intended appearance and use.
The 1985 Pontiac Fiero SE uses the 195/70R14 radial fitment. That makes wheel confirmation important first, then shifts the decision toward choosing a tire that preserves the proper 14-inch sizing and the overall character you want from the car.
The 1985 Pontiac Fiero Sport uses the same 185/80R13 radial size as the Base model. Once the 13-inch wheel setup is confirmed, the main choice becomes which available whitewall style and tire series best fits the car's visual direction.
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.

Owners shopping tires for a 1985 Pontiac Fiero usually need to sort out exact trim-level fitment, 13-inch versus 14-inch wheels, and the appearance differences between whitewall, blackwall, and raised white letter radial options.
Tire Size & Fitment
What tire size fits a 1985 Pontiac Fiero?
The 1985 Pontiac Fiero does not use one universal tire size across every sub-model. Base and Sport models use 185/80R13, the SE uses 195/70R14, and the GT uses 215/60R14. All three are radial sizes, but they differ in width, profile, and rim diameter.
The practical first step is matching the tire to the exact sub-model and the wheels currently on the car. A 13-inch Fiero setup and a 14-inch Fiero setup require different tires, and two different 14-inch sizes were used. On cars with replacement wheels, confirm the actual rim diameter before selecting a tire.
What size rim does a 1985 Pontiac Fiero use?
A 1985 Pontiac Fiero can use either a 13-inch or 14-inch rim, depending on the sub-model. The 185/80R13 fitment uses a 13-inch rim, while both 195/70R14 and 215/60R14 use 14-inch rims. Rim diameter is tied directly to the tire size on this vehicle.
That makes wheel confirmation especially important before ordering replacement tires. Two of the Fiero's correct sizes share the same 14-inch diameter but are still different fitments, so rim diameter alone is not enough. Checking both the sub-model and the wheel currently on the car will narrow the choice to the correct size.
Do all 1985 Pontiac Fiero sub-models use the same tire size?
No. The 1985 Pontiac Fiero uses different tire sizes across its sub-model range. Base and Sport models use 185/80R13, the SE uses 195/70R14, and the GT uses 215/60R14, so trim level directly affects tire selection.
That difference matters because the sizes are tied to different wheel diameters and different overall tire profiles. A buyer looking at a 14-inch Fiero still needs to know whether the car calls for 195/70R14 or 215/60R14. Checking the exact sub-model and verifying the wheels on the car prevents choosing a tire that is correct for a different Fiero configuration.
Choosing the Right Tire
What should I consider when choosing a tire for a 1985 Pontiac Fiero?
Start with the correct size for the exact 1985 Pontiac Fiero sub-model: 185/80R13, 195/70R14, or 215/60R14. After that, compare the available radial tire choices by wheel compatibility, sidewall style, and the look you want the car to have on the road or at shows.
For Base and Sport models, whitewall presentation is part of the decision because both narrow and wide whitewall options exist in 185/80R13. The GT's 215/60R14 fitment points toward a raised white letter look, while the SE's 195/70R14 is available as a blackwall Sport Classic. Matching the tire's appearance to the car's trim and current wheel setup usually leads to the clearest choice.
What sidewall styles are available for 1985 Pontiac Fiero tires?
Sidewall style depends on the size used by the specific 1985 Pontiac Fiero sub-model. In 185/80R13, available styles include narrow whitewall and wide whitewall. In 215/60R14, the available style is RWL, or raised white letters, and in 195/70R14 the available style is blackwall.
Those differences have a strong effect on the car's appearance even when the fitment is correct. Whitewalls tend to suit a more restoration-oriented or traditional presentation, blackwalls keep the look understated, and raised white letters give the GT-size tire a more overtly sporty 1980s character. Once size and wheel diameter are confirmed, sidewall style becomes one of the most visible selection choices.
What brands offer tires for the 1985 Pontiac Fiero?
1985 Pontiac Fiero tire options include Maxxis, BFGoodrich, Coker Classic, and Dunlop, depending on the size. The 185/80R13 fitment has the widest brand spread, while the 215/60R14 and 195/70R14 applications each point to a more specific product choice within their respective sizes.
Brand comparison only becomes useful after the correct size is established, since not every brand appears in every Fiero fitment. The 13-inch applications offer the broadest appearance choice through multiple brands and whitewall styles. By contrast, the 14-inch fitments are more size-specific, so the real decision is often whether the car is a GT or SE and which visual style suits that trim.
Restoration & Appearance
Which tire should I choose for a period-style 1985 Pontiac Fiero?
A period-style 1985 Pontiac Fiero tire starts with using the correct sub-model size and wheel diameter. Base and Sport models point toward 185/80R13, the SE uses 195/70R14, and the GT uses 215/60R14. Each size carries a different visual character, so the fitment itself shapes the car's stance and presentation.
From there, sidewall treatment becomes the main appearance decision. Whitewall choices in 185/80R13 create a more traditional look, the blackwall 195/70R14 keeps the SE restrained, and the GT's raised white letter option brings a stronger performance-era feel. Buyers pursuing exact originality should still compare those choices with marque references and the car's individual history.
How does tire construction affect the appearance of a restored 1985 Pontiac Fiero?
On the 1985 Pontiac Fiero, the primary fitments are radial tires in modern metric sizing. That means the restoration question is less about bias-ply versus radial appearance and more about choosing the correct size, profile, and sidewall treatment for the specific sub-model.
A tall 185/80R13 with whitewalls gives a very different visual result from a 215/60R14 with raised white letters, even though both are correct radial-type fitments for the Fiero range. Matching the tire's profile and sidewall to the trim helps preserve the car's intended period look. Size accuracy matters just as much as brand when appearance is a restoration priority.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1985 Pontiac Fiero?
Yes. A 1985 Pontiac Fiero can be affected by aftermarket wheels, suspension changes, altered ride height, or body modifications just like other collector-era cars. That is especially important here because the model already used more than one tire size and more than one rim diameter from the factory.
Even when a tire matches the original size for a Base, Sport, SE, or GT, the car should still be checked for wheel width, steering clearance, and fender clearance if changes have been made. A Fiero with replacement wheels may no longer match its original setup, so measuring the actual wheel diameter and reviewing the full chassis condition is a smart step.
What should I inspect before driving a 1985 Pontiac Fiero on new tires?
Before putting a 1985 Pontiac Fiero back into regular road use on new tires, inspect the wheels for damage, confirm that the tire size matches the car's sub-model and rim diameter, and make sure the tires are properly inflated. It is also wise to check for suspension wear, loose steering components, and uneven old-tire wear patterns.
Fresh tires can only perform as intended if the rest of the setup is sound. A quick look at brake condition, wheel fastener torque, and any signs of rubbing at full steering lock can prevent problems on the first drive. Cars that have been stored should also be checked for age-related issues such as seized components or air loss after installation.
How should tires on a collector 1985 Pontiac Fiero be maintained?
Collector-car tires on a 1985 Pontiac Fiero should be kept at appropriate pressure, inspected regularly for cracking, bulges, cuts, and uneven wear, and checked for air loss before the car goes back on the road. Because many Fieros are driven infrequently, condition and age matter as much as tread depth.
Storage conditions make a difference as well. Keeping the car away from prolonged sunlight, excess heat, moisture, and ozone sources helps protect the sidewalls and casing over time. It also helps to move the car periodically or adjust storage practices so the tires are not left sitting in one position for long intervals between drives.
