The 1986 Pontiac Firebird sits deep in the third-generation F-body era, when Pontiac blended wedge-shaped styling, available aero details, and V8 attitude into a distinctly 1980s American sport coupe. That matters when choosing tires, because this exact model year uses several radial sizes across different Firebird sub-models, wheel packages, and rim diameters. The fitment range runs from 195/75R14 through 245/50R16 and 235/60R15, with choices that include whitewalls, redlines, raised white letters, and blackwall performance styles. The key is matching the correct size to the exact sub-model and wheel setup, then choosing the tire look and series that suit either restoration-minded presentation or regular road use.
Which Tire Size Is Right for The 1986 Pontiac Firebird
Five tire sizes apply to the 1986 Pontiac Firebird, and they vary by sub-model and wheel package across 14-inch, 15-inch, and 16-inch rims. The first step is confirming the exact Firebird sub-model and actual wheel diameter on the car, because several trims share similar names while using different radial sizes. Once that is settled, the decision shifts to sidewall style, tire series, and the overall look you want.
195/75R14 is a metric radial size: 195 is the nominal section width in millimeters, 75 is the aspect ratio, R identifies radial construction, and 14 is the rim diameter in inches. On the 1986 Pontiac Firebird, this size suits the more standard 14-inch wheel fitment rather than the wider performance-oriented packages. Available choices include Coker Classic, Tornel, Maxxis, and Travelstar offerings, with wide whitewall and narrow whitewall sidewall treatments. This size makes the most sense when the car retains its original-style 14-inch wheel setup and the goal is preserving the correct overall fitment approach.
Fit(s): S/E, S/E w/aluminum wheels, Trans Am, and Trans Am w/aluminum wheels
Construction: Radial|Rim: 14 in
205/70R14 is a metric radial with a 205-millimeter nominal section width, a 70-series profile, and a 14-inch rim requirement. Within the 1986 Pontiac Firebird range, this size appears on specific S/E and Trans Am configurations, so it should not be treated as a universal fitment for every Firebird. Product choices include BFGoodrich, Maxxis, and Michelin, with blackwall, redline, dual-redline, narrow whitewall, and raised white letter styles depending on the tire series. It is a useful size to evaluate carefully if the car has a 14-inch sport-oriented setup and appearance matters as much as size accuracy.
Fit(s): S/E, S/E w/aluminum wheels, Trans Am, and Trans Am w/aluminum wheels
Construction: Radial|Rim: 15 in
215/65R15 is a metric radial size where 215 is the nominal section width in millimeters, 65 is the aspect ratio, and 15 is the rim diameter. For the 1986 Pontiac Firebird, this size belongs to certain S/E and Trans Am applications that move to a 15-inch wheel while staying within the factory-style radial fitment range. Available options span Goodyear, Cooper, and BFGoodrich lines, with OWL, RWL, redline, and wide whitewall treatments across several tire series. This size deserves close attention when the car already wears 15-inch wheels and the buyer wants to balance the proper fitment with a specific visual theme.
245/50R16 is a wider metric radial size with a 245-millimeter nominal section width, a 50-series profile, and a 16-inch rim. On the 1986 Pontiac Firebird, it belongs only to certain S/E configurations, making wheel confirmation especially important before considering it. The available choices stay focused on BFGoodrich blackwall performance tires in the g-Force Comp 2 AS and g-Force Sport Comp 2 series, both built around the larger 16-inch fitment. This size is best evaluated when the car already has the correct 16-inch wheel package and the intended look leans more toward later-1980s performance styling than traditional sidewall detail.
Fit(s): Trans Am V8 and Trans Am V8 w/aluminum wheels
Construction: Radial|Rim: 15 in
235/60R15 is a metric radial size with a 235-millimeter nominal section width, a 60-series profile, and a 15-inch rim diameter. In the 1986 Pontiac Firebird lineup, this size is tied to Trans Am V8 applications, so it should be matched to that specific configuration rather than treated as a general 15-inch Firebird fitment. Product options include BFGoodrich, Cooper, and M&H Racemaster, with blackwall and raised white letter presentations across street and drag-oriented tire series. This size is worth choosing only after confirming the exact Trans Am V8 wheel setup and deciding whether the car's use is mostly show, street, or specialty performance.
Sub-model fitment matters on the 1986 Pontiac Firebird because tire size changes across the lineup and spans three rim diameters. Similar trim names can share some sizes, but the correct tire still depends on identifying the exact sub-model and confirming the wheel package on the car.

1986 Pontiac Firebird Base
The 1986 Pontiac Firebird Base uses a single radial fitment on a 14-inch wheel, making its tire selection more straightforward than some other Firebird variants. The main choice becomes finding the right sidewall style and tire series for the car's appearance while staying with the proper size category.
The 1986 Pontiac Firebird S/E can use more than one radial tire size, so this sub-model requires careful wheel confirmation before any tire is selected. Once rim diameter is verified, the buyer can focus on whether the goal is a traditional sidewall treatment or a more performance-oriented look.
The 1986 Pontiac Firebird S/E w/aluminum wheels shares the same multi-size radial fitment pattern seen on other S/E applications. That makes actual wheel diameter the first checkpoint, followed by choosing among whitewall, redline, raised white letter, or blackwall styles where available in the correct size.
The 1986 Pontiac Firebird Trans Am uses one of two radial sizes depending on the wheel setup, so the tire decision starts with confirming whether the car carries the 14-inch or 15-inch fitment. After that, the selection can be narrowed by tire series and sidewall presentation to match the car's intended road use and visual character.
The 1986 Pontiac Firebird Trans Am V8 uses a distinct 15-inch radial fitment that separates it from the smaller-size Trans Am applications. That gives the buyer a clear starting point, but it still helps to compare sidewall style, intended use, and wheel-width compatibility before settling on a tire.
1986 Pontiac Firebird Trans Am V8 w/aluminum wheels
The 1986 Pontiac Firebird Trans Am V8 w/aluminum wheels uses the same principal radial size as the standard Trans Am V8. Tire selection is less about sorting through multiple fitments and more about choosing the right series and sidewall style for the wheel setup already on the car.
The 1986 Pontiac Firebird Trans Am w/aluminum wheels follows the same two-size radial pattern used on other Trans Am applications in this model year. Checking the actual rim diameter is essential first, because the correct tire choice depends on matching the wheel before comparing available tire styles.
The 1986 Pontiac Firebird w/aluminum wheels uses the same straightforward 14-inch radial fitment as the standard Base application. That simplifies size selection, leaving sidewall appearance and tire-series preference as the more meaningful buying decisions.
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 1986 Pontiac Firebird tire questions usually come down to the exact size for the sub-model, the correct rim diameter, and how the available sidewall and tire-series choices affect the car’s look and use. The answers below focus on fitment first, then selection and road-use checks.
Tire Size & Fitment
What tire size fits a 1986 Pontiac Firebird?
A 1986 Pontiac Firebird can use 195/75R14, 205/70R14, 215/65R15, 245/50R16, or 235/60R15, depending on the exact sub-model and wheel package. All of these are radial tire sizes, but they do not apply across the entire Firebird lineup in the same way.
The right starting point is the exact trim and the actual wheel diameter on the car. A Base model uses a different fitment path than an S/E or Trans Am V8, and aluminum-wheel applications can still share or overlap sizes, so the safest approach is matching the tire to the specific configuration before comparing brands or sidewall styles.
What size rim does a 1986 Pontiac Firebird use?
The 1986 Pontiac Firebird uses 14-inch, 15-inch, and 16-inch rims across its various sub-models. Tire sizes are matched to those wheel diameters: 195/75R14 and 205/70R14 fit 14-inch rims, 215/65R15 and 235/60R15 fit 15-inch rims, and 245/50R16 fits a 16-inch rim.
Rim diameter should be confirmed before anything else, especially on a car that may have changed wheels over time. The tire size must match the wheel diameter exactly, and a Firebird that now wears aftermarket wheels or a different factory-style package may no longer follow the original sub-model pattern without verification.
Why does the 1986 Pontiac Firebird have more than one tire size?
The 1986 Pontiac Firebird has more than one tire size because the lineup includes different sub-models and wheel packages. Base, S/E, and Trans Am applications do not all use the same rim diameter or the same width-and-profile combination, so Pontiac fitment varied within the model range.
That variation means tire choice is not just a matter of the model year and nameplate. A buyer should confirm the exact sub-model, then check whether the car still carries its original wheel size or has been changed, because selecting by appearance alone can lead to the wrong diameter or the wrong fitment category.
Choosing the Right Tire
What should I consider when choosing a 1986 Pontiac Firebird tire?
Start with the exact tire size that belongs on the specific 1986 Pontiac Firebird sub-model and wheel diameter. From there, compare radial tire series, sidewall style, and wheel-width compatibility, since the available products range from traditional whitewall and redline designs to blackwall and raised white letter performance-oriented choices.
The best selection process depends on how the car is used and presented. A restoration-minded Firebird may call for a different visual treatment than a driver or a more aggressive street build, and cars with changed wheels should also have clearance and wheel-width details checked before a final tire decision is made.
What sidewall styles are available for 1986 Pontiac Firebird tires?
Sidewall styles available across 1986 Pontiac Firebird tire sizes include wide whitewall, narrow whitewall, redline, dual-redline, RWL, OWL, and blackwall. The exact choices depend on the size, since a 14-inch fitment can offer different appearance options than a 15-inch or 16-inch Firebird application.
That variety lets the tire play a major role in the car’s final look. Whitewalls and redlines create a more restoration-oriented presentation, while RWL, OWL, and blackwall styles lean toward the sportier 1980s character many Firebird owners want, so the visual goal should be settled only after the correct size is confirmed.
What brands offer tires for the 1986 Pontiac Firebird?
Brands available for 1986 Pontiac Firebird tire sizes include Coker Classic, Tornel, Maxxis, Travelstar, BFGoodrich, Michelin, Goodyear, Cooper, and M&H Racemaster. The brand mix changes by size, so one Firebird fitment may have mostly classic-style choices while another leans more heavily toward performance-oriented radial offerings.
Brand comparison is most useful after narrowing the search to the exact size. At that point, the meaningful differences are usually tire series, sidewall presentation, load specification, and intended use rather than the name on the sidewall alone, especially on a car with several possible factory-style fitment paths.
Restoration & Appearance
Which tire should I choose for a period-style 1986 Pontiac Firebird?
A period-style 1986 Pontiac Firebird tire starts with the exact size used by the car’s sub-model and wheel diameter, then narrows to a sidewall and tire series that match the look you want. Depending on size, that can mean whitewall, redline, raised white letter, or blackwall radial choices.
A Base Firebird often points toward a different visual treatment than a Trans Am or S/E with larger wheels, so style should follow fitment rather than override it. When originality matters at a very high level, marque references and vehicle-specific history are worth checking before choosing a particular stripe, letter, or whitewall presentation.
How does tire construction affect the appearance of a restored 1986 Pontiac Firebird?
On a 1986 Pontiac Firebird, construction is less of a debate than on earlier collector cars because the primary fitments are already radial. Appearance is shaped more by the tire’s profile, sidewall style, and series character, with options ranging from classic whitewalls and redlines to later-style raised white letters and blackwalls.
That means a restored Firebird can look noticeably different even when the tire size is correct. A buyer aiming for a cleaner base-model presentation may prefer a more restrained sidewall, while a sportier S/E or Trans Am build may lean toward bolder lettering or blackwall performance styling in the proper size and rim category.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1986 Pontiac Firebird?
Yes. A 1986 Pontiac Firebird with aftermarket wheels, suspension changes, altered ride height, or body modifications may no longer follow the original size pattern exactly. That matters even more here because this model year already uses several factory-type sizes across 14-inch, 15-inch, and 16-inch wheel applications.
Wheel diameter is only the first check. Wheel width, offset, steering clearance, and fender room can all change the outcome once a car has been modified, so the tire should be matched to the Firebird’s current setup rather than assumed from the badge or trim name alone.
What should I inspect before driving a 1986 Pontiac Firebird on new tires?
Before driving a 1986 Pontiac Firebird on new tires, inspect wheel condition, lug hardware, valve stems, and overall tire pressure. It also helps to confirm that the installed size matches the wheel diameter and that the tire clears suspension and body components through normal steering and ride movement.
Collector-era cars often sit longer than modern daily drivers, so the rest of the chassis deserves attention too. A quick check of alignment, shocks, steering parts, and brake condition helps the new tires work as intended and can prevent wear or drivability issues that might be blamed on the tires themselves.
What should I check before a longer drive in a 1986 Pontiac Firebird?
Before a longer drive, confirm tire pressure, tread condition, and sidewall health on the 1986 Pontiac Firebird. Look for cracking, bulges, cuts, or signs of air loss, and make sure the tire size on the car still matches the wheel and sub-model setup the vehicle is using.
Longer highway use places more demand on a collector-era car than short local trips. It is wise to recheck the spare if one is carried, inspect for uneven wear that may point to alignment issues, and give extra attention to any Firebird that has spent extended time in storage or sees only occasional use.
