The 1986 Pontiac Sunbird came from an era when compact American cars were balancing everyday practicality with sharper styling and trim-specific personality. A Sunbird from this period can range from a straightforward commuter to a sportier GT, and the tire fitment reflects those differences. The 1986 Pontiac Sunbird uses radial tires, but the exact size changes by sub-model, with both 13-inch and 14-inch rim applications in the lineup. Available choices include whitewall and raised white letter presentations across BFGoodrich and Maxxis offerings. For a clean replacement, the first step is matching the exact sub-model and wheel diameter before comparing appearance, rim-width compatibility, and overall driving intent.
Which Tire Size Is Right for The 1986 Pontiac Sunbird
Three tire sizes apply to the 1986 Pontiac Sunbird, and they are tied to specific sub-models and wheel diameters. Two sizes fit 13-inch rims, while one sportier application uses a 14-inch rim, so the first step is confirming whether the car is a Base, SE, GT, or Handling Package model. Once that is settled, the real choice becomes sidewall style, tire series, and the overall look you want from the replacement tire.
175/80R13 is a metric radial size in which 175 is the nominal section width in millimeters, 80 is the aspect ratio, R identifies radial construction, and 13 is the rim diameter in inches. On the 1986 Pontiac Sunbird, this size suits 13-inch wheel applications and keeps the replacement in the same general fitment family intended for the Base and SE models. Available choices include Maxxis and BFGoodrich, with both narrow whitewall and wide whitewall presentations. This size makes the most sense when the car retains its stock-type 13-inch wheel setup and the goal is either a clean traditional whitewall look or a more understated classic radial appearance.
215/60R14 is a metric radial size where 215 gives the nominal section width in millimeters, 60 is the aspect ratio, R means radial construction, and 14 identifies the rim diameter. On the 1986 Pontiac Sunbird, this size belongs to the GT application and stands apart from the 13-inch fitments used elsewhere in the model range. The available product uses BFGoodrich's Radial T/A series with raised white letter sidewalls, giving this size a distinctly sport-oriented visual character. This is the size to evaluate when the car has the GT wheel setup and you want to preserve the correct 14-inch fitment rather than substitute from a different Sunbird sub-model.
195/70R13 is a metric radial size that uses a 195-millimeter nominal section width, a 70-series profile, radial construction, and a 13-inch rim diameter. For the 1986 Pontiac Sunbird, this size is associated with the Handling Package and represents a different 13-inch fitment than the 175/80R13 used on other versions. The available choice is a BFGoodrich Silvertown Radial with a narrow whitewall, giving the size a balanced mix of traditional appearance and modern radial construction. This fitment deserves a closer look when a Sunbird has the Handling Package, since matching the package-specific tire size is more important than assuming every 13-inch Sunbird uses the same tire.
Sub-model fitment matters on the 1986 Pontiac Sunbird because tire size changes across the lineup. Base and SE models share one size, while the GT and Handling Package versions use different fitments, making the exact trim and wheel diameter the key starting points.

1986 Pontiac Sunbird Base
The 1986 Pontiac Sunbird Base uses the 175/80R13 radial tire size on a 13-inch rim. That keeps tire selection focused on choosing between available whitewall styles and tire series rather than sorting through multiple primary sizes.
The 1986 Pontiac Sunbird GT uses the 215/60R14 radial size, which sets it apart from the 13-inch Sunbird applications. Tire selection here starts with confirming the 14-inch wheel setup, then choosing the sidewall presentation and tire series that best suit the car's sportier trim.
The 1986 Pontiac Sunbird SE shares the 175/80R13 radial fitment with the Base model. That makes the decision largely about appearance and product character, especially if the goal is to keep a period-style whitewall presentation on a stock-type 13-inch wheel.
The 1986 Pontiac Sunbird w/Handling Pkg. uses the 195/70R13 radial tire size rather than the 175/80R13 found on other 13-inch versions. That difference is important when replacing tires, since the package-specific fitment should be matched before comparing sidewall style or tire series.
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.
Best 1986 Pontiac Sunbird Tires for Sale
Available 1986 Pontiac Sunbird tires center on radial replacements from BFGoodrich and Maxxis. Depending on the exact size, the product grid includes Silvertown Radial, Classic Whitewall MA-1, and Radial T/A options with narrow whitewall, wide whitewall, or raised white letter sidewall treatments.
Common 1986 Pontiac Sunbird tire questions usually come down to matching the correct sub-model, confirming 13-inch versus 14-inch wheel fitment, and choosing between the available radial sizes, sidewall styles, and product series.
Tire Size & Fitment
What tire size fits a 1986 Pontiac Sunbird?
The 1986 Pontiac Sunbird uses three different radial tire sizes, depending on sub-model. Base and SE models use 175/80R13, the GT uses 215/60R14, and the Sunbird w/Handling Pkg. uses 195/70R13. Those are separate primary fitments, not interchangeable assumptions across the whole Sunbird lineup.
The most important next step is identifying the exact sub-model and checking the wheel diameter already on the car. A 13-inch Sunbird still may not use the same tire as another 13-inch version, so matching the trim and wheel setup before choosing a replacement helps avoid buying a tire that belongs to a different Sunbird configuration.
What size rim does a 1986 Pontiac Sunbird use?
A 1986 Pontiac Sunbird uses either a 13-inch or 14-inch rim, depending on sub-model. The Base and SE use 13-inch rims with 175/80R13 tires, the Handling Package also uses a 13-inch rim with 195/70R13 tires, and the GT uses a 14-inch rim with 215/60R14 tires.
Rim diameter should be confirmed before anything else because the Sunbird line does not use one wheel size across all versions. It also helps to verify wheel width, especially if the car has aftermarket wheels or an older wheel swap, since the available tires carry their own rim-width ranges that should be compared before installation.
Do all 1986 Pontiac Sunbird sub-models use the same tire size?
No. The 1986 Pontiac Sunbird has trim-specific tire fitments. Base and SE models share 175/80R13, the GT uses 215/60R14, and the Sunbird w/Handling Pkg. uses 195/70R13. Even though two of those sizes fit 13-inch rims, they are still distinct tire sizes with different width and profile dimensions.
That means a replacement should be chosen by exact sub-model rather than by make and model alone. Looking at the tire sidewall already on the car and confirming the wheel diameter can help, but it is still wise to make sure the car has not been changed from its original wheel setup before selecting a tire from the available Sunbird choices.
Choosing the Right Tire
What should I consider when choosing a 1986 Pontiac Sunbird tire?
Start with the exact tire size that matches the Sunbird's sub-model and wheel diameter, since this car uses more than one fitment. After size is confirmed, compare the available tire series, sidewall style, rim-width range, and load specification within that size so the replacement matches both the car and the intended look.
A Base or SE owner may be deciding between narrow whitewall and wide whitewall presentation in 175/80R13, while a GT owner is focused on the 215/60R14 raised white letter option. Handling Package cars need the 195/70R13 fitment first, then a product choice that works with the wheel and the kind of driving the car actually sees.
What sidewall styles are available for 1986 Pontiac Sunbird tires?
The available sidewall styles for a 1986 Pontiac Sunbird include narrow whitewall, wide whitewall, and RWL, or raised white letter, depending on tire size. The 175/80R13 options include both narrow and wide whitewalls, the 195/70R13 option uses a narrow whitewall, and the 215/60R14 GT fitment is offered in raised white letter form.
Sidewall choice affects the car's presentation as much as the tire size itself. Whitewalls tend to suit a more traditional, everyday 1980s compact look, while raised white letters bring a stronger performance appearance to the GT-style fitment. The key is choosing the sidewall style within the correct size instead of picking an appearance treatment from another Sunbird application.
What brands offer tires for the 1986 Pontiac Sunbird?
1986 Pontiac Sunbird tire options are available from BFGoodrich and Maxxis. BFGoodrich appears across all three Sunbird sizes offered here, while Maxxis is available in the 175/80R13 fitment. Tire series include Silvertown Radial, Classic Whitewall MA-1, and Radial T/A, depending on the exact size and sidewall style.
Brand should be compared along with size, tire series, and visual treatment rather than as a standalone decision. A 175/80R13 buyer has more than one brand and whitewall presentation to compare, while the GT's 215/60R14 fitment is centered on a single raised white letter BFGoodrich option. Matching the sub-model still comes before comparing brand names.
Restoration & Appearance
Which tire should I choose for a period-style 1986 Pontiac Sunbird?
A period-style choice starts with the correct size for the exact 1986 Pontiac Sunbird sub-model. Base and SE cars use 175/80R13, the GT uses 215/60R14, and the Handling Package uses 195/70R13. Once that is set, the visual direction can shift toward whitewall or raised white letter styling depending on how the car is being presented.
Whitewall options in the 13-inch sizes give the Sunbird a more traditional replacement look, while the GT's raised white letter tire supports a sportier 1980s appearance. Exact originality can depend on trim, wheel choice, and how the car was equipped when new, so restoration-focused owners may also want to compare against period photos or marque-specific references.
How does tire construction affect the appearance of a restored 1986 Pontiac Sunbird?
On the 1986 Pontiac Sunbird, the primary fitments are all radial, so construction choice is less about bias-ply versus radial appearance and more about selecting the right size and sidewall treatment. The visual difference comes from whether the tire carries a narrow whitewall, wide whitewall, or raised white letter presentation.
That matters because the tire sidewall helps define how the finished car reads at a glance. A restored Base or SE can take on a distinctly different character with a whitewall, while the GT's 215/60R14 raised white letter style pushes the look toward factory-era sport compact cues. Size accuracy still has to come first for the appearance to look right.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1986 Pontiac Sunbird?
Yes. Wheel changes, suspension work, lowering, or brake and hub swaps can affect tire fitment on a 1986 Pontiac Sunbird even when the tire size matches a known Sunbird application. This matters because the car already uses more than one factory-style size, including both 13-inch and 14-inch wheel diameters depending on sub-model.
A Sunbird with aftermarket wheels should have both wheel diameter and wheel width checked before a tire is selected. Clearance at the fender, inner wheelhouse, and steering range also deserves attention, especially when using a different wheel than the car originally carried. Trim-specific fitment should be treated as a starting point, not a substitute for a physical inspection.
What should I inspect before driving a 1986 Pontiac Sunbird on new tires?
Before road use, inspect the wheel condition, verify the tire size matches the Sunbird's exact sub-model, and check that inflation is appropriate for the tire being used. It is also smart to look over the valve stems, lug hardware, and the basic condition of the suspension and steering so the new tires are not being installed on worn supporting parts.
A short test drive should include attention to vibration, pulling, rubbing, or any sign that the tire is contacting the body or suspension. Collector and low-mile cars deserve extra caution because long storage can hide problems such as seized brakes, dry rubber parts, or alignment issues. Catching those items early helps the new tires wear and behave as intended.
How often should tires on a 1986 Pontiac Sunbird be inspected?
Tires on a 1986 Pontiac Sunbird should be inspected regularly, and collector-driven cars deserve checks even when mileage stays low. Look for uneven tread wear, cracking, bulges, cuts, air loss, and signs of rubbing. Cars that sit for long periods can develop tire concerns from age and storage conditions long before the tread looks used up.
Monthly pressure checks are a sensible habit, with a closer visual inspection before longer drives or after the car has been parked for an extended time. It also helps to inspect the wheels and suspension at the same time, since alignment or worn component issues can show up in the tires first. Early attention is especially useful on trim-specific Sunbird fitments.
