The 2002 Pontiac Firebird closed out a long-running chapter of Pontiac performance, and buyers still approach this final-year car with a clear sense of how they want it to look and drive. Whether the goal is a clean Base model, a Formula, or a more aggressive Trans Am setup, tire choice shapes both stance and road manners. The 2002 Pontiac Firebird uses radial fitments, but the exact size changes by sub-model and wheel package, spanning 16-inch and 17-inch applications. Available choices also vary by tire series and sidewall presentation, especially in 275/40R17. Getting the right tire starts with confirming the exact sub-model and wheel diameter on the car today.
Which Tire Size Is Right for The 2002 Pontiac Firebird
Three primary tire sizes apply to the 2002 Pontiac Firebird, and the correct one depends on the exact sub-model and wheel diameter. Two sizes use 16-inch rims, while the high-performance package applications move to a 17-inch rim, so the first step is confirming both the trim level and the wheels currently on the car before comparing tire choices.
In 235/55R16, the 235 identifies nominal section width in millimeters, 55 is the aspect ratio, R designates radial construction, and 16 is the rim diameter in inches. This is a modern metric radial fitment that suits the 2002 Firebird's standard 16-inch wheel application. It represents the straightforward stock-size decision for the Base sub-model rather than a broad performance-package fitment. The practical advantage of staying with this size is preserving the intended wheel diameter and general proportions before moving on to brand, tread character, and use expectations.
A 245/50R16 tire is slightly wider in metric section width than a 235, with a 50-series profile and a 16-inch rim diameter. This radial size belongs to specific 16-inch Firebird performance applications and keeps the tire decision centered on the correct wheel and sub-model rather than appearance alone. Available examples in this size come from BFGoodrich in the g-Force Comp 2 AS and g-Force Sport Comp 2 series, both in Blackwall form. Choosing this size starts with matching the vehicle's 16-inch setup, then comparing tire series and rim-width compatibility.
Fit(s): Formula w/Hi-Performance Pkg. and Trans Am w/Hi-Performance Pkg.
Construction: Radial|Rim: 17 in
The 275/40R17 code indicates a substantially wider metric radial with a 40-series profile on a 17-inch rim. On the 2002 Firebird, this size is tied to the high-performance package applications, making wheel diameter confirmation especially important before selection. Product choice is broader here, with BFGoodrich, M&H Racemaster, Nitto, Michelin, and Pro-Trac offerings, plus Blackwall, raised white letter, and Redline sidewall treatments across several tire series. This size makes sense when the car already carries the proper 17-inch wheel package and the owner wants to balance appearance, intended use, and specification details.
2002 Pontiac Firebird tire fitment varies by sub-model, so identifying the exact version matters before choosing a tire. The difference is not just width and profile, but also whether the car uses a 16-inch or 17-inch wheel setup.

2002 Pontiac Firebird Base
The 2002 Pontiac Firebird Base uses a 235/55R16 radial tire on a 16-inch wheel package. Tire selection here is mainly about staying with the proper metric radial size and then confirming that the car still retains its original wheel diameter.
The 2002 Pontiac Firebird Formula uses a 245/50R16 radial fitment, placing it in the 16-inch performance-oriented group rather than the Base setup. That makes series selection, rim-width compatibility, and the actual wheel configuration on the car more important than simply choosing by model name alone.
2002 Pontiac Firebird Formula w/Hi-Performance Pkg.
The 2002 Pontiac Firebird Formula w/Hi-Performance Pkg. uses a 275/40R17 radial tire and moves to a 17-inch wheel package. That changes both size and available product variety, so owners should confirm the car still carries the correct wheels before comparing sidewall style or tire series.
The 2002 Pontiac Firebird Trans Am uses the 245/50R16 radial size rather than the wider 17-inch high-performance package fitment. Tire choice therefore starts with the correct 16-inch application, then shifts to comparing the available BFGoodrich series within that size.
2002 Pontiac Firebird Trans Am w/Hi-Performance Pkg.
The 2002 Pontiac Firebird Trans Am w/Hi-Performance Pkg. uses 275/40R17 radial tires on a 17-inch setup. This opens up the widest product assortment on the page, so the key is matching the wheel package first and then selecting the sidewall treatment and tire type that suit the car's use.
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.

Available 2002 Pontiac Firebird tire choices center on 245/50R16 and 275/40R17 radial sizes, with BFGoodrich, Nitto, Michelin, M&H Racemaster, and Pro-Trac options. Buyers can compare tire series, Blackwall versus RWL or Redline sidewalls, and rim-width specifications depending on the size used on the car.
Common 2002 Pontiac Firebird tire questions usually come down to sub-model fitment, 16-inch versus 17-inch wheel setups, and how to choose among the available radial tire series and sidewall styles. The answers below focus on practical fitment and ownership checks for this exact model year.
Tire Size & Fitment
What tire size fits a 2002 Pontiac Firebird?
A 2002 Pontiac Firebird can use 235/55R16, 245/50R16, or 275/40R17, depending on the sub-model and wheel package. The Base model uses 235/55R16, the Formula and Trans Am use 245/50R16, and the Formula w/Hi-Performance Pkg. plus Trans Am w/Hi-Performance Pkg. use 275/40R17.
The important point is that these are not interchangeable primary fitments across every Firebird. Start by confirming the exact sub-model, then verify whether the car has 16-inch or 17-inch wheels today, especially if it has ever been modified or had wheels changed since new.
What size rim does a 2002 Pontiac Firebird use?
A 2002 Pontiac Firebird uses either a 16-inch or 17-inch rim, depending on the tire size and sub-model. The 235/55R16 and 245/50R16 fitments use 16-inch wheels, while the 275/40R17 fitment uses a 17-inch wheel.
That wheel diameter check should come before any tire purchase, because a 16-inch tire cannot be mounted on a 17-inch rim, and the reverse is also true. Looking at the existing tire size on the car and measuring the actual wheel setup is the safest way to confirm what belongs there.
Why does the 2002 Pontiac Firebird have more than one tire size?
The 2002 Pontiac Firebird has more than one tire size because tire fitment changes across the Base, Formula, Trans Am, and Hi-Performance Package versions. Pontiac used different wheel-and-tire combinations within the Firebird range, which is why the covered fitments span two rim diameters and three metric radial sizes.
That means the right choice depends on the exact version of the car rather than the Firebird name alone. A buyer should identify the sub-model first, then check whether the car still carries the same wheel diameter and general setup it was intended to use.
Choosing the Right Tire
What should I consider when choosing a tire for a 2002 Pontiac Firebird?
Start with the correct size for the exact 2002 Pontiac Firebird sub-model: 235/55R16, 245/50R16, or 275/40R17. After size is confirmed, compare radial construction details that matter to the car's use, including tire series, sidewall treatment, rim-width suitability, and product attributes such as general street or drag-oriented focus.
A Base car, a 16-inch Formula or Trans Am, and a Hi-Performance Package car do not present the same decision. It also helps to check whether the Firebird still has its intended wheels, since aftermarket changes can shift the practical tire options even when the model name remains the same.
What sidewall styles are available for 2002 Pontiac Firebird tires?
Available sidewall styles for 2002 Pontiac Firebird tires include Blackwall, RWL, and Redline, depending on the size and product selected. The broadest sidewall variety appears in 275/40R17, where Blackwall, raised white letter, and Redline choices are all represented.
Sidewall style mainly affects presentation, but it should always be chosen after the correct tire size and wheel diameter are confirmed. On a Firebird with 17-inch high-performance package fitment, sidewall treatment can meaningfully change the car's visual character without changing the need to match the proper size.
What brands offer tires for the 2002 Pontiac Firebird?
Tires for the 2002 Pontiac Firebird are available from BFGoodrich, M&H Racemaster, Nitto, Michelin, and Pro-Trac across the supported 245/50R16 and 275/40R17 sizes. BFGoodrich appears in both supported product sizes, while the 275/40R17 fitment opens up the broadest brand mix.
Brand alone should not drive the decision. Once the correct Firebird size is confirmed, compare the tire series each brand offers, the sidewall style available in that size, and any rim-width or load details that affect how the tire suits the car's intended use.
Restoration & Appearance
Which tire should I choose for a period-style 2002 Pontiac Firebird?
A period-style 2002 Pontiac Firebird should first stay with the correct original-type size family for its exact sub-model, whether that is 235/55R16, 245/50R16, or 275/40R17. Because this Firebird is a late-production modern muscle car, the appearance decision usually centers more on sidewall treatment and wheel package than on vintage construction choices.
For a cleaner modern look, Blackwall options keep the presentation restrained. A 17-inch car with Pro-Trac choices can also move toward a more visual statement with RWL or Redline styling, but exact originality should still be checked against marque references and the car's specific equipment.
How does tire construction affect the appearance of a restored 2002 Pontiac Firebird?
On a restored 2002 Pontiac Firebird, tire construction is less about bias-ply versus radial appearance and more about preserving the proper modern radial stance for the correct wheel package. All covered primary fitments for this model are radial, so the visible differences come mainly from size, profile, and sidewall style.
That makes wheel diameter especially important to the finished look. A Firebird intended for a stock-style presentation should keep the correct 16-inch or 17-inch fitment for its sub-model, then use sidewall treatment and tread style to support the appearance without drifting into the wrong overall proportion.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2002 Pontiac Firebird?
Yes, modifications can affect tire fitment on a 2002 Pontiac Firebird even when the tire size sounds correct on paper. Aftermarket wheels, altered offsets, lowered suspension, spring changes, brake upgrades, or body modifications can all change how a 235/55R16, 245/50R16, or 275/40R17 tire sits in the wheel opening.
A Firebird that no longer has its original wheel setup should be measured rather than assumed. Check wheel diameter and width first, then confirm steering clearance, inner clearance, and fender clearance before settling on a replacement tire in the size that matches the car's current configuration.
What should I inspect before driving a 2002 Pontiac Firebird on new tires?
Before driving a 2002 Pontiac Firebird on new tires, inspect the wheels for damage, confirm the tire size matches the sub-model and rim diameter, and make sure the tires are mounted and inflated correctly. It also helps to look over valve stems, lug torque, and general suspension condition before the first road test.
A short initial drive should be used to check for rubbing, vibration, pulling, or unusual contact at full steering lock. Those steps matter even more on a Firebird with wider 17-inch fitment or any aftermarket wheel change, where clearance can differ from one car to another.
How should tires on a collector 2002 Pontiac Firebird be maintained?
Tires on a collector 2002 Pontiac Firebird should be maintained with regular pressure checks, visual inspections, and periodic assessment for cracking, cuts, bulges, uneven wear, or slow air loss. Low-mileage cars can still develop tire age issues, so condition matters just as much as tread depth on a vehicle that spends time in storage.
Storage practices make a difference as well. Keeping the car away from prolonged sunlight, heat, moisture, and ozone sources helps preserve the tires, and moving or driving the car occasionally can help avoid long-term flat spotting during extended periods of inactivity.
