The 2001 Pontiac Firebird belongs to the final stretch of fourth-generation F-body production, a period when Pontiac still blended long-hood muscle-car attitude with modern road manners. Buyers looking at one today are often balancing factory-style fitment, street performance, and the visual character that suits the car’s trim level. Tire fitment on the 2001 Pontiac Firebird stays firmly in radial territory, but the exact size depends on the sub-model and whether the car carries the Hi-Performance Package. That opens the door to choices in 16-inch and 17-inch fitment, along with differences in tire series and sidewall presentation. The right selection starts with confirming the exact Firebird configuration and wheel setup already on the car.
Which Tire Size Is Right for The 2001 Pontiac Firebird
The 2001 Pontiac Firebird uses four primary tire sizes, and the correct one depends on the exact sub-model and wheel package. All of them are radial sizes, but they are split between 16-inch and 17-inch rims, so the first step is confirming both the specific Firebird trim and the wheel diameter currently on the car before comparing tire options.
215/60R16 is a metric radial size where 215 identifies the section width in millimeters, 60 is the aspect ratio, R indicates radial construction, and 16 is the wheel diameter in inches. On the 2001 Pontiac Firebird, this size is part of the Base model fitment range and reflects a straightforward modern radial setup. It sits within the same 16-inch wheel family as other Firebird sizes, but it should not be assumed to apply across every trim. This size matters most when preserving the intended wheel-and-tire relationship on a Base car that was equipped this way.
235/55R16 is a metric radial size with a 235-millimeter nominal section width, a 55-series profile, radial construction, and a 16-inch rim diameter. For the 2001 Pontiac Firebird, this size also belongs to the Base model fitment picture, making wheel confirmation especially important before ordering. Compared with other Firebird sizes, it remains a 16-inch application but carries a different width and profile balance. This is the size to evaluate when the car is a Base model and the existing wheel setup points to the wider 16-inch fitment rather than the narrower alternative.
245/50R16 is a metric radial size in which 245 is the section width in millimeters, 50 is the aspect ratio, R marks radial construction, and 16 is the rim diameter. On the 2001 Pontiac Firebird, this size is used on Formula and Trans Am applications, so it represents a different fitment path than the Base model sizes. Available products in this size come from BFGoodrich in blackwall form, including g-Force Comp 2 AS and g-Force Sport Comp 2 series choices. It is the right size to evaluate when the car carries the 16-inch Formula or Trans Am wheel setup and you want to compare series within that fitment.
Fit(s): Formula w/Hi-Performance Pkg. and Trans Am w/Hi-Performance Pkg.
Construction: Radial|Rim: 17 in
275/40R17 is a metric radial size with a 275-millimeter nominal width, a 40-series profile, radial construction, and a 17-inch wheel diameter. On the 2001 Pontiac Firebird, this size belongs to Formula and Trans Am models equipped with the Hi-Performance Package, making the 17-inch rim diameter a key confirmation point. Product selection is broader here, with BFGoodrich, Nitto, Michelin, M&H Racemaster, and Pro-Trac offerings across blackwall, raised white letter, and redline sidewall styles. This size deserves careful comparison when the car already has the high-performance wheel package and appearance choice matters alongside fitment.
Sub-model fitment on the 2001 Pontiac Firebird is not one-size-fits-all. Tire selection depends on identifying whether the car is a Base, Formula, or Trans Am, and whether it carries the Hi-Performance Package that moves the car to a 17-inch wheel and tire combination.

2001 Pontiac Firebird Base
The 2001 Pontiac Firebird Base uses one of two 16-inch radial sizes, so this trim calls for a closer look at the wheel-and-tire setup already on the car. Confirming which 16-inch fitment is present is the key step before comparing replacement tires or preserving the car’s existing stance.
The 2001 Pontiac Firebird Formula uses a 245/50R16 radial fitment in standard form. That keeps the decision focused on choosing among the available 16-inch tire options in the correct size and matching them to the car’s intended street use and appearance.
2001 Pontiac Firebird Formula w/Hi-Performance Pkg.
The 2001 Pontiac Firebird Formula with Hi-Performance Package uses a 275/40R17 radial setup. That package changes both size and wheel diameter, so tire choice starts with confirming the 17-inch package and then comparing the broader range of available sidewall and tire-series options.
The 2001 Pontiac Firebird Trans Am uses a 245/50R16 radial tire in its standard fitment. This makes product selection more about comparing tire series and rim-width suitability within the correct 16-inch size than about sorting through multiple primary size possibilities.
2001 Pontiac Firebird Trans Am w/Hi-Performance Pkg.
The 2001 Pontiac Firebird Trans Am with Hi-Performance Package uses a 275/40R17 radial fitment. That puts the focus on the 17-inch high-performance setup, where sidewall presentation, tire series, and wheel compatibility become the main points to review before choosing a replacement.
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 2001 Pontiac Firebird Tires for Sale
Available product choices center on 245/50R16 and 275/40R17 radial fitments. Buyers can compare BFGoodrich, Nitto, Michelin, M&H Racemaster, and Pro-Trac options across blackwall, raised white letter, and redline styles, along with tire-series and rim-width differences that matter to the car’s setup.
Firebird owners usually need to sort out exact tire size by sub-model, 16-inch versus 17-inch wheel fitment, and which available radial tire best suits the car’s use and appearance. These answers focus on that decision-making process for the 2001 Pontiac Firebird.
Tire Size & Fitment
What tire size fits a 2001 Pontiac Firebird?
A 2001 Pontiac Firebird can use 215/60R16, 235/55R16, 245/50R16, or 275/40R17, depending on the sub-model and wheel package. Base models use the 215/60R16 or 235/55R16 range, while Formula and Trans Am models use 245/50R16 in standard form and 275/40R17 with the Hi-Performance Package.
That means the right size is tied to the exact version of the car rather than the Firebird name alone. Checking the trim level, confirming whether the car has the Hi-Performance Package, and verifying the actual wheel diameter on the vehicle are the best first steps, especially if wheels or tires may have been changed over the years.
What size rim does a 2001 Pontiac Firebird use?
The 2001 Pontiac Firebird uses either a 16-inch or 17-inch rim, depending on the tire size and sub-model. The 215/60R16, 235/55R16, and 245/50R16 sizes are built around a 16-inch wheel, while the 275/40R17 size uses a 17-inch wheel.
Rim diameter should be confirmed before anything else because a 16-inch tire and a 17-inch tire are not interchangeable. Once the diameter is established, it becomes much easier to narrow the decision to the correct Firebird fitment and then compare tire series, sidewall style, and rim-width suitability within that exact size.
Do all 2001 Pontiac Firebird sub-models use the same tire size?
No, the 2001 Pontiac Firebird does not use one tire size across every sub-model. Base models use 215/60R16 or 235/55R16, Formula and Trans Am models use 245/50R16, and Hi-Performance Package versions of the Formula and Trans Am move to 275/40R17.
That variation is why sub-model identification matters so much on this page. A tire that matches one Firebird configuration may have the wrong width, profile, or wheel diameter for another, so the safest path is to verify the trim and wheel setup first, then compare products only within the size tied to that exact car.
Choosing the Right Tire
What should I consider when choosing a 245/50R16 tire for a 2001 Pontiac Firebird?
Start with the correct application, since 245/50R16 belongs to the 2001 Pontiac Firebird Formula and Trans Am in standard form. Available choices in this size include BFGoodrich options in blackwall form, with g-Force Comp 2 AS and g-Force Sport Comp 2 series offerings built around the same basic fitment.
The real decision comes down to matching the tire to the car’s use and wheel setup. Compare the rim-width range, construction details, and any load figures that matter to your application, then choose the tire series that best aligns with how the Firebird is driven and how original or performance-oriented you want the finished presentation to look.
What sidewall styles are available for 2001 Pontiac Firebird tires?
Sidewall style depends on the size being considered, and the strongest variety appears in 275/40R17. That size is available in blackwall, raised white letter, and redline treatments, while the 245/50R16 options shown here are blackwall tires.
Appearance can change the character of a Firebird almost as much as the wheel itself, so sidewall style should be chosen after the correct size is confirmed. A blackwall keeps the look restrained, while raised white letter or redline options add more visual emphasis, particularly on Hi-Performance Package cars using the 17-inch setup.
What brands offer tires for the 2001 Pontiac Firebird?
The available tire brands for the 2001 Pontiac Firebird include BFGoodrich for 245/50R16 and BFGoodrich, Nitto, Michelin, M&H Racemaster, and Pro-Trac for 275/40R17. Those options cover a mix of street-oriented radial series and more specialized selections within the correct Firebird fitments.
Brand should be treated as one part of the decision rather than the entire decision. Once the proper size and wheel diameter are confirmed, it makes sense to compare each brand’s tire series, sidewall style, rim-width compatibility, and general presentation so the final choice suits both the car’s setup and the way it will actually be used.
Restoration & Appearance
Which tire should I choose for a period-style 2001 Pontiac Firebird?
A period-style 2001 Pontiac Firebird tire choice starts with keeping the correct size for the exact sub-model and wheel package. Standard Formula and Trans Am models use 245/50R16, while Hi-Performance Package cars use 275/40R17, so preserving the original size relationship is usually the first step toward an authentic overall look.
After size is settled, sidewall treatment and tire series shape the visual result. Blackwall tires keep the appearance understated, while raised white letter or redline options can push the car toward a more pronounced enthusiast presentation; buyers chasing exact originality should still compare those appearance choices against marque-specific references for their particular Firebird.
How does tire construction affect the appearance of a restored 2001 Pontiac Firebird?
Tire construction is less of a visual dividing line here than it would be on an earlier collector car, because the 2001 Pontiac Firebird uses radial fitments throughout. The more noticeable appearance differences come from size, sidewall profile, and whether the tire uses blackwall, raised white letter, or redline styling.
That makes size accuracy especially important on a restoration-oriented Firebird. A tire with the wrong wheel diameter or a noticeably different overall profile can change the stance and wheel opening appearance, even before the car moves, so the best visual result comes from confirming the exact sub-model fitment and then choosing the sidewall treatment deliberately.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2001 Pontiac Firebird?
Yes, modifications can affect tire fitment on a 2001 Pontiac Firebird even when the tire size is correct for a stock sub-model. Aftermarket wheels, altered offsets, suspension changes, lowering, or body modifications can change the space available for the tire and influence how a 16-inch or 17-inch fitment sits in the car.
A Firebird that has been changed from stock should be checked more carefully before replacement tires are chosen. Measure the actual wheel diameter, confirm the wheel width, and inspect steering and fender clearance at full travel so the next tire matches the car as it exists now, not simply the original factory configuration.
What should I inspect before driving a 2001 Pontiac Firebird on new tires?
Before driving a 2001 Pontiac Firebird on new tires, inspect the wheels for damage, confirm the tire size matches the sub-model and wheel diameter, and check that the tires seat properly and hold pressure. It also makes sense to look over the suspension and steering components so worn parts do not interfere with how the new tires behave.
A short clearance check is worthwhile before regular road use. Turn the steering from lock to lock, look for any signs of rubbing, and recheck pressure after the first drive, since a Firebird with previous wheel changes or aging suspension parts may reveal issues only once the car is back on the road.
What should I check before a longer drive in a 2001 Pontiac Firebird?
Before a longer drive, confirm that the 2001 Pontiac Firebird’s tires are the correct size for the sub-model, properly inflated, and free from visible cracking, bulges, cuts, or irregular wear. On a low-use car, tread depth alone is not enough; age and storage condition matter just as much as the amount of remaining tread.
A longer trip also puts more emphasis on the rest of the wheel-and-tire system. Check for slow air loss, make sure lug hardware is secure, and give the suspension and alignment a quick review, since an otherwise attractive Firebird can still develop vibration, wandering, or clearance problems if the overall setup has been neglected.
