Pontiac Firebird Trans Am tire size
Original tire sizes for the Pontiac Firebird Trans Am, model years 1970 through 2002. Trim levels and wheel packages change the size within the same year, so confirm on the door-jamb sticker before ordering.

Which brand should you pick?
Pontiac does not stamp its own approval code on tires the way Porsche or BMW do. Any tire in the right size that meets or exceeds the load index and speed rating on your door placard is a legitimate replacement, so pick on wet braking, tread life and price. Our picks for each size are on the size pages below.
The drawing carries the sizes we list for this car, so you know what you are looking for. The placard on the car is still the final word, and it is the only place that gives the cold pressures: the number molded into the sidewall is the maximum the tire can hold, not what your car wants.
