I have a 1991 firebird with the orginal wheels on it. I am pretty sure they are 15 x 8. I am getting ready to lower the car 1 inch all the way around. I want to know what is the wides tire I can put on it without rubbing.

I DO NOT want the tires to stick out of the fender wells.

 

if you have a V6, i believe the stock tires are 15x7, someone correct me if i'm wrong.

no, you're right--15x7

 

Thanks, I was afraid of that. Oh well, gives me an excuse to buy new wheels. I guess I will step up to a 16 x 8. I really want to put GTA wheels on it. I am in the Dallas, Texas area, and I am not sure where I could locate a nice used set. I want the black ones. If anyone has any info on this, let me know.

Again thanks.

 

I have and 89, the stock wheels are 15x8, and 265/50-15's fit nicely. They will rub at the steering wheel locks (parking). Nice fat tire. Mine is also lowered 1.5 inches.

 

sorry buddy, stock 15 inch wheels are 7 inches wide. 15x7.

Was there some kind of appearance option for the v6's? Maybe the first owner upgraded the car?
