whats the largest size tire i can get to fit correctly on my 87 trans am? i have the GTA cross-lace rims and i believe i currently have 225/50/16's on there right now, atleast i think i do. i was on tire rack and it had different sizes (i failed inspection and now i need new tires) and i would really like to get some that i like. thanks. -brian

Largest street tire that will fit, without zero modification to the wheels or body, on the 16" x 8" wheels, is 255 up front & the BFG 295/60 out back.

That'll get your car going & back on the road quickly.

When your wallet will allow....Go to a 17" rim & 275s will fit up front. Start cutting, welding & the sky is the limit on the rear, only limited by the work your willing to do.

You can do what stephen says...

Most people tend to go with 245/50/16's all the way around. You can do 255/50/16's too.
