i have a 1987 gta and it has 15/8.5 convo pros on it what is the largest drag radial i fit on my car thanks alot

 

Whats your backspace? I have 275/60's on 15x8's with 5.5 backspace with minimal inner fender mods. It all depends on backspace if you don't want them to rub.

 

my wheels have 5 in backspaceing thanks alot

 

You should be fine with a 275/60 they are 28" tall and about 11" wide. Here is a pic of mine (nitto 555's) how they sit in my fender well.

 

hety thanks alot for the pics

 

a 295 will fit in there too, it'll just be taller
