how about gen 3 15 or 16in wheels
i have 2 setx of 16's a set from a 92 Z and a set fron a GTA
and 1 set of 15's from a 92 RS

 

I have seen them on second gens.

 

I'd like to put the largest tires I can on my '78-'79 5 spoke Z28 steel wheels. I want to fill the rear wheel wells as much as I can without the tires sticking out past the upper wheel well lips. I think the most I can go on these wheels is a 255/60-15. A guy on another site has 275/60-15's on his '80 Camaro with the same wheels. They don't look to bad. A few guys said the 275/60-15's could flex to much on that size wheel. I don't know.
