Hi Guys, I have a set of stock 85 5 spoke camaro wheels I'm putting on my 79Z. I looked in the tire sticky but still not sure here. What is the largest tire I can put in back? What would you guys recommend. I;m thinking 255 60 15 in back and 215 65 15 in front. Any info appreciated. I do have 1" lowering coils in front, the rest is stock.
