Does anyone know how large a tire I can squeeze under a 68 short stepside that has been lowered 5 inches in the rear? I have 15 X 8 rims that I'm mounting them on. Would like as wide a tire as I can fit .

I would like to know aswell. Although I do not see buying wheels anytime in my future.

I've always run 275/60/15's on 8 inch wheels in the rear. Assuming 4.25 to 5 inch backspace on the wheel, you'll have no rubbing. That's about as wide of a size commonly available in most brands.

I've heard of guys putting on 305's but I'm not sure eactly how much of a drop they did.
