Cooper Cobra RWL turned in 245-60/15 on Vision 8" Nitro out Back.
The wheels are knock offs of Welds from Summit. They only come with 4" back space. If the wheels came with 5" backspace I could get a 275 on there easy.
But such is the limitations of wanting to keep the car stock and buying readily available inexpensive wheels. I have a few guys to tell me to run a small spacer and go wider. I don't mind the 245s....
