I have a new wheel and tire package that I bought for a project but have changed direction. They are 5x4 3/4 bolt pattern 20X10 and 18X8 Foose Nitrous 5 with Nitto NT555 275/35/20 and 245/40/18. Not sure about the backspacing but they were set to go on a 1971 Firebird. I paid $2400 for the set. I am asking $2000. I live in southern Ohio and would prefer pickup but will ship at your expense.
