i need to fit the fattest slicks i can on my 90 mustang. currently i have Weld 15x8 draglites with 5 1/2" backspacing with 26x9x15 slicks, the wheel wells are stock. can anyone share what theyve managed to stuff into their wheel wells? along with rim sizes, backspacing and tire sizes? im going to buy new rims and tires.
