just picked up 4 wheel and tires (tires no good) at a local swap meet. the dude said they where off a 89 vette. the front ones are a standard vett size P275/40ZR17 the back 2 is what im worried about they are a bit wider. the tires on them r P315/35ZR17 so im guessing the front wheels are 9.5in wide and the rears are 10.5in wide. will these even fit. and if so what size spacers and lug studs will i need. any input would be helpful. thanks
