not to take anything away from you. but 15x7 all around is way to thin for a rear wheel not to menion a 225 tire at the rear also way to thin for a rear tire.
again not to take anything away from you but that size tire in the back will just make it look like Grandma's car no disrespect...
15x8 in the rear will fit just fine. and if your worried about tire size 245 will fit guaranteed but id go 255.. ;) :cheers:
