hello, changing my stock tires out for Nitto rt 555r2 tires. Also getting the weld wheel setup 18" x 10.5 rears and 18" x 8 fronts. The guy I'm getting the tires from is recommending I go 305 45/18 in the rear and 225 60/18 in the front. Does this sound like correct sizing? To me the front size sounds off but I don't know much about wheels and tires and the dealer I'm ordering from is just local so he's also learning as we go. This is going on an 820ish rwhp street car. If this sizing is off can someone please point me in the right direction.
Thank you
Thank you
