A 215/40 on an 18x9.5 is a stretched tire — that's the bill tuck hands you before the car even sits down. Tuck pays in tires, poke pays in fenders and hubs, flush pays in measuring twice. One millimeter of offset is one millimeter at the fender, and half an inch of rim width is about five millimeters of section width. Send this to the friend about to buy wheels he hasn't measured for. #ThreePieceUS #cars #wheels #stance #wheelfitment #stretchedtires #fenderroll #offset #carculture #flushfitment
