Hello all, get my Ford Focus bj 2012 next week. I wanted to buy bigger tyres than the 16 inches that are on it, because probably 18 inches the size is, I would have to take the 235/40 R18 91H according to the letter. But because I am 235 too wide I wanted to ask if I can take Z.b 215 without having to register it. MfG and already thanks in advance
