Hi, now i have a clearer understanding of the numbers on tires including the ET or offset. here is the problem i bought AMG replicas for both front and back 8.5x18 ET44 i i placed 224/40R18 tires on them now the problem is that the front tires wont spin since the front tires seem like they are too deep in. what do i do? help me please. thank you! are spacers advisable? i computed using the stock offset of 37 and it said that i had to move the wheel by 12mm.
