alright, i got a hawk gt and it's factory tire size says 110/80/R17 and 150/70/R17 Rear. Since Pirelli is running the buy one tire get one free promotion, i'm thinking about picking up a set. But, the problem is they only have 110/70/R17 fronts and 150/60/R17 rear. Will this set up work or will there be handling problems? Would there be any other adverse affects?
