Hi guys, my wife has a S reg Focus 3 door Zetec with 215-45-17 tyres on 4 stud, multi spoke RS style wheels. These are the wheels that were on the car when she recently bought it. We find that these wheels may well be too big for the model. Does anyone know if a 17" wheel can be safely fitted to this model & if so what is the widest tyre that could be fitted. If not that's the biggest & widest combo? Any help you can give would be most welcome.
