Is it fitted?? Mine have 225/45/18 (stock size i think) , I want little bit more ground clearance planning to 235/50/18 hope it will not rub or anything.
Mine are 235/45R18 on standard STi rims, it gives me an extra 4mm sidewall. That does cut down the clearance to the panels at the rear of the wheels. I cannot have mud flaps as they now rub due to this extra sidewall height, but other than that there is enough clearance all round. If you were to try 235s with a 50 profile I think you will have rubbing at the front whenever you turn the wheel, not on the guards but behind the front wheel where the mudflaps would be fitted as there is very little clearance there even with 45 profile when turning. I think you'd struggle even to fit a 50 profile of that width on the car let alone steer it
Did you end up doing this? If so, any rubbing?
