Hey all, my friend needs a new tire since he hit a pot hole and blew the sidewall out. I have an extra used tire but it is slightly different size. It will be going on the rear of the vehicle and the car is FWD front wheel drive. (Hyundai Elantra) His tire size = 195/65-15. The spare I have laying around is 195/55-15. He wants to use it for a temp solution until winter but was wondering if this is safe or not?
