I just bought a set of used wheels and tires for the car. The new size is 18x8 +35 offset. My stock back tires are bald and definetly not safe. My question is can i run my new 18x8 with tires on the back for a short period, along with my stock 17x8 in the front. Only reason im doing this is because the profile of the new tires is a bit to much and i know i will rub the front splash guard when i turn. This was a rookie mistake because i never bothered to look at the tire size.
