ok this is gonna sound stupid..but what exactly is a fender roll..sounds like it might f#*k up my car..again i apologize...i'm new to this..my wife always had the nice car and i drove the pos..well shes gone and i finally got myself something coolDoh, might need a fender roll then...
so then no 225 on our 18x7 stock rim ... right?When I said that 225 will give the best performance, it is because it is designed to go on a 7.5"-9" wheel. A 235 is designed for an 8"-10" wheel. When putting a 235 on an 8" wheel, there will be more sidewall give and roll than if you run a 225. For straight drag racing, a 235 will give you more contact patch, but for everyday driving, go with a 225.
(Thank you Toyo Guy for a lot of this info that I spewed back out)
