The “rim width range” on the Pilot sport 4s street tire in 245/40/18 for example is 8” to 9.5” wide, so you’d be using a wheel that’s the widest for that tire recommended. It will work though! It may have a stretched on appearance instead of a more vertical sidewall.Appreciate your input ... Would a 245 40 18 fit the 45 offset 9.5 wheels ? I'm looking to get tires to put on my current rims until I get my titans in.
