I'm going to be upgrading to 35" tires and was wondering what size rim I should go with. 18" or 20"?
I think tire size is a bigger variable than rim diameter when it comes to MPG. A 20" rim mounted with a 31" tire would give you better gas mileage than a 15" rim mounted with a 44" tire.Does switching to 20" make a big difference in Mpg I am at the same problem. I found a set i love but not sure if i should just stick with 18' ?
