wear is a concern for me... I drive twisty country roads daily, it's 30 mile round trip to work each day, and I ate steer tires like crazy on my K-30 I've been drivin for the past few years, but I also drive like a bat outta he77, hard in corners, etc... maybe if I just slow down a little, I'll save tires!
What about over size on a dually? I need to be able to reliably work the truck, but how do bigger tires affect a dually, if you need to use spacers to go bigger?
