I was stubborn on leaving a set of BFG Krawler TA KOs 35 x13.5 x15 on my 68EB, truck has new steering box, WH clydesdale Tie rods etc, I thought it was good and stiff n tight. Switched out to BFG AllTerrain TA KO same 35 x 12.50 x15. Dont do mud do sand and pavement, Krawler no good on sand ATs are smooth and QUIET---- should have changed a year ago, man its a new truck---fought my own common sense for $$$s.
