I am putting on a 6 inch skyjacker lift on my 95 f250 powerstroke was wondering what tire I should run I was trying to decide between the 37x12.5x16 SSR or the 38x12.5x16.5 SX I do alot of highway driving nothing crazy but a good amount I know the SSR radial would be the choice for that, but I love the way the SX looks wondering if anybody out there has had either tire and how have they held up thanks for the help....
