thanks for the kind responses!
how is a 20 inch wheel gonna do on unpaved roads? I use the truck off paved roads considerably. Was thinking of getting a fairly agressive at tire. I currently have bridgstones dueler. Nice quite tire on paved roads but don't perform nearly as well off the roads.
I think the wheels are 6.5 inches wide and I was thinking about widining out to an 8. Am i gonna have any issues rubbing or bottoming out on the stock suspension?
Also, I believe i am still on stock suspension (shocks, struts, etc), it has always felt good. Just out of curiousity, what's the life span on the suspension of these cars? Any other serious services or things I should investigate with an 90k gmc duramax, tire suggestions?
