He is already running some pretty big tires on the dodge. I used to run 35*14.5's on my toyota and it was alot ofrubber to keep spinning. I think some wider tires wouldlook better, but some states regulate that. I had a friend in VA get his tags taken off because he was running 19 inch wide tires(I think it was colorado that is big into not having wide tires but not sure). Also if he has alot of play in his suspention(For rock climbing and the like), then he wouldn't want a bigger tire(Although it looks like that truck is just for show). I think that is alota show and no go. After all when it comes to trucks, chrome won't get you home.
