1. DO NOT get Mud Fappers, I hate these loud, overplayed, gay as fuck, cen-cal, bullshit tires. they suck asshole. They have terrible traction in rain/ice. And they're god-awfully loud.
2. DO NOT get Terra Fappers, brother had those, they wear fast, still pretty loud, and not much tread
3. plz, for the love of humanity, don't turn that beautiful truck into an eskimo version of cen-cal gayness
best bet for tires is toyo open country m/t, yes everyone has them but it's for a reason, they're badass! quiet, good tread pattern, and don't kill your mpg. same brother now has 35" open country m/t's and gets 12mpg all day and he was getting 8-9 mpg with the terra's
