I am running the Nittos in 35X12.5X17. I'm on Mid-Perch and have no rubbing issues. So far put over 3,000 miles on them and no complaints. They are a little noisier than stock BFG, but not excessively noisy. They do well in snow and wet roads. They are heavy, so they are a bastard to balance. you will see a drop in MPG with them.
But I love them, they make the truck look so much more badass.
My favorite part about the Nittos.
