Put new tires on recently.
Ended up deciding on Yokohama MTs. Kinda overkill I know. Price-wise they were pretty reasonable and there is a 30 day trial period so I figured I'd try them out. If I ended up hating them I'd opt for Toyo ATs which were a bit more expensive.
Went from 275/70R17s to 285/70R17s and it looks like I will need to do the cab mount chop. They rub in reverse.
Noise isn't terrible, not a whole lot louder than the KO2s were after they got a few miles on them. They also ride pretty smooth. Ride isn't any worse than the KO2s and I noticed they needed a lot less weight to balance.
So far it seems like the mileage has dropped, although its hard to tell in just a few tanks of gas. I also felt like the mileage dropped after I put the KO2s on and after I went back and looked at my mileage spreadsheet and long term it was almost exactly the same.
