I won't do 4-1 again in a easy wheeler. Trying to keep up on fire roads and open stuff sucks. I have a 3-1 case siting and waiting for the next build. I dont really notice noise but put a lot of sound deadening on the tunnel.
colin used to just pull in on 15" rims no tires. there is a set here you can use! I used to just air down my 33's and pull in then air back up.. PITA but easier than changing rims. doesn't sound like you have the room to have any rubber on there...
