I'm officially in SoCal now and getting settled in. Its been a while since I posted on the thread but wanted to chime in.
I'm running the BFG KM2 (MT) and love them for all purposes. Road noise is not bad because all I hear is my awning and roof-rack! hahahaha!
Regardless, they are not that bad. I had a great deal of experience with BFG AT and Nitto AT in the snow and was not impressed so I can only assume my MT will not be too much worse if anything.
Anyway, I do not see a lot of mud here just yet but have about 500 or so miles on them in the straight desert, rocky environments around the Chocolate Mountains and dunes in Glamis and they are fantastic. I can't say how happy I have to have made the 17" wheel transition and be able to air down to optimum off-road tire pressures. The traction is fabulous, and a 10ply tire is a premium for our weight of a vehicle even though they are heavy.
On the road, with all the crap hanging off Victory, the last two tanks have given me an average MPG of 14.7mpg which is pretty darn good IMO. Mostly highway and low-speed driving but that's about the extent of her life these days on the way to the trails.
Off-road, MPG sucks as most of you know; super heavy to Yuma a few months ago I was getting about 10mpg over the mountains and about 12mpg flat on the freeway at 65 or so. On the trails with the low-range box engaged and many times not, I average about 8mpg, but the traction is "knock your socks off" amazing.
My next pick is going to be for extended range tank to stuff under the spare well.
Happy Rovering my friends!
