I'm running Mastercraft Couser (MT) in the 245/75/16 E-rated. They are rated for up to 80psi. I've ran them at 75psi for the last 1-1/2 years and they are super. The high tire pressure helps gas mileage and turning in parking lots. Less road noise than the stock Mich 4x4, which is hard to believe given the open block tread.

I bought them in the heart of strip-mining country (logan, WV) at the tire store on old route 10, 500 yards north of Logan (between Logan and aracoma). They are the tire of choice for the mining company 4*4 trucks, relatively cheap cost, high quality, in stock, very well balanced, and rugged as heck (E-rated). The oversize has not been a trouble. I think the lower rolling resistance helped offset the lost torque. Lifts vehicle about an inch, given the higher air pressure. I think the total was under $500 installed with tax for all 4 -- 18 months ago !!! The guys in the shop ALL 4 wheel, ATV, offroad, and they respect range rovers for what they are. Since they work on 1+ ton mining vehicles they know more about the heavy duty systems on a range rover than people in the big city. My Hat's Off to them.

They go anywhere but up 50% grade sheets of ice on the shady side of the mountain. I needed to add chains for that one. RR with these TARs in west virginia offroad is more than heaven, it is the baseline for getting around in many parts. Add a winch if you have a shaky stomach. Forget about body sheet metal.
