I am always a little leery with off-brand tires. They do seem to have pretty good reviews; but I did see a review where the owner had to air down to 28lbs to get a flat contact with the ground. If you have to be at 28lbs; your gas mileage will suffer greatly. In my Wrangler JK, the difference between 28 lbs and 32 lbs was about 2 MPG; that was after already losing about 1 MPG with the bigger tires.
Also, after running my Wrangler for four years with 10 ply Terra Grapplers, I won't make the same mistake with my RAM. The 10 plys are nice off road when aired down to 20 lbs; but they hit hard on the highway when inflated (the smallest bump feels like a giant pot hole).
