I have a '05 Rubi LJ, and the stock MTR's with a E load rating, never made any sense to me. I've been shopping for replacements, and so far, C and D rated choices re slim at best.
Retaining the stock Moab with the 16'' diameter, is paramount to me. I really like the look. But finding a aggressive tread that isn't E rated has been tough.
Cooper tires has a couple of options that I am considering. I'll be swapping up to 255/85/16, which is a 33'' tall version of the stock 245/75/16.
Keeping the tread width to a minimum will reduce weight, and I prefer the look anyway.
