The O.P. stated he was fitting them on a LJ. That is what I have. Original tires were GY MTR's, E rated, and the thing rode like crap! E rated is fine for 3/4, and 1 ton trucks. But, on something as light as a Wrangler, there are better options. I switched to Cooper Discoverer ST's, in 255/85/16D. I could not be happier, as the ride is so much improved, over factory, without changing anything else.
I'm not even sure if Cooper still makes my tire or not! Might be worth a look.
Edit, Just looked at Coopers site, and apparently, they are no longer offered.
As oringinally stated, I would avoid E rating on a LJ.
