Yeah, I've seen those too..I think Michelins?
I bought General Ultimax HPs, for numerous reasons, but one being that they had a very low rev/mile rating compared to other tires. I don't know if they are "officially" LRR, however. One thing I did notice, though, is that a lot of these fuel saver tires are not very good at doing anything else. Mine at least had good wet and snow ratings!
The width definately makes some difference. I think the lowest .cd for the w124 was achieved with like..185/15s or something crazy like that. I realize that isn't much different than 195s, but when you start getting into wide-rimmed 265 and whatnot, that must mess with the frontal area a bit.
