Ok, I'll correct myself. The Bridgestone B381 listed above as the absolute best, still has a traction rating of A. It seems that traction ratings and rolling resistance aren't as correlated as I thought. I do notice that the low RR tires do seem to have a lower treadwear rating (ie they won't last nearly as long).
Haha, i was just getting to your question when you answered it... I may or may not add a tread wear rating to all of this, we'll see. Is the tread wear rating you're looking at the "UTQG tread grade"?

This is what I can tell. Higher or lower number is better?

Thanks,
