Depending on where you live and the sort of winter conditions you experience, I would be more concerned about stickyness than rolling resistance. Unless, of course you put winter tires on anyway. My past, and not recent by any means, experience with Michelin was that I could not wear them out but I had no grip when it got cold.

(sorry, i don't have the model number/name of those Michelins handy right now, but they were a rebranded model specifically labeled for one of the major tire chain stores.) much to my surprise, those Pirellis have lasted almost 60K miles so far. WRT to rolling resistance; there was a sidebar in the AAA magazine recently that mentioned one of the subscription consumer organizations (Consumer Reports, IIRC) was the only group actually doing standardized rolling resistance testing. in my experience to date, tires that had lower rolling resistance typically also had poorer traction and/or ride performance. if that's changed for the better (and only fair testing would show that) and assuming that those tires are not suffering in any other area of performance, one has to ask oneself how much one is likely to save in fuel by using those tires to determine if any additional cost it worth it. personally, i'm most interested in a tires grip and reliability, with ride and availability of support following close behind. wear and rolling resistance fall far behind in the list of primary considerations. cheers! e Dillon, Meade M CIV SPAWARSYSCEN-ATLANTIC, 53310 wrote: > A few years ago when I was tire shopping, the lacking bit of information > was tire rolling resistance.
