I love the AT Xtreme as well, that is what I have on my Expy, 20K miles, and no obvious wear as of yet.
As far as Riff's tire advice, he does offer facts that back up his opinions, which is valuable, as compared to those saying, "this is what I have, and therefore is awesome!!" Thanks Riff for the advice, and I don't always follow his recommendations, but at least I know they are thought out.
That is what makes this site great, tons of experience, somewhere in the accumulative of centuries, and all have their merit. Thanks everyone!!!![]()
