I've got 22. 5K on my LTX A/S on my '03 DR2500 4x2. Looks like they will go "at least" 100k miles... . <sigh>... . I wish they'd wear out MUCH sooner as I have never found a poorer tire for winter conditions. They are nice on paved, dry roads though. I'd like to find a Goodyear A/S tire to replace 'em, but as of yet Goodyear doesn't make anything in the size/load range that my DR needs.
