I've just put on a Michelin T63 on the front of my superenduro. The T63 rear I do not yet have, because my current tkc80 is still good.
The T63 rear has exactly the same thread pattern as a Michelin Desert, but has way better grip in colder climates and on wet roads, this has something to do with the softer compound. The T63 front is not the same pattern as the front Desert, and seems less agressive and therefore is more suitable to dual sporting than real offroading. But for the trails I do, this tire is great! It's somewhat like a metzeler Karoo 2 "T".
Some inmates here ride with a combo T63/Desert.
