Me too. My Work & Play came with them and we have close to 10K and they're fine. I always keep them in the dark when stored and they never get below 75-80 psi.
My concern is, even though its three axles, there's still much more weight than what my Westlakes carry now.
In comparing Fuzions against XLRs, I give this point to the Fuzions. Every Fuzion I've seen already have Sailuns and every XLR I've seen have Westlakes. Good tires but still not G rated.
