Thanks to all who encouraged me to KEEP TRYING to find the
Michelin MXT.  The local Costo store personnel were NOT helpful but I
found a local tire chain store that had some (expensive!).

They make a difference, much better ride.  I especially notice less
"wind-wander" when the trades are gusty (like today).

The tire (once again):

        Michelin MXT
        Load range "C"
        Reinforced side "R"
        Michelin part number #73568
