Michelin XZX were the Golden Grail on My +4-4STR. Until I could not get them in the U.S. Now I use a Chinese tire called "KUHMO" which IMO are ten times better.
However I was using YOKAHAMA on the +8 Bits. Now switched to Michelin Premier A/S (not expensive). I like the Michelin Prem. a lot better.
