Is the treadwear rating the moulded number following the size and ending in a V? If so the Dunlop Direzza is 85 and is the same for S1, M1, M2 and H1 which seems a little at odds with the actual wear rate I have experienced.

And Ray, I have such a pile of used 205/50 x15 Direzzas that I had to climb up to see the numbers so curry remained undisturbed!
