Tire thread time

[Julian Solomensky]

I used the diablo stradas in stock size on the gpz with great results.  Lasted a good 10K or more too.  That was the only tire I replaced with an identical one too.

In the last week I changed tires on the c14 (at just shy of 9K miles).  The stock BT021's were garbage (both in terms of wear and performance).  I paid through the roof and went with the michelin pilot road 2 (also in stock size).  We'll see if I manage to get a few more miles.

FWIW, the 021's started handling poorly early as 3K, but still had lots of tread left.
