well I had an interesting weekend, got my car tech'd Friday evening and discovered I had an ~ 1/16" circumferential groove in one of my Hoosiers- just deep enough a small amount of cord was showing in places, so my Hoosiers were nixed for the two day race I believe that the groove was cut by the rear tire well (under mucho compression no doubt) last season, it was so small I never noticed it. the tires aren't in great shape, but the tread grooves were still visible so plenty of tread
the guy even commented had the tire been mounted to the inside he never would have even noticed it
sooooo- that put my on the oe Dunlops, something I wasn't looking forward to
after being on Hoosiers, going back to street tires (and not overly good ones at that) was a major step backward and opened a whole new learning curve
the second day my run group ran entirely in the rain (heavy rain) so I wasn't complaining on Sunday!
anyways I got lucky and came away w/ a little hardware
