End of life report (the tires that is):
95% solo riding, 90% highway commuting, 170 lbs. body weight. my preferred pressures are 38/39 front, 40/41 rear.
Replaced the rear at about 13,500 miles, right at the wear bars. Cut the tire and measured the rubber left in the center to the steel cords; about .07 in. so probably could have got another thousand or so out of it to the cords. Replaced with BT030GT.
Front still going strong; light cupping but still feels good, probably still another 3K left in it. That should be about late July and just in time for the new 030GT to go on for my week of tearing up the roads in the White mountains using my N. Conway timeshare as 'base camp'.
Overall a fine tire which I would have run again if not for the 030 superseding it.
