Hey, this is yet another call to my always insightful if sometimes strange (talk about the pot calling the kettle black) cycling readers. I've been summer commuting on the same tires for almost three years, possibly more. I am crummy at keeping track of such things. They are Bontrager Race Lite Hardcase(s). I have been very pleased with them.
The sidewalls are in fine condition, but there are a number of decent cuts or cracks in the centre of them:
I know I am inviting the flat gods to rain bad fortune down upon me, but I haven't flatted once in all that time, which included a few longish (60-80 km) highway trips. So, should I continue to tempt fate or would you think there's a little life left in these still? I lean toward treating tires like I do cars... ride them until they fail completely. Trouble is, I don't want to experience that complete failure on a big ol' downhill stretch.
As always, thanks for letting me use you as sounding boards... I didn't want to leave this earth-shattering discussion in the hands of strangers!
Try to Stay Pumped,
