The rear tire has been holding air fine, but the tread was getting rather shabby. I'm a cheapskate, so I've been trying to milk as many miles out of it as possible. The last ride was the last straw. The tire was just a little too slip-slidey, so today I slapped on a replacement. For some odd reason, I'm always compelled to examine every part, even those that are destined to the trash can. It's not rare to find something protruding from the back side of a tire -- nail, thorn, or piece of glass. For that reason, I never "feel" the inside of the tire. I've been poked too many times. But today's visual examination revealed more than a dozen cactus thorns poking through the carcass. I guess all that money I've been spending on Stan's is really worth it. I thought that maybe you guys would like the pictures.
