Hey I'm back from installing my Shinko rear tire! Glad its on no more procrastinating for me! I got another week 200+ miles out of it, and i must say these tires are very impressive 7500 miles on the rear and even when you look at the guts of em! The 009 still has a good bit of rubber 2/32's left after it was smooth! Can't say that for other tires close to this $ range! For the low air pressure track rider! the 009 which isn't made for the track, but if, their track tires come off the bead as easy as this one there could be a problem! Bead broke easier than any other I've changed! I cut thru the baldest spot with a razor knife, (check out how much was left) cut to the bead, side cutter the steel! slip new one on with armoral! 45 min job start to finish now I've been thru it 7 times.
