Here is a post from the original site way back in 05.
I got 19,000 miles on my first one and have over 37,000 miles on my bike now so that is about 18,000 on the current tire and it still looks good. Front looks even better so not thinking I will change them till the end of the year. http://www.hotrodbiker.com/forums/showthread.php?t=1709

My front tire lasted 13K and the rear tire lasted 15k It would have lasted longed but desided to burn it down a little means had a good deal on new tires.
