Just hit 19,000 miles on my stock Dunlop front tire!!!(14 SGS), measured tire depth is 2/32. During my routine safety inspection I found a crack on sidewall 1/2 in long that wasn't there previously, so I will be replacing tire w/ same. Really surprised I got this many miles out of this tire.. most of my riding is desert/ mountains occasionally 2 up. And yes I check my tire pressure before every ride (36/40 psi) guess it paid off!!!
