took the bike in as i reported in may. was told i had a couple thousand miles left on the rear tire. when i got home from Canada, i went and bought a rear tire just figuring i was getting close. upon checking this morning, i find i have 4/32 on the rear at the wear bar and only 2/32 on the front. 11k isn't much mileage from a front tire. i moved the bike around to be sure i wasn't on a bad spot but the wear is uniform. anybody getting much better from these?
