I realized today that the Conti Trail Attack on the rear of the bike has been there for almost a year. I put it on prior to a trip to Big Bend last Christmas. I've ridden lots of miles of gravel road with it, and many miles of street while suffering from that issue with the front wheel coming up on acceleration. Best guess, I've got between eight and ten thousand miles on this tire, and I think this is very, very strange. Prior to putting this tire on I wore out two Scorpions and a Dunlop Knobby on the back between February and December of 2011, so I know my riding style isn't conducive to tire longevity. Granted, I am now one year into a marriage, and that has kept me off the bike a little, but she has two bikes of her own (Monster 696 and a TW200), so I know that she hasn't been an effective deterrent, the way I hear many complain about. I'm thinking there may be something else going on here. Alien abduction perhaps? There's no way that this tire has survived this long with me riding 70/30 paved/gravel. I'm somewhat ashamed and abashed that I wasn't able to wear it out quicker. Nonetheless, I'm putting another one on there. They aren't the best thing on the dirt, but they aren't bad, as long as you are ready for the inevitable sliding around during braking or downshifting on gravel. Balancing the long life against me having to be a little bit better rider on dirt roads, I'll accept that challenge and see if I can get another year out of the next one. Heck, I've even put one on the front now and have been pretty impressed with it on the dirt roads. Anyone else having this disturbing issue with long rear tire live on their 9X0? Maybe we could form a support group?
