did a quick search, nothing came up.
anyways. about 100km ago got new tires (bt002, old ones were bt014 or 020, cant remember). on the way to the shop, i got tossed around by some crosswinds, but everything else was fine. on the way back, and then on the way to work next day my front would slightly wobble (maybe an inch or two back and forth) and I would feel the rear slipping away. that wasnt an issue on the old tires, even in the rain, as i was going to the shop, and i was already on the wear strip with about 100 miles (shop guy said that) left on them.
how long does it take for that black crap to come off? or what i described is not tire related?
