Hello guys, I have a little problem again. And that is: There are several roads in the village, which have no good condition and also cobblestone pavers. If I drive on this road then poltert it just around the front as if one always kicks with the shoe against the tire. Then also comes the problem, that both front wheels have run off half-sided, whether the tires are probably only 1.5 months old. What can it be about? Cross handlebars I exclude, which were in August 2010 Changed (both)
