half a year already I go on the second set of such rubber riding 50x50 gravel track in winter and summer. On gravel, according to the principle "more speed less holes", but it happens on the highway up to 140 km. The first set went up to 110 tons. this was a nordmanRS it's horror in all respects, bumps on three wheels came out at 30t. Km, and handling is generally like on skates in winter and summer.
