For a long search for a tire suitable for meadows, fields and bitumen roads in all weathers, downhill and uphill for my 20-inch electric bike I am now landed at the Jumpin Jack tires. It's for my application for a long time "the tire +++"! Rolling resistance is reduced as compared to my previous tires noticeably. In wet meadow or mat road I have first a safe driving experience. A fine driving noise produced during fast driving on a slippery surface. That to me is a pleasant "stereo sound". In the future, I'll just have to buy me these tires.
