For what it's worth............... If you use these or are thinking about it, DO NOT put these on your bike or take them off. Not worth the savings. I thought I would save myself some money and put a set of these on instead of the usual Metzler Tourances, what a hugh and almost deadly mistake. At first they appeared to be wearing OK, good grip both on and off road but then I noticed the rear tire had 7, yes 7 seperate tears right down to the steel. Then I checked the front tire and it too had some seperating. They had some really good reviews but then again I don't think many vendors are putting the bad reviews on-line. Just my 2 cents..................... PLEASE be CAREFUL.
