if using the tuffy liner for your motorized bicycle take the ends round the corners with a sharp set of scissors. the corners are sharp and they will wear a hole in your tube after time,
Tire liners are the easiest to use but it is premises of putting anything hard to penetrate between your tube and tire tread and all kinds of things can be used.sigh,the price i pay for such a wide wheel. maybe with fat bikes catching on,i can mod one of those tire liners if they exists?
Slime washes off easily with plain ol' water. Anyway, there are 2 things you can do for a tire liner in your case:ive been running slime in my fat rear OCC schwinn stingray 20 x 4 1/4 since 09', its been the only solution for such a rare tire. no kevlar or torn resistant tube available in this size and im worried about trying to stuff two tuffy's liners in the there side by side. maybe it would pinch cut the tube?
anyways, slime has taken the abuse from fishing hooks ive had to pull out,broken glass,etc. for me for along time.
well,some how my tube got a bigger hole in it than normal,and because the bigger the tire the more slime i used,it blew out all inside of that rim,oh man, it was terrible to clean all that crap up. I dont want to use slime again because of it,but now im nervous to ride long distances because of no tire protection at all.
