Several years ago Mr. Tuffy tire liners were introduced, and we'll confess that we were, at first, unimpressed in looking at them, because they are an extruded urethane plastic strip between 1 and 2mm thick with tapered edges that is put in the tire, between the tube and the interior tire casing. The idea of using pliant plastic that's harder than rubber seemed just too simple. We also thought it was a pricey item, considering its raw material cost. After we had sold a few sets of Mr. Tuffy, customers started coming back and telling us how well they worked. In one case a woman witnessed her son, while on a ride, rolling over upturned barbed wire without puncturing the inner tube. Her amazement caught us like a virus, and we now recommend them whole heartedly. As we mentioned Mr. Tuffy liners are extruded plastic whose thickness varies with the type of tire and its width, that it will be used in.
