Run a tire that has a lower design pressure.Ī fatter tire has a lower design pressure. I am not suggesting you run A tire at a lower pressure. I know people say higher pressure is better for puncture resistance but I disagree. This is where you get the best bang per weightīefore you go out and buy THE most puncture resistant tire consider it comes at a cost. Some puncture resistant tires tires even have a spacing foam. It is a harsher ride and not as much grip. A glass flat rarely happens in two seconds or two minutes. From inspection that glass had been in the flat tires a while. I have pulled glass out tires at least 20 times. Tube does not resist puncture, cut, or abrasion. If you leave the glass on the belt long enough it will work through. If the tire is thicker than the belt then the glass will not make it to the belt.īut these fibers cannot stop abrasion. This takes many revolutions.įirst the glass has to make it to the belt. There is minimum or threshold force per area for the glass (or any sharp object) to penetrate the surface. The glass penetrates the rubber surface. A sliver of glass is rarely standing upright. At least those are easier see - steer clear.Ī long narrow sliver of glass does not have the structural integrity to puncture a tire in one pass - glass will fracture. But like the base of coke bottle with some 1/4 points sticking up. Not often you will get sliced open by a big chunk as the sharp edge has to be up and since glass is brittle you often break it.
