What's the difference between vacuum tires and ordinary tires? Can I use vacuum tires to make a small downhill? What should I do if the vacuum tire bursts? Do you want to change the tire directly? big

1. The thickness is different. Generally, the DH tire of 2.5 is 600-900g, and the vacuum tire 1200- 1400g. Moreover, the vacuum tire must be filled with self-rehydration liquid, which is definitely heavier than the ordinary outer tire+inner tube. So it is wrong to say that the vacuum system reduces the weight.

2. The tire lips are different. Because ordinary tires use inner tubes, the accuracy of tire lips is average, and it doesn't need to be very soft, and steel wire edges can also be used. The vacuum tire is specially designed for the vacuum ring. It fits perfectly and must be soft, so the vacuum tire must be a folding tire. But the folding tire is not necessarily a vacuum tire. The rings marked UST and TCS are all vacuum tires and vacuum rings, and it is not without them. UST is an international standard vacuum system, and TCS is a quasi-vacuum system created by WTB, which is basically universal. .

3. The quality of the tire is different, the ordinary one is ordinary rubber, and the better one has a puncture-proof Kelaf layer, which is bulletproof material. Vacuum tire must have Kevlar layer and fiber layer. Let's talk about the principle of vacuum self-rehydration. When the tire is punctured, it is self-rehydrated and sprayed at high speed, and then intertwined with the fiber layer to fill the hole. It is difficult to close the loophole by rehydration alone. Ordinary tires have no fiber, and the effect of self-rehydration is there, but it is not great. Vacuum tires also have holes. Generally speaking, the tire pressure should not exceed 40PSI. If it exceeds 40 psi, it will continue to leak slowly until the tire pressure is relatively low. Tire pressure of 60 is impossible to make up for this.

It is good to use vacuum for light downhill, but heavy or fr is ok, but it will increase the chance of falling, so most players in top competitions like to use ordinary inner tube system. But our strength is not worth mentioning at all. Vacuum is a good choice. Even if I use a vacuum, I can often jump 1- 1.5 meters on the flat ground.

If the vacuum tire bursts, let the self-filling liquid fill it up, and leave the rest alone. If the fracture is too big to be repaired by self-rehydration, it will be scrapped. If it cannot be repaired, it can be replaced directly.
