In the replacement of electric vehicle outer tire, we need to focus on the issue of tire wear resistance. Soft material tire can obtain larger traction force, but wear faster in daily use, while hard material tire damage slowly, but poor grip performance.

Therefore, tire manufacturers usually consider a number of factors when designing tires, so that the tire can achieve a balance point between grip performance and form mileage. In fact, from the comparison between vacuum tire and bladder tire, the overall performance of vacuum tire is better than that of bladder tire. Although its price is relatively high, vacuum tire should be preferred in consideration of safety.

The outer tire of vacuum electric vehicle has stronger wear resistance and is not easy to be punctured. Of course, its security is also better. Generally speaking, if the user can get rid of the vacuum, they will not be frustrated. However, the vacuum tire also has its own disadvantages, that is, the price is several times that of the gallbladder tire, and the maintenance price is higher than that of the gallbladder tire.
