Customers who drive will inevitably encounter these problems, such as high-speed puncture, puncture in urban areas, flat tires in parking lots, and sudden tire problems during long-distance travel. Every time, they need to call an emergency trailer for rescue and drag the car to a repair shop for maintenance. It not only costs expensive trailer fees, but also wastes a lot of time, so a new industry, mobile service rescue was born. We designed and produced the mobile tire changer, wheel balancer and maintenance equipment to solve the problem of mobile car service. No matter you are in urban areas, highways or remote road sections, as long as there is a tire problem, you can drive a mobile vehicle equipped with a tire changer, a wheel balancer and tire service equipment to directly repair the tire, change the tire and do dynamic balance on the spot. It saves time and money.
