Working Principle TIRE GUARD:TIRE GUARD over in the tire will remain as a liquid is thick and will always participate in the corresponding round spinning wheel, for a period of about 1-2 years of usage, and capable of automatic patching dozen nail holes.TIRE GUARD is designed specifically for patching tires while on the go.There are three things required for filling TIRE GUARD:1. Rotation or spin the wheel.So the possibility is getting bigger and faster formula TIRE GUARD contact with nail holes due to the centrifugal and centripetal force of the liquid formula.2. Wind pressure in the tires.TIRE GUARD during use, it is advisable to replenish and maintain the air pressure to keep it high (at least equal to the pressure recommended by the manufacturer of tires each are listed in each tire). Due to the high pressure is getting stronger and faster while pushing formula TIRE GUARD plug and patch the nail holes area.The process of closing the hole in the tire place in quick time and very little wind is wasted in this process. In the condition of the vehicle is running, the hole will close completely in less than 3 seconds. So we will not realize when we punctured tire spikes / sharp objects on the road.
