20. HIGH-SPEED TIRE TIRE FLANGE BEVEL ANGEL If the tire flange radius is smaller than the wheel rim radius, the tire and wheel can Tire flange bevel angle is larger than rim bevel angle Tire Shape be locked tightly. Take the advantage of tire bead bevel angle to enlarge tire bead so that the tire and rim can combine with each other precisely. Consequently, it Rim Shape can prevent air leaks and tire will not fall off the rim when tire break or low pressure occurs. Locked METHOD TO IDENTIFY A HIGH- SPEED TIRE For distinguishing a high-speed tire from a tube-tire, the word "TUBELESS" is stamped on the side wall of the high- speed tire. A tire without this word cannot be used as a high-speed tire. TUBELESS RIM USED FOR HIGH-SPEED TIRE For the purpose of preventing tire from falling off the wheel rim while driving, there are special requirements on the size, shape and pressure density of rim used for high-speed tire. It is necessary to use special rims. Refer to the Figure shown for distinction. Air leaks occur easily when the wheel rim is deformed. Avoid driving on rugged Rim Used for High-speed Tire road and crashing against stones. When replacing the high-speed tire, also replace the valve as a set. Rim Valve · When replacing the high-speed tire, use a tire of the same specification. Mark of TUBELESS 20-2
