Three T on City Motorcycle tire
US Department of Transportation regulations, car city motorcycle tires must have the city motorcycle tire wear (TREAD WEAR), temperature (TEMPERATURE), traction (TRACTION) and other signs. Referred to as the "three T" indicators.
    "Three T" indicators are tested and provided by international authorities. "Wear indicators" to measure the city motorcycle tire tread wear resistance and service life, its level in a specific number. "Temperature" to measure the level of City Motorcycle tire driving up and down, in fact, and high-speed performance of City Motorcycle tire, it is A, B, C distinction. A grade is excellent, B grade is good, C level for the general. "Traction" to measure the city motorcycle tire and ground adhesion performance, but also to A, B, C three distinction. A grade is excellent, B grade is good, C level for the general.
    The US government requires that the city motorcycle tires exported to the United States must have a "three t" indicator. At present, China's Shanghai back to the city motorcycle tire factory production of City Motorcycle tire above the "three T" indicators. For example, the Santana 2000 sedan uses the 195 / 60R14 city motorcycle tires, its "TREAD WEAR" is 450, "TRACTION" is A, "TEMPERATURE" is A. "TREAD WEAR" on the 185 / 70R13 city motorcycle tires is 180, "TRACTION" is B, "TEMPERATURE" is B.
    So, how much of the wear and the number of miles is calculated? Figure 5-10 shows the test method for the wear of urban motorcycles.
    Through the test, to wear 100 as the base, wear 100 can travel 48000km, wear 200 is 96000km. So, the above-mentioned Shanghai back to the factory production of 195 / 60R14 wear 450, then it should be able to travel 48000 x 4.5 = 216000km; 3185 / 70R13 wear is 180, then it should be able to travel 48000 x1.8 = 86400km.
    Of course, the test site and the road is not the same, and the situation of each area of the road is not the same, each driver driving habits are not the same, so the actual use can not ask the city motorcycle tires must travel to the presumed kilometers But the number of kilometers can be deduced from the wear figure.
    As for the temperature and traction, should try to choose "A" level is better, especially the temperature, usually the temperature known as the city motorcycle tires "first killer", therefore, should be carefully treated. Of course, some city motorcycle tires "three T" indicators are not necessarily satisfactory, but you can according to their actual needs targeted to choose.
    According to the United States UTQG logo, urban motorcycle tire wear index between 160-300 city motorcycle tires, for the summer standard; 160 to 200 between the city motorcycle tires for the summer high-performance type; and 300 ~ 540 Of the city motorcycle tires for the weather standard. As shown in Figure 5-11.
