Others like motorcycle tyres, commercial tyres, and light truck tyres (including 4&#215;4 tyres such All-Terrain tyres, Mud-Terrain tyres) are exempted. As a result, tyres that do not print or had blur ratings will be recalled.<\/p>\n\n\n\n<p>On the flipside, UTQG is not compulsory on other markets like Europe and Asia. Hence, some tyres, as long as it&#8217;s not selling in the U.S. market, may not have UTQG rating on it. It&#8217;s also possible that the batch of tyres sold in the U.S. market is different from the batch sold in other areas, therefore, it does not have UTQG rating on it even if the same tyre model is sold in the U.S. and your area.<\/p>\n\n\n\n<figure class=\"wp-block-image size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"378\" height=\"389\" src=\"https:\/\/tyrehood.com\/articles\/wp-content\/uploads\/2026\/04\/No-UTQG-on-050.jpg\" alt=\"\" class=\"wp-image-1960\" srcset=\"https:\/\/tyrehood.com\/articles\/wp-content\/uploads\/2026\/04\/No-UTQG-on-050.jpg 378w, https:\/\/tyrehood.com\/articles\/wp-content\/uploads\/2026\/04\/No-UTQG-on-050-292x300.jpg 292w\" sizes=\"auto, (max-width: 378px) 100vw, 378px\" \/><figcaption class=\"wp-element-caption\">no UTQG on Dunlop Sport Maxx 050<\/figcaption><\/figure>\n\n\n\n<p>The system has 3 categories: Treadwear, Temperature, and Traction.

A kind of chemical reaction. And a small amount of heat can facilitate this chemical reaction. Nevertheless, too much of the heat will cause the bond to break, result in tyre traction failure.<\/p>\n\n\n\n<p>To simplify, imagine you get ice cubes from the fridge and you want to melt the ice quickly. You decide to use fire to melt the ice. You want to melt it real quick and make the fire bigger (increase temperature). The ice melt but instead of turning into water, it goes into vapor.<\/p>\n\n\n\n<p>Temperature rating is VERY important to long haul drivers. Higher speed accumulates more heat and heat can built up in long distance. As a result, temperature rating &#8220;A&#8221; is preferred if you are driving over the speed of 150km\/h<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Limitation<\/h2>\n\n\n\n<p>Almost all non-US consumers may mistake the use of UTQG to cross reference with all different brands and models.<\/p>\n\n\n\n<p>The treadwear result is self-tested by tyre manufacturers. Although the testing is done through the standard given by the U.S. department (just like EU tyre label), there is still possible variation in different testing methods. <\/p>\n\n\n\n<p>As such, Falken FK520L with treadwear 300 does not imply it cannot last longer than Kumho HS52 with treadwear 380. <\/p>\n\n\n\n<p>Nonetheless, UTQG is a VERY good indication to compare the same brand and models.<\/p>\n\n\n\n<p>If Falken FK520L compares with its own brand e.g. ZE310 R with treadwear 320, it indeed implies ZE310 R can last longer than FK520L.
