We’re huge fans of WTB products and are super stoked on the new TCS tires. For those who want to know what all the hubbub is about, Decline Magazine has done an excellent review. Though they state the TCS tires are the same weight as the race versions, our own independent testing has shown that the TCS tires are in fact heavier (considerably in some cases) than their Race counterparts. However, they are every bit worth the cost – and weight. Actual weights can be found on our website. Look for our own review soon. We’ve been thrashing around a set of Weirwolf 2.3 AM TCS’s and are so far in love with them. In the mean time, check out this article, as it does a great job of explaining the technology behind the tire.
