Michelin says its Power Pure, on the market since January, is the lightest sport premium tire ever made. Click here to download a PDF of a detailed press release Michelin recently sent out on the tire.
Michelin claims that the Power Pure weighs 2 lbs. less than competing tires in the same category and is the lightest two-compound tire ever approved for road use. The front and rear tires come in two and four different sizes, respectively, to fit a broad range of sportbikes.
In making the weight claim, the company says it compared the average weight of a set of Power Pure tires in sizes 120/70ZR17 and 190/50ZR17 with the average weights of the same-sized sets of the Bridgestone BT-016, Dunlop Sportmax Qualifier II, Metzeler Sportec M3 and Pirelli Diablo Rosso.
The company notes that reducing the weight of a pair of tires by 2 lbs. has the same impact on performance as reducing the weight of the wheels by 6 lbs. or the brake discs by 8 lbs. (The inertia of a mounted tire/wheel assembly equals mass times radius squared.)
Because the Pure Power weighs less, it “provides unmatched handling for greater responsiveness and superior riding pleasure," according to Michelin.
Specifically for the Pure Power, the company developed a second generation of its Two-Compound Technology (2CT). Engineers extended the soft layer of rubber on the tire’s shoulders to provide better traction when the bike begins to lean. The thickness of the tire’s tread leads to long tread life, Michelin says.
Less unsprung weight for the same amount of rubber, Michelin claims, is the result of its Light Tire Technology (LTT), which is an illustration of its strategy of never sacrificing one performance feature for another. This means improving performance in several different areas simultaneously, the company says.
