Michelin Power Pure Tires Review

I purchased the Michelin Power Pure tires on a recommendation from a guy who works at Cycle Gear. He said it would be the tires he would get the next time he needs to replace his tires. After looking into how Michelin designed their Power Pure tires I am very excited to try them out!

The Power Pure tires are sporting the latest generation MICHELIN 2CT dual compound technology. Ok, fine. But aren’t all major manufactures releasing dual compound tires now? And I’ve heard that some just don’t “feel” right.

But its main new feature is MICHELIN LTT (Light Tire Technology). The MICHELIN Power Pure weighs 2lbs less than rival tires by optimising the construction, profile, and materials. Shaving off 2lbs off the weight of the sport bike tire may not seem like a big deal. However, it makes a HUGE difference. The weight savings is not covered by the suspension, also known as “unsprung weight”. The lighter the bike’s unsprung weight, the easier it is to from left to right, like in chicanes.

As a wheel and tire rotate, its inertia creates a gyroscopic effect. The faster the wheel and tire rotate, the greater this effect is, which is why a rolling tire will balance itself and roll on its own. When it slows down, the effect becomes too weak and it falls over. From a gyroscopic point of view, the same mass has a larger effect with a larger radius than a smaller radius. Michelin claims that shaving 2lbs off the tires has the same effect of saving 6lbs of wheel mass. All of this means that saving weight at the tires will help you get in and out of lean angles faster, also known as “flickability”.

According to Michelin, their Power Pure tires’ 2CT dual compound technology provides more soft rubber on the shoulders and it kicks in sooner also. The compound distribution of the front tire has been set as 25% / 50% / 25%. The harder of the two compounds is the 50% in the center which provides longer lifespan for highway miles. The softer compound on the shoulders is accessible for lean angles starting at 24º. The rear tire compound distribution is set at 40% / 20% / 40% with the harder of the two compounds being the center 20% of the tire. Michelin claims that with lean angles starting at 20º, the soft compound makes up 98% of the contact patch. The shoulders for both the front and rear are slick to ensure maximum grip with lean angles above 40° and the center of the front and rear tires are slick to ensure maximum grip under acceleration and braking.
