Michelin introduces four new Pro4 tires

Michelin Pro4 Limited

The Pro4 Limited uses the same casing and tread as the Pro4 Comp, but eliminates the puncture-protection belt to save 15 grams. Michelin claims that this change drops the rolling resistance of the 165g Pro4 Limited by 20 percent over the Pro4 Comp, due to the reduction in mass and the elimination of the densely-woven nylon belt.

Like the Pro4 Comp and Pro4 Grip, the Pro4 Limited will sell for $79.99. It will be available in about a month. We did not test it.

Michelin Pro4 Tubular

Michelin has not offered a tubular in the U.S. in over a decade. This new tubular will have a 290tpi cotton/aramid casing and will sell for $119.99. In 23mm, it will weigh 280g, and in 25mm, the weight will be 295g. Ag2r La Mondiale rode it in Paris-Roubaix and the Tour de France in 2012.

The puncture-protection strip and tread are hand glued on. The tubular has a different tread compound than the other Pro4 tires; since the different tire shape results in a different shape to the contact patch, a tread compound more suited to that has been chosen. Michelin claims that in a round shape of a tubular tire, the cotton casing is more flexible than a nylon casing, thus the choice of cotton with aramid fibers interspersed for increased cut resistance. Look for our testing of this tire in the future.
