Michelin Power Race Dual Compound Rear Tire
As shown in highlighted areas, Michelin Two Compound Technology is used
in all medium-compound Power Race tires and in the medium soft-compound front
(left).
Besides multi-compound technology, the Power Race copies a number of other
features found in Michelin MotoGP tires. Power Race tires are made from a rubber
formula specifically developed for the racetrack, known as C-RAO (Compounds-RAcing
Optimization). It’s a combination of three 100% synthetic components identical
to those used in MotoGP tires during the 2004 season: proprietary Michelin
Racing Synthetic Elastomers (MRSE) and two additives, Macro-Molecular Compound (MMC)
and High-Technology Synthetic Compound (HTSC).
In addition, virtually the entire Power Race range is manufactured using
Michelin’s highly secretive C3M process, the same used to make MotoGP tires.
Michelin won’t say much about C3M (which stands for carcasse, monofil, moulage
et mechanique), but they will concede that the process consists of a single
step, instead of the seven used in conventional tire production.
With C3M, Michelin can make the tire on a solid insert mold, so that the raw
tire has the same shape as a cured one, which isn’t the case in traditional
manufacturing. This means that precise quantities of tread compound can be
applied with pinpoint accuracy–a feature of critical importance in the
manufacture of a multi-compound tire like the Power Race.
Capitalizing on all this technology, Michelin has produced a tire that is not
only multi-compound, but also one of the lightest front tires on the market (8.5
pounds on average). This minimizes rotational inertia, for better acceleration
and braking performance. What’s more, the combined weight of front and rear
tires is lighter than any other DOT racing tire (21.4 pounds on average),
minimizing unsprung, rotating mass.
It already looks like Michelin has a winner on its hands. The Power Race won
Roadracing World’s on-track shootout test of DOT race tires, featured in the
magazine’s June 2005 issue. Suggested retail for the Power Race ranges from $377
to $526 per set, depending on sizes and compounds.
