MICHELIN PRO4 Race Service Course Bicycle Tire

The MICHELIN PRO4 Service Course delivers the best trade-off between sports performance and long
tyre life. The achievement of the engineers is to have simultaneously enhanced its speed, safety,
agility and resistance.
The MICHELIN PRO4 Service Course is not only safer but it is also an average 16 percent faster when
cornering on wet road surfaces*.
These improvements were achieved thanks to its optimised dual-compound technology which features:
• Wider lateral bands for optimal grip at all angles of lean,
• New compounds incorporating new elastomers and silica for extra grip at the shoulders.

The tyre’s new, more pointed profile optimises the contact patch when leaning into corners for extra
grip, as well as enhanced agility.
At the same time, the specific compounds employed by the latest
dual-compound technology provide superior rigidity for the central
part of the MICHELIN PRO4 Service Course’s tread band – the part
of the tyre which is exposed to the biggest constraints – for even
longer tyre life.
Finally, the MICHELIN PRO4’s resistance to cuts, thanks to the
presence of a nylon high-density breaker beneath the tread,
considerably reduces the risk of perforation.

Michelin’s new Pro4 series tires are built on the same 110tpi casing as the venerable and exceedingly very popular Michelin Pro3, however with a some important changes.

Michelin always uses technology that comes from thier lastest MotoGP tires.  The Pro4 corners better and rolls faster, but is also more durable, becuase it has a more pointed profile, which comes directly from MotoGP racing.

The new profile, which creates a sharper angle from tread center to sidewall, allows the tire to lean quicker into corners and offers a larger contact patch once on its side. Grip is said to be increased 13 percent, and cornering speed in the wet by 16 percent. On our circular test track, lean angle in the wet could be increased from 21˚ to 27.5˚ before slipping.

A new dual-compound tread has a harder center than before, increasing wear life. And a nylon breaker beneath that tread improves resistance to cuts and punctures.
