Michelin Jet XCR road bike tire on a rolling resistance test machine

The Michelin Jet XCR is the fastest mountain bike tire from Michelin. On their site, they describe the Jet XCR as "The fastest: Maximum performance to make your stopwatch crazy". This is something that we like to hear at Bicycle Rolling Resistance as fast tires are what we're always looking for.

We already tested the Michelin Force XC (read our review) and Force AM (read our review) a while back and found these tires to be very strong but not all that fast rolling. The Jet XCR is built from a lighter and thinner 3x150 TPI casing + an extra protection ply that runs from bead to bead. The compound is a GUM-X2D dual compound that supposedly is more optimized towards a low rolling resistance.


As usual, we've tested the rolling resistance and puncture resistance of the Michelin Jet XCR to see if it's as fast as Michelin promised.

All numbers are for a single tire at a speed of 29 km/h / 18 mph and a load of 42.5 kg / 94 lbs.

Use the formula: RR (Watts) = CRR * speed (m/s) * load (N) to calculate rolling resistance at a given speed and load.

Conclusion

Unfortunately, the Michelin Jet XCR isn't the fast-rolling tire we hoped it would be. With a rolling resistance of 33.2 watts at an air pressure of 25 psi / 1.7 bars, it comes in near the bottom of all mountain bike tires that have been tested. It looks like the compound isn't all that different than what's used on the Force XC and Force AM.


As much as we like most of Michelin's road bike tires, we just can't recommend the Jet XCR if you're looking for a fast mountain bike tire. We think the main use of this tire will be for the rear wheel on a fast XC bike, and we feel there are better choices out there for that usage scenario.
