The Pirelli Cinturato Gravel M (Mixed Terrain) is a gravel bike tire with a rough-looking tread pattern. The tread pattern of the Gravel M looks like it should handle almost any condition you might encounter with a gravel bike. Thanks to the near-continuous spacing of the center knobs, it should even be a decent performer on a large range of harder types of terrain.

The Gravel M is closely related to the Gravel H (Hard Terrain) (read our review) that we tested a while back. Both tires come with the same tubeless-ready 127 TPI casing with an extra layer of bead-to-bead protective fabric and the same single compound Pirelli SpeedGrip compound that, according to Pirelli, is tailored for all weather conditions and wet or dry terrain.


As the construction is nearly the same, and if the compound is the exact same mix, the performance of both tires should be quite close in most of our tests. The most interesting test will be the rolling resistance tests, as we expect the Gravel M to be a harder rolling tire based on its tread design.


Both tires are also available in the exact same sizes: 35-622, 40-622, 45-622, 45-584, 50-584. This is a test of the 40-622 version as that's probably the most widely used size for gravel bikes.

The CX/Gravel section is a multi tire size section, air pressures have been adjusted to the measured casing width.

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.

The Pirelli Cinturato Gravel M is a decent performer in our tests. Given its rough tread pattern and excellent knob height, it should be a good gravel bike tire for a wide range of conditions. Of course, this isn't the fastest rolling tire out there, but it's definitely still acceptable if you're not looking for an all-out racing tire.


If you're looking for a gravel bike tire that doesn't need changing between the seasons, the Pirelli Gravel M might be one of the best choices out there.
