Pirelli Cinturato Cross M 33 road bike tire on a rolling resistance test machine

The Pirelli Cinturato Cross Mixed Terrain is the more aggressive version of the Pirelli Cinturato Cross range. As the name implies, the Cross Mixed Terrain is made for a large range of surfaces from hardpack up to the loose stuff, and whether wet or dry.


The Cross Mixed Terrain is very similar to the Cross Hard Terrain (read our review), the only difference seems to be the tread pattern with higher knobs and more room between the knobs to clear mud easier. Both tires are built from the same materials: 127 TPI Tubeless-ready casing with a bead to bead woven fabric reinforcement and the Pirelli SpeedGRIP compound on top.


From the looks of this tire it's probably one of the most aggressive cyclocross tires out there as we haven't seen many with such an open-spaced, and big knobs tread pattern.

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.

Although the Pirelli Cinturato Cross Mixed Terrain is very similar to the Cinturato Cross Hard Terrain, there is a definitive difference in rolling resistance between these tires that gets bigger at higher air pressures. This isn't a tire made for running on asphalt at higher pressures as the tread pattern just doesn't work for that.


If your most important requirement is off-road grip under bad conditions and a tire that can clear mud, the Cross Mixed Terrain will be a good choice. Best of both worlds could be a Mixed Terrain on the front and the Hard Terrain on the rear. Check the CX/Gravel overview page to compare all CX/Gravel tires.
