CX/Gravel Tire Test: Vittoria Terreno Zero TNT G+ 2.0 37

The Vittoria Terreno Zero is a cx/gravel bike tire with a smooth center tread and some minimal knobs on the sides. To be fair, this tire looks more like a road bike tire than a cx/gravel bike tire which is probably why Vittoria called it the Terreno Zero.

Vittoria's Terreno range of cx/gravel bike tires come in 4 different versions: Zero, Dry, Mix, and Wet. These names are clear and immediately give you an idea of the intended use of these tires. When looking at rolling resistance, we would expect that the Zero is the fastest but as you can see below that isn't true.

When comparing all specifications of the Zero, Dry, Mix, and Wet versions of the Terreno, it's clear they all use the same construction and compounds but with a different tread pattern applied. Read on below to find out why the Terreno Zero rolls slower than the Terreno Dry (read our review).

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.

Conclusion

To our surprise, the Terreno Zero rolls slower than the Terreno Dry (read our review) that we tested a couple of weeks back. The reason behind this is the much thicker tread of the Terreno Zero that we measured at 4.0 mm while the Terreno Dry measured just 2.8 mm thick. The thicker tread also shows in the puncture test as the Zero scores 11 points while the Terreno Dry scored just 8 points.

We don't think the Terreno Zero is a bad tire but when not being completely informed, you probably choose the Terreno Zero over the Terreno Dry when looking for a faster tire. Just know the trade-offs between these tires and pick wisely. Compare for yourself on the CX/Gravel overview page.
