CX/Gravel Tire Test: Vittoria Terreno Dry TLR G+ 2.0 40

Vittoria's Terreno range of gravel bike tires comes in many different flavors and sizes. When you're interested in the Terreno range, the first step you'll have to make is picking the right "flavor" of the Terreno, and the base choice here seems to be the "Dry" version we have on test here. Also available is the "Zero" for even drier conditions, the "Mix" for mixed conditions, and the "Wet" for wet conditions (obvious).

Within the Vittoria Terreno Dry range, we then find a "rigid", a "folding", a "tubeless TNT", and a "tubeless TLR" version. We see this more often with other manufacturers, but we can't find much information on Vitorria's website explaining the differences between these versions. As we don't have the information, we can't tell much more about them, but we suggest focusing on the "tubeless TNT" and "tubeless TLR" versions if you care about performance.

This is a test of the Terreno Dry "rubeless TLR" in the 40-622 size. The "tubeless TLR" version comes with tan sidewalls and is 40 grams lighter than the "tubeless TNT" version which comes with grey sidewalls. One thing we're sure of is that the TNT version comes with reinforced sidewalls, and it should be the easiest to use in a tubeless set up.

We've already tested the Tubeless TNT version of the Terreno Dry in the 33-622 size (read our review) a couple of years back. Even though they are different tires, it should give us some insights into the "tubeless TLR" and "tubeless TNT" versions.

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

The 40-622 Terreno Dry performance in the lighter "tubeless TLR" version seems off as it comes in much slower than the 33-622 "tubeless TNT" version that we tested back in 2020. We see some obvious differences, like the sidewalls that are thinner and easier to puncture. The tread, on the other hand, is a bit harder to puncture and might indicate the use of some kind of anti-puncture strip under the tread.

The biggest issue we see here is that, for an uninformed buyer, we would have assumed the "tubeless TLR" version to be faster than the "tubeless TNT" as it's lighter and seems to come with less protection. That doesn't seem true, and from our test results, we recommend always going with the "tubeless TNT" versions if you're interested in Vittoria off-road tires.
