CX/Gravel Tire Test: Vittoria Corsa N.EXT TLR 32

NOTE: This Vittoria Corsa N.EXT TLR 32 was tested as a CX-Gravel tire at low air pressures. You can also find tests of the 26 mm Vittoria Corsa N.EXT TLR and 28 mm Vittoria Corsa N.EXT TLR in the road bike section.

Although the Vittoria Corsa N.EXT is technically a road bike tire, it's also very suitable for use on gravel bikes due to the availability of some larger sizes. The Corsa N.EXT TLR is available in six sizes ranging from 24-622 to 34-622 in 2 mm increments and we see the 32-622 and 34-622 as the best options for light off-roading and the 30-622 and smaller sizes for pure road bike use.

We've already tested the 26 mm and 28 mm versions of the Vittoria Corsa N.EXT and found them to be excellent road bike tires with an emphasis on puncture resistance and wet grip.

We can see the Corsa N.EXT do well as a fast gravel bike tire as wet grip and puncture resistance are far more critical for a large volume road bike tire that's used during the winter months, or gravel bikes that see the occasional off-road moment here and there.

We've already gone more in depth about Vittoria Corsa N.EXT in the 26 and 28 mm tests so let's jump over to the test results and see how the 32-622 Corsa N.EXT TLR does when we compare it to some other 32/34 mm road bike tires and a bunch of more traditional gravel bike tires.

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

Our sample of the 32-622 Vittoria Corsa N.EXT TLR performs very similar to the 26 and 28 mm versions we tested previously. We do see some slight differences, as the 32-622 rolls a bit faster but, at the same time, performs a bit less in the puncture tests. The differences are minor and probably can be attributed to manufacturing tolerances and the margin of error of the tests.

The 32-622 does excel in the wet grip tests as it performs better than the already strong performance of the 26 and 28 mm versions. The increased grip comes from the larger contact patch of the 32-622 version, as well as the slightly lower air pressures we use for tires tested in the CX/Gravel category. We expect both the larger contact patch and lower air pressure to add roughly ~2 points to the wet grip test score.

Compared to other popular road bike tires available in the 32 mm and up sizes, the Corsa N.EXT TLR performs stronger in the puncture resistance tests and very strong in the wet grip tests. It does roll slower than the absolute fastest tires that sacrifice strength and grip for rolling performance.
