The Vittoria Mezcal TNT G+ 2.0 is an updated version of the Mezcal TNT G+ 1.0 that we tested back in 2017 (read review). We checked all the specifications of the new G+ 2.0 version of the Mezcal and it looks like the only thing that changed is the compound that received an update.

Vittoria claims the G+ 2.0 compound used in their MTB tires mainly improves wet grip over the G+ 1.0 version, they do not claim any other improvements. If they sacrificed rolling resistance to improve wet grip, we do not feel this is an upgrade but merely a retuning of the compound.


For this test, we tested the 29x2.25 TNT version of the Mezcal G+ 2.0 as it's the exact replacement of the 29x2.25 Mezcal TNT G+ 1.0 that we tested back in 2017. This allows us to compare Vittoria's G+ 2.0 compound 1 on 1 to the previous version.


The Mezcal G+ 2.0 is now also available as a lighter TLR version that comes with thinner sidewalls and is meant to be used with an inner tube. Be aware the Mezcal is also available as a 26 TPI rigid bead version which is much heavier and we're not sure these are made to the same quality standards as the TNT and TLR versions.


We also tested the Vittoria Barzo TNT G+ 2.0 (read review) which is a good match with the Mezcal as a front/rear set if you need more grip in the front.

Conclusion


  • Vittoria Mezcal TNT G+ 2.0
Performance compared to all other MTB tires
(100% is fastest - lightest - highest - strongest)

We're a bit disappointed because we hoped the Vittoria G+ 2.0 MTB tires performed even better in our tests than the G+ 1.0 MTB tires. Rolling resistance of the Mezcal TNT with G+ 2.0 compound has gone up by 10-15% when compared to the equivalent Mezcal TNT with G+ 1.0 compound (read review). Puncture resistance is nearly the same for both versions with the G+ 2.0 edging the G+ 1.0 out in the sidewall puncture test.


Vittoria claims to have improved wet grip with the G+ 2.0 compound but they did this at the cost of rolling resistance. When looking at our mountain bike overview, the Mezcal TNT G+ 2.0 ends up somewhere in the middle while the G+ 1.0 version stood out as an interesting tire.
