What is it
The Vittoria Mezcal is a fast, dry conditions pure bred XC race tire that has a low profile, densely spaced knob configuration with a defined center ridge tread for low rolling resistance, plus multiple braking and climbing edges and capable side knobs. The sidewall is measurably softer than the rest of the tire, which is designed to enhance grip and cornering traction.

All told, the Vittoria Mezcal comes in nearly 20 configurations, ranging from recently released 29×2.6 and 27.5×2.6 wide trail versions, to super XC pinner 2.1 widths in 26 (yes, 26), 27.5 and 29er. Mtbr tested a 29×2.25 TNT Vittoria Mezcal version that features four compounds (4C) layered together in a way that’s intended to increase overall tire versatility. This includes G+Isotech, Vittoria’s unique Graphene compound that’s claimed to increase speed, and improve grip, durability, and wear resistance.
On the Mtbr Park Tools DS-1 Electronic Scale the Vittoria Mezcal weighed 744 grams (34g over claimed weight). When mounted on a Stan’s ZTR Crest S1 aluminum wheels, which have a 23mm internal rim width, actual tire width measured by the Park Tools DC-1 Digital Caliper was 2.22 (versus the advertised 2.25). Mtbr tested the Vittoria Mezcal on a variety of trail types, including hardpack, loose over hard, and rocky high alpine terrain. Keep reading to find out how it performed.

It doesn’t take a tire scientist to determine best use for the Vittoria Mezcal. With its low profile, densely spaced, small-block knob configuration, and defined center ridge tread, the Mezcal is meant for dry-condition, high speed XC racing. And indeed, it rolls fast – noticeably fast. During testing on a variety of Colorado trail terrain, ranging from smooth kitty litter to chunky no-flow, this 29×2.25 Vittoria Mezcal just wanted to get up and go. The near continuous center tread behaves similar to a semi-slick, easily maintaining speed even when the trail is trying to slow you down.

The Vittoria Mezcal also corners surprisingly well despite its minimalist tread design. The incrementally taller side knobs utilize a dual-shape design with ramps on the slightly more inset knobs to help maintain rolling speed, while the far-outboard knobs are squared off to better claw into terrain. The net effect is a tire that’s comfortable and predictable at aggressive lean angles, but not at the expense of its ultimate goal — crossing the finish line first. Whether it was loose over hard, Rocky Mountain loam, or Colorado chunk, I felt confident diving into tight turns and high-speed berms. And when the Vittoria Mezcal tires did break loose, it was usually predictable and composed, leaving time for correction and/or compensation.
The Vittoria Mezcal also gets high marks for durability, which is in part credit to the G+ Graphene compound, which according to Vittoria allowed the tire maker to remove some of the material barriers of rubber. Surely there’s some hyperbole in there, but whatever they did with this tire, it’s resulted in impressive tread life. After several hundred miles of hard testing, all knobs were present and accounted for. It’s essentially the same story for the sidewall, which has suffered some scuffing, but is otherwise intact.
Where Mtbr didn’t love this tire was under hard straight-line braking and while trying to power up steep, loose terrain. In both cases the rear tire tended to break loose early, meaning you had to plan ahead during rapid speed scrubs, and really focus on keeping evenly-weighted body position during tough uphill grunts. That’s certainly not a deal breaker for a tire in this class. Low rolling resistance comes with a price. But the Vittoria Mezcal certainly benefits from being driven by a skilled pilot. If you’re still learning the nuances of subtle brake modulation and technical climbing, you might want to seek out a tire with a little more center tread bite such as the Hutchinson Toro or Maxxis Ikon, which are also part of this XC tire shootout.
We also managed to puncture both front and rear at almost the exact same time, and neither would completely seal due to puncture size. The fact that both tires failed along the center tread on the same trail section likely means it was a particularly sharp rock (and/or some particularly poor bike piloting). But it’s also clear evidence that the Vittoria Mezcal is not indestructible. Indeed, like all the tires in this class, a certain amount of line choice precision is required.
Bottom line, the Vittoria Mezcal is a tool for the job of going fast. And while that comes with some drawbacks, they don’t outweigh this tire’s ability to get that job done. It’s a stellar rear tire option, and can be run up front so long as the pilot understands its strength and limitations.
