Vittoria Tire Pressure — Correct Pressure for Corsa Pro, Terreno, Mezcal and Mazza

Vittoria's Casing Architecture and How It Affects Pressure

Graphene 2.0, TNT tubeless construction, and 4C compound — what each means for the pressure you should run

Vittoria organises its tire lineup around three casing technologies that directly determine the pressure a tire can safely use and the range in which it performs best. Knowing which casing your tire uses is more important than knowing the model name, because two Vittoria tires with the same name in different generations can have meaningfully different pressure ranges.

Graphene 2.0 (G+)

Graphene 2.0 is Vittoria's reinforcing compound, integrated into the rubber matrix of the casing and tread. It increases tensile strength and puncture resistance without adding significant weight. The practical pressure consequence: Graphene 2.0 tires handle the full sidewall-marked pressure range without casing degradation at the top end, and maintain structural integrity at lower pressures than equivalent non-graphene tires from other brands. All current performance Vittoria tires carry G+ marking on the sidewall.

TNT — Tubeless No Tube

TNT is Vittoria's tubeless-specific casing. The sidewall is constructed to hold air without a tube, using a denser rubber layer that eliminates permeability and provides the bead lockup needed at low pressures. Importantly, TNT-cased tires are not simply tubeless-ready — they are engineered for tubeless and run measurably lower minimum pressures than equivalent tubed setups, typically 8–12 PSI lower across road, gravel, and MTB categories. A non-TNT Vittoria tire can sometimes be run tubeless, but the result is less predictable and the pressure floor is higher.

4C Compound Layering

4C indicates four distinct rubber compounds in a single tire: a harder centre tread for low rolling resistance, softer shoulder compounds for cornering grip, an inner layer for puncture protection, and the outer cap compound. 4C does not change the pressure you should run — it is a compound architecture choice — but it explains why some Vittoria tires feel dramatically different at the same pressure in corners compared to budget alternatives.

Vittoria Road Tire PSI by Model and Width

Corsa Pro, Corsa N.EXT, Corsa Control, Rubino Pro and Zaffiro — recommended ranges by width and tube type for a 70–85 kg rider

All values are for a 70–85 kg (155–187 lb) rider. Add 5–8 PSI across the board for riders over 90 kg; reduce by 5–8 PSI for riders under 60 kg.

Corsa Pro: Vittoria's Benchmark Race Tire

The Corsa Pro is Vittoria's flagship road tire and the model whose pressure matters most to get right. It is available in both tubed and TNT tubeless versions, and the pressure difference between the two is significant — roughly 8–12 PSI lower for the TNT tubeless setup at the same width and rider weight.

At 700×28mm, most road riders in the 70–80 kg range find the optimal tubeless Corsa Pro pressure is 65–72 PSI. This sits well below what the sidewall physically permits, and well below what most riders ran a decade ago on narrower tires, but it is where Vittoria's own rolling resistance data shows lowest loss. Newer Corsa Pro tires include a QR code on the sidewall linking to Vittoria's online pressure calculator — scanning it for your exact weight, rim internal width, and surface is the fastest way to get a personalised number.

Corsa N.EXT and Hookless Compatibility

The Corsa N.EXT is Vittoria's hookless-rim-compatible road tire. The 72.5 PSI ceiling applies when mounted on hookless rims (standard for many carbon aero wheelsets). On hooked rims, the tire can be run up to its full sidewall rating. This distinction matters if you recently upgraded wheels — do not exceed 72.5 PSI on hookless rims regardless of the tire's stated maximum.

Vittoria Gravel Tire PSI — Terreno and Mezcal

TNT tubeless construction across the Terreno range allows pressures that would cause pinch flats in tubed setups

Choosing Between Terreno Dry, Mix and Zero

The three Terreno variants differ in tread pattern and compound, not in casing — all use Graphene 2.0 TNT. That means the decision of which Terreno to run is about terrain grip, not structural pressure limits. The Terreno Dry's low-profile centre tread rolls fastest on hardpack and compressed gravel; run it at the top of the tubeless range. The Terreno Mix's intermediate tread excels on mixed surfaces at mid-range pressures around 28–34 PSI tubeless for 700×40mm. The Terreno Zero is the fastest-rolling of the three on loose-over-hard terrain and benefits from slightly higher pressure than the Mix to maintain its tread geometry.

Mezcal: Gravel Racing at Trail-Bike Pressures

The Mezcal occupies a unique position — technically an MTB-size tire but tuned for cross-country racing and endurance gravel riding. In its TNT tubeless form, many racers run it at 20–24 PSI at 29×2.1", which is lower than most gravel tire guides suggest and closer to trail MTB territory. The Graphene 2.0 casing makes this viable by providing structural resistance against casing roll at these pressures.

Vittoria MTB Tire PSI — Mazza, Barzo, Morsa and Martello

Enduro and trail casings with real-world tubeless pressure ranges from testing and rider use

Mazza Pressure in Practice

The Mazza is Vittoria's primary enduro tire and carries significant sidewall volume — the 27.5×2.4" is a genuinely wide casing. Riders running 70–80 kg body weight typically find 20–23 PSI tubeless rear and 18–21 PSI tubeless front covers most trail conditions. Riders over 85 kg should shift to the upper range (24–26 PSI rear) to prevent casing roll in high-speed corners. The Mazza's compound is sticky enough that very low pressure (under 18 PSI) does not meaningfully improve grip but does increase the risk of pinch damage and rim strikes on technical terrain.

Tubed vs. Tubeless Pressure Difference Across Vittoria's Lineup

The 8–12 PSI gap that changes what pressure you should actually run

Vittoria's TNT casing enables a consistent pressure reduction of 8–12 PSI below the equivalent tubed setup. This is not a marketing claim — it reflects the genuine elimination of pinch flat risk (which sets the lower bound of tubed pressure) and the improved casing compliance at low pressure that the denser TNT sidewall provides.

If you are running a tubed version of a Vittoria TNT tire — or a non-TNT Vittoria in a tubeless setup without the correct casing — your actual safe minimum pressure is approximately 8–12 PSI higher than the TNT tubeless figures in the tables above. Running tubed tire pressure references for a TNT tubeless setup wastes the most important advantage of going tubeless.

Vittoria publishes a dedicated tire pressure calculator at vittoria.com that accounts for tire model, rim internal width, rider weight, e-bike usage, terrain, and conditions. It is the most accurate source for a specific pressure given your exact setup.

Front/Rear Pressure Split and Width Interaction

Vittoria's published 3 PSI front-lower recommendation and how rim width changes the effective tire width that determines pressure

Vittoria explicitly recommends setting the front tire 3 PSI (0.2 bar) lower than the rear across all disciplines. This is a narrower split than some brands recommend — the physics is that the rear bears approximately 60% of total rider weight, but overweighting the rear/front correction often sacrifices front traction on Vittoria's relatively compliant Graphene 2.0 casings. The 3 PSI rule holds across road, gravel, and MTB tires.

Rim internal width changes effective inflated tire width, which changes the correct pressure. Mounting a 28mm Corsa Pro on a 21mm internal width rim produces a narrower, rounder profile and requires slightly higher pressure (3–5 PSI) compared to the same tire on a 25mm internal rim where the tire spreads to a flatter, more square profile. If your wheelset uses 25mm+ internal width rims, shift 3–5 PSI lower from the table values above.
