SILCA Protocol 32" RCG-3 Mixed Terrain Gravel Tire - 32x2.4

More grip, more puncture protection, and all the speed

The RCG-3 is the successful result of SILCA's mission to make the best gravel tire on the planet.

Features

• Fast gravel tire designed for demanding Category 3 gravel racing
• Combines fast XC MTB tire characteristics with an ultra-fast road tire casing
• Supple Pulsar casing for low rolling resistance and high comfort
• Robust puncture protection with an under-tread breaker
• High impact resistance without adding excessive weight or sluggishness
• Designed to minimize hysteretic losses and maintain rolling efficiency
• Excellent traction on unpredictable and harsh terrain
• Tightly spaced center knobs for smooth, fast rolling
• Progressively larger and taller knobs toward the shoulders for cornering stability
• Increased buoyancy and contact patch when cornering
• Optimized to roll smoothly on the tread rather than deforming excessively on the casing
• Tuned for slightly higher tire pressures
• Improved contact patch stability and reduced over-deflection
• Enhanced pinch-flat protection without sacrificing traction or handling
• Overall combination of speed, suppleness, durability, puncture protection, and resilience
• Minimum Sealant Fill Recommendation: 135ml

RCG-3 Architecture
The same tightly spaced, elongated center knobs as the rest of the RCG-3 family, growing in size and height toward the shoulder for buoyancy and contact patch through the corner. Sized to 32 x 2.4, that pattern sits on a longer, wider footprint than a 700c tire can reach.

An Emerging Advantage
In some scenarios, 32-inch tires offer superior rollover and reduced real-world rolling resistance over rough terrain compared to smaller wheels. Their larger diameter can create a shallower angle of attack against obstacles, lowering the energy required to clear bumps.

Ideal Conditions
Purpose-built 32-inch tires perform on rough, mixed terrain race days, where rollover and stability matter as much as outright speed. Choose it when your frame has the clearance and the course rewards float and comfort over the lowest possible weight.

Specifications

• 120 TPI
• SealSkin Protection
• Fastest Pulsar compound

Protocol Tire Technology

Pulsar Compound
A high performance rubber and silica race compound engineered to hold rolling efficiency, grip, and durability in balance rather than trading one away for another.

Race Casing
A race casing architecture developed around modern tire pressures, so the tire keeps its shape and its ride quality at the pressures wide rims actually run.

SealSkin
Enhanced puncture protection for terrain that asks more of the casing, adding durability where the ground is rough enough to make it part of being fast.

Tubeless Ready
Engineered for modern tubeless systems from the bead out, so sealant, valves, and lower pressures all work the way they were meant to.
