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.

CarbonBead BeadLock
Carbon fiber bead technology that keeps the tire dimensionally stable across its whole life, so the width you measure at installation is the width you keep.

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.
