Tire tread with highlighted zones: 1 green shoulder, 2 purple edge, 3 blue intermediate, 4 red center

Tire Tread Block Regions

Green — Shoulder Block

Cornering stability, resists lateral forces, staggered edges to cut noise.

Red — Center Block

Primary contact patch for straight-line stability, braking, and acceleration traction.

Blue — Intermediate/Transition Block

Bridges forces between center and shoulders; balances handling and comfort, reduces harmonics.

Purple — Edge/Shoulder Lug

Angled outer lugs bite into loose terrain; open voids self-clean and add grip in ruts or snow.

CYAN — STONE-EJECTOR / SIPING

Small tie bars and ejectors clear rocks, add wet-grip bite, and stabilize the tread so it wears evenly without raising noise.

FEATURES FEATURES FEATURE

When you ask a tire to do two things at once—say brake and turn, or accelerate and turn—the available grip doesn’t simply split 50/50 between them. Instead, the tire’s capability drops off non-linearly. This is because traction is not additive but vector-based: the forces act together inside what’s called the traction circle. For example, if the tire is already using 80% of its grip to corner, you don’t have 20% left for braking in a straight-line sense—you actually have much less, because the cornering load curves the limit in.

The closer you get to the edge of the tire’s friction envelope, the faster it falls away, meaning the combined forces cause the tire to break loose earlier than you’d expect if you treated grip like a straight-line budget. That’s why professional drivers modulate inputs—easing off the brakes before turning in, or unwinding the steering before going full throttle—because trying to demand two maximums at once will overwhelm the tire almost instantly.
