The EDGE-22 upends convention with an open center design that adds accessible cornering edges closer to the center of the tread for instant cornering grip when turning. As lean angle increases, with the center edges remaining engaged with the terrain, the outer row knobs kick in, doubling the cornering edge engagement to hold the cornering line in ways that tires with a single row cornering knobs can’t match.

What’s unique

Instantaneous cornering grip: center knobs are realigned to create the spacing necessary for a set of cornering edges in the central tread zone, allowing the edges to dig into the terrain immediately when leaning into corners.


Dual cornering edge engagement: with the central set of cornering edges remaining locked in with the terrain, lean further, and the outer knobs kick in to add an extra set of cornering edges digging into the terrain simultaneously.

How EDGE-22 Achieves Dual-Edge Engagement:

With open center spacing

Two sets of cornering edges are engaged simultaneously (shown in 3 & 4) for cornering grip during the crucial range of lean angles. The EDGE-22 retains the familiar outer row knob arrangement, with sufficient spacing for the outer cornering edges to dig into the terrain during high lean angle cornering.

It’s OK to be brake happy

The shape and positioning of the EDGE-22 knobs provide plenty of stopping power to reign in control. The two rows of central knobs are strategically positioned well within the perimeter of the tire’s contact patch so plenty of accessible braking edges are available to slow things down. Additionally, while the leading edge ramp on each knob enhances rolling smoothness, during braking, the ramping shifts to reinforce each knob, preventing each knob from buckling under load for precise and reliable braking performance. Combined, the EDGE-22 makes no compromise when braking.

The Construction

EDGE-22 utilizes Tioga’s MAGNUM 120 casing, a densely woven 120TPI casing, reinforced with a thin bead-to-bead protection layer to balance sidewall suppleness and casing conformity with ample durability for front tire use.

Synergy Dual Compound Rubber places softer rubber on the sides to further increase surface friction on the outmost knobs, while the harder rubber in the central zone lowers rolling resistance and increases tread life.
