Metzeler K3 Racetec Interact Rear Tires

General Features:

• The new Racetec adopts INTERACT™ technology, the latest evolution of the patented 0° steel belt
• The new winding process of a 0° steel belt reduces the contribution made by belts and carcass to stress resistance all along the profile
• Lower tension in the crown area creates more flexibility and the tire can adapt itself better to the road surface, enlarging its footprint
• High steel belt winding tension in the shoulder area ensures maximum and uniform pressure on the contact patch: the trajectory is therefore always precise, without any deviation

Tread Design:

The tread has the same design as Racetec K0, K1, K2, DOT racing tires. The performance-oriented development of land/sea ratio distribution respects FIM Supersport regulations, and most of grooves are concentrated on mid-lean area, leaving shoulders slick-like.
Pattern design has been developed to enhance up to excellence:

• Dry grip
• Consistency of performance
• Wear regularity through maximized tread compactness
• Line holding
• Stability

The result is therefore a performance of the tire nearly like a slick, maximizing the rubber on the ground. 

Structure:

The application of CMT (Contour Modeling Technology), tested in competitions, guarantees fast corner entry and stable and precise trajectory for a progressive cornering behavior.
On the rear, the differentiated radii distribution and a flatter shape at lean zone gives maximum cornering support and higher stability when accelerating out of corners.
The structure of Racetec K3 is strictly derived from the Racing Supersport version, with optimizations aimed to improve the road performance, with particular focus on the stability on straight line.
Metzeler has deployed the most innovative technologies to Racetec:

• Intelligent Tensioning Technology (differentiated tensioning of carcass and belt across x-section) to  widen the contact area at lean
• Patented 0° Steel Belt construction that grants a higher dimensional stability in every condition of use

Compound:

Hi-performance chemicals, combined with an enhanced Curing system give the tire:

• high performance stability, both on road and on racetrack
• fast warm-up
• regular wear, even at high temperatures coming form prolonged use or severe racetrack conditions.

(W-) rated for speeds of 168+ mph.
