Uses: an important part of the Pirelli process all-steel radial tire manufacturing and gives the tire the best outer contour shape at any speed, keeping the shape unchanged.
Main points: reduces rolling resistance to save fuel, increases mileage, improves tire heat and renovation rate, reduces tread deformation for increased security at high speeds; production uses φ90 cold-feed extruder to cover rubber on steel wire belt, then cools and curls on flange-type reel.
