Tread Designs

The function of the tread is to increase the durability and operational life of the tire. It is the pattern of the tread combined with specially formulated rubber compounds that gives each tire its specific performance characteristics.

Recognized as a leader in tread design, Yokohama is continually researching new tread compounds and innovative tread patterns to improve tire performance and fuel efficiency.

The Yokohama tread designs below are examples of basic types used throughout the industry. Yokohama combines the best of these basic designs, as in the rib-block example, to create a wide range of tires that enhance quality and durability to meet all consumer needs.

	Rib-Block Type This pattern combines block-type tread in the center with a shoulder rib design and has the following advantages:
		Low rolling resistance
		Comfortable ride
		Relatively low noise generation
		Good traction on snow or in muddy terrain

	Lug Type In this pattern, the grooves are cut across the tread, and has the following advantages:
		High braking force
		Excellent traction on unpaved surfaces

	Block Type In this pattern, the grooves are cut across the tread, and has the following advantages:
		Outstanding braking force and traction
		Good traction on snow or in muddy terrain

	Rib Type In the rib-type pattern, the tread and grooves follow the circumference of the tire and have the following advantages:
		Low rolling resistance
		Comfortable ride
		Good Steering
		Relatively low noise generation

	Combined Block-Lug Type This pattern combines a rib-type in the center with a lug-type design and has the following advantages:
		Good steering stability and less side slippage than the rib tread
		Excellent traction and braking force
		Suitability for paved and unpaved surfaces
