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 |
