Around The World Report That Wet-Surface
Performance Is A Major Concern When
Purchasing New Tires.
Our new EPC Compound Reduces
Friction-Related Rubber Hardening
Creating More Consistent Wet Braking And
Handling. |

We have
introduced several technologies over the
years to help prevent the deterioration of
wet-surface performance. Our "keyhole sipe,"
for example, adjust the volume of tread
grooves in accordance with the amount of
tire wear.
Our Extended
Performance Compound (EPC) reduces the
deterioration of wet-surface braking and
handling by reducing rubber hardening caused
by the heat of friction.
We initiated a
research program at Bridgestone Corporation
to shed new light on the causes of rubber
hardening. Using the results of this
research, we then developed our new EPC
(Extended Performance Compound) technology.
It's formulated to counteract the hardening
effect of heat that can be caused by
friction. Because it retards the hardening
effect, EPC helps maintain wet-surface
braking and handling.
