The "Bi-Compound Technology" includes the use of two different elastomers in the tread. On the outside: a new type of hybrid elastomer allowing perfect grip on dry ground and on the inside: a new blend of new ingredients with specific "functional elastomers" and silica to allow grip and braking on wet ground.
