Building on many years of experience from collaborations with Bridgestone, Continental, and Renk, among others, Hahlbrock has now produced six sets of GRP road shells for major European tire manufacturers.
The road shells are adapted to the different requirements of the tire manufacturers, but still have the same running surface with a structure molded from ISO standard asphalt. In this way, E.T.R.T.O. aims to standardize acoustic tests for tire manufacturers.
