“Everything our consumers loved [about the DWS06], we made every category better,” said Bjoern Glaeser, UHP product engineer who headed up the project.
In tests, the DWS06 Plus showed almost a 10% improvement in wet braking and 11% improvement in snow traction from its predecessor, Glaeser reported. More than 4,000 tires were tested in dry, wet and snowy conditions over the last four years to achieve the desired performance characteristics, Glaeser said.
