Michelin brings imagination to life as Michelin Retread Technologies (MRT) announces the first self-regenerating retread - the Michelin® XDA® Hypersipe™. The Michelin XDA Hypersipe retread uses Michelin-patented tread design and siping technology to mold tread features on both the top and bottom of a Pre-Cure® tread band. Sipes molded into the bottom of the tread appear as the tire wears; giving improved worn traction over the life of the retread. The bottom sipes appear at approximately half tread depth and last literally down to the last usable 32/nd of tread giving the retreaded tire better traction at reduced tread depth and allowing the tire to be removed from service later in life.
