GREENVILLE, S.C. (June 5, 2006) — Michelin Retread Technologies Inc. has introduced a retreaded tire design that it says can “regenerate” its tread as it wears.
The Michelin XDA Hypersipe retread has molded tread features on both the top and bottom of a precure tread band. Sipes molded in 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 about half-tread depth and last to the last useable 32nd inch of tread depth, Michelin said.
Research for the tread began in 2004, and it is now ready for production at Michelin's Covington, Ga., plant. The expansion of that plant, which will be completed next month, will double its capacity and include the technology needed for the Hypersipe tire.
“The Michelin Hypersipe maximizes the potential of precure retreading,” said John Melson, research director for truck tires at Michelin Americas Research Corp. “The underside of the tread package had been a forgotten frontier for innovation. Now it's delivering a real performance benefit that helps maintain the traction of the retread consistently over its entire life cycle.”
