Michelin Primacy Alpine PA3 Radial Tire - 205/60R16 92H Building on the fuel efficiencies of its predecessor, the Primacy  Alpin  PA3  tire helps to use even less fuel, thanks to a rolling resistance that has been reduced by 7%. Primacy  Alpin  PA3  tires offer a 10% gain in acceleration and handling characteristics in snow as a result of more sipe edges biting into snow and ice from 3-D StabiliGrip Technology  with its bidirectional, auto-blocking, and variable-geometry sipes. The Helio Compound  of the Pilot  Alpin  PA3  tire allows for stopping distances of up to 5.6 feet shorter than its predecessor on wet road surfaces.
