These big Michelins were superb on a large Peugeot 508SW estate car, with a very torquey turbo Diesel engine. They inspired confidence whether it was just me driving alone, or fully loaded with five on board and family stuff loaded in the back. There was plenty of grip for cornering, acceleration, and braking whether the road was dry, damp, or soaked with rain; they tracked straight and without vibration on the autostrada-motorway, and made it easy to guide this big car around sweeping bends on narrow country roads. I did not drive this rental car in snow or ice, but I would expect to change from the Primacy HP to winter tyres before the likelihood of such conditions, if I owned the car, because the tread pattern and rubber compound seem to be optimized for spring, summer and autumn. They are very quiet at all reasonable road speeds and on most surfaces; no squealing. The only time they lost traction was when turbo boost came online while heading uphill in first gear (the most difficult situation for front-wheel-drive), during which time they scrabbled for grip for a few seconds but continued to haul the heavy car uphill with a lot less drama than I have experienced with other, lesser tyres. Michelin Primacy HP may be expensive, but you should get as good as you pay for and be suitably encouraged to maintain correct pressures and rotation to maximize their life.
