Michelin Primacy HP vs Pirelli Cinturato P7 All Season Run Flat — Compared

“PSA: The Stock Michelin Primacy HP tires are SUMMER tires! I figured, given that winter has finally arrived in much of the US, I'd make a quick reminder that this car ships in the US with summer only tires. I've noticed that this fact is rarely mentioned in threads about snowy weather or winter tires, and I myself didn't realize this until just before I bought mine. A quick explanation for the non-car guys in the sub. Most cars in the US sell new with all-season tires mounted. These are tires that maintain a balance to allow them to work OK on hot dry pavement, in the rain, and in winter weather. Not great, but OK. They're a jack of all trades, master of none In contrast, these cars (at least in the US market) shipped with summer-only tires. This means that they are NOT OK for use in winter weather--even just cold dry pavement. Summer tires are made of a compound that is too hard in cold weather, therefore not sticky even on clean pavement. In addition, they often lack the open spaces in the tread that are necessary for good snow traction.”
