“You will notice the difference, but if you don't track, autocross, or canyon carve, I wouldn't bother. You don't have to stick with Primacy but it's not worth the PSS. The only reason I would go PSS in that instance, is if the price is similar to Primacy HP (it might actually be similar). If you drive in snow at all I would not go with PSS. Do not go with anything more aggressive than PSS for day to day street driving. There are people who daily drive more aggressive RS3s, RE-71s, ZII Star Specs, etc. but they track/autocross, know the limits, and take it easy around standing water.”

Tire A

Michelin Primacy HP

Mixed

Community opinion on the Michelin Primacy HP is divided. While some enthusiasts view them as lacking grip and inferior compared to Michelin's performance-oriented Pilot Sport line, others appreciate them as stock tires for daily driving or playful street handling due to their predictable breakaway and low rolling resistance.

“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.”

How do we compare tires?

Every category score blends two independent signals. 60% comes from professional tire tests (braking distances, lap times, noise measurements), each result compared with every other tire in the same test and newer tests counting more. 40% comes from owner reviews found online, adjusted for how generously each site rates. Both use one scale: the average tested tire gets 70, the best 100. When a tire has only one of the two, the missing half is estimated from the other and the score stays closer to average; with no road test and fewer than five owner reviews it gets no score yet.

Community buzz from Reddit and forums is shown for context only — it never changes the score.
