“Sounds as if Aus is rationalising inventory John. Pity because the HP is a good dirt road tyre with stones around. That said the XM2 is also a tough tyre & designed to take knocks that would damage High Performance summer tyres.”

Higher is better. The Relative Score follows your weights below; category scores do not change.
Wet grip starts at “Important”. Treadwear starts at “Neutral” here: road tests measured it for at most one of the two tires, so it rests on owner reviews. Move the sliders and the scores update instantly.
Only one of the two tires has a score here, so this weight changes nothing in the head-to-head.

Themes extracted from owner reviews found online — not the opinion of TireWheelGuide.
From Reddit, forums and review threads. Not part of our score
Community opinion on the Michelin Primacy HP is divided depending on use case: enthusiasts frequently criticize them for lacking grip compared to dedicated Pilot Sport performance tires, though many appreciate their playful, low-traction slide characteristics on cars like the GR86/BRZ. Owners also note their low rolling resistance and suitability for mild climates, but raise occasional discussions around shoulder cracking with age and their limitation as summer-only rubber.
“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.”
“Sounds as if Aus is rationalising inventory John. Pity because the HP is a good dirt road tyre with stones around. That said the XM2 is also a tough tyre & designed to take knocks that would damage High Performance summer tyres.”
“So long as you’ve got some tread, the stock Primacy HP tires are plenty safe for Bay Area weather all year ‘round. Just don’t drive anywhere that gets real winter weather or freezing temps. I’d avoid trips up to Tahoe in January. And don’t climb Mt. Diablo or Mt. Hamilton when they get their occasional dusting of snow. (I live in upstate NY now, so I’m familiar with tires & winter conditions …but I’m also a Bay Area native.)”

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.
Handling is the exception: road tests measure it inside the dry and wet scores, so its own row comes from owner ratings only and starts as less important.
