“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.

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.
“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.”
“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.)”
“I have these tires on my 2013 GL550 and they handle really well here in Chicago. They are a little loud for me, but do great in the snow and rain.”

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.
