“So apparently Michelin Primacy 5 has been released in Australia - not in all sizes. My tyre size 235/40R19 won't be available until April 2026 - omg lol. I told them to take that size out of the website. Talk about slow rollout considering its been out in Asia for a few months.”

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.

Community sentiment for the Michelin Primacy 5 is broadly positive, with drivers consistently praising its low cabin noise, smooth ride comfort, and stable wet performance. However, some users report mixed experiences, noting surprisingly harsh ride quality, faster-than-expected tread wear, or limited initial size availability in certain markets.
“Michelin Primacy 5 or new Primacy 5 energy I need to replace 2 of my tyres and was having a look online and saw that Michelin have released new Primacy 5 'energy' tyres. I was going to get the normal Primacy 5s as I have two already on the front of my car and am pretty pleased with them. However the Energy version has A for both fuel efficiency (normal ones have B for fuel efficiency) and wet grip and is quieter than the Primacy 5s according to black circles and is only £8.50 more per tyre. Given that they're designed for EVs (but website does mention that you get lower fuel consumption for combustion vehicles too) would I notice any difference on my diesel Passat estate? I mainly drive motorways/A roads and am pretty sensible when it comes to driving and I mainly want something that'll last ages and is good for fuel consumption. So should I go for the Energy edition or would I not experience any difference? Many thanks Read more”
“Am avut primacy 4 pe o electrica. Destul de dezamagit de faptul ca dupa ~ 28.000 km s-au tocit rau de au ajuns cam la 3 mm. Placute la condus, silentioase, dar nu cele mai aderente. Pilot sport 4 pe aceiasi electrica cu primacy 4. Huruie de te doare capul. Aderenta nu o simt neaparat wow fata de primacy 4. Nu le mai suport si abia astept sa le trec pe iarna, oricum asta fiind ultima incaltare cu ele. Pe o termica am primacy 5, si sunt cele mai ok din experienta mea. Cele mai silentioase si aderente din cele 3. Dupa 20.000 km uzura a scazut cam cu 1 mm. Recomandarea mea e sa alegi primacy 5 fara ezitare.”
“205/55 R16 - A common size missed and 205/60 R16 launched. Customers won't be able to upsize too as the variation is ~3.25% between both.”

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.
