“New tyres. Michelin Primacy 5. My Mazda 6 had factory original Bridgestone Turanza 001’s fitted when I bought it. They had 4mm left but were really slippy in the rain and loud as heck. I really liked Primacy 4’s in my previous car (Saab 9-3) and decided to go with the Michelin again. So far my feeling is really positive. They are smooth and silent and bumps on the road feel less sharp. Michelins usually need to be run in a bit so let’s see how they feel after 1000 km. Read more”

Tire A
Toyo Proxes ST III
We haven't collected enough community discussion about this tire yet.
Tire B
Positive
Michelin Primacy 5
Community sentiment towards the Michelin Primacy 5 is broadly positive, with users frequently praising its low road noise, comfort, and noticeable improvements over factory tires and prior models. However, opinions are mixed regarding ride firmness on certain setups, and several drivers report unexpectedly rapid tread wear and mediocre wet grip under aggressive acceleration. Comparative discussions frequently position it against the Continental PremiumContact 7 and Michelin Pilot Sport 5, framing the Primacy 5 as an efficiency- and comfort-focused touring option.

“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.”

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.
