Tire B
Positive
Michelin Primacy 4
The Michelin Primacy 4 is generally praised for its comfortable ride, low road noise, and strong braking and safety in both dry and wet conditions. While many users report excellent tread longevity across tens of thousands of kilometers, some note faster wear on heavier electric vehicles or rough surfaces. It is viewed as a premium touring tire that is unsuitable for winter conditions, prompting some drivers to weigh its high price against newer models like the Primacy 5 or cheaper alternatives.

“I have on my BMW E87 118d Primacy 4 since 2020 and I think I have covered about 30k km with them and I can certainly cover another 5-10k km with them but the DOT is 2019 so I am changing them next year. I thought I would buy new ones this year, but I gave up because I will soon put on winter ones, so I will buy new summer ones next year. I am delighted with the Primacy 4, excellent and safe in the rain and in the dry, especially in the rain, I literally drive as if it were dry, that's how safe I feel, and I honestly drive a little faster and more aggressively. It is 205 55 R16 and the tires are made in Spain.”

“Michelin Primacy 4 in Snow Alright, I have some pretty fresh Primacy 4 tires that came on my 2022. I live in Minnesota and don't commute much in winter but do make some shorter trips in a metro area. What is the likelihood that I'm going to want/need different tires for winter? I thought about getting a set of Crossclimate tires and just using them year round but it seems like such a waste to not use up these nice Primacy 4 tires. It probably won't be very cost effective to un-mount and mount every year. Let me have it. Read more”

“Michelin Primacy 4 or Conti UC6 - Virtus GT Hey, i recently got a Virtus GT with stock Apollo alnac 4g tyres - looking to upgrade them. As per ChatGPT my options are Michelin Primacy 4 and Continental UC6 - budget is not really a problem. Overall i want good grip, handling, comfort and low cabin noise. Not going for Pilot Sport 4, because don't want to compromise on comfort for performance when i am not going to push my car too much, hence PS4 is a no no. But read it somewhere that with Primacy 4, there is a noticeable difference in mileage not sure if it means going up or down. Need recommendations on what i should get! Thanks in advance”

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.
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.
