Tire A
Continental UltraContact UC6
We haven't collected enough community discussion about this tire yet.
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.

“Yokohama es la que va pero fijate que ya este año salieron las nuevas advan v61, esas geolandar g058 son modelo viejo. Las primacy 4 son modelo viejo y te las cobran como si fuesen oro. Bridgestone y continental tambien las vi a precio de oro. Pirelli son medio pelo, no son malas pero son ruidosas, ya que estás en el baile podes ir por algo mejor, como las yokohama.”

“I'll have to remember to get some E's. That aside, the primacy 4 fitted to the mokka only have 6.5 mm, if that, from new so perhaps they were just an older name. Gaz”

“Both our Polestar2 (new) and 2016 Leaf (Jap import) arrived with Primacy 4s on them. The FWD Polestar needed fronts replaced at ~35k km and being 245/45 R19s Primacy were too pricey so went with Kumho Ecsta PS71 equivalents for a lot cheaper and negligible difference in performance. The rears on the Polestar are still going strong at 45k km and look like at least 60k km will be likely. We also fitted Kumhos on our previous Leaf and were very satisfied with performance and life.”

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.
