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.

“When I bought my freshly imported 2014 Nissan Leaf in Sept 2020 it had 27,xxx km on the odometer and a full set of Michelin Primacy 4 that were sidewall dated from very late 2018, so likely only very low mileage on them. I put another 47,000km on them before replacing with a full set of Toyo Proxes C100 Plus in April 2024 which have also been great. The Michelin fronts were certainly very worn particularly the shoulders. I really rate Toyos so would encourage you to have a look. I’ve since put 21,000km on the Toyos and even after 12,500km, in May 2025 at their most recent WOF, the fronts still measured at 7mm and rears 8mm. P.S I paid $900 total for the 4 x Toyos inc. fitting, disposal etc.”

“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”

“Am at Saifees, Mumbai. One of my Primacy 4 got punctured at an angle, so is wasted. The tread depth on these 4 year old, 41350 km run is just less than 4mm, so due for replacement after another 5-10k (3mm depth). Saifee tells me Primacy 5 may come at year end. Some tyres willl be manufactured in India (unconfirmed, but usually Saifee knows better) , but can't predict which ones. Meanwhile I've taken an Apollo Alnac in very good condition for Rs.1500/- and will change all tyres together to Primacy 5.”

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.
