“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.”

“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.”

“Had a shop install two new Michelin Primacy 4 in the front of my W124 yesterday. On the way back home i checked the pressure and the right one was a little on the low side. Drove the car today and after a few kms of city driving i noticed it was steering itself to the right once i was out of the stop and go traffic. Got out of the car and the tire was almost flat. I put 2.7 bar in it at the first station but noticed the sidewall is now damaged and there's a buldge... How is this possible? It is wet and i can hear the sound of air coming out of the tire but can't identify where it comes from. If the rim is the problem, why did they install the tire without noticing me first? If they don't admit their fault and blame it on the rim, i'm going to have to buy a new tire...”

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.
