Higher is better. The Relative Score follows your weights below; category scores do not change.
Wet grip starts at “Important”. Treadwear starts at “Neutral” here: road tests measured it for at most one of the two tires, so it rests on owner reviews. Move the sliders and the scores update instantly.
Only one of the two tires has a score here, so this weight changes nothing in the head-to-head.

Community discussions around the Bridgestone Turanza T001 largely center on replacement decisions, tire longevity, and tread aging. Users note that the tire provides a good balance of comfort, durability, and low road noise compared to sportier alternatives, though owners frequently question surface cracking after four years of use.
“Just got a new set of tyres - Bridgestone Turanza T001 215/60/R16 at 77k kms.”

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.
“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”
“I have used Michelin tires before but recently I already have used Nankang tires. I compared Michelin and Nankang tires after testing. It was quite a pleasant surprise that the Nankang AS1 was nearly on par with the Michelin Primacy 4 in braking distance. Both tires performed exceptionally well, with the Primacy 4 only stopping slightly 3 meters shorter than the AS1.”
“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.”

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.
