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.

From Reddit, forums and review threads. Not part of our score
Community sentiment toward the Bridgestone Potenza RE-71RS is overwhelmingly positive, with drivers praising its high grip levels, responsive turn-in, and improved refinement over the older RE-71R. Discussions frequently center around track and autocross setups, optimal hot tire pressures, clearance pricing, and its streetability regarding road noise and gravel pickup. Minor caveats noted include fast wear characteristic of 200tw competition tires and rotation limits stemming from an asymmetrical tread design.
“Need heat cycle advice I recently got a screaming deal on some Bridgestone Potenza RE-71RS for my daily driver. It usually doesn't see track time but I figured it would be fun to try it out for the cost. The tires were cheap because they had a 2021 production date. In the past to heat cycle a tire, I've just driven on the highway a couple of hours and let the tire sit for 24 hours. The hurdle is, It's winter and too cold to really make an impact. To add to that, I doubt I will have clean enough roads for that tire. My track does have winter lapping when it is clean and dry, but it still may be cold. Any suggestions on how to get a heat cycle on these tires in cold temperatures? Read more”
“I just put some Bridgestone Potenza Re71rs on my FC1 and holt shit these things kick ass. I took the same turn series before/after the tire change and the turn-in is ridiculous. Looking forward to hitting up some backroads and Lagun Seca for a trackday.”
“Quote: Back to the RE71RS tires: 1. How loud is the tread noise? 2. How much gravel are they picking up in normal and back roads driving? Just replaced my 7 and 8 year old Bridgestone S04 tires (aged out). Less than 100 miles so far. I'm happy. 1. No increase in tread noise I can detect. Surprisingly quiet. My former RE-11As were a little noisey. The Dunlops were LOUD. 2. Twinkling of fine gravel is present under the car. Noticeable and expected. -- Chuck”

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.
