Best test result: #1 of 4 in 2022 TireRack Extreme Performance Summer Tire Test R17 (wet handling)
“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”

Tire B
Positive
Bridgestone Potenza RE 71RS
The Bridgestone Potenza RE-71RS is widely praised by the community as an exceptionally sticky and high-performing 200 treadwear tire, popular for track use and spirited driving. Users frequently discuss fitment considerations like whether they run wide compared to other tires, and note opportunities for closeout deals. While recognized for incredible grip, users acknowledge their short lifespan and limited utility in cold or wet conditions.

“Mileage-expectancy of Bridgestone Potenza RE-71Rs? (200-rated, I think?) Forgive me I'm getting the terminology wrong, but I just bought a super dynamite NA Miata that has had a TON of incredible suspension work (mostly Flyin' Miata stuff) and the stickiest tires I have ever experienced by FAR: Potenza RE-71Rs. (Forget full measurements but they're on 15 x 7.5" inch wheels, 6UL's by 949 Racing.) And I think their life is pretty much over. I love them but I don't want to track the car; I want to drive it two hours into the country every other weekend. I want to drive through the mountains with great . . . spiritedness . . . but I don't need track-focused tires. I'd much rather have something slightly less grippy in exchange for longer tread life. The previous owner (who I've stayed in touch with) recommenced I get "300-rated" tires instead of "200-rated" tires. I don't really know what that means or how many miles I can expect from such a tire. I'm contemplating getting the Continental Extreme Contacts, but I just don't know enough about tires to know what they're like or how much ACTUAL mileage I can get----I also dont' understand 200 vs. 300 tires. Please help?”

“Track tire fitment Just got some new Bridgestone Potenza RE-71rs in 245/40r18. I did my research on this subreddit and it seems like that will fit without rubbing/camber bolts. Does anyone know if the RE-71rs’ run wide cause they measure a full inch wider than the stock PS4s’, I’m just wondering now if I’ll need camber bolts. I’d prefer not, just want to throw them on and go. For reference they are being mounted onto a 18x8.5 +45 Enkei TS-V wheel. If anyone could offer insight cause I just can’t understand how they would fit but maybe I’m just over thinking it. Stock suspension by the way. I searched the sub and didn’t see anything with exact matching specs, only bigger and different tires. Tl;dr Will 245/40r18 Bridgestone Potenza RE-71rs’ fit on an 18x8.5 +45 wheel without clearance issues/adding other modifications (camber bolts) on our car? Thanks for any help! Read more”

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.
Community buzz from Reddit and forums is shown for context only — it never changes the score.
