- Tendency to 'grease up' or lose optimal grip after prolonged hard driving
- Not the fastest option in its category for pure lap times
Tire B Potenza RE 71RS
Pros
- Outstanding dry grip and rapid warm-up characteristics.
- Highly predictable and communicative at the limit, allowing for easy recovery.
- Improved on-road refinement, noise levels, and comfort compared to its predecessor.
Cons

Tire A
Dunlop Direzza ZIII
We haven't collected enough community discussion about this tire yet.
Tire B
Positive
Bridgestone Potenza RE 71RS
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.

“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?”

“When I said 'they are more different than I expected,' the best way to describe that with one word is SMOOTH! These tires are smooth in all aspects. They are substantially quieter than the old 71R, maybe a 2 out of 10. After driving on two lane blacktops, I have not noticed any measurable gravel or other debris picked up at this point, definitely less than the 71R, maybe 50% reduction. Handling is the most important aspect for me personally and Bridgestone has hit a home run! Stopping fantastic and according to Bridgestone they are better on wet roads, IDK as I try to avoid driving in the rain. Steering is amazing and more sensitive! There is even a level of comfort that I did not expect for performance tires. Honestly, I am unable to come up with any negative. Five Stars! The post by jst2878 was spot on about them being a 'gift!' After break in greater than 300 miles, they just need to be hammered! After doing so yesterday, I have returned home for Pina Coladas & Pool this weekend!”

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.
