Bridgestone Potenza S001 

I agree with most of the reviews, this is an excellent tire in dry and wet, I just drove through an absolute summer downpour here at highway speeds and felt fully confident, and the traction around roundabouts and on-ramps is excellent. Note I have the Eibach pro-kit springs on my grand touring (absolutely necessary if you are still on stock springs...those are way too soft). BUT, I haven't seen mention of the effect of temperature, and these really change when the temperature drops, so I thought I would comment. I know they are summer tires, and this might not matter if you are in a warmer climate, but these things really do lose grip in the cold. In the 40's there is a noticeable loss of wet grip, and in the 30's and below it's like driving on hockey pucks even on dry roads. I have slipped the back out on dry pavement just making a normal left turn from a stoplight in the 20's F. I never drive my MX5 in the snow or salt as I have another car with snow tires for that, but I try not to even drive it when it's dry when below 40 because of the loss of confidence. Planning on getting all seasons next (have really liked Michelin Pilot A/S 3+, great in everything except snow/ice), something that will let me drive safely year-round. Just something to think about if you're somewhere it gets cold and don't need/want a separate set of snow tires.

In Italy only S001 is available and not S04PP. My car has and ECU mapping and a TarOx B33 10 pots calipers and 335mm discs system on front and 315mm discs on rear. With Carbon Lorraine RC8 pads on front and RC6 on rear. With such a braking setup and 175Bhp under the bonnet with loads of torque, it is easy to detect tires' performances on such a light car. Former tires were the Pirelli PZero Rosso, always 225/40 ZR 18 92Y XL. Pressure was 2.5bar front and 2.4 rear for both brands. The PZero ended their bed in period after 2000km and the Bridgestone are still to bed in at the rear. Makes sense given the higher treadwear index of Bridge tires.
Performancewise the Rosso proved to be quite more responsive, requiring noticeably less steering angles at same reference turning angles, hugely more responsive in slow speed (less than 50km/h) turnings and slalom like turnings. I can witness more braking performance on Rosso when dry: they keep the grip even from 180km/h to nil, while S001 are till now worse performers.
Where S001 excel is on wet roads.Very good acquaplaning performances, very good cornering. Braking on wet is another story, but it is common to many max performance asymmetrical tyres, and must be considered the fairly aggressive braking system my car is equipped with as well. In the end S001 COULD potentially be quite top notch tires but they suffer from heavy understeer: initially they quickly respond to driver's input, yet quickly going into understeer mode. Till now nearly always I had to correct steering angle at 1/3 of the curve being careful not to lift right foot at the same time to avoid unwilled understeer to oversteer transitions. Ultimate grip when cornered is impressive and superior to PZero Rosso, yet shoulders should definitely be stiffed for confidence inspiring crisp turning.
Will see if mileage will improve their score.

I use this tire for track days as well as general highway driving. 1st track day in the wet had low time with Cayman R on Hoosier rains next best. Incredible traction at full throttle 2nd gear exiting corners. I run dyno 485hp with this car so was very pleased. Goodyear F1's were garbage in these conditions. Did notice slight delay in quick turn in response. Slowed down the rapid wheel action and was actually better at exiting. Tires do not hydroplane or hunt on Washingtions horrible highways. Highly recommend this tire. Who cares if I wear them out from driving fast. Just get another set.

I was excited to test these tires out that came on my car OEM. They are great in the dry on b roads. Great steering response, and handling. High traction limit, but don't expect any tire squeal at the limit. They just break traction with no indication, but they can be quickly regain control. These tires are terrible in wet conditions. With standing water on the road, hang on they will hydroplane. They made me dread driving in wet conditions. They also crash over expansion joints, slight bumps, cracks, small pot holes. They wear out fast also, don't expect more than 20,000 miles on a set at the most. After driving over the summer, I was very disappointed. I won't be buying these again. Just FYI if you are in the market for summer tires. You have been warned.

OEM tire. I think they are better than reviewed. Very good wet, great dry. A bit noisy but what do you expect. Feel very confident in the rain and around corners. I push the car pretty hard and I have not had any (unintended) wheel slip. I will not be having these on in sub 50 degree weather. Will swap to Michelin PSAS4’s. But will probably put these back on for the summers.

These were the factory tires on my 2016 370Z Nismo which I purchased with 3800 miles on it. I seems like my experience is an outlier, but my first track day on these tires was very disappointing. The morning was cold (40's) warming up in the afternoon to low 60's, but I found myself struggling to get grip most of the day. I previously ran Bridgestone RE-760s and RE-11s on my 2010 370 Z Coupe and got much better performance; especially with the RE-11s. This is also my daily driver and while I don't have enough experience with them in the rain, I have been satisfied with the dry performance. My next set will definitely be RE-11s.

I was relatively happy with these tires coming with the 2016 MX-5 Club, but they leave a lot to be desired, especially considering the price point and tread life. On dry pavement, they handle quite well and are predictable. The ride is quiet and comfortable for how sporty the tires are. I only drove on the road with these tires, and for the most part they were plenty fun for road conditions.

Where they are not very strong is when it's wet. I was on my second summer with plenty of tread driving in moderate rain, about 50mph on a big open highway, and they almost lost traction out of nowhere on a slight curve. There wasn't a ton of standing water or anything, this was where you'd easily see a random minivan going 60mph in worse conditions. Needless to say, I drove very conservatively in any rain after that. They were also very easy to break loose when it was the slightest bit wet. My winter tires, Pirelli Soto Zero 3, were almost better in every regard, outside of steering response and road noise which goes to be expected. I should be looking forward to when I can take off the winter tires and put on the summer tires, not the other way around..

I put maybe 10-15k miles on them and they were getting pretty low. I drive spirited, but I'm not constantly drag racing, braking hard, and carving up windy roads. The majority of time was commuting. They just aren't anything special for the low tread life, high price point, and underwhelming performance. They feel more like a good all season that's only really good at dry/warm weather.

I recently purchased a '16 Miata Club spec (5 months) and these tires came with it stock. I have 3300 miles on the tires with 2200 miles of highway (road trips), 2 autocross events, and 4 days of track events (HPDE).

Overall i am very pleased with these tires. They provided very good wet grip in heavy rain and communicated its levels of grip well enough to instill confidence. While driving, they provide low levels of road noise for a summer tire, and are not terribly rough over bumps.

At the track and autocross, I was also very pleased with the performance of this tire. I find the tire enabled very direct turn in with little instructional lag or slop. The tires broke traction with a progressive feel and an audible transition from singing to screaming. 2 autocross events and 2 track events were held at 50-75 degrees ambient temperatures and they held up well. 2 track events were held at 100-110 degrees ambient temperature. During the hot events the tires proceeded to wear faster than track focused summer tires, but not at an excessive rate.

Regarding durability, these tires resisted chunking, though they were soft enough to pick up rubber left on track. I am currently just above the tread indicators, though could reasonably have 1 event left on the tires.

I would recommend purchasing them again.

I traded from a 2010 Civic Si fitted with Conti Extreme Contact Sport DW tires in the stock size to a new 2018 MX-5 GT. The Bridgestones do not have the soft sidewall slop that the ECS tires did. This makes for a stiffer, firmer ride but also makes the car turn in more predictably and "surefooted".

Noise is better than the Contis, dry traction is less, and wet traction is noticeably less....I would say overall for a stock fitted tire it is a good option from factory. Given the Miata is prone to road noise and tire noise, for a daily driver this tire is good at balancing performance with comfort. The ECS tires with the large groove pattern gives off distinct road noise that would be harsh for a driver in a Miata.

I do not advise this tire for track/ autox use, and wear is average. With 5k I already notice wear and will rotate frequently to make them last.
