The Pilot Sport PS2 ZP (Zero Pressure) is Michelin’s Max Performance Summer run-flat tire developed for selected performance sedans and sports cars. Initially introduced as Original Equipment (O.E.) on BMW 3 series sport package cars, the Pilot Sport PS2 ZP has recently expanded its O.E. applications to include Michelin’s first Corvette fitment on the highest performing production supercar in Chevrolet’s history, the 2009 Corvette ZR1. The Pilot Sport PS2 ZP is designed to combine world class dry road traction, handling and cornering, however it is not intended to be driven in near-freezing temperatures, through snow or on ice.
The Pilot Sport PS2 ZP molds an advanced tread rubber compound into an asymmetric tread design featuring Michelin’s Variable Contact Patch to keep more tread rubber on the road during a variety of maneuvers. The tread design features large outboard shoulder blocks and continuous intermediate and center ribs to provide a solid connection to the ground for control during cornering, braking and acceleration in dry conditions. The tread design also features wide circumferential grooves and lateral notches that help channel water through the footprint to enhance wet road traction. The tire’s internal structure includes two steel cord belts that are further reinforced by size-optimized, spirally wound polyamide to improve steering response and resistance to distortion while enhancing ride quality and high-speed durability. Pilot Sport PS2 ZP tires incorporate Michelin’s newest generation of run-flat technology including a heavy-duty rayon casing reinforced by rubber zero pressure sidewall inserts.

Founder at Tiresout. Used to be working as an engineer at Bridgestone Tires Akron Technical Center. The responsibilities included but were not limited to technical computing, indoor & outdoor testing of new tires.
I highly recommend these tires. Great performance in dry, acceptable in rain. Reviewing this set as I order replacements. 4 years in service on the fronts, about 43k miles. Combo city/highway driving, including one cross-country round trip and a track day.Pros: very good performance, excellent tread life. Security and durability of run-flats. Precise and predictable handling, including spirited driving on windy mountain roads. Very little squealing even near performance limits. Quieter than competitors during first half of tire life. Run-flat worked fine for 40 miles on a trip thru mountains after picking up a screw.Cons: rear tires developed a droning noise after about 20k miles. Fronts got a little noisy too at about 40k near end of tread life.Overall weaknesses shared with any low-profile run-flat: Stiff ride, noisy over bumps, less comfortable than non-runflat equivalents, more expensive. As long as you are OK with these trade-offs, these Michelins are a great choice for high performance and reliability.
I highly recommend these tires. Great performance in dry, acceptable in rain. Reviewing this set as I order replacements. 3.5 years in service on the rears, about 40k miles. Still a little tread left (could get 43k-45k) but replacing now as a set since fronts are worn out. Combo city/highway driving, including one cross-country round trip and a track day.Pros: very good performance, excellent tread life. Security and durability of run-flats.

Run-flat worked fine for 40 miles on a trip thru mountains after picking up a screw.Cons: rear tires developed a droning noise after about 20k miles. Noise noticeable starting at about 45mph, then progressively louder til roughly equal to engine noise at 65+mph. Rebalancing didn’t help.

Have owned my BMW since 2013, when I bought it as a CPO (coming off someone else’s 3 year lease). It had Bridgestone Potenzas (OEM, RFT’s) on it, and about 5-6 months after I got the car, the tires were in need of replacement. Since I didn’t have much history with the car, I replaced the tires with the same Potenzas. Last month, it came time to replace the Bridgestones, and after having lived with RFT’s, I wanted to see if something else performed and rode differently.I decided to try the Michelin Pilot Sport PS2 ZP’s, and had them installed this past week. It probably wasn’t ideal that a major thunderstorm broke in Florida as I was picking up my car, so I drove home in torrential rain. However, despite the newness of the tires, they felt in control despite the several inches of water on the streets.I’ve only driven on the tires for about 3-4 days, but I can already tell a significant different in overall noise, comfort, and feedback, compared to the Potenzas. I didn’t buy my car to be pampered on the road, but these tires transmit far less road noise, they absorb city bumps and street construction far better, and also fight me much less on uneven paving. The difference was so significant I felt I needed to write a review sooner rather than later.Clearly, time will tell on whether they perform well once I’ve finished breaking them in. We are just about to start the rainy season here in Florida, and security on the road will be an important part of my long term pleasure or displeasure with these tires. I do occasionally break free with the car, so we’ll see how they perform in more spirited situations.
I was on the fence between going back with the OEM Bridgestone run flats and Michelin Pilot Super Sport non-run flats. After talking to other owners and Tire Rack reps, I decided to stick with run flats for the sharp steering response. I was pleasantly surprised that these Michelin run flats were available in the staggered tire sizes for my 2011 BMW E90 335i. The Tire Rack video comparison of these tires vs. Bridgestone OEM tires and others firmed up my decision to buy. My first impression is that the Michelins handle better, have better steering response, less noise, and better ride. The treadwear rating is 50% better than the Bridgestones I had, so I expect better life. I don’t drive the car in the rain if I don’t have to, as I have an old pickup for bad weather, so I don’t have any feedback to give on hydroplaning or wet weather traction. I will say that I’ve never had a bad Michelin tire in over 40 years of driving and so far these are carrying on the tradition.
I replaced the original Potenzas RE050 with PS2s and the comfort level was amazingly better. Not only that, but the noise level was equivalent of a all season tire. Very impressive. The let down was the handling and responsiveness of these tires. The tire walls are too flexible and my Z4 became wobbly when cornering and shifting vehicle direction fast (road or highway). It felt “spongy” to me. To that degree, it ruined the extremely sharp handling that my Z4 has. But overal the noise, comfort and grip are still superior than the original Potenzas.
If you are driving the smoothest roads on earth and only the smoothest roads on earth then these tires will work great for you. On the other hand if you drive into a city , ever, these tires are not for you. Blown out two in less than four months. Michelin dosent have an email listed on their website, however you can hop in your time machine and write them a letter, put a stamp on it and leave it in a mail box …… letting them know the durability of these $300+ tires is total garbage. I read reviews like this and thought ” it can’t be that bad” . It is . Save your cash and buy something else . Period.
It is my Wife’s car. However I race AutoX twice a month in Southern Louisiana. [Very wet and hot.] The tires held up extremely well this season with 2 drivers [a retired pro racer and myself] accumulative of 20 races this year. Excellent handling on wet roads and track. I am replacing them with the same for next season. The stiffer sidewall lends to rail like corners that seldom slide until well worn. Without the harsher wear of the autoX driving estimate a realistic 24 – 28 K miles in normal use. Noise level very low. Great tire for my needs.
