I was not told or read anything about this tire for my Corvette Grand Sport being a run flat tire. I found out from the dealer a few days after having the tires installed when I returned to have to lug nuts checked for exact tightness. The tire is very noisy and a hard ride.

These are by far the worst “all season” tires I have ever had. In 1 years time I have needed to plug or patch all 4 tires, including plugging 1 tire twice. They grip the road great, but the problem with that is that they grip every nail and other pieces of debris what seems like 100% of the time. I say other debris because one of the plugs I needed to apply was because of a relatively sharp piece of plastic, and another was because of a broken VW emblem that I ran over. All other incidents were because of 2 drywall nails (tiny) and 1 normal screw that I would expect to puncture any tire. My driving habits have not changed and I do not live near any new construction locations. I have never experienced a more sensitive tire, and I am 37 and have driven foreign cars with ridiculous speculation tires for much of my adult life. Stick with the other trusted brands. These are performance tires, and if you are looking for tires to use on a track, then maybe these are the ones for you. If you plan on using them for everyday driving then I caution you to stay away!!!!

The experience of my first two installed Michelin Pilot AS 4's on my vehicle prompted the second purchase of the other two to complete the set. I replaced my tires with these on my vehicle because of the Michelin tradition for tires along with the performance and quietness they bring.

Clued to the road, quiet and responsive absolutely the perfect tire for my Jag

These tires are outstanding. From road feel to traction and handling they have exceeded my expectations. For street tires I don't think you can do better. The 40F limit of temp is something to consider if you are driving in the mountains.

I'm extremely disappointed with the durability of my Michelin tires. I purchased them just about a month ago, expecting the quality and reliability the brand is known for. Unfortunately, after a very normal driving experience, one of my tires already has noticeable sidewall damage. This was not due to reckless driving, but from a common road condition that any tire should reasonably withstand. For a premium-priced tire, I expected much better durability and resilience. It's frustrating to invest in a trusted brand only to experience damage so quickly after purchase. Tires are supposed to provide safety and peace of mind, and right now, I'm feeling the opposite. I am hoping Michelin will stand behind their product and consider a replacement or some form of support, as this experience does not reflect the quality I believed I was paying for.

Tire performs well. Tires are on BMW 330Ci. Have tried a few other brands. Would normally achieve half (20 to 24k) of recommended tread life. These Pilot Sport AS4 tires have provided the longest durability achieving 40k of tread life. Plus, they handle well and provide a great driving experience.

Absolutely disappointing product and quality . Bought a car that came with these underperforming overpriced tires that were installed at 12,500 miles on an audi s5 at just 22,500 miles 2 of these tires blew up on me on the road as i was driving 35mph and the other 2 they're already down to about 5/32 thread life i hear these are warranted until 45k miles but ill be lucky to get 7k miles out of the two that are left honestly will never be purchasing from this brand as they like to mark up their prices based on their brand prestige but they really fall short of what they are giving their customers. I would honestly recommend to people considering buying this tire to go with a cheaper alternative like a yokohama or continental as they arent perfect either but atleast you wont break your wallet by overpaying for a tire that can easily explode and wear out like the michellin ps4 ‘s . Never again will i use Michelin products not even for free i honestly don't see the justification for the price of this tire especially since lots of customers constantly report that these

I bought the Michelin Pilot Sport All Season 4 (ZR rated) for my Lexus LS. These tires are SO NOISY!! They are also hard and you feel the shock from rough roads. They are much noisier than my old Michelin tires. However, they are much better than the Michelin Primacy mxm4 A/s which I swapped for the Pilot Sport. AVOID, AVOID, AVOID both the Primacy mxm4 and Pilot Sport. Being EV ready, they are low rolling resistance, hard rubber and LOUD. They do not perform anything like the Pilot Sports of 5-10 years ago, which were stellar tires. I am very, very disappointed. MICHELIN SHOULD HAVE SEPARATE LINES FOR EV AND EFFICIENCY AND OTHER LOW CLASS CARS, AND A DIFFERENT LINE FOR PEOPLE WHO WANT THE WONDERFUL QUIETER, SOFTER AND SMOOTHER TIRES UPON WHICH MICHELIN BUILT ITS PRIOR REPUTION. One positive: it is good that Michelin has its 60 day swap program. Given the poor quality and NOISE of these new Michelin kinds of tires (all of which are designated by Michein as EV Ready), I will probably move to a cheaper tire mfgr whose tires are grippier and not as LOUD and save the money.

Excellent tire. The compound is sticky and aggressive while still offering good traction in cold weather. The tires appear to be well made with a very still XL-rated sidewall. Handling is extremely precise and predictable with perfectly controlled behavior when approaching the limits of cornering grip. The tires are very comfortable and pretty quiet for a performance A/S tire. While I cannot comment on tread life or highway stability just yet, no doubt those will meet expectations as well.
