The free installation and lifetime balance/rotation was a fantastic value-add to the already good value of the tires themselves. By the time I dropped my car off, drove across town to my favorite diner for breakfast, and stuck a fork in my eggs, I was getting a notification that they had finished installing and balancing my new tires.

Great riding tires.

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.

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.

We put these tires on our BMW 328i not long after we purchased the car to replace the awful run-flats. It was an amazing difference in ride and noise level. Our 2020 Honda Accord 2.0 Touring was purchased from a friend in 2022 that had the standard 19 inch wheels. They may be great for performance but they rode like a wagon and were prone to curb rash. We're pretty conservative drivers. Based on our BMW experience, we switched to 17 inch wheels (which seems to be fairly common) and also purchased the Pilot Sport tires for the Honda. The ride quality improved drastically for the better.

Very durable tire with great handling and responsiveness in all weather. I have put these tires on multiple vehicles that I have owned (Toyota Camry, BMW X6, Audi A6, Lexus GS300) over the years and they’ve exceeded the 45K warranty every time. They have excellent traction especially is wet weather conditions greatly minimizing hydroplaning instances.

Michelin pilot sport as 4, tires are amazing. Extremely smooth ride, quiet tire. Very happy. Went with 255/40/17 on front 285/35/18 rear since the OE 265/40/17 front and 295/35/18 was not available. Fits perfectly on factory c5 zo6 wheels. 100% satisfied!

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!!!!

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
