I first owned the Michelin Pilot Sport AS3, then my tires wore down, so went to the Michelin Pilot Sport AS3+. Now I'm currently using the Michelin Pilot Sport AS4. From my very early and initial impression (under 50 miles), these tires are the best of the group thus far. I found the AS3 and AS3+ were almost identical in tread pattern, driving, comfort with a slightly higher noise level. The AS4 feels like a significant upgrade. Firstly its an entirely new tread pattern from the past 2 models. A variation of sipe thickness and patterns. It looks like it will grip better. Briefly driving on both dry and wet roads, highway and city, it delivered nicely. It already felt great with the AS3 and AS3+, so I'd expect the same with some refinement. Personally, where I really found an improvement is the noise and comfort level. This is deemed an ultra-high performance tire. Its sporty, athletic and low profile. The handing is expected to be superb and usually the tradeoff is comfort and noise. I don't know how Michelin did it, but I've found the noise level lower and the comfort level higher. It rides much more smooth and soft with less tire noise than the AS3+. My car handles even better and I feel confident with my rear wheel ride. The only concern I have is longevity and durability. Both AS3 and AS3+ were sticky tires, so they wore down quicker and sustained nail damage. I'm expecting the same with the AS4 as I believe the tire compound is the same or similar to the previous 2 models. Plus in the end, compromises are always a result of changes. I hope I'm wrong, but time will tell. Its already a superior tire and I've had a nice history of use. Michelin, if you could make a tire with added durability (less chance of nail, staple, debris causing tire damage), you'll have a true legend! In the meantime, well done on the AS4.

I've got a 2009 Jaguar XKR Portfolio Convertible with 69k miles. This is my third set of tires. My first were Yokohama's....not a bad tire but in my opinion, they don't compare with the Michelin Pilot Sport AS4. I'm on my second full set of 4 Pilot Sports. When these wear out, I'll buy another! They handle extremely well, the ride is wonderful and they lasted about 45,000 before needing to replace. I'd absolutely recommend these for your sports car!

Came on new 24 Porsche Panamera 4. Total of 4,600 miles to date. Great handling and good in the rain. Works well on light snow too. Tires are different size front and rear so cannot rotate. Time will tell how long these will last. I would be happy to get 30k miles.

Terrible quality control. Michelin supplied 2 additional replacement sets and all 3 sets produced a vibration. Tires seen bouncing on the balancer and unacceptably high road force. 26lbs is WAY too much tolerance!!! 10 lbs is felt on low profile tires. No longer a market leader in quality.

I purchased a set for a our BMW approximately a month ago looking for a set of all season performance tires which we could also use in light snow but enjoy during spirited drives in the summer without the hassle and expense of 2 sets of wheels/tires.

Significantly louder than the HX MXM4's they replaced. Noise starts right at 40mph and gets significantly louder at highway speeds. Likely going to swap them out for another brand as this is the only Michelin tire that fits 245/50/R17. Tire handles great but I just can't deal with the noise.

I bought these for my charger scat pack. In a month they had 2 separations on the inside bead of the tire. First there was a vibration this is when we discovered the defect. Huge safety issue!! Then we replaced them. 4k miles another vibration and it was all 4 tires split on the inside of every tire. This could have caused a crash or even death for myself and my family!! Do Not buy!!!

I brought my 2007 Mercedes Benz CLK 350 in for service inspection as the "brake pad wear" light came on recently. During the inspection, I was informed that the rear tires on the vehicle needed to be replaced. All four of the tires on the vehicle are Michelin Pilot Sport AS 4 B 225/45ZR17 94Y XL Michelin Pilot Sport AS 4 B 245/40ZR17 95Y XL Michelin Pilot Sport AS 4 B I was shocked by the news that these Michelin tires needed to be replaced, given that the vehicle is driven less than 4,000 miles a year, and the vehicle is almost never driven on the freeway, and is rarely driven above 35 mph on surface streets. I have now confirmed that these Michelin tires were installed by Big O Tires on December 7, 2020, at which time the mileage on the vehicle was 90,415. The December 7, 2020 invoice from Big O Tires states that these tires come with a warranty ("Minimum Mileage Warranty: MFG45"). This past week, on Monday, May 12, 2025, the odometer mileage was recorded as 105,606. Assuming these odometer readings are accurate (which they appear to be), this means the vehicle has been driven a total of only 15,191 miles in the 53 months since these Michelin tires were both recommended and installed on the vehicle in December, 2020. This is under 3,500 miles per year. I have never heard of tires lasting only 15,000 miles, and I certainly did not expect this of a supposed "quality tire" bearing the Michelin brand. Honestly, I thought that I was buying the best possible tires for this vehicle - and, in any event, these were the tires that were recommended by Big O Tires. During my second trip to Big O Tires on Monday, May 12, 2025, I asked about whether these tires came with a warranty, or whether the dealership (Big O Tires) or the manufacturer (Michelin) would stand behind the tires and admit the obvious - that these tires are not supposed to wear out within 15,000 miles of ordinary driving. In my discussions with Big O Tires on Monday, May 12, 2025, I was given the clear impression that there was nothing that could be done for me at the dealership (Big O Tires), and that I was free to take the matter up with the manufacturer (Michelin). This seems strange to me, since these tires were recommended and installed under a warranty by the dealership (Big O Tires), and it is the dealership that promotes the Michelin tire brand. I have now done some basic research on the internet, and it seems that many other customers have complained about these tires wearing out prematurely. The loudest complaints seem to be from customers who likewise cannot believe that Michelin tires would last as little as 15,000 miles. Conclusion The more I consider what has transpired, it is unlikely that I would rely on Big O Tires or the Michelin brand in the future, or recommend them to others.

BMW M235 My previous tires were Pilot Super Sports which I found to be fabulous in traction, ride and response. But, living in the snow belt, the lower temperature season can really shorten the time I have them on the car. So when I needed a replacement I thought why not go with the AS4 , maybe loose a little performance but enjoy a longer time with no snow tires on. I've now driven about 600 miles with them. I find them as harsh and uncomfortable as the RFTs that were OE on the vehicle. Jarring really even on the softest suspension setting. Further my dealer could not balance them for a smooth ride after 3 tries on the Hunter Road Force. I will say that after the break in, they had good traction in dry and wet. Never got to snow. I'm calling uncle and swapping them out for another brand.

The specs and real performance of these tires are incredible. 255/35R21/XL 98W Front - 275/35R21/XL 103W Rear. I know My Tesla MYP can outperform 97% of the vehicles on the road. The car can do 0-60 in 3.4 seconds. Most likely your non-Tesla car cannot. I put it to the test on my daily 55 mile commute. The tires have a lot to do with this. The heavy EV and high speed rating are brilliant technology. Fully confident all weather rain/sleet /snow/ice at very high speeds. Hey Michelin Bring back Premium Touch.. love it
