These were fitted after the OEM tire, a Michelin Primacy, and were wholly transformative for the communication, handling and limit behaviour of the FR-S (also Toyota 86, Suabru BRZ) chassis. The limit was higher, and the breakaway was transparent, smooth and controllable. In the dry, they were a massive improvement, but in the wet, even more so over OEM. The wet grip felt like 80% of the dry grip, meaning I had total confidence in anything but a giant, hydroplane-inducing puddle. Even if there was one side of the car in an unavoidable puddle at speed, I wasn't worried because the other side of the car had sufficient grip.
I did not use them in the snow or ice.
I am not a driver concerned about wear or tire life - I value handling feel and grip over comfort and life. I had no issues with either the comfort of the wear rate of the tires. After a particularly spirited drive, the shoulders would show signs of wear, but that would clean up after a week or so of sedate commuting.
The only complaint was that there was a minor delay (or lack of instant response) around center at highway speeds. But these are All Seasons, and the wet weather performance more than made up for that minor gripe. I recommend these to anyone who drives spiritedly, especially in locations that get lots of rain - like the Pacific Northwest and similar areas.

This is a follow-up review to the previous latest review of these tires on the Audi A6 quattro with 22-23k miles to add on things I failed to mention. I have recently switched to the CrossClimate2 due to end of life of the Michelin Pilot Sport All Season 4 with about 23k spirited miles.
-Dry Grip: I understeered more than I oversteered, in fact I never recall ever oversteering when quickly accelerating and turning or cornering at high speeds I would give a 9/10. Never had issues with braking, always stopped quickly when needed would give it an 8.5/10.
-Wet Grip: With fully wet roads pouring down rain, I always felt in control. Going around corners at high speeds 60+ mph, I felt the car lean into the corner and understeered through it no issues, 9/10. Wet and Dry performance was pretty similar for me in handling as well as braking, 9/10.
-Wear: Do not buy if you don't want to change out tires often, albeit it depends how much you drive of course. These lasted me 22k-23k miles, were very smooth, and were very loud, 3/10. Dry and wet traction did deteriorate, but not very drastic. I rotated tires every 5k miles and did alignments at 10k miles.
-Comfort: While I do not have too much of experience with different tires in comfort, these seemed alright enough. Not harsh ride, not loud.
-Snow Grip: Last snow season I had, about maybe 18k miles on the tire, it was adequate enough to get me to point a to b. I had a combination of oversteer and understeer, but primarily understeered more, the bad kind on fully covered roads with sometimes slush. When making 90 degree turns, I often understeered and kept going straight more than turning into the corner. I'm unable to turn off traction fully on my car which doesn't help sometimes, only 1 layer of TC of the 3. Sometimes it would oversteer when turning, which was actually more controllable than the understeer in more cases than not. Though, it was pretty predictable and took a little bit to regain traction at times. Going in straight lines, you will get pulled into the shoulder of the road if you're not careful. I can handle high speeds going straight in fully covered highway of light snow, about 60-70mph, your mileage will vary a lot though. Snow handling is about a 5/10 for me. Braking was fine, always practice earlier braking and give people enough space and you should be good, 6.5/10.
-Ice Grip: Finally, the only ice I was able to encounter was black ice. Braking was around a 5/10. Driving through it in a straight line on a highway around 50-60mph, it was a wavy ride, it wanted to slip out but didn't. I had confidence, however, that I would not slip out. Don't recommend it of course, I'm a crazy driver.

These tires have proven to be one of the best things I ever put on my car. I've had this Mazda 3 for many years and have kept its mechanical condition as close to perfect as possible, but the tire type has changed routinely depending on where I live and how I was doing financially - from cheap tires, to standard touring tires, studless snow tires, and these Pilot All Season tires. They are not the most comfortable tires nor the quietest, I'll say that - you'll get better and FAR quieter ride quality out of many other types of tire, but they also aren't inherently uncomfortable. The biggest annoyance factor you may take into consideration is the large amount of road noise.

The handling with these tires, however, is something I can only describe as magical - this may seem quite specific, but the initial turn-in when going around a curve, especially at speed, is considerably more responsive and provides you greater confidence than any other tire I've personally experienced. This also includes Pirelli's direct competitor, the P-Zero All Season. You feel absolutely everything in the road and have no trouble whatsoever determining your car's limits in more aggressive driving. Even in wet driving, that confidence largely remains intact - something I very much did not expect in a performance all season tire despite the 'all season' moniker.

Temperature plays a huge role however - when the outside air gets colder, the tires do not grip as well. Winter time here never fully reaches below freezing temperatures, but even so the tires would begin to noticeably feel less capable in low temps. These tires love heat and if your journeys are typically shorter, slower, or in colder climates, you may not be able to heat the tires properly to experience them as they should be felt. It can even reach the point of danger as I found out, as a project car I'm working on has some cheap budget tires on it and can come to a stop very quickly even in cold temperatures as the cheap all seasons on it do not require as much heat to effectively grip - meanwhile, the Pilots almost sent me into a car that decided to suddenly cross multiple lanes of traffic at slow speeds on a 50mph road when they could not grip during cold, dry weather braking.

The tires have also noticeably worn after around 10,000 miles. This hasn't affected their driving feel, but their specifications listing around a 40k+ mile tread life are flat out not true. I expect these to wear out and need replacement within another 10,000 miles or so, and the Pilots are quite pricey compared even to other similar tire types from competing brands. These tires should be seen as a treat for you as a driver and for your car - something that you will greatly enjoy, but not something you should expect to last a long time or be kind to your wallet.

Great tire for the rain. Lots of dry grip but steering feel isn't as good as a true summer tire, so that's the price you pay for a more mild tire like this. Not good in the snow or ice at all. I've seen some sources rate these as having decent grip in snowy conditions but that is definitely not my experience: These aren't a substitute for winter tires. Overall a great tire for Vancouver, BC, Canada.

Dry grip was great, I could often push the limits of my car with no issues. Wet grip seemed very similar to the dry grip. Tires had a little noise but it's not bad. The wear isn't that great, I have about 22k-23k miles on the tires and they look smooth. Probably 5k-10k miles left in them. Deep snow wasn't that great, took a minute for me to get out of a situation I purposefully put myself in, probably about 5in of snow. Light snow was better, I pushed my vehicle to the limits on the highway with a fully covered road, about 67mph. It wanted to slip out but my traction control didn't let it and kept straight the whole way. If you lose control like I purposefully did on a fully covered snow road, I was able to recover fine, took about 10s to with my car pointing about 2oclock left and right. For winter, I firmly recommend a better tire, like a winter tire. For every season, an all weather tire. I wouldn't buy these again due to the snow and abysmal treadlife.

Threw these on my 2018 c43 coupe today after reading reviews all week. I instantly set out to test the performance all evening after throwing them on and I couldn't stop smiling. These are perfect ‘AS’ tires if you love to have fun on a day to day basis while still maintaining it’s practicality. I chose these over summer tires because of how unpredictable the weather could be even during the warmer months here in Ontario. I‘ll still get proper winter tires when the time comes due to the amount of snow we get as well.

Currently running a stage 1, and I can now confidently put all that power down as intended lol. So far it’s left me thinking about how good the ps4s must really be as summer tires if the AS4 tires completely changed the feel of my car. It feels like I drive a ‘track car’ as a daily due to the feel of these tires lol

I live in Hawaii so the roads are in pretty good condition and I don't have to worry about ice and snow. I replaced the Goodyear Eagle GT (OEM's) on my car with the Michelin Pilot Sport AS4's about 3 months ago. What a difference in handling, road noise and comfort of the ride ! The tires feel "sticky" to the road with great handling in corners and on the twisty roads up into the mountains. I haven't noticed a significant difference between dry and wet grip, as the tires provide a consistent sense of confidence regardless of the weather conditions. I have noticed some mild road noise, but nothing as compared to the old Goodyear tires. I will leave an updated review in regards to tire wear, but so far I would say highly recommend!

my 2016 mustang gt came with Pirelli pzero nero tires. i'm the one guy on the mustang forums that likes these tires, however during the post-pandemic supply chain issues i could not find them. so i bought the Michelin Pilot Sport All Season 4 because they were the only "good" tire i could find. i found the pirelli and the michelin equal in everything except: dry road michelin are better, wear michelin are lasting me longer. i did get 0.4mpg more on the pirelli.
im in south texas so weather is hot. i have a 1 hour commute to work (24mi highway, 20mi city). road are generally good. im likely to get the michelin again as they have already lasted me 40% more than the pirelli and are still good.

I run my car in Vancouver, BC, CA. Typically winter involves a lot of rain, but snow will be a thing to deal with at least a few times a year. It is hilly (very much mountain adjacent), and when snow comes it tends to be very "greasy", and will not be cleared by the city. These tires are enough (when combined with a soft touch on the gas) to negotiate the snow we get here. They are even enough to give a strong sense of superiority to all the boobs who try to use summer tires, and lesser all seasons. They are EXCELLENT in the wet, which we really get much more of. Intellectually, I know I can get more in the summer out of a dedicated UHP, but in normal driving that is a point you won't likely reach on any regular basis.

Probably one of the best tires you can buy if you need some amount of snow and cold weather ability but still want excellent sporty performance. The dry/wet performance is about 80% of what you'd get with a summer tire, but you can run it in the shoulder seasons or in light winter weather. My main complaints are that the steering response isn't as good as the previous AS3+. The right quality is pretty average for an all season tire, but its OK. All around great options.

Easily my favorite tires I've ever owned. Living in the southern US, I use these as my daily driving and winter tires. It gets cold enough that I can't use track or summer tires year around, but doesn't snow enough to justify winter tires. I have a fair amount of experience with track tires, and on the street, the AS4 really isn't that far behind them. They wouldn't hold up to the same abuse, but that isn't their purpose. Since these are so good, I view the PS4S as being in the no-mans land for tires. One of the super 200 tw tires for summer and the AS4 for longer trips and winter is the magic combination for me.

Michelin "Total Performance" is right. This tire compliments the VW e-Golf perfectly. Using the 205/55R16 size with stock wheels, it strangely drives so neutral now that you could mistake it for a rear-wheel drive car. I've had a number of Miatas to compare it to. The control it gives at the limit in both a straight line and in the bends is absolutely confidence inspiring. In terms of mileage loss, it's negligible - somewhere between 2-5% range overall in my tests of frequent trips. I'm not surprised because Michelin lists it as low-rolling resistance tire for EVs. Any trade-offs over a purely eco-focused standard touring tire are overwhelming positive. If you can't tell, I'm thrilled with this tire. Does there exist anything better for its use case? Well, if this goes on a new Corvette from the factory, maybe you should consider it. Happy e-motoring!

Tires look great. Have only had tires a week. Notice little road noise I didn't expect. Like a roaring wine. The ride is also is also not as comfort as I expected. But all in all tire is worth buying again.

I have only had them for about 1000 miles but I replaced my old Toyo Proxes 4 all seasons with these and they have dramatically changed the handling of my 2015 Lexus GS 350 awd. Amazing tires so far in the dry and wet (no chance for snow or ice yet) and I am sure I have bored many people talking about my new tires. They are awesome.

Michelin Pilot Sport A/S 4 tires. Running these on a 2012 Audi S4, all wheel drive car. It's my daily driver / road trip car. Climate is middle of USA. Snow only 5-10 times a year here, usually light snow. Truly 4 seasons. Driven about 20k miles on these tires since 2021. Driving style spirited. The wet handling is really why I love these tires. They are just excellent for a commuter or road trip car when the rain is coming down hard. Snow is fine and suitable to get around a light snow day, but you'll slip around a bit (which I'm fine with) Dry handling is on point for what I need. Very good, but not amazing. Only time they slip is under really hard corning when I'm asking for it. They're expensive, that's a draw back for sure. However, I've been happy with the tire wear so far. Just be sure to do regular rotations. I would definitely buy these again.
