I just replaced Continental run-flat tires with the Pilot Sport All Season 4 (non run-flats). It is made a massive difference. The tires ride smoothly, steer precisely, braking is improved, and wet performance is so much better and confidence inspiring. A great combination of both sport and luxury. As to a number of comments about the tires being noisy, they really aren't any noisier than competitive tires or the tires predecessor, the A's 3+. I think it's just that the tone of the noises a little bit higher pitched and therefore more noticeable to some people. On the other hand, I noticed that there is no noise difference when driving on asphalt and concrete, which is unusual because most tires tend to be louder on concrete. Not so with these tires.

Was looking for a new set of tires for my car recently. I had a set Pilot Sport A/S 3+ and was going to have more installed but the guy at the tire shop said they had the new Pilot Sport A/S 4 and asked if I wanted those instead. He told me they were the newest latest tire so I figured why not. Immediately I noticed a lot more road noise... I mean a lot more. The A/S 3+ was quiet and smooth all around. The 4 is a tougher ride and a lot louder. Not instantly pleased with this purchase. I hope they handle well in the rain and snow—otherwise I'll have to chalk this purchase up as a negative one and will be looking for something else in the near future.

I bought these tires 5 days ago and they flat spot overnight. I've never had a tire do this to me in my life. I had high expectations for these as i have always wanted Michelins. The issue goes away when the tires warm up but the colder it gets the issue doesn't seem to go away once it warms up.

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 just got a set of All Season 4s after running the previous set since 2020. Before replacing them, I took the old set to the track, and even below 2/32" tread depth, they provided remarkable grip and performance.​ The new tires feel outstanding. They're somewhat quieter— even though I never noticed that the previous set became slightly noisier as they wore, it was never intrusive. These tires inspire confidence, offering exceptional grip during spirited drives while maintaining comfort and quietness on long highway trips.​ Driving a vehicle designed for both performance and comfort, it's impressive to have a tire that doesn't compromise on either aspect. The Pilot Sport All Season 4 truly delivers on both fronts!

Just purchased one 275/40/18 tire for Mercedes Wow these tires are light weight ,softer rubber texture Very limited amount of road noise. These tires somehow makes me feel more secure driving in the rain because it Has like minimal slipping It gives you an straight ahead planted feeling while driving in the rain even above highway speeds (You generally shouldn't do ) On dry roads it creates perfect grip , turns where I point the steering wheel My car is a 5,145 pound Mercedes s55 and the tires makes me feel confident and more in control. But like they say on reading rainbow ,don't take my word for it, buy the tires for yourself ! And you'll see what I'm talking about first hand

I no longer engage in terribly spirited driving (its been 25 years since racing school), but I still appreciate a superior sticky tire. I have also gained a fondness for a quiet , smooth ride, which you normally don't expect with a performance tire. I was therefore pleasantly surprised at how much these tires delivered all these qualities with so few of the usual compromises. For my purposes, this was an excellent choice, with much more grip than the OEM tires, and equal smoothness and very little more road noise. Unless you think you want a super stickey tire ( and are willing to pay the price in dollars and discomfort), I recommend the A/S 4. It looks like the new standard for an all season performance tire.

I waited to purchase these All Season 4's because I previously had the All-Season 3+'s on my last vehicle. I wanted to try the newest version. The A/S 4 is incredible. It feels grippier and more progressive as it transitions in a slide. The grip level is incredible for an all-season tire. And they're very quiet - noticeably quieter than the A/S 3+. As an added bonus, the sidewall and tread of this tire is great looking. Little details like placing the tire warning's along the rim protector as opposed to on the sidewall and the "velvet-look" logos. I'd definitely buy these again and have recommended them quite often.

I am hesitant to give a 5 star, because these tires on my Miata, seem to lack smooth steering. For example, when you just slightly turn the wheel, it jumps like it had difficulty going over its own tread?????, then when you turn back slightly it sticks and jumps. Very subtle, different then the OEM tires that were on the vehicle. Wish I really knew what was going on. Air pressure is what is on door jam. I may vary tire pressure and test.

These tires are a huge upgrade for me. Comfort, handling and traction are all greatly improved. It's the one repair I've made to my car that I can feel an immediate difference with. They seem durable so far, only been a week and two days, but I have noticed they aren't all that quiet. That could be do to the materials used to build my vehicle too though.
