Great tires but they don't last. I'm at 46000km and they are down to the wear bars and not even three years old. Like I said, no other issues except for tread life. I would give it five stars if lasted 80000km or even 70000km . Driven on a Lincoln MKX with no aggressive driving.

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.

I've never written a tire review in my life. I can't help but write something about these tires. I previously had another all-season tire from a certain company with a blimp and the difference between these Pilot AS4s and those are shocking. Smooth as silk ride, whisper-quiet, and traction that is amazing on my heavily tuned Audi 4.0T car!

I purchased a set of pilot sport all season 4 plus 285/45 r20 y 112. I noticed that the tread design on the left of the car is pointed in an upward tread direction (^) and the right side is in the downward direction (v). All four tires say "outside" on tire wall. I have never seen a tire that has opposite directional patterns from right side of vehicle to left side of vehicle. Please shed some light on this and/or let me know if I should return to the shop that sold this set to me. All this being said, tires show exceptional grip and road confidence in dry conditions.

Upsized to 18" wheels & ride is even a bit softer than the AS3's on the 17" wheels. Steering at low speed is a bit heavy with the larger contact patch than the OE 215's. Good grip cold, much better when warm. Side wall flex is a big improvement in cornering.

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.

Purchased my third set of Michelin tires for my third different vehicle and Michelin continues to impress me with the quality and drivability with each new set of tires. This time I purchased as set of Pilot Sport All Season tires for my Buick Regal Sportback and the car drives better than new. I will put nothing but Michelin tires on all my cars from now on.

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.

What a perfect pairing for my older QX50. We've had a rainy December in San Francisco. I usually drive my Jeep. However since installing these Pilot AS4 my old Infiniti 3.7 AWD thinks she is a sports car. My favorite feature other than the handling is wet roads and deep water at 70mph plus there is not a single hint of Hydroplaning. The wheel doesn't so much as tug. I'm talking puddles on I-580 that span 4 lanes of road. Other than a quick flick of the wiper blades; there isn't even a perception you just hit a puddle. Dry cornering at the limit at least on my Infiniti, with the driver assist off and foot on the gas hard, she drifts predictably giving lots of warning. These tires test your driving skills, not the other way around. If you are driving AWD and have 300+ HP I cannot recommend these tires more highly.

These tires have great grip even in the heaviest of rains however you pay for this with 15-20% range loss in all driving conditions in my Tesla Model 3. I normally only drive it locally but now I can't really take it on long trips because it will require charging stops.
