Purchase these for all-season use in California. Rode these through the recent cyclone storm with no issues. No hydroplaning and complete confidence in braking and cornering. Ride is quieter than I thought. I drive a EV so only noise is from the tires which was not really noticeable. Only thing I would change is the lip of the tire seems to offer little protection for my brand new wheels. It sits flush with the lip of the wheel and I can already foresee curb rashes. If they can bring out the lip of the tire a bit more to protect the rim, I would give it 5 stars. Othere than that, a super high performance tire. I take off fast, corner fast, and stop fast so a high performance tire is required.

I bought a set of pilot sport AS4 to put on my car and I absolutely love them the amount of control and response difference compared to the stock tires was unbelievable and as far as grip goes I have a hard time breaking loose when I try to do it on purpose

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 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 have the cup tires on my GT3, the Ice tires on my mazdaspeed6. And so I bought these for my '18 Model S 100D. They replaced the "quiet" Goodyears OEM at 23,500 miles. After installing the Pilot Sports, I immediately went to the Tesla Service Center in St. Bruno , Quebec for a wheel alignment. I have never touched a curb with the wheels but the car needed an alignment. At this point they are about as quiet as the goodyears. They seem to handle bettter too, but the wheel alignment helped with that too. I have never had a bad experience with Michelins. Even though I purchased them last Winter I just had them installed.

These were quite a bit softer and quieter than the Pilot 3 + tires removed after 40,000 miles. The Pilot 4 AS felt initially like it wouldn't be the same in handling as the 3+ AS but that was totally wrong. They handle great. I would definitely buy them again.

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.

Went from 17 inch To 18 Inch, huge jump in performance (both wet and dry) from the tires Ford put on my 2015 Mustang eco-boost. People told me the road noise would be an issue but quite the opposite. Black car, wheels, tires. Sorry, can't figure out how to transfer pic. from my phone (LG)

Bought these tires about a year ago and have no complaints at all!! They're much grippier than my old tires and are whisper quiet. Unfortunately, my MPG has taken a slight hit, but that's a small price to pay for much more confident braking and handling.

I've had a few good tires in my life, but nothing like the wow factor of this new design. The wet traction is outstanding. This tire inspires a lot of confidence. So much technology with the tread design and the compound. I'm not looking forward to the snow, but with this tire I feel that it will not be a problem. This might be the perfect tire for the Pacific Northwest. I live in Vancouver BC and we get lots of rain. My old set of P Zeros feel like crap in comparison to the Michelin AS4. My Mustang loves these tires !!! :)
