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.

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.

These handle really well and helped me out a lot with the big rain we get in Florida. Unfortunately, 2 tires are down to 3 and 2/32nds. 2 Tires are down to 4.5/32nds. I have about 20k miles on the tires and drive on the highway mostly. Florida roads can be pretty rough since they get baked, so I imagine this is a leading cause. I'm hoping to get some warranty on the 2 tires that are near the end.

I originally bought the Michelin Pilot Sport A/S 3+ with a wheel and tire package in 2016. Those tires were very impressive and held up well. When I had to get new tires, the Pilot Sport A/S 4's were a no-brainer. I've had a while to give them a full and honest review. In dry conditions these tires perform just as well as any summer tire on the market. There is no lack of grip in cornering and little to no road noise depending on the condition of the road. In wet rain conditions these tires grip the road very well and keep the car grounded through corners. In snow conditions the tires do pretty well, depending how much snow. I have had some traction issues in over two inches of new snow. Obviously in these conditions, you use your best judgement and use an abundance of caution and maybe even opt for a winter tire if conditions call for it. Overall they perform well in cold conditions up to -10 below. I've never had a traction issue on cold dry roadways using these tires. Ice and snow may bring a little bit of traction issues from a dead stop, but once you are up to speed you will have enough grip to make it home. After close to two years of driving with roughy 30-45k highway miles (and not always following the reccomended tire rotation intervals) all tires are at a 7/32 tread depth and still have plenty of life left. Someone may look at the overall price point and opt for a cheaper tire option, I wouldn't call it the most "economical" option. In terms of "you get what you pay for" these are worth every penny. There's a reason you see plenty of performance manufacturers putting Pilot Sports on from the factory. It's not a gimmick. These tires will last much longer than other brands, and will continue to deliver the performance and safety you expect from a brand like Michelin.

Had these on my Golf R AWD for a few month now and with the recent 4" dump of snow I have had the chance to drive these in all conditions. Performance has been outstanding, great dry and wet control, excellent braking and these got me out of my steep driveway where the OEM's left me stuck. Highly recommend these for all season sports car applications as they don't compromise performance.

Had to replace the tires on my 2018 Civic Sport and I can’t believe the difference. I previously had some “high-performance” Falken tires that weren’t bad but after a couple days with the Michelin Sport A/S 4s I finally understand. This is the first Michelin performance tire I have ever driven on and my car is a completely different machine on these tires. The level of grip is superior to any tire I have ever had, even in the rain. My car feels like it is floating until I cut the wheel and suddenly it becomes glued to the blacktop. I am a very aggressive driver and understand the value of having tires you can trust on your car and I love these tires!!!

I drive a RWD P85+ Tesla Model S, which is both heavy and up until last winter had staggered 21” wheels. I was used to buying a new set of Pilot Sport 4S for the rear every 10-12k miles, which is to be expected, but not welcomed on that setup. I switch to 20” square rims front and aft, and also switched to Pilot Sport AS 4’s ,245/45/ZR20 99Y, and couldn’t be happier. Now that I can rotate tires life if grand. I’m used to extremely irregular wear and regular pinch flats, but I’ve got things nailed down now. Tire wear with theses tire is even, traction is more than adequate and tire noise is drastically reduced.

I bought the tires early March so far so good. I've had 2 days with light snow, 1 week of rain and a few mild days. No complains. Just bought a second set for another car + Pros: Grip, Stability, Braking, Cornering, Tread Design, Quiet, Steering Response, Visually Appealing, Comfortable,

Great tire. Extremely predictable and high levels of grip both wet or dry. Very quite on the edge of it's grip. Tread life is also amazing. Other tires don't last as long. I drive hard and I don't do silly things like smoking the tire or donuts in the intersection. No sure if it is a thoughtful engineering thing but I like how you can always tell it is time to change the tires when the ride gets rough and noisy. Even my wife who doesn't pay attention to these things notice it but I don't tell why it is so noisy and she can feel how rough the road is. The crazy thing is the grip is still there. Well as long as there is yread but I am still careful in the rain because the tread depth is there so I make sure I have room to correct.

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.
