The Michelins I got are actually the "Cross Climate", NOT the "Pilot Sport". They cost a fortune but I've decided they are worth it. In addition to being winter certified the handling, ride and road noise all significantly improved. Quite amazing. A lot like having a different and better car. You won't regret having these.

Excellent tire. The compound is sticky and aggressive while still offering good traction in cold weather. The tires appear to be well made with a very still XL-rated sidewall. Handling is extremely precise and predictable with perfectly controlled behavior when approaching the limits of cornering grip. The tires are very comfortable and pretty quiet for a performance A/S tire. While I cannot comment on tread life or highway stability just yet, no doubt those will meet expectations as well.

I usually just get the most highly rated winter tires for EV. This one is good; no problem nor negative feedback so far. Of course, it comes with a higher price tag, so take advantage of the rebates they offer.

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.

For an all season tire, it is good on a dry, cool, onramp for lateral g-force, but traction loss is inevitable during medium parking lot to road acceleration in warm weather (30°C).

VERY QUIET, SMOOTH RIDE, AMPLE TRACTION,CORNERING, AND BRAKING.

I switched from PS 4 to PS All Season 4 for my 2015 Mustang (not staggered). Great tires? Yes. Very comfortable, with good performance. Before buying I had read that the AS version gives up little in dry performance - of that had been very true I would give a 5/5 testing. The compromise in all out traction is greater than I expected. But great tires that I would recommend? Definitely and I have no regret stepping down from hard core performance (the PS4 is amazing!) for more comfort and safety in lower temperatures and even light snow. Lower noise. Either tire is a great choice.

I have been a Michelin owner for more than 40 years and have only had 2 issues in all that time. One was a bent suspension arm that tore 2 tires to shreds. The other was a 3 inch spike that blew a tire, neither of these were Michelin issues and have trusted the brand forever.

Tires were balanced at install, and twice more after that. Still a vibration.

Unfortunately, I cannot recommend these tires. This review comes after driving 50,000kms, city and long distance highway driving in an AWD vehicle. Tire size is 265/40R/21. Maybe this tire is not ultimately suitable for a low profile vehicle, I'm not sure. As I often read reviews before making a purchase, and I did before purchasing this tire, I feel compelled to write a review with my experience. In my opinion, this tire lacks stability and handling ability. They've always felt slippery in rain and though the first year was somewhat bearable in snow, since then they've been poor. On dry surface they roll into (vs. over) any groove in the road (think crack in the road that has been filled with tar); the tires feel like they are sinking into the tar. They've never felt like they have enough air, though I've repeatedly checked the level. Today, I felt like I was 'skating' while driving in 2cm of snow. No traction whatsoever. I have always put Michelin tires on my cars and have always been happy with them. Sadly, that hasn't been the case with this one. I will consider another Michelin tire, I just can't recommend this one.
