I’m always amazed at how tires can completely change the driving dynamic of a car. When I purchased my Mercedes-Benz a year ago it came with the original OEM run-flat tires which were absolutely horrible. They gave such a harsh and noisy ride which one wouldn’t expect from a luxury car. However after replacing all 4 tires with the Michelin Pilot Sport 4S it now drives incredibly smooth and quiet. I feel like I have a brand new vehicle. This is how I wanted it to drive from the beginning. The handling is more predictable and solid. I even feel secure and sure-footed when driving in the rain. The thought of trading it in for a newer model crossed my mind a few times prior to getting the Michelin Pilot Sport 4S but now I’ve decided to hold on to it because it drives so well!

I replaced the tires with the All Season verison after 75 miles. Tires pick up small stones and the stones leave holes in the tread when removed. The all season version don't pick up stones and are perfect for street driving. These are track tires and shouldn't be sold for street use.

Terrific grip, absolutely unacceptable noise levels. I have less than 500 miles on these and it sounds like a freight train. I have never in 30 years of driving been this frustrated with a tire choice. My Alpins are significantly quiter..to top it off I find out AFTER having em mounted that Michelin says DON'T TRACK. Did I miss that in the adverts somewhere? Pretty frustrated here. Seems some sizes make noise while others don't, just my luck!

Thankfully these came on my new 911 that I ordered (you can't specify tire brand) - much preferred over the Pirellis Zeros that typically come on new Porsches. On my previous Boxster, I switched from Pirelli to Michelin Pilots and was pleased. Note: I don't track my cars.

I bought these tires a few weeks ago. They are on a 2014 Porsche Boxster. I like the handling so far. I noticed that they feel loose when they are cold but seem to get stickier when warmed up. Still too early to say how they are overall as I have no experience in wet conditions yet and less than 1000 on them.

I purchased these for my BMW with the understanding that they are a Maximum Performance Summer tire and thus have a shorter tread life. These tires are remarkable!! Outstanding dry grip, surprisingly high grip in rain/wet conditions. This particular car doesn't get driven in the snow as THEY AER NOT SNOW TIRES!

I’ve had the PS4S’ installed for a few months now and what a difference in performance. The grip is unreal compared to my previous max performance tires. They’re great in the rain as well. The most impressive quality, to me, is how much smoother and quieter they are. This is just an amazing tire!

I just replaced the Goodyear tires in our MB S class and I'm shocked to tell you how noisy these tires are! I just drove 150-200 miles and I think I'll take it out ... at this point I'm looking for another option and I'll probably test two or three variants and as soon as I'm satisfied with the performance I'll find it I'll warn my friends to avoid making the same costly mistake as me. On the other S Class car I used the Yokohama brand and they didn't look as noisy as the much acclaimed Michelin Pilot Sport 4S! I will also test SP SPORTMAXX GT which seems to be very quiet and smooth ... even other brands seems to offer good variants.

After using PS2 for years, I switched to the PS4s. The 4s appear to have softer sidewalls which helps reduce road noise, while retaining the traction and handing. I can still experience the excitement of twisty back roads and exit ramps performance without the Mrs complaining about the road noise.

I must have driven less than 5000 km on these tires on my Audi Q7 Technik there are side bulges on 2 tires. These 2 tires have the same DOT. The 2 tires that are alright have a different DOT compared to the defective ones. I am a very careful driver. I do have additional winter tires on rims hence the mileage has been low on these tires. disappointed that an expensive tire is not made to last.
