I bought these for my E46 M3 about a year ago, and these are hands down the best performing tires I've ever ran. The level of grip and confidence they give you under extreme cornering situations is amazing. Even in the rain they provide amazing grip, and it can be hard to get the rear end to want to slide. The only downside I would say is that these tires really don't last long at all. I've put only about 12,000 miles on mine, and all four tires are almost bald. But I also drive the car hard here and there, so that doesn't help :)

I bought these late last summer to replace my OEM summer tires. It instantly brought my car to life and made it more capable than i thought it was. No slips no fuss, just instant grip and off i go. The wet handling is confidence inspiring. I know i will be swapping all of my Summer rubbers to the PS4S's going forward. Would and have recommended to anyone looking for summer's.

Put Pilot Sport 4S on my 2012 Porsche 911 Carrera S. It's a proven tire on that car. Performs great. Lots of grip in the dry, and pretty good in the wet, too. Obviously a summer tire and not made for winter or cold conditions. Very happy with the tires!

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.

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 switched to the PS4S from an OEM run-flat, high performance summer tire of a different brand. We went on a 1,400 kilometre trip soon afterward that included western mountain roads, where the Michelins were outstanding. They took our sports car to a new level! Bonus: they ride much better, transmit less road noise, and do not ‘tramline’ (lurch into pavement grooves and sags). They were well worth the price.

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.

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 bought these these tires for a new set of rims that are on my BMW M2 Competition. The tire performance of the 4S is improved over the OEM Pilot Sports. The driving dynamics and stability at the track exceeded expectations. Excellent wear characteristics with good feedback.

I bought a used car with pretty new 4S tires on them. I've not had to replace two front tires due to sidewall bubbles/tears from potholes. I know when they occurred and this level of damage should not have happened to these tires. By looking at the reviews, I can see I'm not the only one saying this. At this point just say they are track day only tires.
