PS4S on my 911 seem to be performing well. Quieter, with good grip in the dry. Haven't had the opportunity to try wet roads. Consider these tires for your 911.

While these tires had excellent performance in dry and wet, they were too fragile, i had one go out due manufactuer defect. Then another another one go out from hitting pot hole.

Tires performance as described. A little on the expensive side.

With 11,000 miles both rear tires are down to 4-5 tread wear, so need to replace them already.

Both my car and I love these tires!

To date I have been pleased with the handling and performance of the tires. Hoping to continue that trend. Would not have any negatives to report.

The tires are great and perform well. But why would a OEM supply these tires on mew cars when you can't use them below 40 F?

I am an avid Michelin user. I have them on all of my family vehicles and on my high performance vehicles.

I've always enjoyed putting Michelin tires on my vehicles as they are reliable and provide traction and stopping power. Hope there will be a promo in the future that will allow me to afford them when ready for a new set of 265/30/19 93Y. Thanks for putting out an amazing tire product Michelin!

Though it appears to have a miniscule roll drag increase over N type tires, on dry roads they virtually handle equally, but on wet highway use make a large differance. Not what I would buy for use on a dry track, but for commercial road use, they are amazing
