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.

Both my car and I love these tires!

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

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.

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.

I have 32,000 Km,s on my tires and still have all kinds left, I can drive my car in the rain even now. They are a little pricey but well worth it in the long run. I have been asked many times how much I have liked then and given a good review. In the summer I use the car daily

Excellent tire. Handles like it is a set of RR tracks. Question - what is the minimum temp for driving. This tire is on a Porsche 911. We live in TN and still have nice days in the winter. But, we have a northern route road trip planned, not in snow and ice, but possibly with temps below 40. Nights could dip below freezing but we won't plan to drive then. Is there an absolute "do not drive" temp where we could do tire damage or be unsafe?

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.
