+1. I had half the tread remaining on my P Zero fronts (only 12k miles), but I was happy to recycle them and put new P4S rubber at all 4 corners. It no joke transformed the car (for the better).

Doing that with the 911 I picked up in October. Have all-seasons on it right now but in a couple of months I'll swap out the practically new P Zeros for PS4S N0s. Will keep the P Zeros in the attic and put them back on the car when I sell it.

Recommend Tire Rack for the Michelin Sport 4S. They come with 2 yrs of Road Hazard. They have a list of recommended installers showing the price. Some Porsche dealers with install also. If you have TPMS with batteries consider replacing with the new tires. I used Titanium for replacements. As others have stated 2 sets of rears for each front is typical. Rears typically wear more on the inside based on the independent suspension. I've swapped the right rear to the left to squeeze out a few more miles. You have to reset the TPMS. Four wheel alignments are expensive but necessary. I've you autocross or DE you should consider additional negative camber for the front.

If you are looking for a bargain tire, check Atlas Force UHP. I got them about 3 months ago, very surprised how much I like them. I thought I was going to just use them for the winter since they are AS, but I am going to just keep them on al the time.

Thanks for the comments everyone. I swapped out the tires with the Michelin 4S'. I didn't get to put any significant miles yet, the weather is sort of bad out here. My first impression is that they are significantly silent and stickier than the Pzeros.

Interesting. Yes, the tires are definitely softer than the Pzeros in turns, but I would need to drive on them more to see if they feel weird. I have the PS4s on my 335i and they do great on that car.

I think you'll find the wet grip of the 4S's pretty remarkable. Great feel/feedback when you start to push a bit.

I need to replace all 4 tires on my 981C 2.7. The Pirellis worked for me, but after reading this, it's going to be the Michelins! Thank you.

As I've already stated if you chose the Michelin 4S at least price compare using Tire Rack. The Tire Rack test ranks them as clearly number one. I'm not at the point to invest in another set of wheels with pure track tires like Hoosiers. I plan on driving to the track, on the track and back home on the same set of tires. I don't know of anyone who beats the price including their free 2 year road hazard. I had them shipped to a local Indy tire shop from the Tire Rack list of installers. Make sure you print and take the install price from the Tire Rack site with you otherwise you will pay more. I don't think the extra some shops want for "precision" balancing provides any better results than normal spin balancing. If you track the car invest in the heavy duty aluminum duct sealing tape, not gray duct tape, from Home Deport or Lowes and tape over your wheel weights. You can do it without removing the wheels, you have more room doing the back with a smaller caliper. A tip from a PCA member. I didn't throw any weights but I had two come off in my hand when I washed the inside of the rear wheels. I took off the wheel and could see where they had come from. The installer gave me two wheel weights. Sometimes I welcome the rain at the track since it greatly reduces the number of cars on the track. Those with pure race tires either sit it out or have to put back on their racing wet tires. The Michelin 4S have a very good rain rating.

First of all, love the username.

I had the chance to drive my car yesterday with new tires and would recommend the switch. The wet grip is night and day compared to Pzeros.

ordered already. But still a month of winter tires to come!
