2004 Carrera Cab, 14K miles
Currently running 295/30ZR-18 N1 Michelin OEMs on the rear and one of them is worn to the metal along the shoulder edge.

I am new to the Forum and don't know if this is the correct place to post this inquiry. I would like to get some input on replacements for the 2 rear tires which were original equipment on the car. I am trying to decide between new N1 or N2-6 Michelins, Pirelli P Zero Systems (N3), Rossos (N5) or Corsas (N6), and Bridgestone Potenza S 02 (N3). I use the car as a daily driver (no track days).

For the life of me, I cannot figure or find out what the difference between the various "N" numbers is and whether anything other than the N1 is right for my car. The front Michelins have plenty of life left and maybe, since I am keeping them, I need to go with the Michelin Pilot Sport which is an N1. On the other hand, I have heard good things about the Bridgestones and Pirellis (although neither of them offers an N1 tire N2 or 3 or 5 or 6, but not N1.

Is there any wisdom out there on what to do and what to expect? By the way, I am in Los Angeles, so wet weather is not much of a problem.
Thanks much.

 

The N Rating is a Porsche nomenclature requirement. Fora Porsche theZR Rating is key for the ability of the tyre (tire) to cope with the vehicles speed capability.
If you only need one tyre (tire) I would replace Michelin like for like so you have the same spec tires on the same axle.
If you need to replace all 4 in the future take a look at Yokohama Advan Sport.
I've fitted them to my car with Victor Equipment Wheels and roadholding, wet performance, and wear durability all seem good.

Matching the tire (brand/model) is key to a well behaved Porsche. So I agree that if you have only two to replace, buy the matching Michelin's. I am a big fan of the PS2's myself, and really dislike (with a number of trials so I am thoroughly convinced) the Pirelli's.
