My 991.1 S Cab has 245/295 tires. Would like to go with the PS4S in the N spec but I don't see them on Tire Rack. I have the 8 1/2"/11" 20" Carerra Classic wheels. Has anyone found those tires?

 

Change your search for a 991.2 (such as 2017 year). Just note N0 is only available for 245/305

 

Get the 305 rear.

 

I got mine at Costco. Put the 305's on the rear. They had the N version, but they offer several so make sure you get the one for Porsche. The other N was for a Ferrari and others I think

 

This is what I bought from Tire Rack a couple of weeks ago to replace my Pzero. I made sure it was the (NO) spec for Porsche

For record I got mine pre N spec availability and they have been awesome on Track and in the Rain here in CA. Just in case folks wanted to venture off the N spec tires

 

I'm also running these tires in 245/305 configuration

 

I changed from 295 to 305 on the back. Much better

 

I got PS4S non-N-Spec for my 20" Carrera S wheels before they ever made an "N-Spec" PS4S. They have been an awesome tire. I wouldn't worry too much about N-Spec unless you drive your Prosche to its limits on the track (and then why would you use PS4S when there are better tires suited for the track).

 

I would like to add the following link regarding 305 in a narrow body. It is applicable for both the Carrera S and sport design wheels in the 991.1. It is all about offsets

tires designated for ferrari is "K"

 

Porsche will put them on for you no problem. It's just a 305 rear. I had my dealer do it last service and it was no biggie.
