Hi Brother,
I need your advice. I was told that all Porsche vehicle need to use the types with "N" specification. Otherwise, the warranty will be voided.
But when I try to check this up with Advan Shop in HK, they said all current 22" types in the market are no "N" spec. So it is not possible to buy a 22" type which can follow Porsche's requirement.

Any comment?

 

I have no problem on mine they are Z rated

N rated just means they cannot be plugged for a flat that is all

 

There was a thread on this a while ago, had a list of Porsche approved tires. Do a search and it will turn up.

 

Actually, scroll done and you will see the post.

 

Non N spec tire won't void your warranty. Just don't get a cheapo tire though as many have reported issues such as vibration, poor traction or braking with less known brands.

 

Thats correct, this is the main idea.
