Since I see various questions on approved tires....this is the latest list that Porsche published, dated January 2005. The 'N' designation represents a tire approved by Porsche (there have been articles in Christophorus on the process). There is no differentiation between a tire with a higher or lower 'N' number, that is, an N3 tire is not better than an N1 tire, it's only an indicator.

Thanks Bill!

And well-timed too: my 964 needs some new rubber in a few weeks time
