I bought mine last fall from TR in the standard winter sizes: 235/35v19 and 295/30v19. They run out pretty fast, so I'm not surprised that they are NLA this season. Since TR don't normally carry Nokians, you'll need to call for the Porsche package.

BTW Nokian still lists these sizes on their website, so I don't think they've been discontinued. Just NLA from TR at this time.

BTW there's a thread on Rennlist in the wheel/tire forum from Damon@TR. He posted in Sept on the availability of n-spec winter tires including the Nokians.
