Just received a set of PS2's from tirerack, all "N3" and was interested to note that the 255/40ZR17's come from Brazil and the 205/50ZR17's were made in France! For some reason I was thinking they all came from one factory in Germany but I suppose the demand means that they have several factories producing the N spec tires.
it appears this is no longer the case (assuming my info was accurate to begin with).
I have Bridgestones on my Turbo and I have a set of new rear tires at the dealer just waiting to be installed -- in a couple of thousand miles when the current tires are down to the wear bars.
I think I'll ask the parts department manager the country of origin on those tires to learn if they were made in the same country as the tires that I had fitted last Nov.
