I'm on my second tire set. As fellow AW posters have said, it's more stable due to the lack of Oxygen which expand/contract due to heat. And no Oxygen means it eliminates corrosion. However, that's all theoretical because Oxygen is bound to enter the tire somehow.

And if you do decide to go to Costco, beware their records on the Audi A4 inflation guide because they have it all wrong with the 17" and 18" OEM option. I've fought them over this and told them to update their records, but everytime I come back, their inlfation guide is still whack. I debated them on this and showed them the door panel and the manager of Costco finally called me to apologize and said they will contact Audi and have their records updated.

I haven't gone back yet, but will soon when I rotate the tires. Will see if their records are still out of spec.
