looking for a spot since my tires currently have nitrogen in there now. I bought mine from grubbs and they do that there in texas.

 

I believe Costco uses Nitro.

 

sweet, thanks for the fast reply.

 

Hey, I wish Costco performed more maintenance services for our cars in light of my current woes per the other thread...

 

yeah, a wholesale tuneup would be great


does costco carry vortech?? heh

 

hey john whats the benefit of having nitrogen?

 

Air is about 78% nitrogen, 21% oxygen, and 1% other. Nitrogen is inert, non combustible, and non corrosive. Oxygen on the other hand is a destructive element. When tires are exposed to air, a long term and continuing deterioration begins - the oxidation of the rubber in the tire. As what happens to a rubber band over time, it loses its elasticity and strength. This same process occurs in tires inflated with air as the oxygen attacks the rubber molecules, working from the inside out until the oxygen permeates the tire structure and ultimately the tread.
