Gone but not forgotten
As Hib points out, adding nitrogen to the tires may or may not be beneficial. I was really interested in the Oxygen suckers he offered, because even when filling the tires with Nitrogen, the tires still has 21% oxygen left in them when drained and refilled. I was going to purchase 4, one for each tire. The price seemed okay since Hib offered the BOGO for $40. The nitrogen system used at the dealers scavenges the oxygen from the atmosphere (which is the source of the "air" being placed in the tire) when filling each tire, but there is oxygen remaining in the tire space since they do not evacuate the air from the tire. I only used nitrogen in the 94 to keep from checking the spare every two months (dropping the carrier is a pain) and it does keep the tire pressure at the correct level on the other 4 tires in use. So, when I drive by the dealer every year in the 94, I have them refill with nitrogen. Too expensive to fill all of my vehicles with nitrogen, besides I do have a large compressor in the shop and check pressure monthly. I had read Hib's articles on the nitrogen for the tires, and they were mostly responsible for me not adding it to the run flats on my 02 coupe. Just my $.02 worth now that the stimulus check will be forth coming shortly.
