Nitrogen filled tires

[TGC4]

Hi everyone,my first full summer with my baby and what a blast. I had a new set of Goodyears put on my Blazer,the dealer gave me a (free-be) nitrogen filled tires.He says they shouldn't require the pressure checking nearly as often and at oil changes they would check and add as needed.I will be in the market for tires on the Vette next spring-Any thoughts realated to this nitrogen idea? Thanks

My 94 convertible has nitrogen in all 4 tires plus the spare. Had them filled at a Chevy dealer in 2006. After storage over the winter, the spare dropped to 55 psig from 60, and the 4 tires went from 30 to 28 psig. Had them filled again just before CR 07 June 26 and they have not lost air to date. The dealer charged me $20 to fill all 5 tires and I can have them refilled at no charge anytime I want. Their procedure is to remove the tire valve, let the air escape, then refill. When I asked how do they account for the oxygen remaining in the tire since the atmosphere is 79% nitrogen and 20.9% oxygen, they could not answer it. So, the tire would contain more than 79% nitrogen, but less than 99% since they do not remove the air from the tire under a vacuum. But the tires do hold pressure longer. When I looked at their nitrogen machine, it was similar to an air compressor that uses air at atmospheric pressure and compresses it. The nitrogen machine also uses ambient air, but must have an oxygen scavenger system that removes the oxygen from the air, leaving nitrogen and trace compounds. They wanted to put green valve caps on my valve stems, but I told them no - I wanted the chromed ones back on. The spare got the green cap.

You will have to make your own decision, but I would not do it if I could not get refills at no cost. The refills at no cost only apply at the dealer I used. And if your tires get low in pressure, you can top off with regular good old fashioned air, availabe at your local gas station.

Heck, plain old air contains 78% nitrogen. I know the nitrogen in Nitrogen Inflation is not 100% either. How much of a difference can it be? I DO have nitrogen in my tires but I sure can't tell a difference, except for the GREEN valve stem caps they replaced my stock ones with. Did not appreciate that. Got those off real quick. Back to black.

Nitrogen = more consistent pressure changes with temperature. It does not mean you don't have to check the pressures as often.

If it was free, why not get them filled with it. But I doubt on a street car it makes any real difference. Mine were filled that way for free also, but I just refill them with regular compressed air.

The advantages of nitrogen over compressed air is that it is clean and dry. I think someone is trying to sell you air for $20 and to keep you returning to their shop. Its doesnt have any magical substances that seal leaks. Its true that aircraft use nitrogen in tires but you have to look at the hostile atmospheric conditions that aircraft are put thru each fllight. A tire may change from sub zero at altitude to over 200' on touchdown and rollout. Moisture could cause problems with corrosion and breakdown of the carcass. They recap aircraft tires several times. Also main aircraft tires on your commercial jets are running in excess of 200 psi, nose tires usually a little less. When they come in hot, an accurate read cannot be made until they cool, my experience is that they rarely exceed 15-20 psi above what a cooled tire may read. Im certainly not saying dont use nitrogen, as it could cut down on corrosion of your wheels and not fluctuate with temperature changes as much as plain ole compressed air, but dont expect to notice it on a DD.

that bridge just up the road from your house can be yours --special sale this month only-- $20...send selfaddresed envelope and cash only and you'll receive the deed for that bridge and the one in the same spot that u go over coming the other way too.

we use nit in race car tires cause those get hot enough for the teeny bit of water (moisture) in 4/5 nit (household air) to change to steam in RACE conditions...water to steam volume change is abt 1600x...upsets car handling as tire pressure jumps up a bit when flash point is reached...our race tires often show 200F+ when returned from track, doubt that your street tires get even close to that.
