Many of the tire dealers around here are now offering to put nitrogen in the tires. Cost is about $28 for 4 tires. They claim the pressure does not flucuate with the temperatures, and the ride is better. Possibly some more mpg. Does anyone now have nitrogen in their tires, or have any experience with it? Thanks for your input as I am interested in putting it in the tires of my 2005 F-150.

 

Tell ya what,you send me the money and you'll feel much better.

 

Got mine done for free when i got the truck..

 

Not much benefit for street tires other than making more money for the tire store.

Save your money.

So, now that I read this, I might try helium. Heck it would make the truck lighter, and give more mpg, and power to the rear grinders.

 

Don't forget the spare.

 

Nitrogen makes an excellent tire inflatant for several reasons. Nitrogen is inert and oxygen-free, so it does not oxidize the rubber in the tire or support corrosion or rust in wheels. Nitrogen does not leak as readily and tires retain their inflation better than with compressed air, and it handles heat better than oxygen-bearing compressed air too.

Those considerations are important in heavy aircraft and long-distance truck tires for various reasons, but they haven’t proven critical in passenger-car applications. Passenger-car wheels don’t typically rust or corrode from the inside, and passenger-car tire carcasses are only used once, whereas aircraft and especially truck tires are typically recapped, so they need to last much longer than passenger-car tires. Many 18-wheeler truck carcasses log 250,000 to 300,000 miles, for example.

Rarely driven specialty cars may benefit from nitrogen’s ability to more consistently maintain tire pressure, and tire life may be extended somewhat. Still, nitrogen filling doesn’t help with atmospheric oxygen and ozone, which eat away at the outside of the tire, so archival effects should not be expected.

Given that compressed air is as economically available as the nearest air compressor, and nitrogen requires either a $5000 nitrogen generator or handling heavy bottles, compressed air will be whistling out of air chucks for some time.

That said, expect to see nitrogen filling as an extra-cost option at tire stores and specialty garages as commercial truck nitrogen-generation equipment is marketed to the consumer market as an extra revenue stream.

good luck -jim

 

The part of PSI fluctuation is correct, as for ride...well.......NOPE

 

So lets see compressed air is 78% nitrogen 20% oxygen and 1% of other inert gasses.
So based on the theory of 100% nitrogen, which is only 20% more then compressed air doesn't it stand to reason the claims are bogus for everyday use!

For the use in airplanes I understand since the temperature differentials are a lot greater then for everyday auto use.
BTW you don't keep tires long enough to see oxidation take place from the 20% oxygen.

It's big marketing hype, and I hope it falls on it's face, just like PTFE additives in Slick 50 etc..! Buyer beware!

But I will say those green valve stem caps do bring some bling to the vehicle!

 

I have nitrogen in both my vehicles, and I have to say I have had a slow leak in my 2001 ford focus since the day it was new, and I got nitrogen put in and it quit leaking. I have noticed a difference in ride and handling and as for mpg I borrowed my sisters expedition and she said that she never could get over 13 mpg and I had nitrogen put in her tires at her expense to try it out and i got 16.55 mpg on a all highway trip and she said even all freeway she could only get 13 mpg. So it did raise it. I personally think its 25.00 if it doesn't work its only 25.00 so its worth a try.

 

Com-on compressed air is almost 80% nitorgen. Who's kidding who! the difference is you were driving and not her! Ride and Handling think you are now grasping at straws!

 

At work they use nitrogen in the tires to fight the extreme heat buildups we get. They still have to check the pressures every couple of days.

Just get an air compressor.

 

Between the nitrogen in the tires, Tornado in the intake, and magnets on my fuel lines, I'll be selling fuel back to the gas stations pretty soon!

 

Bill C good one!

 

The moisture and the o2 in normal air tend to expand more when heat is applied, causing tire pressure to rise. I used nitrogen on my racecar because it maintained a better pressure thru constant temp changes. That being said the average person is not working their tires as hard as someone on a race car. I do not know if their would be enough benefit to using it on a regular vehicle to be worth the trouble.
