Nitrogen in trailer tires

Is there nay benefit in using nitrogen in my Monty's tires?

Only if you get above 15000'. Used in aviation mostly. A hassle finding on the road.

Besides, common air is 78% Nitrogen, and even adding pure Nitrogen to a tire would not eliminate the air already in it before pressuring it up. A total waste of money, and a big money-maker for the tire shops that use it.

Never used it, never had any tire issues. Run good tires, watch your air pressure and don't go 80mph.

Yup, I always looked at it as another way to separate me from my money.

Pure nitrogen would be more stable than breathing air, but it would be expensive to put pure nitrogen in tires. It would be difficult to replace if needed, I think disadvantages would out weigh advantages, my $0.02 worth

It also works well when you're traveling over 200 mph.

Just a gimmick, IMO.

Nitrogen is a gas and is still affected by changes in ambient temperature (about one psi for every 10į Fahrenheit). Nitrogen filled tires will require pressure be added during the fall/winter months as ambient temperatures and tire pressures drop. Nitrogen is good but can't change the laws of physics.

Nitrogen reduces the loss of tire pressure due to permeation through rubber over time by about 1/3. This helps maintain the vehicle's required tire pressures a little longer, but doesnít eliminate the need for monthly tire pressure checks. This is good for people who donít maintain their vehicles well.

Nitrogen is non-corrosive and will reduce oxidation and rust due to the absence of oxygen and moisture. This will help minimize wheel corrosion to promote better bead sealing. Tires that are used routinely will be replaced long before any life benefit would be received by using Nitrogen. This is most beneficial for drivers who drive their vehicles infrequently (car collectors, track drivers, snow tire users, motor home owners, etc).

Nitrogen is a dry gas and will not support moisture that could contribute to corrosion of the tireís steel components (bead, sidewall reinforcement and belts) due to the absence of moisture over extended periods of time. However itís important to remember that atmospheric pressure is constantly pushing oxygen and moisture into the rubber from the outside of the tire. This is especially good for low mileage drivers who don't wear out their tires quickly or those that run average annual mileages but use long wearing radial (60K and 80K warranted) tires.

Nitrogen assures more consistent pressure increases due to increases in operating temperatures in a racing environment because of the absence of moisture. This is especially good for participants in track days, high-performance drivers education schools and road racing.
Drivers should use standard air if pressure adjustments are required when a local source of nitrogen canít be found during a trip. While this reduces the benefit of higher nitrogen content, it is far better than running the tires underinflated in search of a source. Often the original nitrogen provider will refill the tires for free or a nominal cost when the driver returns to his hometown.

While inflating tires with nitrogen never results in 100% purity, most nitrogen service equipment providers advise that reaching at least a 93% to 95% purity is necessary to receive the desired benefits. This ratio is normally achieved by initially purging the tires of existing air (down to just a few psi) and then refilling them with nitrogen. The purge/fill cycle is often repeated to achieve the desired level of nitrogen purity.

Overall, inflating tires with nitrogen won't hurt them and may provide some minimal benefits.

Is it worth it? If you go someplace that provides free nitrogen with new tires, why not? Additionally weíve seen some service providers offering reasonable prices of about $5 per tire (including periodic adjustments for the life of the tire) to a less reasonable $10 per tire (with additional costs for subsequent pressure adjustments) or more as part of a service contract, which we believe exceeds the value of nitrogenís benefit.

Rather than pay extra for nitrogen, most drivers would be better off buying an accurate tire pressure gauge and checking and adjusting their tire pressures regularly.

Our F350 was supposedly delivered with dealer installed nitrogen. After a flat, the nitrogen in one tire was replaced with air. Our pressure monitor showed virtually no difference in pressure or temperature between the nitrogen and air filled tires.
