Nitrogen filled tires- Does it help with pressure loss in changing temperatures

So I run 37"x14" tires and the summer/winter temperature fluctuation play hell on my tire pressures. I adjust pressures weekly. Has anyone ran nitrogen and what was the result? Does it make a difference?

Looking for real life experiences, not interested in opinions based on an article you read in Car & Driver.

No

I'm going to let you in on a deal though. I've got some 78% nitrogen-air supply that I can sell you on a big discount

Let me know if you're interested

I wouldn't waste your money. I have nitrogen from the factory, and haven't had any problems with pressure. But I have never had problems with air in the past. When it's time to top em off or air them up, there is no way I'm wasting time and money to try and find a nitrogen source. Air ftw.

Absolutely helps. Is it worth it? Depends on the price.

33x12.50x20s here.

Absolutely. If you can afford 37s you can afford nitrogen and it makes a pretty big difference. Mine were fluctuating about 8-10 psi before nitrogen. 3-4 psi changes now.

I think I just have a slow leak in one of my tires, but I had nitrogen from the dealership in my Tahoe and I've never had to keep adding air like I have with this vehicle. It's not enough to make me get new tires, but it's enough to be annoying.

Want to know why this fad is so popular?

quote:

quick look at a few of the nitrogen generator manufacturers' websites can give you an idea what may be driving some of the interest in swapping tire gasses. N2 machines can operate for as little as 25 cents an application. The generators themselves go for as little as four grand. After the first 200 or so nitrogen fill-ups, these things are more profitable than pretzel carts.

it's what they put in aircraft tires, for a few reasons, extreme temp swings, pressure fluctuation not an issue

My dad did it for a while, I think more for novelty more than anything else.

Nitrogen is a inert gas ! The pressure does not fluctuate with temp.
