Tires filled with nitrogen boosts mileage. Is it worth filling @ $20?

I check tire pressure often enough it isn't worth bothering with.

Costco uses nitrogen and fills your tires for free

Here's more on the Nitrogen Snake oil.
https://powertank.com/truth.or.hype/
http://www.getnitrogen.org/sub.php?view=getTheFacts&subpage=checkpressure

If you want to follow the logic:
CO2 is 232.6 pm, 4-5 times the size of Nitrogen or Oxygen, therefore CO2 should be the best gas to inflate your tires.

Butyl rubber is impermeable to air.
http://www.irsst.qc.ca/media/documents/PubIRSST/R-785.pdf

Any leak is not through the tire, but past the tire/wheel seam or the valve stem.
http://www.popularmechanics.com/cars/how-to/repair/my-tires-have-no-holes-so-why-are-they-going-flat-8833288

Oxygen atom is 1.47 Angstroms(48pm) and Nitrogen is 1.5 Angstroms(56pm). The difference of 0.02 Angstroms(8pm) will not make a difference.

HOUCKSTER you are correct. I've been in the car repair business 40+ years and you are so right. We have Tire Pressure Sensors because too many people don't check the tire pressures on their vehicles. Service intervals on new cars are 6 months or more and that requires a gas that is more stable than regular air for the general public.

Send me $10, fill your tires with air, and I'll remind you to check you tire pressure. You will see a boost in mileage...

If you are an individual that checks your tire air pressure regularly I can't see the value in nitrogen in tires. Personally, I feel its another gimmick but if a company such as Costco will initially fill new tires purchased and then "top off" as required, fix and refill tires after flats, and not out in any way out of your normal daily drive then what the heck- go for it.

BORSHT asks: How much of an increase in ecconomy should one expect?
____
Nitrogen provides no benefit against a properly inflated tire with air. The advantages of nitrogen include the ability of the tire to maintain pressure which means more convenience, avoidance of the potential corrosive effects on the tube with oxygen, and less radical changes in pressure due to temperature.

If you always keep your tire pressures checked, nitrogen is of little value. If, like many, they are checked during every blue moon, nitrogen can save on gas and treadwear as a function of underinflation.

One poster writes: Wherever you buy your tires should re-inflate them with Nitrogen for nothing if they use Nitrogen. Otherwise I am not sure it will be that much of an impact and certainly not enough to offset the $20 you mention above.
______
Too often, people look at the immediate cost of something and make a decision on that one factor. In this case I think it's a mistake. A set of radial tires can last 40-60K miles these days. That's several years for most drivers and in that time they will have to check and possibly add air to those tires at least once a month if they want to keep the tires at the proper PSI. If nitrogen cuts the frequency by half, that certainly seems worth $20 to me.

Also, while COSTCO may provide nitrogen free of charge, others may feel the need to charge something since the nitrogen machine does cost money to purchase and maintain.

When one buys tires @ COSTCO they automatically fill w/nitro.

Unless all tire manufactorers cheapen their tire inner wall textures,I won't be needing the Ni... options,I pick tire brands because of their ability to be trouble free,so far that's been the past good results.....

Houckster nailed the situation exactly. I never believed in this magic gas myself but reading the postings here, doing a bit of research on leakage rates, and finally admitting to myself that I rarely check my tire pressures, I've concluded that Nitrogen has a very positive effect for the "average" car owner.

Of course, I haven't installed N2 yet, but admitting the reality is the first, and biggest, step.

I would not pay more than a couple of bucks a tire, and I would not do it if I can't watch them.
