First off - regardless of what’s in your tire: the benefits of proper tire pressure are numerous. Keeping the correct air pressure in your tires helps them last longer, helps your car handle better, and could even help maximize your fuel economy. Under/over-inflated tires are more difficult to handle, and increase your risk of a tire blowout.
Nitrogen has become a popular choice for many drivers. The most notable advantage of nitrogen-filled tires deals with tire pressure, which is crucial for keeping your tires in good shape.
Now, there's nothing wrong with keeping your tires inflated with air. After all, drivers have been using compressed air successfully for years! Compressed air is easy to find and often free.
So by understanding the differences between the two can help you make an informed decision.

Nitrogen is kind of a gimmick for daily drivers -BUT- it's also very nice for tires that experience high temperature swings being it is more dense than air and therefore maintains a more stable pressure. I usually just fill mine at Costco since it's free and is actually very nice for trailers and Rv's or racing tires with extreme temperature swings. It leaks out much slower since it's denser than air and is nice for trailers that sit for a bit. It's why when you purchase an RV or Trailer, the tires are typically nitrogen-filled since they will sit for long periods of time.

@Coonazz791 3 месяца назад

Not only that, but for small trailers that have much smaller tires, those tires rotate much faster which causes more heat and will have much higher psi variations. But even with that, it’s just not worth the money unless you do have somewhere to add nitrogen for free like at Costco.

@neilduncan8657 2 года назад

I work on HVAC systems. Vacuum pumps and nitrogen are commonly used. When a tire is mounted, the air inside is 78% nitrogen. In reality the tire would need to be pulled into a vacuum (remove the air) and then the tire filled with nitrogen. If not, there still is other gasses besides nitrogen in the tire.

@YourHomeGarage 2 года назад

Totally agree that the tire will have other gases besides nitrogen if it’s not done properly. And honestly, it’s only a small percentage of people that would care deeply about this and it’s likely because they track their car or do other performance activities beyond the common driver. Outside of the “cycling the nitrogen” and heating up the tire and rim to get a better nitrogen percentage - I’ll have to look into the vacuum method. I would think the vacuum could create an integrity issue with the tire walls and then there’s atmosphere pressure to contend with. But you gave me something to look into - thank you.

@Vacublaster1 Год назад

@@YourHomeGarage Why, what is the point, just a lot of effort for no benefit.

@MicahFunk Год назад

I've given this some thought too. The tire couldn't have a vacuum pulled on it otherwise it would break the bead seal. BUT if the tire were placed in a vacuum chamber and had a nitrogen fill hose connected to it, a vacuum could be pulled on the interior and exterior of the tire so to not cause the tire to collapse under negative pressure. Then once the chamber is under total vacuum the nitrogen hose can be used to begin the fill process. Of course there would have to be a valve put in the fill line to switch from vacuum to nitrogen fill.

Correct ✅

I first heard of filling tires with nitrogen at age 11 (1966) when reading about the soon to be opened Montreal Metro using nitrogen instead of air in their tires. Being Intimately involved with bicycles, to motorcycles, to 4-wheelers, to 18-wheelers, thanks to your video, 57 years later, I finally understand what it's all about.

@YourHomeGarage Год назад

I used to live in Montreal (NDG) and used to love going on the Metro. It was smooth and quiet with those tires.

@TheCsanders Год назад

I have sold Nitrogen generators for many applications since 1993. I have sold over 1500 N2 tire filling systems as well. This video is a great explanation of both sides of the air vs N2 debate. My machines deflate and fill each tire twice to insure 96% purity in the tire. Machines are set at 99% purity on the outlet. If this process is done correctly you, you will see very little loss of pressure for 12 months. The reason car dealers like the product is that Nitrogen vs Air keeps the tire lights from coming on with temperature change. No one likes a dashboard light. In my opinion, $10 a tire it is worth it. Above that price it is questionable. The largest tractor trailer fleet in the USA Wal-Mart converted to Nitrogen a few years back reporting millions of dollars saved in fuel mileage, blowouts, and tire longevity.

@RESISTAGE Год назад

$10 for tire is a lot of money. not worth messing with. tire longevity? what? a whole lot of 5 mile difference? again not worth the trouble. been using air and will continue doing so for free.

@Coonazz791 3 месяца назад

Tbh, as a truck driver, Wal-mart didn’t save money because of switching to nitrogen. They lost money because their drivers don’t regularly check their tire pressures. I’ve been driving for 20 years and I’ve never had a blowout on my truck because I keep up on my tire pressure. Trailers are a different story because if multiple drivers before me pulled those trailers with low tire pressure and I fill them, then the tires are already weakened because of excessive heat cause by the heavy loads we haul.

@SkepticalCaveman 2 месяца назад

Since oxygen escapes the tire faster, then the nitrogen concentration actually increases over time. Even if you refill it with air, the air inside the tire has slightly less oxygen than the outside air.

@S_Paoli Год назад

My BMW dealer recommended filling the tires with nitrogen when I took delivery of the car last week. They gave me a discount and offered it to me at only USD$299. I declined because I prefer to flush 299 $1 bills down the drain on my own time. 😍

@Coonazz791 3 месяца назад

I wouldn’t think so, especially since tires aren’t made to last that long. Even if it did, the elements on the outside of the tire would be worse either way and deteriorate the outside of the tire at a faster rate. Long story short, if you have a vehicle with 10 year old tires on it, I would suggest not driving on them. Except to take it to the shop to get new tires.

@anthonyp6462 Год назад

I still didn't get the final outcome of this video. Is it worth it or not? For me, I just bought a 2023 Jeep Wrangler Rubicon JLU 4xe. It had nitrogen fill. Anyone who does even a modicum of off-roading knows that the tires need to be aired down to achieve a better contact patch and to achieve a smoother ride over obstacles. Why a dealership would put nitrogen into a tire that will be purposely deflated and reinflated many times over is absurd. Add to the fact that the dealership charges $100.00 for nitrogen fill is a crime. I told the dealership to either swap out the tires with air filled or I'd walk away from the deal. They threw the nitrogen filled tires in (seems it wasn't worth the "$100.00" loss to lose a sale). However, to your point about inherent tire pressure loss due to "sitting," a service advisor told me that they put nitrogen fill in new cars since they often sit for months before being sold. Having nitrogen decreases the amount of labor required to routinely check and reinflate air filled tires. And, he said, the dealership gets an added bump in profit if the customer doesn't question the cost of the nitrogen fill.

If you have anything that you have to fill with nitrogen or air more often, then you probably have a hole letting it out. The slight differences in how often you have to add air or nitrogen is so small, it’s a waste of money to use nitrogen. The only time it’s worth using nitrogen is if you’re racing and that’s only if you do it the right way.

@666dynomax 3 месяца назад

@sterlingpaul3004 3 месяца назад

You all realize why every major car dealership uses nitrogen in all the vehicles on their lot???? Ask any dealership manager and they will tell you that they do not want to be spending a bunch of time filling up tires. I can't remember the last time that I filled mine and they hold at 34 psi.

@motoarzan791 Год назад

THIS IS WHAT YOU DO. On a hot summer day (+25C), go to a freezer distribution warehouse (-15C). Check pressure at 32psi. Then put the tires in the freezer warehouse and come back a couple hours later and tell us what the new tire pressure is!!! You see, in northern climates of the US, Canada an Europe, a "40deg Celsius" temperature differential is common between an early "cold" spring day and a late "warm spring day in a short time span of only maybe 2-3months, and easily that differential from season to season. Not a problem if you check and adjust your pressure every month or so but in reality most people almost never check and adjust their tire pressure let alone even season to season.

@Coonazz791 3 месяца назад

So true. This can be an issue with desert driving as well here in the US. There can be a +30°F temp swing from morning to noon. As a trucker, I will run with a little less PSI in the morning because I know by the afternoon my tires will be much hotter than they were in the morning. Not only that, but I have to worry about some pretty dramatic altitude changes as well. It’s a pain to keep up with, but tires for big rigs aren’t cheap and a little bit of extra work can have a huge payoff in the long run.

What’s your view on nitrogen filled on EV tires. I see a good improvement on mileage after I filled with nitrogen.

@YourHomeGarage Год назад

Whether nitrogen or air filled really won’t affect mileage. Now nitrogen molecules are bigger than normal air molecules, so it is harder for them to leak out which means a tire filled with nitrogen will maintain air pressure longer. To get pure nitrogen in tires is a process, therefore a lot of garages and DIY’ers are just sticking with normal air - which in turn is rich with nitrogen. The main premise and goal with either one is to maintain proper pressure.

@DebraJohnson-ws7ni Месяц назад

So if you have a tire that has 80% nitrogen in it, that was filled by air and then you continue to refill or top off the pressure with nitrogen won't you eventually have a tire that will reach closer to 100% nitrogen if you are constantly losing the air molecules more than the nitrogen molecules?

@jman24961 Месяц назад

The kinetic diameter of nitrogen is only 5% greater than oxygen so I’m not really buying that there is a noticeable difference in pressure loss. You might have somewhat slower oxidation of the rubber from the inside but I seriously doubt it’s worth it until I’m shown data that demonstrate otherwise.

These same companies sponsor racing teams and force them to use it, giving this guy a stupid argument of "all racing teams use nitrogen" but in reality they don't use nitrogen that much in racing, they mostly use dry air. The only gas that really has an advantage is helium, but it leaks too quickly and is way more expensive.

So if you fill your tires with pure nitrogen, you're making almost NO DIFFERENCE to the tire. It sounds like an argument is being made that oxygen is bad for rubber. But there's so little of it in an inflated tire compared to the amount of nitrogen that would naturally get pumped into it, that if you're being told otherwise, you're being taken for a sucker.
