Who uses Nitrogen in their tires?

I just bought a new three piece all leather sofa set. Cost me an arm and leg. But feels good to the touch. :) So does Connolly Hide Food work on home leather sofas? Will it give the protection and the necessary oils the leather needs in the home leathers? Thanks in advance. :)
 
Yes,



I have a pair of 1930's deco club chairs that get the Hyde Food treatment. It works great... just don't plan on sitting down for a few hours.

If you see valve stem caps that are green, the tires are Nitrogen filled.

I'm not sure I understand the advantages.

When a tire is low, where do you get nitrogen to re-fill the tire?

What are your thoughts on Nitrogen fill?
 
The advantage of the nitrogen, so I was told, is that the nitrogen molecule is larger than the oxygen molecule. It does not therefore leak through and out of the tire as easily.

We get our tires filled with nitrogen at the car dealer where we purchased the CR-V. In a pinch, though, you can just fill the tires with good ole air.
 
When I got my Highlander new the dealership had put nitrogen in the tires. It's only got 5k on the clock so I havent dealt with any issues yet. As far as advantages they say it is better for the tires as far as cracking & aging(something to do with size of molecules or something). The air pressure is supposed to stay more consistent which in theory leads to better fuel economy. Again nitrogen molecules dont expand/comtract as much as regular air in tires. I'm not sure I am sold on the idea.
the place where the nitrogen was put in the tires usually gives you free nitrogen if you have a leak.
 
Bill, the advantages to Nitrogen are many with primary being that the molecules are larger and loss through the tires rubber is much slower. Nitrogen also is less sensitve temperature changes. This is why race cars use it as their suspention systems are so sensetive. My new car came with nitrogen and I was excited right up to the point where I started looking for a place to top my tires off and keep them up to pressure. I have always been vigilant on this. Nitorgen seems to be a "profit" center for shops. When I called one and asked how much to top off my tires on occasion, I was told $29.95. Wow! When I asked how much to have my wife's car's tires filled with nitrogen, I was told $29.95! I top them off with a hand pump. I have no problem paying for the topping off, but I found this a bit much. I did not find many places to "re-fill" here in the Tampa area. Great idea, but you need to check out the pricing first.

At those kinds of prices, nitrogen probably doesn't make much sense. We get free nitrogen refills from the dealer where we bought our CR-V.
 
I wonder if I included filling off ones tires with Nitrogen when I'm detailing their vehicle........Not a bad idea to add to my detailing services......:thumbup:

I think that would only make sense if the tires are already filled with nitrogen. There's little benefit if the tires are filled with oxygen.
 
I see little to no benefit and it's hard to find a place to top off a nitrogen filled tyres in my area. Perhaps anybody with more scientific knowledge could explain it further?

I was excited to have my tires nitrogen filled back then but didn't see any significant differences between them. Plus it's hard to find a place to top up my nitrogen filled tires and it's pricey.
 
I dont have any Nitrogen in any of the 12 tires that we have, but I heard that Costco uses Nitrogen and if you buy tires from them, they refill forever or something...

I am getting new tires on the kid's car tomorrow at Discount Tire, which is also a chain, and will ask them if they use the gas or not..

According to Wikipedia, Nitrogen is already 78% of the atmosphere. So a regular fill of air into your tires is already 78% Nitrogen.

My tires started with Nitrogen, but when they got low as the temperature dropped ( yes, even with Nitrogen ), I took it to my tire place, and they just topped it off with air.

I think the main benefits apply to truckers and people who put a LOT of miles on their tires.
 
My opinion nitrogen filled tire is not worth the trouble unless it was filled for free. Nitrogen has larger molecules over air and air is made up of 78% nitrogen 21% oxygen 1% other gases. The benefits of nitrogen are less moisture ( as it eliminates it ), and with larger molecules it will not lose pressure through the porous rubber of the tire as fast as air over time. I have had a car with nitrogen filled tires and one without at the same time and saw no difference between the two in the four or five years of having the tires with nitrogen. I say stick with good old air and check and adjust your tire pressure regularly!

From my understanding the main advantage of Nitrogen is 2 fold:
1. Nitrogen is less sensitive to temperatures and therefore contracts and expands less so you dont have to add when the temperature gets cold. Also, for racing when you tires get very hot it helps manage the pressure.

2. There is less moisture in the nitrogen systems and therefore less corrosion of the wheels and stems.

There is no truth to leaking. The molecule size of both is small enough to leakout of a hole or bad valve. Unless you get it for free I would pass .
 
I just got my tires filled with nitrogen yesterday, for free, as I used to work at the dealership where I had it done.

The tech told me that Nitrogen is much drier than atmospheric air, which makes for less swelling and shrinking of the tire (more consistent tire pressure). He also told me that pure Nitrogen is lighter than atmospheric air, which yields all the common benefits of less unsprung weight.

EDIT: I dont normally get Nitrogen, but it was offered, so I said "why not?"
 
My TPMS light came on the other morning when it was very cold....pretty crazy how much the tire pressure can change with normal air in the tires depending on temp.

I had the same happen to my new Honda Fit with Nitrogen in the tires as soon as cold weather hit GA, so I'm not sure how much better Nitrogen is at keeping pressure as temperature changes
