It may be in this thread somewhere, but I haven't found it in some quick scans, if so sorry. Has anyone filled their tires with nitrogen? Cost? Ride quality change? Does it maintain pressure in summer and winter? Thanks

 

haha dont waist your money its the biggest joke ever it doesnt do a thing

 

Well my dad has it in his 01 F250 V10 Ext Cab with a lift and 35s and his 03 TJ with lift and 33s...
He says the pressure stays the same, and rides a little better (only cause no pressure difference), cost was free to him cause he works with mainly Co2 but other gases. O and his tires seem to wear better (more even).

 

my buddy has it in his 4runner tires and likes it he says it makes for a better ride

 

my mom has it in her tires from costco, they ride alot better than the last set from costco that were filled with air

 

I just may try this so I can get out of changing from summer air to winter air and back again every year.

 

LOL

 

i have it in my rsx and believe me, it helps like crazy. the car has a very tight suspension and every crack on the highway used to hurt my back. it is noticable in a small car. i put nitrogen in my moms bonneville and didnt notice a thing except constant pressures.

 

 

I just got new tires from Costco filled with nitrogen, so being that they came that way its hard to say if they ride better, but it doesnt seem to be much different from my last set, and when I went to lunch today I noticed my drivers side front is already getting low, so
overall I am not that impressed so far

 

I was hoping nitrogen might smooth out my ride a bit. It definitely has that high-strung jittery ride found on a VERY taut suspension. My last ride was a ’92 4x2 Ranger, and it was SMOOOOTH…..I miss that.

 

I still don't get this trend for street cars. Air is 78% nitrogen already with around 20% being oxygen. All gasses expand when heated so I don't see the constant pressure argument. Moisture in the air can cause a problem if your tires get to 212 degrees F or more. This can happen in a race car and nitrogen is good for that application. Street tires don't get that hot unless someone is abusing them for a long time.

Moisture in tires can freeze at 32 degrees F and that could cause them to go out of balance when it settles out. That could be a viable reason to use dry nitrogen. The 20% oxygen in air could cause oxidation of the rubber from inside but that is unlikely. Oxidation of the wheels is more likely but how many wheels have you heard of that failed from oxidation on the inside of the tire? Oxygen and nitrogen molecules are similar in size and oxygen may even be slightly larger, since they make up about 98% of air, I don't buy the "holds air longer" argument either.

I don't see how nitrogen could cause a better ride or improve gas mileage. Pressure is pressure and as long as you keep it to what it is suppose to be it should make no difference if it is air or nitrogen.

I have a race car and know a lot of people that race with nitrogen in their tires. I can understand that but I still use air without any problems. I think one thing that allows me to use air is, I live in So. Cal. and the air is relatively dry here. That means I am filling my tires with fairly dry air and has a similar effect as dry nitrogen.

Maybe nitrogen has its benefits in tires but as a Chemist, I don't see many.

 

well as usual a very OPINIONATED and LOADED question. I have nitrogen in my tires. I have noticed a better ride with them and yes they hold there pressure. No variances with outside airtemps. The only thing that does suck is that if you do wheel a lot and air down your tires you cant just stop at a service station and refill with it. The nitrogen is supposed to make your tires run cooler thus for makes the tread life last longer, and since nitrogen IS lighter than air it does take a lil weight off but not enough to make a difference. You believe what you want and run what you want and the hell with what people on here say about it!! its like HIDS!!!! WHO CARES LMAO!!! btw i had it put it in my tires for $20 and thats for life!!

 

Rubber is a pourous material and oxygen molecules are smaller than nitrogen therefore nitrogen leaks less. There's a lot of advantages but that's the only one that applies to normal street use.

If air oxidized rubber, wouldn't the rubber on the outside, constantly being exposed to the atmosphere, oxidize?

 

taking the same principles from paintball, many people call high pressure air (HPA) "nitrogen". When "air" is compressed, it becomes enriched with nitrogen. Granted, HPA tanks for paintball usually run from 3000-4500 psi.

The air that goes in tires is mostly nitrogen anyways.

and the statement that oxygen is much smaller than nitrogen is false. the molecular size of N2 is 300 picometers, while O2 measures 292 picometers. That is less than 3%.

You contradicted yourself here.

Also remember that nitrogen is an inert gas .It doesn't react with other substances.

 

screw air or nitrogen. I just fill mine with Fix A Flat

 

I actually have done that before! Well, the tread was still good, it just had this air leak problem soooo...

 

Concrete fool, that schtuff never looses pressure and you don't never get no flats!

 

As an aside....
Exactly where does all the rubber that wears off tires go to?? The stuff doesn't just disentergrate or dissolve into the air. Shouldn't the sides of the highways be six inches deep in rubber dust? Hmmm.........

 

Rubber Gnomes
Similar to underwear gnomes but use a different processing facility.




edit
Can gnomes get high on nitrogen ?

 

When I had my tires put on they filled them with nitrogen when I told them not to, but they do seem to be a much smoother ride, that could be the tires as well though. Besides that I have not had them long enough to make any of my own decisions. I have heard its BS which is why i told them not to bother with it but I will have to wait to see for myself.

 

sure they can! lol

 

it is impossible that you get a better ride by using relativly pure nitrogen in your tires, as opposed to using atmospheric air, all other things being equal. pressure is pressure, that's all.

 

i'd use Helium......

less weight on the tires = less wear
