Just tryed the search but it came up empty. Has anybody switch to using nitrogen in there tires. And if so did you notice better mpg or anything else.

Thanks.

 

Yeah, I think the Search function is taking a vacation. It's come up time to time. I use it in my tires religiously, but I'm very strict on the exact amount. I put it in at a .78084 to 1 ratio...

 

I keep mine at .780835

 

Can u explain the numbers. I thought it was just straight nitrogen.

 

i've been using it in mine since i bought new rims in tires. not sure of the mpg thing though since its all i've used since i have bought the truck. my rim shop does it for me so iim not sure of the levels either.

 

Makeup of our atmosphere:

Gas Volume Nitrogen (N2) 780,840 ppmv (78.084%) Oxygen (O2) 209,460 ppmv (20.946%) Argon (Ar) 9,340 ppmv (0.9340%) Carbon dioxide (CO2) 390 ppmv (0.039%) Neon (Ne) 18.18 ppmv (0.001818%) Helium (He) 5.24 ppmv (0.000524%) Methane (CH4) 1.79 ppmv (0.000179%) Krypton (Kr) 1.14 ppmv (0.000114%) Hydrogen (H2) 0.55 ppmv (0.000055%) Nitrous oxide (N2O) 0.3 ppmv (0.00003%) Carbon monoxide (CO) 0.1 ppmv (0.00001%) Xenon (Xe) 0.09 ppmv (9×10−6%) (0.000009%) Ozone (O3) 0.0 to 0.07 ppmv (0 to 7×10−6%) Nitrogen dioxide (NO2) 0.02 ppmv (2×10−6%) (0.000002%) Iodine (I2) 0.01 ppmv (1×10−6%) (0.000001%) Ammonia (NH3) trace


In other words, when you go to any air pump, you are getting almost 80% Nitrogen.

The theory behind putting 100% Nitrogen in the tires is because nitrogen molecules are larger than Oxygen molecules. Supposedly minute cracks and imperfections in a tire will leak Oxygen more readily than Nitrogen. They also do not contract quite as much when cooled.

So, on paper anyway, the tire stays at the PSI you put in it and you don't have to add when it gets cold. Obviously, a full tire gets better gas mileage than one that is running low. I know people who have 100% Nitrogen and they still had to add in the winter.

IMO, a waste of $ or a gimmick for those who are too damn lazy to check tire pressure and adjust accordingly from time to time...

 

i dont even know if i have nitrogen in my tires at all..i just bought the truck bout a couple of months and was just curious on if i had it in mine or not. Reason i say that is that is that there is some blueish green air dust cap on my tires and i thought that maybe those were put on there for a reason. Is there a way to check to see if I have nitrogen in my tires?

 

Do you live on earth? If yes, you have nitrogen in your tires. This is pretty much the jist of the replies you are getting. In regards to whether you have pure nitrogen or not, I dont believe there's any way to determine that. My truck had two green caps when I bought it, and I'm certain it means nothing.

 

we run it in the race car tires. the only real differance that we have ever noticed is the tires don't grow. tire temps arn't at high so the tires don't wear so much because they arnt heating up as much. as for normal every day driving its not going to help anything besides tire wear

 

I don't have it in their now, but the truck needs some new shoes soon so I'm planning on picking up some nice rubber over the summer and I think then I'll have the initial fill done with 100% nitrogen and see what happens. I figure with 20" rims a good set of tires (leaning towards the TOYO open country A/T) are gonna run me 1500ish so what's another 50 bucks to get nitro fill.
