Snopczynski Posted May 15, 2007 Report Share Posted May 15, 2007 I am a technician for a living. The only advantage that nitrogen in your tires offers is reduced internal rotting of the tire. I personally have never ever seen the inside of a compressed air filled tire rot though. Quote Link to comment Share on other sites More sharing options...

I suppose you really need ot have seen the film Orgazmo to appreciate that. Use it or lose it buddy...no Viagra...yet...LOL... (My ex girlfriend's grandpa...like 85 years old...used to always walk around with his zipper down. Yeah, alheimerz was setting in. He'd always say...what can't get up, can't get out.... For some reason it's funnier when an old timer says shit like that...) Sorry firehead have taken another topic way OFF topic...once again.... :biggrin: Quote Link to comment Share on other sites More sharing options...

I wouldn't say that's the only advantage.............as there are others, but the cost-benefit of any if them is not very good. :thumbsup: Quote Link to comment Share on other sites More sharing options...

jayzx10r Posted May 17, 2007 Report Share Posted May 17, 2007 Actually I heard that helium filled tires reduce unsprung weight!!! And we all know that 1lb of unspring weight reduction = 2.67lbs of additional thrust!! :biggrin: Quote Link to comment Share on other sites More sharing options...

Satsol67 Posted May 18, 2007 Author Report Share Posted May 18, 2007 Looks like I will find out if its bs or not. While I was waiting for them to put my new tires on I noticed on their sign that they used nitrogen so I walked over to the guy that was putting them on and asked about it. Turns out that they use nitrogen for all their tires. He was telling me that the main reason for it is it helps with the life of the tire. Being that with the nitrogen in them they will only reach a certain temp. Which make since. He also said that you might get a few more miles to the gallon but its really just to help get the full mileage out of the tire. Its filled with 65% nitrogen 35% air and the only way it will leak out is if you have a rim or valve steam leak and of course a puncture. It wasnt any extra charge so what the hell. Time will tell.

I hate to break it to you, but all tires leak. Most of the time at a rate of what I previously mentioned in this thread. Quote Link to comment Share on other sites More sharing options...

Hi. Mr. Buzzkill here. If Nitrogen doesn't expand as much as atmospheric gas, the result will be a lower operating pressure once the tires have reached their operating temp. This will LOWER your mileage compared to a tire that is run at a higher pressure...all things being equal. A harder tire = less rolling resistance = less contact = BETTER mileage!!. First. Understand that the tires generate heat because the rotational forces induce friction generated from rubber/asphalt contact and the torsion rubber goes through to maintain contact over varying terrain. Second. Friction generates heat. Heat has the effect of expansion on any gas...some more than others... Third. Tire pressure specs are determined with the understanding that compressed "air" will be the medium used. If you want to use nitrogen, you would need to increase the initial pressure to end up with the desired operational pressure...because using Nitrogen will have you at a lower pressure at OpTemp!! Finally!! The use of Nitrogen filled to the tire manufacturers spec for atmospheric gas will net you LOWER MILEAGE!!! than if you used good ol' smoggy air at fill up!! To sum up my rant... Because Nitrogen expands less relative to temp increase, you need run a HIGHER initial cold pressure...which will give you better mileage(because of improved frictional coefficiency) DURING the time it takes for the tire to reach it's normal operating temp. This point in time is your MPG increase over "air." Once the tire reaches OpTemp, there is no improvment over "air," if ultimately final operating pressures between the two are equal. If you do not increase your initial pressure to factor in the different characteristics of these 2 gasses, you will LOWER your MPG because your tire will never reach the desired pressure and resultant "Hardness" (durometer rating) the engineer envisioned when they spec'd your tire design. An example based on numbers I'm pulling out of my ass: 1. Nitrogen filled: Tire filled to 35PSI. Operated for 15 minutes-tire pressure is 38PSI. 2. Air filled: Tire filled to 35PSI. Operated for 15 minutes-tire pressure is 44PSI. 3. Nitrogen filled: Tire filled to 40PSI. Operated for 15 minutes-tire pressure is 44PSI. The 44PSI tire will roll easier than the 38PSI tire. The tire engineer designed the tire for 44PSI operation. So I agree, using Nitrogen has the potential to give you better MPG...but ONLY if you adjust for it. Dude, you adjust your jetting for elevation/temp...this is no different!! Did I mention I like Red Bull too?? :sweat: I need to get back to work!! Hope this helps. Jay From SanD.

XxMeltIcexX Posted May 19, 2007 Report Share Posted May 19, 2007 lmao, red bull anyone?? I got a nitrogen tank sitting in my shop for the buggy shocks, i'll try and see if i can regulate that low and try em in my tires (little shit pops off the shocks and sounds like someones shootin at you). Nothin better than some old fashioned science projects... :biggrin: Quote Link to comment Share on other sites More sharing options...
