re: Nitrogen in tires?

um... nitrogen turns liquid at like -300 F... as it warms up it turns to gas

THANK YOU!
Not only did your experience show you there is a benefit but there is scientific proof.
Free air or free nitrogen... how is this is hard choice?
Should you spend $50 filling up no! but that has nothing to do with nitrogen, that's dirty businesses!

ignorance is lacking knowledge, i can provide you with some technical data sheets explaining the difference in air compressor oxygen vs nitrogen in tires if you would like. there has been some long winded studies on this if you understand GLS and OLS regressions... just in case you want to educated yourself and be less ignorant

Yeah, some businesses just take advantage of people. Wholesale on nitrogen is about $.17 per cubic foot. 4.5 cubic feet will be around 10-15 psi per tire. at 30 psi * 4 tires you need 36 cubic feet = $6.12 for all 4. Charging $10 for a full fill up from new tires or $2.99 to top off and your still making a profit.

yes but nitrogen is a dry gas, oxygen carries humidity which expands when heated...
and they aren't the same, i think its a 1.4kj difference which isn't much but pure oxygen is better then nitrogen with heat, but then you are still paying for someone to compress it properly (and im not talking about a simple air compressor) which costs more than nitrogen but leaks through the tire faster so your still at a loss.
Nitrogen is better, its really just a conversation about how much gain do you get for how much you have to pay.
