Here ya go--
I have checked mine against 3 probes and find it pretty dog gone accurate, if you have good batteries in it.

Gas MIileage Data

A 1200 mile trip that I frequently make netter virtually the same gas mileage as when running air.

However, the tire pressure has remained at 40 psig.
 






I have never notice any difference in gas millage, but i have been using nitrogen in my tires for a year the place where i change oil fills then for free, and refill then any time i want in case of a flat tire.
 






I wish Mythbusters would test the theory of nitrogen in tires. I just see it as a gimmick to get your $50. May as well grease my muffler bearings or top off the blinker fluid.
 






The $20 that you spent to fill your tires with Nitrogen (which by the way...78% of the air you and I breathe is Nitrogen...) will never be made up by any of the theories that are stated.

The debate about Nitrogen vs. Compressed Air in tires has been around the block and back....as far as I'm concerned, if a shop wants to fill with Nitrogen for FREE...so be it, but if they are just trying to make some bucks on a hype concept, especially $20.... :rolleyes: .... forget about it. There are places (like Costco) that do it for free, as it should be.

About as much of a value as "bottled water".
 






I like the idea basically to help maintain pressures set as close to ideal as possible. I doubt any noticeable changes can be measured, but keeping the pressure constant is very important.
 






Nitrogen is marketing ploy. You will never get 100% nitrogen in your tires unless they mount them in a room filled with 100% nitrogen.
 






The people who race in SCCA use nitrogen around here.. The rims have two valve stems.. one to push nitrogen in, the other to vent the other gasses out.

they aren't in it for higher mileage.. They are in it becuase the pressure fluctuates less than with normal air.

BTW.. this is how it helps mileage.. but not dropping pressure as it gets cooler out.. Its not giving you mileage, its a crutch for people who don't check/adjust their tire pressure according to the season.

Ditto, I'm a mail carrier and it's a pain to be checking the tires all of the time. I do it more to catch nails and leaks etc.
 






Another use for a remote thermometer is to check the tyre temperature in 3 places across the tread to determine if your tyres are heating evenly.

This can show up incorrect tyre pressures.

A very useful no cost exercise to help with keeping tyre pressures correct and to assist with general running costs is the regularly check your tyres for stones and nails.
Stones can get stuck in the tread and as the tyre wears they'll get pushed into the bits of the tyre where the air is supposed to be.
 






I work on cars for a living and I don't know if I've ever seen any nitrogen filled tires that were NOT low. Maybe the shops around here, that do the nitrogen filling, don't know what they are doing. IDK, they are low when they come into my shop.
 






Those people are afraid to add air to them. LOL,

Never thought of it that way, but I believe you are right. :thumbsup: I have to say, I see the advantage of using N for high performance applications where tenths of a second are a lifetime. However I just can't get behind it for commonplace passenger vehicles. Ambient air is already 73% (depending upon source) pure Nitrogen. You mean to sell me on the idea that using 27% more N in my tires will make such a difference that it's worth my time to seek out a service station with a N tank or machine? I'm just not buying it.
 






It's about the greater amount of moisture that supposedly is in normal air, and the greater change in pressure with temperature changes.

I'd love to use N only for my tires, but that is a bit more complicated to do. If I had my vehicle's tire choices all set, and never changed anything, I'd find the time to do that with a tire change. It's just so easy to deal with normal air right now. There isn't enough proof of how much more tire life is gained with Nitrogen.
