nitrogen in tires

Oh, and by the way....they used compressed air in automobiles for over 100 yrs. it works just fine. Even with TPMS

You're a "mechanic" ASE certified so you just fix things. I won't go into to much detail on how I know these things but its not from a mechanics stand point but from more of working with the engineers and testing. But you as the ASE mechanic can change out all the sensors when they come in. Hey one day you should go take a bad sensor on say a GM car and go drive it on the street around a corner at a decent speed and try and tell us all how stability doesn't work with it when it's using the brakes(not lightly either) tryin to keep the car straight. The face you'll make 😳followed by the thought ,"Dirt racer9x was right"😳Barking up the wrong tree here buddy. Stick to repairing them👍Ya Jeff keep on diggin were all watching little guy. 👍

You're either drunk,high,or just plain stupid! Maybe YOU should go get your family dr to let's say check you for a concussion or maybe a psychological test. Maybe find all those engineeres you talk abt an tell them u need help getting your cheese back on your cracker because it's slid way off! You're absolutely crazy!

Directly from GM..Here is what GM says about the use of Nitrogen in tires: GM's Position on the Use of nitrogen Gas in Tires (From GM's document #05-03-10-020C: Use of nitrogen Gas in Tires - Apr 27, 2010) General Motors does not oppose the use of purified nitrogen as an inflation gas for tires. We expect the theoretical benefits to be reduced in practical use due to the lack of an existing infrastructure to continuously facilitate inflating tires with nearly pure nitrogen.... Given those theoretical benefits, practical limitations, and the robust design of GM original equipment TPC tires, the realized benefits to our customer of inflating their tires with purified nitrogen are expected to be minimal. The Promise of Nitrogen: Under Controlled Conditions ...The use of nitrogen gas to inflate tires is a technology used in automobile racing. The following benefits under controlled conditions are attributed to nitrogen gas and its unique properties: • A reduction in the expected loss of Tire Pressure over time. • A reduction in the variance of Tire Pressures with temperature changes due to reduction of water vapor concentration. • A reduction of long term rubber degradation due to a decrease in oxygen concentrations. Important: These are obtainable performance improvements when relatively pure nitrogen gas is used to inflate tires under controlled conditions. Where does it state ANYTHING abt tire pressure sensors??

And for the guy that sent me the message abt corvette and Cameros linked stability control and tpms.....when tpms light comes ON. Stability control goes OFF via the traction control system. The 2 are NOT directly linked

The air we breath is 78% Nitrogen. If we air our tires with compressed Nitrogen, even after the purge process, the average maximum amount of Nitrogen is 90% per tire. Even with 90% Nitrogen in a particular tire, there is still 10% of regular compressed air. That 10% still has moisture content. It is the moisture that plays havoc on the air pressure gains/losses. It is more efficient to use dry air rather than Nitrogen. Thanks

Anonymous is correct. Even GM says the "benefits are minimal" of filling tires with nitrogen. Just make sure to keep your compressor drained and that u have a good dryer on the compressor and it should be ok.

Has anyone done any frictional testing between the two? What about atom size? Perhaps there's a leakage issue not addressed yet that proves beneficial on passenger cars. Perhaps there are other reasons Cup Teams and some NHRA Top Fuel teams are using nitrogen besides pressure build up. What the temp gradiant on a cup team car? Ambient to <300'f? Compare that to a typical dirt car of around 150'.

Many Cup teams also use nitrogen to power the air tools. It's common in off roading and trail riding as well. The benefits are a smaller tank that gets the job done but doesn't need extra equipment like an air compressor or electrical requirements to operate. Perhaps this is part of the equation.

Honest question dirtracer9x, are you an engineer? Not trying to start a discussion n using nitrogen or not just asking.

This thread surely makes it clear what the green or red colored rectangles represent.

If you want dry air in your tires, go to a auto body supply store or look online for paint gun bulb filters that screw on paint guns and install it right before your air chuck. These remove all moisture and oil that comes out of compressors. Been using them for 20+ years painting cars as i didn't want to spend several hundred to several thousand dollars on air dryers and oil seperators in my shop. Works for me. JMO

Excellent advice right here. Thank you for sharing.

Those do work great. I have them on my impact and air ratchets

[oldtrackchamp4x]

The ones I use are made by Motor Guard. My local Napa store has them as does Advanced Auto Parts. I'm pretty sure most parts stores can get them.JMO.
