i do have to disagree with this because the high end pumps and recovery stations to give a micron rating as well as a mercury reading. and as far as the nitrogen in the tires is concerned it really depends on the application. i work on a lot of heavy equipment.....we max the tires out on the front of our trucks almost everytime they are driving. durring the summer months we have blowouts all of the time from overheating of the tires......we started using nitrogen in the front tires and the blow outs have gone away for the most part. your never going to get rid of all of the blowouts but we did see a big difference. and i will also add that nothing else was changed from the brand of tire to the people that were putting them on. so i wouldnt say that is snake oil.....but maybe not necessary for a light duty application where all your doing is going to the grocery store.

first of all- listen to me.
second of all -29" of mercury vaccum is where the micron reading begins
the **** they sell at wallmart is a joke.
nitrogen is the proper way to "clean" a system
most of the solevants you use to clean the system will likely break down the hoses,not be removed completly and break down the oil...ruining your compressor..or worse.
99% of the time a flush is NOT needed. that brown stuff in the pic is old oil,discoulered because of moisture in the system likely from a backyard tech
. flush's are required after "burnouts" and compressor failure.
blow nitogen through the system with hoses removed and if desired purchase the correct stuff to do a flush.
if you do not evacuate to a minimum of 1000 microns you are wasting your time.
there is a reason we do this and are trained to do it.
your method may work but the system will run at 40% 60%??????????????
NOT 100%

Lucas1, the po of my 91 d250 had someone put on a new comp., & dryer, evidently the only they could get to work was w/a direct hot wire. The comp., stayed on all the time, i did the bypass / therm., so i could turn it off & on in the cab.It does not cool at all& idon't know what gas they used , i'm thinking auto/ zone rentals???, do it myself.Good to know ya'lls tips ahead of time

[QUOTE=apwatson50;2977552]not trying to argue, just want to learn why would nitrogen fill stop tires from blowing out when fully loaded? Also did you fill the tires with a proper pump that pulls the air out of the tire then fills with nitrogen?
i didnt see the entire process of how the tires were mounted and filled. and i know that a lot of people are saying that this is full of crap--but on a fleet of over 300 trucks it did make a noticeable differnce in the cost the company has been paying for steer tires. for whatever reason the tires are running slightly cooler then they were running with air from the compressor. we know that they are running cooler due to the tire monitoring systems that we have on the trucks. everything has been the same except the change from compressed air to nitrogen. if you are looking for some type of scientific reason--i dont have one yet. but i will look into it more and try and get a better answer.
