We need to extend a big
THANK YOU to Scott Ringler / WelderScott...
For years, Scott, at his own expense, has not only put on welding demonstrations with teaching opportunities, but has brought with him a large tank of liquid Nitrogen. He has filled numerous tires [cars, trucks and even motor homes] with Nitrogen at no charge to any of the recipients!
His machine fills all the vehicle's tires through a manifold to achieve equal pressure unless requested otherwise. He vents the air mixture in the tires down to 4 PSI to keep from breaking the bead loose or damaging the wheel. At that point, the tire is filled with Nitrogen to the desired pressure. Once this is achieved, the process is repeated.
He even did this process to my spare!
THANK YOU, WelderScott!
