Air in tires

Originally posted by lostagain I use air from Neptune.  It's is mostly helium and hydrogen so I am able to lower the weight of the trailer a little and the tires float better.

UPS charges must be astronomic.

Trailer tires are much different than passenger vehicle tires, and should be run at the max pressure.  Which would be different if the pod tires are changed to a different load range.

Also, on passenger vehicles, the sticker on the car is the proper pressure only when dealing with the oem tires and stock vehicle weight.  If any of the variables change, then the proper pressure also changes.

I have a 2016 truck with Nitrogen in the tires, I also live at the intersection of 3 major interstates, 65, 24 and 40. I have a factory installed TPMS. I will tell you my pressure varies with heat and cold, not as much with air but still measureable. Blow outs are not solved by what fills the tire. Blow outs can be blamed on over pressure, but a major heat source is under inflation. OTR trucks can have both regrooved and recapped tires, only buses are regulated to have virgin tires on the steering wheels. The material you see on interstates primarily comes from tire failures from OTR vehicles. Granted it can increase during summer months as the road surface has more heat. Nitrogen has nothing to do with this. Once again, air, what we breath and fill tires with is 78% Nitrogen.
