Read the sidewall. 110 PSI COLD. Tires do not blow out due to over inflation, within reasonable limits. A tire that is not damaged can hold 150% of the cold pressure easily. I've inflated tires to more than double their cold pressure to get leaking tires to hold air long enough to get cars to the junkyard. Tires blow from HEAT, when the temperature of the tire approaches the cure temperature or cap cure temperature, the tire comes apart. Running the tires under inflated like you are (and 110 PSI HOT is underinflated) makes them run way hotter. If you need qualifications behind my statement, I am ASE master certified both in automotive and medium / heavy truck. However this information is readily available in tire literature.
Why trailers almost always have auto inflate on tires, but trucks almost never do?

So why do tire manufacturers come out with tire inflation tables, if your supposed to just cold inflate what it says on the tire. My steer tires say 120 cold. But that is for 14300 lbs on that axel and I don’t run that heavy on the front. I’d go with what manufacturers recommend, not what your mate says.

I know. I was just saying just because it says that on the sidewall doesn’t mean it should be pressured up that high.

This is an interesting read......if anybody is so inclined. I enjoy technical articles.

The Halo inflation system has been mentioned. Here is the link: $1540 for a tandem axle tractor with dual wheels.
Apparently reliable technology been around for several years. Clearly the marketplace has not embraced them for reasons unknown;

If you look on the door plate, it tells you the pressures it came from the factory with the proper tires, as well as the trailer plate. So mine says 110 steers. 95 drives. And 90 trailer, which compared to manufacturers recommended pressures it’s pretty bob on.No Exit and Dockbumper Thank this.
