No matter the type or design tire used on our trailers, they still have to have the proper air pressure to operate within it’s advertised parameters. According to a NHTSA survey, under inflation is the most abused condition found when inspecting tires used on our highways.
So let’s ask the engineers some questions. I’ll kick it off with these.
What is the origin of the load inflation charts found on the internet from various tire manufacturers?
Are they written for the public at large to apply them as they see fit?
Or, are they essentially provided as a tool for vehicle manufacturers and tire installers?
We see lots of information about getting our trailer’s to the scales and getting each tire position weighed. Then we are told to air the tires to the highest weight on each axle as long as it’s within the tires operating parameters. Isn’t that being counter productive? Doing that provides zero load capacity reserves for the heavy tire. Besides that, the procedure may not apply to all trailers because, we are already told by the vehicle manufacturer to air our tires to the maximum allowed via the tire placard.
