Another TV tire pressure question

If you do not have the axle weights and inflate by their chart you are guessing and therefore SOL.

I've never had a any tire manufacture ask for weight or pressure info on a tire that failed . though it's been over 20 years since i have had a tire failure the questions never came up it was simply put on a new tire if under warranty .
truck manufactures put out psi based on ride comfort , tire manufactures put out psi ratings on expected load of said tire . since ford and chevy does not make the tires i keep my pressure based on the tire not the truck .

The maximum tire pressure molded into the sidewall of the tire does not take into account the pressure rating of the wheel it is mounted on or the rating of the valve stem that is installed.

Check with any tire manufacturer concerning recommended tire pressures and they will, without exception, defer to the vehicle manufacturer.


The day I decide that I am smarter than the engineering teams that designed and built my truck is the day I start building my own trucks (ain't gonna happen!).

I would be surprised to learn that an OE car company would mount a high Load Range tire ("D or "E") on wheels that are not capable of handling the tire inflation limits - Same for valves.
Not saying it can't happen just that I would expect the "system" capable of handling the tire pressure and load associated with the numbers molded ont the tire sidewall.


To be clear. the "max pressure" on a tire sidewall is really the Minimum pressure needed to support the states "Max Load".
Not all tires use the tern "max pressure" in the wording about Maximum Load.


Also the pressures we are talking about are the "Cold" pressure ie when the tire is at "Ambient air temperature" and not warmed up by running or being in the sun for the previous two hours.
