So...what you're sayin' is: I'm a chump- right?
Answer me this:
The maximum pressure for the tires
on my car is 40 pounds. The tires
can be used on many vehicle brands/types/weights besides my own. The tiremaker advises me to go by the carmaker's recommendations per pressure. My carmaker says 26 pounds, cold.
On other vehicles, pressure recommendations for the same tire
will differ, never exceeding the maximum pressure allowed by the tiremaker.
If not load/weight, what (primary) factor governs the carmaker's pressure recommendation for each vehicle?
