I also have a suggestion for tire makers:
Leave the "Max. Cold Pressure" figure off the tire sidewalls period, since more than half of drivers, vehicle owners, and even supposedly "ASE Certified" mechanics first look there for what to adjust tire pressures to. Not kidding, leave it off!
Instead, next to the maximum load weight in pounds & kg, inscribe: 'REFER TO VEHICLE MANUFACTURER TIRE PLACARD OR LITERATURE FOR APPROPRIATE COLD TIRE PRESSURES' on the tire sidewall, so as to remove any doubt.
The bursting inflation on tires made since the '90s is probably 50-100psi above any pressure the car makers are likely to specify anyway, so why list a Max. Cold number, since it's not near the bursting pressure anyway.

You are assuming everyone replaces their tires with OEM spec tires.
There is nothing wrong with running them at the sidewall pressure. Generally speaking a little over is better than low anyway. They are figuring, usually correctly, that most people don't bother checking them ever.

My question was in reference to UrbanAdventurer's contention(post #67) that it was OK to run tires at the maximum pressure listed on a tire's sidewall, vs. the pressures listed on the vehicle frame or owners manual.

No matter who services my car, they always over inflate the tires
