Tires and Dynamic vs Static Loads
Lots of debate on here about rear tires - SRW vs DRW, E rated vs 19.5.... But what about the front tires on a pickup with a heavy camper. The door sticker states the maximum load on the front and re...

Load ratings are listed as static loads because it's hard to measure dynamic loads...and will confuse most people because clearly their pickup doesn't weigh 30-40,000lb.
But ratings assume dynamic loads that the static loads generate when they are converted to dynamic.
The manufacturers already figured this out long ago.
This is why I find it funny when people freak out about someone only blocking a single tire on a dually MH to level it for the night...guess what the dynamic loads when that tire hits a nasty pothole are far higher than double the normal static load on the tire. As long as you pull up onto the block slowly keeping the dynamic loads minimal, there is no real risk.
