Tire inflation pressure
I have seen it posted many times to inflate tires 5-10# over rv listed tire pressure. Why would you do this?

Depends on what you mean by "rv listed" tire pressure.
The cases where people are suggesting adding 5-10 lb is when:
1. Motor home is weighed at the scales getting the 'front' and 'rear' weights.
2. Access to a four corner weights are not available.
3. The tire manufacturers chart for 'minimum' is used to determine tire pressure.
In this case, since only the front and rear weights are known there may be a variance in the 'side to side' weight.
Since the tire pressure should be determined by the heaviest side of an axle, 5-10 lb may be added to allow for side to side weight variance.
NOte: adding pressure above the RV label or tire sidewall is NOT recommended.
