Tire Pressure - MAX vs DATAPLATE
A LOT of replies to tire threads recommend running the trailer (and I assume also car/truck/motorhome) at sidewall max psi instead of the dataplate psi. Why? My trailer tires have a max psi of 120....

Benefit is (slightly) improved fuel mileage. But the cost is uneven tire wear leading to early replacement (not an issue on RVs which generally need new tires due to age long before the tread wears out); rough/bouncy ride (again, not so much an issue on a vehicle in which nobody is present and "stuff" is all tied down); slightly poorer traction/cornering ability; and slightly higher blowout risk.
Bear in mind that there is controversy over the issue BECAUSE the differences either way are relatively small.
