No. In what context did I give that impression?
Maybe it was the 20% reserve with replacement tires. Remember, the tire pressure listed on the tire sidewall IS NOT a recommendation. It's the amount of cold inflation pressure needed to get the maximum load capacity from the tire. That load capacity is also on the tire sidewall.
I often say this and seldom miss the chance. Tire manufacturer's have NOTHING to do with setting the recommended inflation pressures for OE tires. That is exclusively the responsibility of the vehicle manufacturer. It is supported by the tire industry in a statement very similar to this one. Replacement tires MUST provide a load capacity - with inflation pressures - equal to or greater than what the OE tires provided.
Vehicle manufacturer recommended cold tire inflation pressures for Original Equipment RV trailer tires are almost always going to be an inflation pressure equal to the tire manufacturer's cold inflation pressure found on the tire sidewall. Replacement tires with more load capacity than the OE tires will normally require more inflation pressure to gain extra load capacity reserves. Such replacement tires - especially those with a higher load range - will normally have maximum inflation pressures higher than the OE tires had.
