They get some serious bounce, not necessarily the best thing for a 5th wheel full of stuff. Nobody says you have to be precise about it as long as you know you have sufficient pressure for the load you're carrying. If you don't know your load, and don't care to find out, then you're probably better off running max air pressure.Wild Card wrote:trail-explorer wrote:allen8106 wrote:

Thats not how it works.
The tire is rated for 4480# per tire at 110 psig. If you are not carrying 4480# per tire you are over inflated.
Edit
The 4480# per tire is just a number...i dont rmember what the exact capacity is.
That's how it works on paper in reality ST tires are notoriously cheap. Until I went to the top of the line tire like a Sailun. I had blow out issues. I want maximum capability and maximum margin therefore I air my tires to max. pressure.
I understand it is possible to over inflate your tires however my wear patterns are fine.
Trying to dial in load to tire pressure is pointless. We know the tires do not carry the same weight because the RV is not balanced that way.
Why bother filling the tires to some lower pressure in an effort to have pressure match load. If the load on each tire is different the pressure in each tire should be different as well if you truly wanted to match load to pressure.
I avoid all that nonsense and air to max pressure in order to get maximum capability and margin. Why derate the tire by lowering the air pressure? If I wanted a less capable tire I would have purchased some el cheapo vs. buying a Sailun and reducing the pressure to less capable ratings.
3 years at max. pressure so far no issues.

"Tire industry standards suggest - with strong wordings - that OE tires be inflated to the vehicle manufacturer recommendations - almost always what the side wall says."
IMO this is very much a CYA by the industry, both trailer, and tire. No one wants a lawsuit based on the statement that "They said my tires didn't have to be inflated that much", after the tire self-destructs because it was under inflated for the load it was carrying. Easiest, and probably recommended by the lawyers, to say "Fill 'em full".
Sez who? Why does it matter as long as my tires equal or exceed my GVWR. If I have 13,000 lbs. on three axles why do I need tires that can carry 24,000 lbs.? Please cite the regulation. And 6 "E" rated LT tires at 3,000 lbs. will equal my GVWR of 18,000 lbs. And more than equal when you figure 3,600 lbs. off for pin weight.
