Hey Bill, maybe you can clear this up for me. I’ve heard that before, the part about passenger tires and trailer tires. I’m my mind a failure of a trailer tire is a heck of a lot more dangerous than one on the car. I’d hate to be towing a trailer at 70 mph and have a tire separate from the rim. A car and trailer whipping around is a bunch more trouble than just trying to keep a car inline.
So as I’m typing I’m answering my own question as I often do during composition. It’s not as I was thinking, that is in the ability of the tire to carry the load with out failing, but in the handling because of the construction and compounding differences. I found this online and it best explains those differences.

Ok, thanks Bill, you’ve gotten me back on track once again.

Jon, did you get your tires from Coker? I put a new set of Power King, Premium Super Highway bias plys on my 3600 when I first brought it home. Every time I drove the truck for the first 10 or 15 minutes at the beginning of a drive they would literally shake your teeth out. At times I thought it was actually going to shake something loose in the front end. Worst riding tire that I’ve ever had on a vehicle, the switch to Cooper Radials was the best thing I’ve done to the truck since I bought it. Not completely original and I had to update to a ’70 C-20 rim but 95% of the people that see them can’t tell the difference.
