proper tire psi,.transon ties,bow stop??

Nope. You can inflate the tire on or off the trailer. The pressure difference is hardly measurable.

I pulled my boat out of storage tonight (sad its so late I know) and my father and I got into an interesting discussion. We filled our trailer tires to the recommended 50psi, with the boat on the trailer. I suspect that if I had filled them to 50psi off the trailer, when they were on the trailer, with the weight of the boat and the trailer on it that it would be quite a bit more than 50psi even when cold.

So does anyone know if the recommended pressure changes whether the tire is under load on the trailer vs sitting on the floor of your garage?

Look up the ideal gas law

Having worked for Bob Walsh in the late 90's (former retired top level exec at Bridgestone/Firestone) I learned a few things about tires. Including the not published tire heating charts on trailer tires. I also learned how to set up tires for autocrossing based on temperatures across the face of the tread.

I advocate inflation of trailer tires to max PSI to reduce sidewall flexing, which reduces cording and heat related fatigue.

Having worked for a company that purchased many ISO containers of tires from Carlisle and Kenda, I can say I do not like either.

Your a wise man Scott. PSI is what determines the integrity of the tire....why would anyone jeopardize that?

Again...the chart from Maxxis. I guess they want their customers to jeopardize their safety.

It probably doesn't hurt to always inflate to max PSI but there are options if your tires are rated at much higher than your max load.

You got that right. Just suppose you adjust the psi to the load, what is going to happen when you hit that pothole or run down that road that is in desperate need of repair? I want my tires to be able to carry maximum load and nothing less. No one has given a strong reason why less is better.
