tire pressure

[deshet]

I bought a trailer tire the other day for my cargo trailer and I asked the guy about tire pressure and he told me they are 85-90 psi for trailer tires.

I was surprised. And I asked him again. He confirmed that it was 85-90. He said you don't run them like car tires or you will wear them out ever three months.

Still sounds crazy to me.

I know one thing you should not run car tires because they are not setup for the same load as trailer tires.

thanks
