    It'll depend on the tire brand and model. Mine is max 50psi cold.

    I have a 920 on Goodyear Endurance tires. The tires say 65psi max. I run 55psi with no issues in 2 years.

    Trailer tire PSI is typically determined buy load class...load class B 35 psi...load class C 50 PSI and load class D 65 PSI. There should be a sticker on the trailer that gives the recommend size tire for the trailer. It may or may not say what load class tire is recommend. If the trailer does specify a particular load class tire and you use a different load class tire than what the trailer recommends then go buy what the tire you actually have mounted suggest for recommended tire pressure.

    run your tires at rating. If they say 50 psi it is a load C and has max speed rating of 65mph on all that I've seen.
