Location: Delavan, WI | Hi Jason I met you at the last spring bay outing, take my opinion for whats its worth, I have been in the automotive industry for over 25 years. The max rating on a tire is just that , doesn't mean its what you should put in the tire its a manufacturer spec so people don't go above it and blow it out, I personally run my trailer tires at 35-40 psi, pulling a 19 ft ranger with tandem axles, if it were a single axle I would probably go to 45psi - it is my opinion running them at 50psi or above your boat gets a much harder ride over bumps, train tracks etc. thus putting more stress on trailer and boat, there is no need to run it at max press - most passenger cars nowadays run between 30-35 psi so that you get a nice soft ride, trucks is a whole different story |
