    Correct Tire Pressure????

    I've got a 18' fiberglass bass boat with a 150 Johnson on it. I could not but estimate the weight as 1500 plus #'s and am concerned on the correct air pressure. I've got ST175/80R13 6 ply tires on it. What should i run for proper air pressure to ensure longevity? Thanks Guys!

    Max cold pressure. You should have load range C tires and fill them to 50 lbs.

    Yup, it's a load range C and i have it at 35 ---I will fill to 50#'s on Sunday; I'd like to say Saturday, but it's supposed to be wind gusting to 25 MPH, so i'll go fishing Sunday- Thanks Mike!

    Most load range C tires I have seen take 50lbs, Yours might not... Just fill them to max capacity it reccomends on your tire.

    They don't always look low because the sidewalls are stronger, so check them often.
