    Proper air pressure for PWC trailer

    I have a single PWC trailer with 4.80x12 5 lug wheels. The trailer decal says to inflate to 60 PSI, and my old tires said the max PSI was also 60 PSI. However, I just replaced with new tires that have a max PSI of 90 PSI. So what's the proper pressure to use now? 60? 90? Something in between...
