Hi, if your Towmax tires are load rated "D", then they should be inflated to 65 psi cold. Running the tires with lower psi will make them run hotter and shorten their life.
I just dumped my Towmax D's and replaced them with Maxxi E's, which are rated at 80psi. The sticker on my fiver says 65 psi, but that sticker assumes that D's are installed. I run my E's at 80psi.
