What size are the rears? Are they 18.4R30s? If so, you should be good at 15psi. If you are hauling hay bales on the back, you might want keep it at 18.
I have 16.9R30s on mine and I put 17.5 with the HX15 cutter on the back as it is very heavy. I will drop it back down to 15 for all the other things I use it for.
