i have 35x12.50 open countries. empty i am runnung 62 up front and 55 in the rear. reason being, the front tires contact the road completely whereas the rears werent with 60+psi. i dropped the psi in the rear so the whole tire touchs. this avoids uneven wear. i got some chalk and rubbed it across each tire. the front rubbed all the chalk off but the rears left about 1/2-3/4 inch untouched on the outsides of the tires. havent towed with them yet but will probably bump it up in the rear. max for mine is i think 65psi.
