The tag on the door jamb on my Ď13 dually calls for 75 psi in the front tires & 65 in the rear duals (all tires are load range E). This is my first DRW truck so I thought I would try these pressures out & see how it worked. Everything worked out great, both solo & towing my 16,400 pound 5th wheel. There was no noticeable squat to the rear tires with all that hitch (pin) weight on them & I checked the tire temperatures with an infrared thermometer during stops & I found that everything was fine.
The reason that I was so concerned about tire pressures is that a couple of friends of mine have DRW trucks & they insist on inflating their load range E tires to the maximum of 80 psi & they run this pressure whether towing or solo. I took a look at their rear tires & saw that the treads were all worn slick in the middle due to over inflation. This is also a very dangerous condition due to the reduced contact patch of rubber on the road which compromises wet traction & such. Anyway, 65 psi in the rear duals works for me with no problems.
