tire pressure on tow vehicle
should I increase the rear tire pressure by 10 psi, on my truck's tires or leave at the suggested 35 psi that is shown on the sticker on the door jam?

I take a little different approach. My E rated tire max out at 80 psi. The light load pressure rating on the sticker is 45. I have 1200 - 1300 lbs tongue weight. The max load pressure recommendation is 70 psi. I measure the unloaded foot print, then hook up, fully loaded, and inflate tires to match that measurement. 65 lbs returns me to the unloaded foot print. Handles and rides good and does not overheat. On a warm day the tires gain about 7psi. The pressure listing for the front is 65 and that carries the heavy diesel just fine too. As someone else said, over inflating the tires is not really a good idea either
