I have a question and need advice.. I have a new 2014 Keystone Bullet 285RLS TT with the standard load range D tires with 14 " wheels.. It says max pressure 50 lbs on the sidewalls. When I bought the TT , I had the dealer check air pressure in front of me and they were at only 40. Tech said that is fine. I insisted he fill them to 45 and he did. I used the TT only twice this year an tested them at 45. Tires and hubs remained cool to touch when I checked at rest stops. Should I be running these exactly at 50 at all times in hot weather and cool, or do you think 45 is the sweet spot. Would like to hear from Rv'ers with a lot of experience on this subject. Thanks!
Are you sure those are load range D ? Typically, LR D would have a max pressure of 65psi. Load range C is typically 50 psi.
Whichever is on there, if it were mine I would run the max psi that is stated on the sidewall of the tire.
