My 25 foot travel trailer front sits higher than the rear by about 2 inches. I cannot adjust the hitch any further. My rear tires on my Ram 2500 LONG bed are pressurized at 80 lbs. Can I reduce pressure to 60-70 lbs to even everything out or just leave it as it is? Does it really make that much difference? Thanks in advance.
Sure. No problems.
I would bet your TT hitch weight may be 900-1000 lbs plus your trucks 3000 lb empty rear axle weight = 4000 lbs on two rear tires or 2000 lbs per tire.
A LT265/70-17 E at 80 PSI = 3195 lb per tire in your case will have the tires wearing the centers with a rough ride.
Firestone load pressure charts on page
http://www.firestonetrucktires.com/pdf/Firestone_Load_Table.pdf for the above size tire shows;
45 psi = 2255 lbs
55 psi = 2595 lbs
65 psi = 2910 lbs
75 psi = 3005 lbs
I would add 5 psi per tire or so as a high sided trailer in strong side winds can cause more load on the lee side tires.
