7,000# dry weight or GVWR?

What model trailer are you towing?

Weight your trailer and truck combination fully loaded with all passengers and gear for camping on a certified truck scale. This will weight your steer axle (front), drive axle (rear) and the trailer axles. You can then use the tire inflations charts from your tire manufacture to obtain the correct air pressure for the tires under load. You may need to go to a tire store to find the inflation charts or on line if they are published for your tire. The air pressure may be less than the placard calls for; the placard information is the maximum air pressure that will support the maximum load on the rear axle.

Check my truck listed below. I have tires that max wt.is 3750 lbs at 80 psi. I run them all at 55 with empty truck. I needed to go to 65 front 80 rear with a slide in camper wt. of 4400lbs and towing at 3800lb boat. Now the trailer I have has a hitch wt. of 900lbs scaled/loaded. I have left the tires at 55 for several short trips, I think that they should be alittle more air thro and will try 60 than 65 cold psi and see if anything is different. At 55 psi they are not flattened out or cause rear sway. Check the wt. as said by others and try afew different settings, look at the tries to makes sure they are not showing signs of under/over pressure.
