Tire pressure

[race735]

I have 2005 F350 DRW. I tow a Toy Hauler that loaded I am guessing around 10000LBS. My question is door says run front at 70 and rear at 60. Should I run what that says or run max pressure of tire? Load E tires

What is the max presure of the tires?

[race735]

They are 80

[Mack]

I would run what the door says.

I would run what the tires say. I don’t know why they put "recommended tire pressure" on the door. Even if you still have stock tires Ford uses at least 2 different tire manufactures. I run between 60-80 psi depending on if I'm towing or not.

[race735]

You run 80 on front and back when towing?

[colo_dually]

I run 75lbs all the way around, unless I tow heavy 10k or above. I'll drop the rear to 60-65 lbs empty before I hitch up. The rears under a load are going to have a higher pressure, that's why the door says 60 lbs on the rears so you don't have a blow out.

[Aussiekeeper]

Not towing, I run 35 lbs. on the rear, 50 on the front. Just replaced tires and they were worn very even.

I run whatever the pressure reccomendation on the tire is.

Tire pressure depends on the load and the tire manufactures limits. I suggest that with a normal load put a stripe side to side across the tread. Watch it to see where it wears off. In the middle pressure is to high. On the edges to low. It is the only way to determine the correct pressure regardless of load or temperature. Paint works best but chalk come off quicker.

My problem is that on my dually the rear pressure is seldom the same from tire to tire. Has anyone tried the crossfire, or Cateye tire pressure equalizer?
