what tire pressure you guys running on your 35 toyo mt's been playing with the pressure trying to find the best all around running psi.

 

I can only offer you general advice but:

Take a grease pencil or some chalk and draw it across the tread. Then drive the truck a head a bit and see how the chalk wears.

To get the best mileage (life & mpg) you basically want to air the tires up to the point just before the chalk starts to stay on the tread at the edges.

So if at 45 psi you see chalk left on the outer edges then lower it down to 42 and try it.

I bet you'll be around 35 psi or so.

 

around 40 on mine.
