Re: Air pressure?

I test contact by either wetting tires or run through a wet spot. Then I observe the track it leaves. On dry ground you can wipe a tire down and roll it over the dry ground and observe the tire. I run 55# in my 285/75-16 Goodyear Duratracs on my '72 K2500 and they lay flat across the tread mounted on 8" wheels. The tires are load range E and call for 80# cold pressure. I run relatively light to pretty heavy and they ride nice an stable with weight while not too hard when bed is empty.

You have to go by vehicle vs tire rating vs use with a little bit of tire type/brand mixed in.
