As Advmoto will attest driving on the Outer Banks beaches is some the softest sand known to man. My trucks suggested pressures are 65 front / 70 rear. At the beach I will start airing down to 35/30 with a light truck.Advmoto18 said:Depends on terrain.
Outer Banks National Seashore (everything from deep sand to hard pack) I've gone as low as 28psi in the rear, 30psi up front on my LRE Toyo ATII 295-16s on my F250.
Normal tarmac psi is 65 and up to 75 if pulling the boat with camper in the bed. 80 psi is max; embossed on sidewall.
The important thing to remember...
You must air up before driving normal highway (tarmac) speeds after airing down. PSI represents a given volume of air in the tire carcass. Not enough air and the tire will very quickly over-heat resulting in excessive wear and possibly failure at highway speeds.
I use this little pump to air up.
I would imagine that most places out west you could easily get by with 50 or so in my truck off-road.
