Re: Tire Pressure

I would use the vehicle spec from Packard when using bias ply tires unless the tire company says otherwise.

Coker specifies its own tire pressures for radials so I would use that for their tires.

I would not use the maximum on the sidewall. For one thing running excessive tire pressures beats the daylights out of the suspension and frame.

For after market radials that don't specify the same way Coker does I guess I would look for a vehicle with similar weight and axle loading and start with that or 75-80% of the sidewall max as a rule of thumb.
