I would check the tires for ratings. If you go to 80 psi on a rubber valve stem you will shoot it out on the road. A load range c tire doesn't seem adequate for that vehicle. I just double checked it and it should be on E's for the size of that vehicle with metal valve stems and 55-80 psi.

I am going to put my e range tires on it in the near future. I will also pick up some metal valve stems. The previous owner used it for hauling hay and used whatever tires he could get. I have been EOCing the snot out of the truck and it works nicely. Turn off key, put in neutral. To start: Turn key on and put in high gear and nudge the clutch. Works like a charm. I want to mount a kill switch on the stick so I can cet out a couple of steps. I have been hauling lumber for Wayne this week so The numbers may be down a little but that will give me a good average for what the truck does. I filled it to the top of the tank today and will see what this tank returns.
