Rear tire pressure
 

Hey everyone. I have a set of BFG Silvertown All Purpose 6-12, 2-ply tires on my 1968 CC 72. There is no psi rating on the tires. What's a safe ballpark pressure to run them at for mowing?

The guidance on the high flotation rear tires on the later Cubs was max of 15 with a minimum of 7.

Thank you!
