I’ve run that setup for over 40k miles now. At 60psi, you have a decent amount of gap at the rears, and you could drop down to 55 even for empty. 65psi when loaded and those tires are never going to touch. I had cupping issues on my front tires, thought it was balancing but I have Ford looking at the front suspension under warranty this week.
In some spots, my fronts are shot but the rears are still around 50% tread. So I bought two 50% tread matching tires off Ebay to put on the front before winter and keep on running. Can’t say enough good things about the mileage on these Coopers. I am going to mount the front tires without any wheel weights and use the Centramatic balancers on the hubs. People online seem to say those correct cupping issues.
