Best tire pressure for 69 dart with P245 60R14

Just depends on what your plans are with the car ?
Cruiser, Street, Strip, Canyon ?
I would consider a 245 on the front a canyon tire.
Really depends on what your plans are with the car, then we could dial it in much better.
I plan on driving mostly street and road trips but not expecting to put on more than 2 or 3k miles per year... why the larger tires on front would be bad? clearance to fenders? mileage? My dart has a super power steering so that would not be an issue...
