Best tire pressure for 69 dart with P245 60R14

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...

There will be a thousand opinions on tire size preference on this site. My suggestion is to search the site on "tire size" or "show your rims and tires". There are literally hundreds of pics,opinions, on the thread. I can't choose a tire for you, because our tastes are way different.
I prefer a 215/70-14 or even a 205 on my cars. But that's just me.
