Sizing tires?

I have a 2003 f250 6.0 and its leveled I wanted to know if I could run 315/75/16 on it? I have stock rims that are 16x7 and a 315 is 8 inches wide too so would like to know if they would fit with minimal too no rubbing? And also if ill get bad tire wear do too being 8 inches apposed to 7 inches. I have 285/75/16 now but look to small for me.

I have 2002 350 crew cab 4wd, I am running Nitto 305/70 16s on the factory rims. These rims are to narrow for these tires and the replacements have been ordered. To clear the front springs I have to run 1/2" spacers. The factory rims have 4.5" back space. The rims I ordered are Raceline Rockcrushers 16x8 with 3.65" backspace so I can get rid of the spacers on the front. For best tire performance and longevity the rims should be the same width as the actual tread or slightly less.

See I'm running 285/75/16 and they just look too small for the wheel wells. And the only difference with the 305's is there wider but if I get 305's will I need spacers?

You will need aftermarket rims to safely run 305's, watch the backspacing. If you get stock backspacing (4.5 inches) you will need spacers, just get correct spacing when you get new rims, they will need to be 4 inches or less to clear the front springs on full turns. You could just put up with the noise of the tires and the potential damage also.

Smoke is frowned upon on this site. Just a heads up.
