Tire fit question
 

I am looking to put bigger tires on my factory rims. I would like to know how big a tire I can fit that will not create any issues of rubbing. 04 F150 Regular cab xlt short bed 2 wheel drive. Size now is 265/70 r17 Is there a link that may be helpful? Any input or pics would be appreciated.
