Ive got a new 2012 F250 with the 20" option - 275/65R20. This rim is 20x8 from what I can gather. I'm wanting to get the XD Badlands, but these are 20x9's. Has anyone put these on the stock tires? Will I run into any issues?

Most of my driving is highway, and I really dont want to have to purchase a new set of tires to go with the rims when I have perfectly good new Michelin's on my truck. Hoping that this will look good as well, as I've only seen upgrades on tires too with these rims. Suggestions or opinions would be appreciated.
