tires and nerf bars
 

Ive checked a few of the pages and couldn't find any previous post, so I apologize if this has already been covered. I have a stock F250 with the off road package and super cab. Stock wheels are 17" and I found a good deal on a set of 18" wheels and tires. I believe stock tires from Ford on 18" wheels are 275/70R18 (size I'm getting) and the wheels are 18x9. Can anyone tell me if I will have any rubbing issues at stock height. Also I am looking for 4" round Nerf bars in black. Can anyone recommend a good set. The best ones I've found were from Aries but I can't find them for a super cab, just regular cab and crew cab only. Thanks for all the help.
