Thanks guys! 285's would be the largest I would go, so it looks like I'll be ok with the set-up I have. I currently have the stock running boards, but hope to get some "rock rails" and get rid of all of that plastic trim at the front and back of the running boards... that looks like it'll clear out some space at the rear of the front wheel wells, too.

Thanks again!
