Help with tires 4th gen

Hello every one. I am new to the forum and have been looking at posts and photos for a few days. I have a 2010 Eddie Bauer with 18" wheels. I want a more aggressive look with out having to change the wheels. I want the tires to stick out some and be wider than the stock ones. Any help and or photos would be great. What tire size are you guys running? What about spacers etc? I also would like your input and photos for off road or mud tire choices. Been looking at discount tire and they don't offer much for my EX. Thanks in advance
