Personally, I like 12" wide tires. I have 285/75R16 on my superduty, which are about a 33/12.50R16. Just remember if you go much bigger, that unless you have fender flares, the wider tires will throw mud and rocks up the side of your truck. If you look in the phone book, it is listed under Gateway Tire off of rt. 747 in Tri-County.
