need wheel info

[mattc]

I am looking to buy new or used wheels for my 05 canyon off road in the near future, does any one know what would be the biggest wheels and tires I could put on my truck without having to do any cutting or lift kits? I am going for the wide look. Also anyone know of a web site where I could buy some decent wheels at a good price? I would really like some 17' or 18' black bullet holes with crome bead locks. What do you all think would be the best looking tires...pro comp ? Bf Goodrich? ETC..
