I really like the stock 17 wheels on my 2010 Sport.....I have BFG MT 225/75/17s mounted on them (Essentially stock Rubicon Tires). I want to go a bit bigger but would like to keep my stock wheels (Or better yet, pick up a pair of the same wheels in black) but I am not a huge fan of spacers. What is the largest tire I can run on my stock rims without having to put on spacers. I am not looking for much, perphaps the 33"-34" Range. Any Help Would Be Super Appreciated!

Thanks!
