Yes. A 33x10.50 would fit better, but I've known lots of people that have run 33x12.50 on the factory rims, with some trimming and lift shackles. You need to extend your bumpstops as far as necessary to keep the tires out of metal. Of course a suspension lift would be better, but if this is all you can do right now, I say try it out and see how you like it.
