    You can go bigger. I think you'd only want to go to a 255 or 265 before needing spacers in the rear.

    Watch overloading. They are known for the dually tires squatting, rubbing together / pushing appart and popping wheel nuts.

    The dual tires rubbing together make it harder for them to dissipate heat generated and in turn can cause them to run hot and possibly fail. 265's is probably about all you can go without running some sort of a spacer.
