it will look great with the larger tires...
however, i -highly- recommend getting the bully dog tuner (or equivalent) before or right after if you go with the heavier tires. you'll notice a pretty big power loss if you go bigger. however the tuner will make up for that loss. i got mine off craigslist for $2-250 (can't remember now).
also, just to remind you what a before and after looks like, here's mine again from after i had the deluxe suspension lift installed with OEM tires to the bfgs...they fill up the wheel well nicely
