hyperopt

I am going to need a new set of tires soon, and I am planning to go from my current size of 225-55-16 to 225-60-16 on the first generation LS. Besides a small shift in the odometer reading, will there be clearance problems (eg. going over speed bumps) and/or ride improvement with 225-60-16? My factory original tire size is 205-65-15.
