This is a question that has been brought up many times before....larger wheels/tires for the IS300. To keep the speedometer and odometer from reading low, you would have to go to a lower-profile tire to make up for the larger wheel size and to keep the same outside diameter.
Some people don't care...they just do it anyway and live with the inaccurate speedometer....but that's a good way to get tickets. You end up going faster than you think you are.
