well I think it may be best to do an ana-lysis on how much it really changes the braking performance of the vehicle (assuming that's what you are concerned about)
For illustrative purposes, it would be best to compare the energy stored in a stock PW with a small load in the bed to a large-tire PW with no load. Use the math to back-calculate the "equivalent load" in the bed of a stock PW that makes it comparable to a large-tire PW. It is a very simple procedure and would provide a pretty intuitive comparison and perhaps alleviate your concerns.
So for example, I may find that the braking perfomance of a stock PW with a 400lb passenger is the same as a large-tire PW with a 160lb passenger. This is just an example of the type of answer that would be very easy to produce.
If you know the geometrical properties of the 11.00R16 and 9.00R16 I can do the math quickly and let you know how it shakes out.
