In theory, you could do this, but you would really have to decrease the inflation pressure significantly......like to almost being flat!!! This will affect safety, fuel economy as well as handling from the standpoint of the sidewall being very bowed.

However, within a reasonable range, of say 265 to 295 tires, does it really matter? If it does, can you make up for the 265 tire by just dropping the inflation pressure like 2 psi compared to the 295 tire?
