You're RPMs aren't measured at your wheel, they're measured by your crank sensor. He may be meaning your speedo gauge, but it the change will be insignificant if you go to the proper series of tire.

yeah you'll actually find calculator's on the web that will tell you how much you are off (speedo-wise).
