I did that with our F250. The speedo read 2% fast with the 245's. With the 265's it's just about perfect comparing the speedo to GPS. Same with my Prius. Went from 215/45 R17's to 215/50 R17's and corrected the speedo. Most manufacturer's calibrate the speedo to read a little fast as it's illegal for it to read slower than actual speed. Better to err on the fast side.
