No, a 65 series tire has a much different diameter and circumference than a 75 series tire. Longshot gave you 2750 for the 75's, I would have suggested 2730, but that's a small difference that might be good "boundaries" on the values to try. If you've installed a 75 series tire, start with a value between 2750 and 2730.

If you are using 65 series tires, they are not nearly as tall (but they're "fatter"). Try something between 2580 and 2560mm.

You would enter these values in the Custom Options Menu - Tire Size.
