Tire from new to legal limit of wear is 2% difference in the drivers favor. Oversized you are on your own. GPS would help to get a guesstimate of how much you’d need to compensate. Speedometers may be calibrated but for sure they can be tested for accuracy.
My GPS and speedometer are generally in agreement, although the speedo might be 1 mph higher at times. Both of our Fits now need new tires, but I have two sets in the shed, ready to go.
I hate buying tires. I always think I'm paying too much, and they don't really balance them.
