Speedo correction for larger tires?
When is it necessary to get a speedo correction for larger tires? I went from a 265/75 to a 285/75 both 16 inch. Would the height even change?

Check your speed with a GPS or smartphone with GPS and see how accurate your speedometer/odometer are with the stock tires. I did not realize it but with a camper load the actual speed was 2 MPH less than indicated thanks to the tires squatting and not being as tall. Only takes a 1/2" of squat to affect the speedometer accuracy by 4%.
