Tire sizes and speedometer mileage reading
I currently have 255/45/20 and 275/45/20 on my truck and the other day on round trip of 28 miles, my speedometer only clocked it at 25 miles in my truck. My other modern 2017 car with stock wheels gets the 28 miles as per google maps as well.
Would the size difference affect the mileage so much? Just wanting to hear any input on this.
