Introducing an error isn't usually considered fixing.

No, it's as tele just said. The smaller the radius of the tire, the less real distance you've gone per odometer mile (which is based on a standard tire size).

If your tire rotates more times per mile, your odometer will overestimate the distance. So, a smaller tire = decreased distance.


First, I don't read tele. I don't want to waste my time on drivel.

Second, let's assume the actual miles per gallon are the same if the tire circumference is larger or smaller. The apparent gas mileage changes because the odometer measures distance based on tire rotation. If you drive 100 miles on new tires and your odometer is accurate it will show 100 miles. When the tires on the same vehicle have worn down, the odometer will read >100 miles when you drive 100 true miles. So the same true distance appears to be a greater distance. And if your true MPG hasn't changed, the apparent MPG increases.
Qazulight was right.
