    No one is saying you’re wrong. They’re just saying the price of the calibrator is not worth it for only 1 mph. Also they’re just explaining that your odometer is not gonna read more miles like someone else said. It will actually show you drove slightly less.

    I'm going to have the same problem with my truck. On my 2010 I have factory 265/70/18 and I'm going to have Lexus 20" wheels installed. The factory tire size for the 2010 Tundra with 20" wheels is 275/55/20, and according to the tire size comparison website, the speedo will be off the other way. If I'm going 70MPH, actual is 68.5MPH. I played with other sizes on the 20" that would be closer to the overall diameter to my current 18" wheels, but those tires are much more expensive.
