Where can you find the correct wheel sizes for speed sensor 2. Curious if auto works best or manually entering the size? What degree of difference is normal compared to just using GPS?

Do it oldschool. Make a chalk line on the street, put the wheel valve down on that line, walk one full rotation, do another line and measure. Or take a tape measure and wrap it around, that's the most accurate way.
Also, there are tables to look it up, but that's not the best solution because the real circumference of a wheel is depending on a few factors wich combine differently on each bike.
