I have a Back trails 4 function computer for my mongoose MB and am having problems finding a calibration code for my tire size(26x2.30).
Can any one help?

Does not list your tire size, but will get you very close. Also shows how to calibrate manually using roll out.

By coincidence I had a Cateye manual open in another window. They don't list 26x2.30 but the do have 26x2.35 as having a 2083mm tire circumference.
