If changing to a larger tire than stock, what does everyone do about the change in accuracy of the speedometer. Guessing most leave it alone and not worry about it? I hate to have things not quite right and when changing to a larger tire, would like my speedometer correct or stay with stock size tires. I don't do the heavy muddin, just trail ridiing so probably don't need larger tires, but sounds like larger tires have a lot deeper tread depth which may ge bood or may be bad for my type of riding.
