Will a motorcycle fender fit over 26x4 fat bike tires?

If you don't already know, motorcycle tire size goes by inner diameter, whereas bicycle tire size goes by outer diameter. For instance, a 16" motorcycle tire will fit a 20" bicycle rim. This may effect your calculations.

That explains why my 21 inch front trail motorcycle tire looks so big. I was amazed at how well a 21 inch tire absorbed all the potholes and washouts. I never really thought about it being different than a bicycle tire, seems stupid once I think about my mistake.
