Maggie Front tire

Why would you turn the tire to change the direction of rotation of a rear tire when using it on the front? I would think a unidirectional tire is designed to roll in one direction only.

I believe I have read before the reason is on Unidirectional tires you reverse them on the opposite wheel because Rear wheels main stress is acceleration and the front tires main stress is braking.
All of the acceleration comes from the back wheel and 70% of braking comes from the front wheel. This puts the most force on the tire in the direction it was intended to take the most stress.

Thanks for clearing up the mystery for me, Hootmon! I learned something useful today from that!

YEP HOOTMON is correct, atleast as the Avon rep explained things to me when I was looking into running a Avon rear for the front of the Project 96 Magna.

After he said all that he quietly told me that he didnt see any issues running it for a front..

I too did research through Avon when I bought the AM 26 for my magna front.  It was marked as a rear tire at the time but now the same tire is marked as Unidirectional.  The Avon reps told me the only difference the unidirectional had would be the absence of the arrow.  I haven't put a lot of miles on mine yet so I can't attest to the wear but I am impressed with the handling of the Avon tires.  I have had an AM 42 on the rear for over a year now.
