    Tire Mounting Direction?

    I'm in the process of replacing the original tires that came with my Grom with some Michelins I bought.

    These are the arrows shown on the sidewalls on the front and rear tires.




    I've already reinstalled the front wheel with the arrow next to the the word "Front" facing the forward direction of the bike but how should I mount the rear tire which only has the one word, "rear", and corresponding arrow as shown in the pic?

    IIRC the arrow is the direction of travel. (well, direction of rotation.) If your arrow is on the top, it should be facing forwards.

    For tires that can be used on both front and rear, the front is reversed because its used for braking (pushing the bike backwards-ish) rather than pushing the bike forward.

    Why do motorcycle front and rear tires have opposite tread patterns? ? Ramblings of a Singapore Biker Boy

    above posters are correct, arrow dictates the direction of rotation depending on where it is mounted. The reason for the two different arrows on the front is because its designed for both front and rear.

    Motorcycle tires experiences different forces at each end, braking on the front and acceleration on the rear. That's why when you see matching tread tires on a bike it looks like one tire was mounted on the rim in the wrong direction, but it is correctly mounted.

    Thanks for the replies. I wanted to be absolutely sure about how to mount the rear tire before I went ahead because it's bit of a wrestling match to get the buggers on the wheels.

    Yeah for some reason these 12" wheels have been the biggest PITA for me as well.
