Tire rotation direction question

it doesn't really matter now because the tire is worn out, but after looking at the way the siping runs on this tire it looks like it was installed backwards. Can anyone verify?

 

Can't tell by the pic, but to know for sure, check the sidewall and look for the rotation arrow.

 

Yes what Ootv said

 

Duh.

it was on correctly. I always thought siping was supposed to run from center to outer edge as the tire rotates. This one (Michelen Pilot Power) doesn't.

 

A couple moto tire brands are like that. Seems to be hit or miss with what the manufacturer wants to do. Conti's are the same as your I believe.

 

I had someone tell me that my PR2 tire was on backwards but I pointed out to him the directional arrow on the sidewall was correct. I heard someone elsewhere say that Michelin did this to enhance the braking ability on wet surfaces. Can't say if it does or not as I don't really ride in wet weather that often, nor do I have any way to compare how it works in the opposite direction. Sounds plausible though.

 

I have Pilot Road 3 on my bike. Front tires are out-to-in while the rear is in-to-out. (They are installed correctly).

 

I did a tire course while in my late teens, job bouncing. The reason your tires siping on a front tire (directional tires only) goes backwards is because as you ride forward through water it travels ahead of the tire in a wave. This hollow point can be filled with the water under your tire. The water comes in behind the tire to fill the void left by the tire.

That was the explanation on that course. I know its not the total truth and was dumbed down a lot. There was also explanations on how siping helps create grip etc. I took that course 13yrs ago and havent done a thing with it since.....

Anyone whom can add/ correct please do.
