Title: Michelin Pilot Street rotation direction
Post by: Kilted1 on March 25, 2019, 01:09:36 PM
Just put a set of Pilot Street tires on and my kid (who worked in a tire shop till recently) pointed out that the front tire was on backwards.  I told him no, it's on the right way and pointed to the arrows showing the intended direction of rotation which I had triple checked not paying attention to the tread.  He pointed out the tread design which if rotating that way will bring water into the center of the tread rather than away from it.  I have to agree with him on that and the rear is designed the other "right" way. 

So anyone know what's up here?  Did Bridgestone just mold the arrows in backwards?  Is there something at work here I'm not seeing?  Do I reverse the tire or just leave well enough alone?

Has anyone else noticed this about Pilot Streets?  I looked around and didn't see anything here or elsewhere on the topic.

I noticed it on mine but never really questioned it. I'm gonna dig into it a bit after I'm done here at work cuz now you've got me curious....

go by the little arrow on the sidewall.  Front and rear tires typically go on with the tread in opposite directions.

Don't try to figure out how the water goes, it will hurt you brain...the engineers already figured it out for you...go by the little arrows.

LOL!  Thanks for that.  I'll trust that they know more than I do about their area of specialty.

Great article!  I can now tell my teen kid who knows everything that he's wrong.    :flipoff:

Seems to me that one would have to be going faster than I'm ever likely to in the wet to experience hydroplaning.  But it does make sense to think of the tread profile as seen by pavement while cornering and braking.

Thanks for the responses, all!
