Can someone explain to me what it is!! I cant seem to figure it out. Thanks

 

I have had tires that cause a pull in one direction or the other. I can't say I understand all the reasons, but some of it is due to the belts not being quite right.
Swapping sides may make the pull in the other direction or even it out.

 

Okay just wondering i think im going to try to swap my tires and see if that helps!
