What would cause cupping on a brand new front tire?
I got the S21 tires about a month ago and just noticed what looks like an odd wear pattern. I'll have to get some chalk and raise the front tire to tell for sure, but it looks like cupping right off the center on the throttle side.
I'm still checking this out, but I'm wondering what would cause this so I can start looking for the problem.
I'm thinking head/wheel bearing, alignment to the rear tire, alignment withing the forks, etc...
I know with car tires you can tell things like toe in/out, camber, etc... by looking at the tires, but I don't know how to do this with a motorcycle tire.
I think if I raise the front and spin the tire, I should be able to tell if there's any cupping and maybe get some pics of it.
