Looking at the front of the bike, tread is worn more on the left side than the right. What causes this ? Tires have a little over 8100m on them. The back needs replaced too, but is worn right down the middle

 

My guess is you are more aggressive on your right turns than left???

 

Alignment?

 

I would think something is wrong with your bike. However I had a tire wear like that on the front of my pickup recently. there was nothing wrong with the alignment. It was an expensive tire to boot. So maybe it is just a problem with the tire itself.

First bike Ive had in a long time so I don’t drive overly aggressive in turns. I do open it up a little on highways but not twistys...yet. I just ordered a set from revzilla but I’d like to figure out why the front did that before I have the new tires mounted. Thanks for the replies
