Uneven tire wear pattern?

Just noticed on my rear tire that it is wearing more to the left of center than on-center. This woud tend to indicate I'm riding with a slight lean to that side. Anybody got any insight into what I may be doing technique wise to cause this? (and no, I don't ride in counterclock wise circles!) Any possible equipment situations to look at? Thanks.

Are your roads really highly crowned toward the center such that you really are riding mostly on the left side of the tire?

...Road crown is an interesting hypothesis.

I have observed a slight off-center balance point some riders seem to have going down the road. I have had a similar wear condition on my Bianchi tires. Having had this wear condition I've noticed that the bike's balance point makes it hard to track straight with "no-hands".

Perhaps the front fork has a slight twist or the chain stays are not parallel. Sorry I don't have any answers here, just collaborating your observation. I wonder if this wear condition occurs more frequently on steel framed bikes.

All my bikes have had the same wear pattern to some extent, it's caused by road crown. Locally the roads have almost no crown and the wear pattern is almost centered.

check to make sure wheel is aligned in the dropouts also...have you ever crashed the bike? it may indicate a misalinged frame. Also let the air out of the tire and reset the bead on both sides. Hope this helps...ride on VikeAz

Lazygolfer: Hadn't thought about road crown. I'll pay some attention on my next few rides. Don't think it's significant, though.


Bikerjohn: My bike's balance point may be off cause "no-hands riding" is difficult. I was attributing that to my age.....maybe it's the bikes fault!

vikeaz: Alignment in the dropouts seems okay. I have crashed once; laid it down after touching the wheel in front of me. Didn't seem to have any damage other than scratched shifter hoods. LBS looked at it and didn't see any concerns. I'll try letting the air out and reseting beads.

Thanks all.

Its due to road crown. Motorcycles wear their tires the same way.

Looks like a concensus for road crown being the cause. That's good. Much better than bad equipment or riding technique.

Thx for the input.

What exactly happens when you ride no-handed? Is it pulling in a particular direction?

This may be embarassing, but since I started riding last year, my on-bike balance is extremely poor. When I rode in college, many, many years ago, I had no problems riding no-handed. Now, when I attempt to ride with no hands, I'm very tentative.....I don't notice any particular pull, just an overall unsteadiness that makes me nervous, so I seldom remove both hands. I've attributed it to age; I'm now 51. However, I've not noticed any other "balance" issues in my life activities. And general balance/manuverability on the bike hasn't been a problem.
