Title: I can't stop looking at my Front Tyre
Post by: Tony Mac on January 22, 2015, 12:12:10 AM
Good afternoon all,
My front tyre has worn a flat spot around it, just off centre on the "Off Side"
It appears as if I favour right hand corners, in fact it is so worn it looks like all I do is turn right.
Some people say its the Round a Bouts we have in abundance over here.
I'm wondering if having the rear wheel out of alignment might cause this. although I would think that all it would do is Crab Walk a little.
I might put it on the bench tonight and do some measuring.

Has anyone else had this happen to them.
You guys in the U.S. would have the wear on the "LHS" of your tyre, given that you ride on the wrong side of the road an'all.
Any advise would be greatly appreciated.

Be Good.
Tony Mac.

It's from the camber in the road we get it on the right side and in the states on the left. I find if I run a higher pressure 42psi I can minimise the scalloping some what.


Cheers

Something else to consider is to make sure that both fork legs are clamped in the same position in the triple tree.

Yep  :good: and check and make sure the forks are set so the spring preload is the same...

It may be time for some fresh fork juice...

Another possibility, is that it could be a reflection of riding style and comfort zone. 

Do you find that you are more comfortable in left hand curves as opposed to right hand curves?

Do you find yourself 'riding the front' more (braking or coasting rather than accelerating) through corners in general, especially right hand corners?

If so, then you can mitigate the issue by attempting to get back on the throttle sooner.  In particular try focusing on being at a comfortable entry speed before you 'tip in' to the curve.  That way you can roll on the throttle sooner and let the rear tire take the brunt of traction.

+1 Yeah , what they said.

You may want to get the string out and check alignment of front to rear wheel .  Laser works great as well .

A simple check is to ride a level road and take your hand off the bars briefly to see if the bike rides straight . This may not work with old tires sometimes.

Thanks for your advice Guys.
The tyre pressure was down to about 27 psi  and I found the Right Hand fork leg slightly lower that the left.
Here's what the tyre looks like.

Here's what the tyre really looks like.

Sorry Guys, I guess I needed a few more lessons on posting photos.
I also took the advice of previewing the post this time. Thanks for that.

Tony, the LHS isn't that far behind the RHS. From the photo, I would  think it was normal wear from the camber of the road. There is a point where the difference in wear from one side to the other appears greatest, you may well just be at that stage with you tyre wear.

If that was my tyre, I wouldn't give it a second thought other than I would need a new tyre soon.
