Is this tire worn enough to cause a front end vibration?

Recently (like in the past week) my bike has started to vibrate when riding at speed. Seems to be road speed dependent, but overall the bike squirms around and the bars pulsate a bit at higher speeds. Just wondering what your opinions are. Thanks.

Just about down to the wear bars on the sides, by the way...

On edit:

The bike has 4900 miles, with the original tires.

You bet it is bad enough to feel a vibration on the road. That tire is badly feathered. I would call it shot! B'stone 020's were never good on the front end of a KRS/GT.

You have to realize that most tires are as good as they get for the first 2,000mi. then they start to fall off.

I don't see any "feathering" or cupping. Still not worn down to the wear indicators, but the BT020's do have a bad reputation on our bikes. I would change it and see if it solves your problem.

I'm no tire expert, so maybe there isn't any cupping...but looks like it to me, based on the shadows around the sipes. Might be the cause of the vibration, though.

Looks pretty much the first set of tires I had on my 2004 GT. I've found the Conti Road Attacks are pretty good about not cupping as bad. I also found the Road Attacks that are specific for the BMW's are better then the normal Road Attacks. I have about 11,000 miles on the BMW Road Attacks and they have just started to cup to the point I can feel it. I will be replacing them soon.

I recently replaced the Strada on the front when the TWIs were exposed in several spots, and I didn't feel any sort of vibration.

The tire was cupped, also.

Rather than push my luck with worn tires (and they are cupped) for a 700+ mile ride this weekend, I decided to get them replaced.

I really wanted the Conti Road Attacks, but alas the only tires anyone has in stock by Friday are the Metzeler Z6's. Oh well, I guess people are happy with those as well.

I don't mind the tires wearing out at 5k. I just want a tire that grips well and when it wears, wears evenly and keeps its ride and balance. The original fitment BT020's are not the ticket (on this bike or on my '02 KRS).
