Can low tread on the front tire cause severe vibrations on the handlebars? Lately on decel, usually in 4th gear around 40-50 mphs, my handlebars have been shaking pretty rapidly. What would cause something like this??

 

Worn tread can definitely cause some strange occurances.&nbsp\\;

 

How are your steering head bearings? I adjusted mine and got rid of most of the shaking.

 

Low tire presssure can cause it too.

 

I've been getting this also.
I&nbsp\\;sometimes shake my hands out when decelerating and just noticed the bars were shaking... grabbed back on quickly!
I checked the air and it was around 35...what is a good pressure to run?
I've got 7300 miles on my bike, hate to think it needs a new tire.
