Posted this on the What did you do to your Tri today thread.
"I finally got the buzz fixed on my Avon Trike Front Tire ... but ... I shudder to tell ya how ...
I actually took it to a buddy who is the Service Manager at a Honda Dealer. They balanced the tire in 30 minutes and did actually have to add weights.
The indy that installed the tire originally, then removed the RideOn, and rebalanced it said that it balanced with no weights. I've been riding some form of bike for 50 years and have never seen that before ... I'm sure it happens, just never seen it.
Anyway, after balancing, I headed to the highway and voila, no buzz."
