I had Avon Cobra on the front and it wobbled like crazy. I could not get close to 100 MPH it wobbled so bad. Also if I lift my hands off the bars it would wobble. Took the tire off and went back to the tire changer to rebalance the tire. We both stood there as the computer balancer did it's thing... showed balanced!
Took the tire off and installed a Metz. Wobble was gone as I went over and beyond 100 MPH with no trouble at all. Wobble was gone at lower speeds as well.
The tire changer guy told me that he has seen a lot of problems with Avons. Customers just was not happy with them and switch them out like I did.
I have had the above conversation more than 3 times on R3owners... lol.
Might as well save it so I can just copy and paste it the next time a person talks about how crappy Avons are.
Of course you will have the very few that state "Oh I've never had any trouble with Avon Cobras". Well they are the lucky few and their time may come if they continue usage.
I believe ever once in awhile the manufacture gets the belts or whatever it is inside the tire aligned correctly so there is no wobble. However why would I buy Avon... install it... run it... and then have to throw it away. $$$$$$$$$$$$
So it's like playing Russian roulette .... you might be lucky.... and then again you might not.
