I've got Avon Cobras on my bike. They were recomended by the people I bought my rims from (Coastal Moto).
At 9,000 miles the rear tire had just started to touch the wear bars. I'm sure they would have been good for another 2,000 miles. But I like to keep tread on my tires.
Mine seem great no wobble at high or low speed. I am on my 2nd set right now.
