cupping tire

Pooker... (orginal poster) Did not state what tires he is using. I had cupping on Avon, now have 10,000 miles on Metzler ME880 (front) NO cupping.
I think Avons have been known to be "soft" compound. I've had good luck with Metzler.

Bridgestone, Dunlop and Pirelli,..............They are all crap!
The Pirelli is a bit better.
Thats all I've tried.

This forum and other forums I belong to... the common theme seems to be "air pressure".
I'm seeing more and more posts about radial MC tires.
P.S>....they are all crap! I run Darkside car tire on my Valkyrie, so I guess that eliminates 50% of the problem. haha

hello to all, i'm new to the message board, but i have a thought on this. cupping on tires can be caused the same way it does on a car or truck, the shocks job is to keep the tire on the road surface, when shocks are worn out, the tires "bounce"on the road and you will see a cupping pattern develope, on a bike this is done through the front forks, fork oil breaks down like all other oil, manual says to change it every 2 years, depending on the age and mileage of the bike it is something to think about, this oil doesn't get changed enough,we tend to forget about it becuase its not as easy as changing the engine oil, just a thought, thanks

Probably the only reason anyone buys Avons. Someone once compared Avons to gummy bears.

11000 miles on my E3 Bias Rear Tire. Still going strong and no apparent cupping.
