Front tire bumps

I have a 2011 Electra Glide Classic. I run a street glide front wheel with Pirelli night dragon tire with roughly 10,000 miles on it. The tread is above 60%, but I have noticed bumps on the tire. What is this from and how concerned should I be?

Do you mean cupping? If you run your hand down the tread of the tire is the surface uneven?

Can be caused by improper tire pressure, or a defective tire. It will cause increased vibration and poor handling.

Had the same issue with a factory installed dunlop on my 09 FLHTC. Both front bearings were bad and the previous owner had 26 psi of air in the tire. Replaced the bearings and tire.
