Hi all - I changed both tires on my bike a couple of weeks ago and over a week ago I started feeling a grinding from the front tire when I bike. I never felt this with the old tires, so I think it's weird that it should start when I changed the tires. I'm assuming this is a hub issue and getting it overhauled? (no, the brake pads are clear of the rim) Any input is appreciated. How much does this usually run? Thanks.
