Change the air pressure and see if the noise changes too.

If it does, then it's prolly just tire wear.

OK, check my air pressure. DON'T BEAT ME UP! there was only 12psi in the front tire. YIKES! :dunno: I'm sure I checked them recently. Going to have to keep an eye on them. Checked it over, no nails, tacks. Somehow it all leaked out.

I just found the pressure down to 12 on one of mine, from sitting all winter. It looked fine, it felt hard, but it was way down.
