Hey all, I just purchased a used
Bike off CL and first thing I noticed is it's really loud. Its not the chain it's apparently just the tires when rolling. Both tires seem to be running pretty true as true As a ten year old bike can be but they are just loud. I have a suspicion the wheel bearings need to be greased. Is this a DIY sort of a job for a noob? Or should I jus take it to the LBS? Or should I just leave it alone, it helps alert peds on the MUP of my prescense lol.

It seems like its both the front
And back wheels if that matters.
