9 months ago I bought a Cruiser bike for riding around my neighborhood, and over that time the tread has worn out completely to the point you can see the cream surface that the interior of the tire has.
My question is, is this normal? For me, this seems very fast for a tire to wear out. In the past I've had mountain bikes and their tires lasted for years and still had plenty of tread.
So is this problem due to a cheap tire, or something else?
