Everyone knows the “ABC Quick Check” – Air (tread or sidewall damage), brakes (pads and cables adjusted), Cranks (loose?)/Chain (lubed?)/Cassette (worn?), and QUICK Releases (both wheels and brakes). The ABC Quick Check can come in many variations, but the preceding is pretty much it.

In two places, the tread was worn through and cracked with the tire casing fabric showing through. YIKES!
