When talking about tires, they are measured in 32nds of an inch. A wear bar is as 2/32" tread depth (no longer a usable tire). If you have 1/4" of tread then you have 8/32" of tread on the tires (which is excellent wear for 50K). I would have someone look at them and properly measure them with a tread depth gauge. This is done by measuring the center, inside and outside of tread. Some other situations most people do not notice are dryrotting, runflat conditions (which looks like an indented ring worn out of the sidewall), and also cupping. All these should be considered when replacing tires.
