Pair of 27.5" mountain bike tires. Specialized Ground Control 2BLIS 27.5 x 2.1, kevlar bead. Was used with tubes on road, so pretty clean.

A while back I bought an E-bike for commuting. The prior owner changed the original tires out for these 27.5 knobby MTB tires. I have since changed to semi-slicks, and don't have need for the MTB tires (this is our only 27.5 bike). The one that was on the rear has some tread wear, but the other still has good tread. Picture of tread attached.

Located in Russian Hill in SF. $20 for both.
