Wish I could tell you what brand they are but they are not clearly marked with a brand. The rear tire has medium size writing that reads Tractor Grip and 20X2.125 and small printing that says Made in USA as well as tire pressure. Similar to old Schwinn, but are not Schwinn. The tires are a matched set and I can tell you they are old, I got them a while back from a guy who had a bunch of old bike parts. They are in surprisingly good preserved condition, and ride really nice.
