A NOS Kenda brand 20 x 2.125 Comp III tread skinwall skin wall BMX tire. This is an original 1980's made tire. I believe the side wall is a skinwall, it looks too textured to be a gumwall side tire. The rubber is still soft, and I believe this would be fine for mounting and riding. Or use it on a carpet queen. Perfect for a mint original bike or for your best restoration. Please email me with any questions.
