They're designed for 1.9 to 2.2 tires, and since they came out c. 1988, they might be the earliest method for using modern tires on a vintage buggy. Unfortunately they're pretty heavy so probably not ideal for racing.
Also does anyone know if they take dye? One pair I got is yellowed, and if peroxide can't get them white I'd like to dye them. Worried the plastic they're made from might warp in boiling water though.
