"NEW OLD STOCK" (front and back tire)
One tire is a 20"x2.125 - read it could be for a Schwinn Gripper 60s and 70s Stingray Black Bicycle Cheater Slick.
The other tire is 20x1.75 -Also read that it could be for a Mustang Schwinn.
They were from the John Deere shop in Moline, IL back in 1970's
WOULD APPRECIATE ANY INFO ON THESE TIRES.
05/2/19 - I just read that a Goodyear Grasshopper Tire 20x2.125 Yellow Black Strip Schwinn Stingray Silk sold for $149.99. I am not sure if this is the same as the tire I have.
Comes from a pet and smoke free environment.
I live in SE Naperville.
