Firestone Studded Ground Grip Enduro/Jack Pine Tires

 One NOS one used
Firestone Studded Ground Grip

5.25 - 5.50 - 18

I had some questions regarding tires lately. Here are a couple of the Firestone Studded Ground Grip tires. I have seen these on "Jack Pine" and "Sandy Lane" Enduro bikes from the 40's and early 50's. I've had these for decades waiting on the right project. Yeah that's pigeon shit...
Not for sale just informational.


  1. Tire info from Matt: The front is a 4.00x19 grasshopper, and the rear is a 6.00x16 allstate knobby tire. You can buy the same tire but the firestone version from coker they call it a knobby truck tire
