Lot of 6-395/85/20 VF0018 Hutchinson Run Flat Inserts
I periodically get to Bismarck and Dickinson.
They are made to go inside military truck tires to keep going if get a flat tire.
Another possible use would be for power lifting etc as their about 115-125lbs a piece cant remember which one but heavy. I have 6 of them. If dont want all of them can split up.
They are brand new from place in Pennsylvania; all were in box and first place I took them to took one out when tried and threw the box away. I do have them stored in garage and the one out of box is in garage too.
