I have 4 used KO2 BFGs that were on my Jeep for about 45k miles. they're rated at 50k, and these have about 5/32nds left. no plugs or patches, one tire has a small amount of outside wear from the torque twist with my Jeep.

they're good for spares or to get you by through winter. asking $200 OBO.

I also have 1 brand new 35 KO that has never touched the ground. asking $100 OBO.
