Two Alternatives – Both Baaaad.

What do you have for a spare under the truck? I would run the 3 liberators and the spare. Or as suggested, put the bad liberator on the back. Carry some weight in the bed and it will help with the shimmy. An out-of-round tire is not necessarily an unsafe tire, unless you can visibly see defects. I've also heard of people doing a 1 tire fire burnout to wear the tread round. But inflate it to the max pressure before doing it.

 

just run the toyo's. may seem sucky to run a winter tire, but look at it this way, run the good toyo's and not worry the whole time if something will happen OR run the liberators and wonder if something is going to happen. either way, you will have to buy a new set of tires eventually.
