Response to original post question
Back to Jim's questions in the first post:
I feel the class should responded positively to Hoosier's willingness to do group purchase batch runs again in the future. It is a simple solution with the least amount of impact to all. I'm sure some friendly buying and selling of unused or needed tires will be commonplace between batch runs. I'm confident it would work.
Worst case, another future group purchase batch run will delay the need to make a change allowing the class time to make an informed decision.
