This is nothing more than capitalism at work. Hoosier, like all other companies, are not in business to make tires. They are in business to make money. They do it by making tires. They find the top price that people will pay, and charge that. That maximizes profit. It happens every day, with every product. It always has and always will.
Yes the price seems high to me, but I thought gas was too expensive when it went to a dollar a gallon back in the day.
