Revenues [Abstract]
Revenues	Note 8 – Revenues Automotive undercar repair, tire replacement sales and tire related services represent the vast majority of our revenues. We also earn revenue from the sale of tire road hazard warranty agreements as well as commissions earned from the delivery of tires on behalf of certain tire vendors. Revenue from automotive undercar repair, tire replacement sales and tire related services is recognized at the time the customers take possession of their vehicle or merchandise. For sales to certain customers that are financed through the offering of credit on account, payment terms are established for customers based on our pre-established credit requirements. Payment terms vary depending on the customer and generally range from 15 to 45 days. Based on the nature of receivables, no significant financing components exist. Sales are recorded net of discounts, sales incentives and rebates, sales taxes and estimated returns and allowances. We estimate the reduction to sales and cost of sales for returns based on current sales levels and our historical return experience. Such amounts are immaterial to our consolidated financial statements.
