INCREASE SERVICE SALES FOR THE PRICE OF A QUARTER
Most customers know that their tire tread depth should be at least to the top of Washington's head on the US quarter. So give your service advisors a roll of quarters. When the customer pulls their car into the service lane, require your advisor to walk around the vehicle and measure every tire. Check the inside and outside wear.
If the tires are wearing evenly and of a good tread depth, give the customer the quarter along with a business card.
If the tires are not wearing evenly, a rotation is needed. Maybe even an alignment is needed. All this while the customer sees the quarter test.
If the tread depth is below the top of Washington's head, here is your opportunity to sell a set of tires and time to exam the brakes. This is also a good time to educate your customers on the necessity of good tread depth.
Your customer will appreciate the attention. They have seen this common test even if they do not understand the meaning. You educate your customer in the products available, there is no reason for them to go to a tire store or anywhere else.
All of this for the price of a quarter.
