Since purchasing the Tire Pros franchise program from AM-PAC Tire Distributors Inc. five years ago, American Tire Distributors Inc. hasn't focused on growth for growth's sake.

It has focused on "sustained" growth.

There were close to 180 Tire Pros franchise locations on Dec. 31, 2008. At the 2014 Tire Pros Dealer Meeting in Las Vegas, ATD executives placed the up-to-date number at 560 locations (owned by 408 dealers).

"We have not outstripped our resources, our ability to support the growth," said Dan Brown, president of the Tire Pros franchise program. "We have been very congnizant of that."

In 2013, the program added a number of affiliated marketing and social media vendors.

More than 600 dealers and guests are attending the event, which began on Feb. 4 and runs through Feb. 5. Total attendance, including vendors, is 850 people.
