Southern Tire Mart keeps customers moving through service, innovation and people-first values
Southern Tire Mart was founded by Ernest Duff in 1973 and is now owned by brothers Thomas and James Duff, who have grown the business to more than 200 locations across the United States,” begins Tom Fanning, Executive Manager of Operations. “Additionally, through our joint venture with Pilot Travel Centers, Southern Tire Mart at Pilot, we operate a further 150 locations, giving us a network of around 350 sites nationwide.
“In 2025, the company generated more than $3.5 billion in sales, making us the largest commercial tire dealer in North America. We also operate 18 retread plants and produced more than 2.4 million Bandag retreads last year. That scale enables us to serve as a transportation solutions provider rather than simply a tire supplier,” he elaborates.
While Southern Tire Mart’s DNA is rooted in the commercial vehicle sector, its capabilities extend across virtually every tire application, from passenger vehicles and light trucks to industrial, off-road and mining equipment. The company supports everyone from major fleet operators to individual motorists, providing tires, retreading, mechanical services and inspections through a comprehensive nationwide network.
“Our 24/7, 365-day service model is particularly valuable for professional drivers operating under strict hours-of-service regulations,” Tom adds. “With limited time available for refueling, maintenance and essential vehicle upkeep, we aim to be a true one-stop-shop, helping customers maximize uptime while ensuring they still have the time needed to rest and keep their businesses moving.”
The company’s growth strategy is guided by customer demand and a commitment to delivering value through operational efficiency, strategic partnerships and rapid service response.
“Our expansion is really driven by customer needs,” he elaborates. “We focus on growing organically in markets where we can best support our customers, ensuring we have the right network density across the United States. The goal is to be within a few hours of the major interstate corridors so that we can respond quickly whenever and wherever our customers need us.
“That customer-first mindset is reflected in our founder’s philosophy of making money with our customers, not off our customers. While profitability is essential to continue investing in the business, our priority is creating value for customers. We do that by aligning ourselves with the right supplier partners and offering products across every value tier, from premium brands to more cost-conscious options, so customers can choose the solution that best fits their operation.”
Southern Tire Mart also leverages its scale and operational expertise to eliminate waste from processes and pass those efficiencies on to customers. For fleet operators in particular, downtime is one of the biggest costs they face, so the company’s focus is on maximizing uptime through fast, high-quality service and repairs.
“Whether it’s an emergency roadside event or scheduled maintenance in one of our locations, we aim to get customers back on the road as quickly and safely as possible,” he continues. “Time is money in the transportation industry, and our job is to minimize delays, improve reliability and help our customers operate more efficiently.”
Alongside commitment to customers, sustainability is also embedded in Southern Tire Mart’s operating model, with tire retreading and responsible end-of-life management playing a central role in reducing waste and maximizing asset value for customers.
“Retreading delivers benefits from both a cost perspective and a sustainability perspective,” Tom explains. “The last thing we want is an end-of-life tire ending up in landfill when there is still value left in that asset. That’s why we have invested in 18 retread facilities across the United States and developed significant expertise in extending tire life.
“When a tire reaches the end of its original tread life, we’re often able to restore the casing and return it to service, delivering performance that is close to a new tire. In many cases, that process can be repeated through multiple life cycles. Last year alone, we produced more than 2.4 million retreads, representing millions of tires that were kept in service rather than entering the waste stream.
“Eventually, every tire reaches the point where it can no longer be retreaded, whether because of damage, casing fatigue or fleet specifications. At that stage, our focus shifts to ensuring it is disposed of in the most responsible way possible. We explore a range of alternative uses, including tire-derived fuel and other recycling applications, while continuing to invest in new opportunities for material recovery.
“One area we’re actively evaluating is the development of facilities capable of processing end-of-life tires into different grades of rubber that can be repurposed into products such as flooring, mats and other commercial applications,” he elaborates. “We already work with partners to transform recycled tire material into products used throughout our own operations. For example, the branded rubber mats found in Southern Tire Mart locations are produced using material recovered from tires that have been diverted from disposal and given a second life.”
Indeed, retreading and recycling not only help reduce waste, but also conserve raw materials, lower energy consumption and reduce emissions. It’s about extracting the maximum value from every tire while minimizing environmental impact wherever possible.
Likewise, Southern Tire Mart continues to invest in its network and infrastructure, with a focus on increasing efficiency, enhancing product quality and delivering an improved customer experience across its growing footprint.
“We’re constantly looking for opportunities to improve efficiency throughout the business,” Tom adds. “A major area of focus is our retread network, where we’re investing in upgrades and expansions designed to increase capacity, improve operational performance and further enhance product quality. We’re also preparing to build a new retread facility in Florida, which will expand our manufacturing footprint and strengthen our ability to support customers in that region.
“Beyond our production facilities, we’re continually investing in our locations to improve the overall customer experience. That includes modernizing showrooms, refreshing service centers and ensuring our facilities reflect the level of service our customers expect from us.
“What’s particularly exciting is that, despite our size, we continue to operate with an entrepreneurial mindset. Today, we have more than 6000 employees and a service fleet of over 3200 vehicles supporting customers across the country. As we’ve grown, we’ve remained focused on investing in the people, facilities and capabilities that allow us to deliver consistent service while maintaining the culture that has driven our success from the beginning.”
Despite its size and national reach, Southern Tire Mart has retained the culture and agility of a family-owned business, setting it apart from many of its competitors.
“The most interesting thing about Southern Tire Mart is that, despite employing thousands of people across the country, it’s probably the flattest organization I’ve ever worked for,” Tom enthuses. “The owners remain deeply involved in the business and are incredibly accessible. Anyone in the organization can reach out to them directly, and that creates a very down-to-earth culture with strong morale and a real sense of connection throughout the company.
“Southern Tire Mart is part of a much larger portfolio of businesses owned by the Duff brothers, but it’s unique in that it doesn’t have a traditional president or CEO structure. The owners remain closely engaged in day-to-day operations, supported by a lean leadership team and empowered local management. That structure allows us to move quickly, make decisions efficiently and remain highly responsive to both customers and employees.
“Many companies significantly smaller than ours have multiple layers of management between the leadership team and the people serving customers every day. We take a different approach. We believe in giving people ownership, responsibility and the authority to make decisions,” he shares. “That eliminates unnecessary bureaucracy and enables us to react faster while maintaining a strong entrepreneurial spirit across the organization.
“We’re not a company that spends a lot of time promoting ourselves. Our focus has always been on serving customers, selling tires and doing the job well. We’re quiet operators by nature, but we deliver customer service on a very large scale.
“That same philosophy extends to the communities where we operate. While our locations are actively involved in local initiatives across the country, the Duff family has also made significant contributions to education, particularly in Mississippi, where the company was founded and remains headquartered today. Even as the business has grown into a national organization, the headquarters remains in Columbia, Mississippi, the brothers’ hometown, reflecting their commitment to the community that helped shape the company.”
At the local level, teams are deeply engaged in the communities they serve, whether that’s sponsoring youth sports teams, participating in local events or supporting charitable initiatives. “The tire business,” Tom continues, “is ultimately a people business built on relationships, and we’ve always tried to stay true to our roots. No matter how large we’ve become, we’ve never forgotten that our success comes from our people, our customers and the communities that support us.”
While Southern Tire Mart continues to pursue growth opportunities across North America, its long-term success is rooted less in financial targets and more in commitment to its people and customers.
“Of course we want to grow,” Tom says, “and we’re always looking for opportunities to expand into new markets so we can better support our customers, but the philosophy of the business has always been very simple: if you take care of your people, take care of your customers and do the right thing, good things will happen.”
A big part of that philosophy is investing in people; providing leadership development programs, personal development opportunities and extensive technical training to help employees build successful careers. “Our technicians,” Tom elaborates, “receive industry-recognized training to ensure they can perform their jobs safely, efficiently and to the highest standards, while dedicated safety teams work across the business to reinforce best practices and provide the tools employees need to work confidently and safely.
“The work we do can be physically demanding, and in some environments, it can be challenging, so our responsibility is to make sure every employee has the training, support and resources they need to return home safely to their families each day.
“At the end of the day, people grow businesses. Strategies, budgets and plans are important, but they’re only effective when you have the right people behind them. Our role is to create an environment where employees have the tools they need to succeed, because when our people succeed, our customers succeed as well.
“That’s ultimately what defines Southern Tire Mart,” Tom concludes. “We’re much more than a truck tire company. Through our retail, commercial and fleet operations, we support customers across a wide range of vehicle segments and industries. Whatever the application, our approach remains the same: focus on serving the customer, doing the right thing and creating value through long-term relationships. If you do that consistently, everything else tends to take care of itself.”
