Brothers Darrin and Tracy Karst began in the automotive industry working for their Dad Alvin growing up. With a love of the industry they began to branch out into tires. Moving to the current location in 1994 they began as a Tire Craft until 2008 when the parent company went bankrupt. Being an associate store they were able to carry on business as usual and were soon flying under the Integra Tire corporate banner. Serving southern Saskatchewan, they have grown the business from "just" a tire shop to being able to provide a full line of both heavy duty and automotive mechanics. They have top of the line equipment to serve their customers to the best of their ability. The staff has grown from the original to at current 19 employees. Darrin, Tracy and staff look forward to serving you in any way they can!

Kyle can be found in his Dad’s (Tracy) shadow on any given day. When not in school, he loves to visit with customers, as well as staff. He and his Dad like to work on personal vehicles together on weekends, as well as on the side-by-side. Kyle enjoys spending time helping Uncle Darrin work on his car when he is able to ( sometimes "help" doesn't always make the job easier!). As well he loves spending time with his older cousins. He often needs to be reminded that he is much younger than them! Kyle is always willing to lend a hand if needed or even an ear if the phone needs to be answered. We’re sure as soon as he is old enough he will find himself on the payroll!
