Site Prove, Customer Preferred

I was experiencing repeat bond failures at one of my customers - a large food distribution center. I had tried many different products and found nothing would meet my customer’s work-life expectations. Superior Tire took the time to meet with my customer and identify a solution - the Cushothane® XL™ compound. Since using the Cushothane® XL™, my customer has been extremely happy. They no longer have to spend extra time and money on maintenance and new wheels from premature bond failures. They were so impressed with the work-life that I have now made this the “compound of choice” at other customer locations. With the Cushothane® XL™, I know that my customers are guaranteed to have no bond failures."
