Mismatching tire and wheel component is dangerous A mismatched tire and wheel assembly may explode and can result in serious injury or death This warning applies to any combination of mismatched components and wheel combinations Never assemble a tire and wheel unless you have positively identified and correctly matched the parts ZIPPER RUPTURES A fatigue related damage with or without a rupture occurs in the sidewall flex area of steel radial light and medium truck tires when it is subjected to excessive flexing or heat This zipper rupture is a spontaneous burst of compressed gas and the resulting rupture can range in length anywhere from 12 inches to 3 feet circumferentially around the tire This is caused by the damage and weakening of the radial steel cables as a result of run flat underinflation or overload Eventually the pressure becomes too great for the weakened cables to hold and the area ruptures with tremendous force The RMA Rubber Manufacturers Association states that permanent tire damage due to underinflation and or overloading cannot always be detected Any tire known or suspected of having been run at 80 or less of normal operating inflation pressure and or overloaded could possibly have permanent structural damage steel cord fatigue The RMA has issued a revised Tire Industry Service Bulletin for procedures to address zipper ruptures in certain commercial vehicle tires The purpose of the bulletin is to
