Our Vision

GM Defensive is a defense industry contractor, trusted by worldwide armored forces. It produces solutions for the land armies of various states and organizations or companies with military vehicles to manage their military tires more effectively.

Our Mission

GM aims to provide the best solutions with the best product quality to the armies of many different countries or to defense contractors with armored vehicles. Currently, GM’s most important project is the run-flat tire changing machine. GM’s goal is to introduce the run-flat tire changing machine to the whole world, to transport it and to enable it to be used. One of these solutions is the run-flat changer machines for military and armoured vehicles. Run-Flat Tire Machine has 3 types that provide different usage areas and convenience in line with the needs and demands of the buyer. The standard workshop model(GMR-023) comes into operation and does not change location if certain workshop and electrical conditions are met. Container model(GMH-098) is a run-flat tire changer machine that can be operated inside a 20 ft container. Since it is a container, it can be transported and better adapts to harsh working conditions. Another Run-Flat Machine model is with the trailer one(GMT-099). This model has wheels that can move and can be attached to the back of trucks. GMT-099 is preferred according to the distance, displacement and mobility preference of the armored vehicles from the workshop. The trailer model also carries a run-flat tire changing machine in a 20 ft container. Our containers have international transit certificates.
