DOBBS is your headquarters for Tire Pressure Monitoring Systems (TPMS) maintenance. Our trained tire techs have the skills and knowledge to ensure your TPMS helps keep you safe.    A TPMS system alerts the driver when tire pressure is low. The system may be indirect (part of anti-lock brake system), or direct. A direct system provides separate sensors/transmitters for each tire. SPECIAL CARE MUST BE TAKEN WHEN SERVICING ANY TIRE AND WHEEL ASSEMBLY WITH DIRECT TPMS EQUIPMENT.
