The tyre pressure warning light often comes on after new tyre fitting in the UAE primarily because the Tyre Pressure Monitoring System (TPMS) was not reset to recognize the new sensors, or because a sensor was physically damaged during the installation process. A less common but serious reason could be a poor seal on the new tyre/rim assembly, especially problematic given the high summer temperatures and dusty roads here which can exacerbate minor leaks. According to vehicle inspection data from RTA Dubai, tyre-related faults, including TPMS warnings, are among the top five reasons for initial test failure. The MOI UAE's driving safety guidelines consistently emphasize the importance of correct tyre pressure, particularly for highway driving between emirates like on the Dubai-Abu Dhabi highway where sustained high speeds are common. For most modern GCC-spec vehicles like the Toyota Land Cruiser or Nissan Patrol, the reset procedure is specific: you typically need to drive at a steady speed above 25 km/h for about 10-15 minutes on a road like Sheikh Zayed Road after initially checking and adjusting all pressures, including the spare, to the recommended cold pressure level (usually found on the driver's door jamb). If the light remains, a damaged sensor valve stem—often cracked by an impact wrench—is likely, requiring a visit to a specialized tyre shop for a diagnostic scan and potential sensor replacement, which for a 2023 Toyota Hilux might cost around 250-400 AED per sensor.
