What causes the Mercedes GLC260 to display abnormal tire pressure?
1 Answers
The reasons why the Mercedes GLC displays insufficient tire pressure are: air leakage from the tire or valve stem, which needs timely repair; wheel rim deformation leading to reduced tire sealing performance; long-term overloading of the vehicle causing uneven tire stress; thermal expansion and contraction resulting in insufficient tire pressure. The standard tire pressure is 2.4-2.5 bar; reinforced tire pressure is 2.8-2.9 bar; the maximum pressure should not exceed 3.5 bar. If no visible damage is found, you can directly inflate the tire to the normal pressure and reset the tire pressure system. If a puncture is found during inspection, drive to a tire shop promptly for repair, then reinflate the tire. If the tire pressure warning reappears some time after inflation without any punctures, it may be due to air leakage caused by wheel rim deformation. It is recommended to check and replace the wheel rim.
