What is the torque for wheel bolts?
2 Answers
Automotive wheel bolt torque standards vary depending on the vehicle model, and the specific value should be referenced from the manual. Generally, for household passenger vehicles, the torque ranges between 90-110N. Below are precautions for tightening car wheel bolts: 1. Tightening sequence: Car wheel bolts should be tightened according to their torque specifications. There is a specific sequence for tightening the bolts, which should be done diagonally in three stages to ensure even force distribution and secure installation. 2. Effects of over-tightening or under-tightening: Over-tightening the wheel bolts can damage them and make future removal difficult. Under-tightened bolts may cause abnormal noises or steering wheel vibrations while driving. In severe cases, it can lead to wheel wobbling and vehicle deviation.
After running a car repair shop for so many years, I can't stress enough how crucial wheel bolt torque is. There's a significant difference between vehicles—Japanese compact cars usually require 90 to 110 Nm, while German cars typically need around 120 Nm. My torque wrench hangs on the wall, and every tire change follows a cross pattern in two stages: first tightening to 80% torque, then driving a short distance before applying full torque. I dread shops that recklessly use impact wrenches—over-torqued bolts stretch and deform, making them nearly impossible to remove next time. Keep an eye on inexperienced tire shop workers; some EVs like Teslas demand higher precision (140 Nm), as incorrect torque can crack the wheel hub.
