1. Torque requirements vary by vehicle make and model, and these specific values can usually be found in the vehicle's owner's manual.
2. The torque required for tire bolts on family cars is generally in the range of about 100-120 Nm. When tightening tire bolts, a specific tightening sequence should be followed, that is, tightening them diagonally and in three stages, which ensures that the bolts are evenly stressed, making the tire installation more stable.

The size of the car tire titanium hub bolt?
Don't worry, let us reveal the secrets for you. Usually, the sizes of tire bolts for cars we see are mainly 19mm and 21mm, which are adapted to the special needs of different car brands. Take Toyota cars as an example, they prefer 21mm bolts, while Honda chooses 19mm specifications. Volkswagen models prefer 17mm bolts. In the Mercedes-Benz brand, small cars use 17mm bolts, while large cars use 19mm; the same is true for BMW, small cars use 17mm, and large cars use 19mm.
However, tire screws are not uniform, their diameters usually range from 14mm to 20mm, and the pitch varies from 1mm to 2mm. These screws use fine-pitch triangular thread design to ensure the stability of the connection. The choice of specific model often depends on the model of the car and the configuration of the tire. Some models may use 17mm, 19mm, 21mm or 22mm bolts, and the design of 5 or 4 fixing screws is also quite common.
In domestic mini cars, 14mm bolts are common, while German cars such as Mercedes-Benz, BMW, and Audi usually choose 17mm bolts. There are many models of domestic sedans and SUVs, so there are both 17mm and 19mm bolts. Japanese Toyota sedans tend to use 21mm bolts, while off-road models prefer 22mm bolts. In general, although the world of tire bolt sizes may seem complicated, as long as you know your vehicle, you can easily find the right size.
