Zhuzhou Jinxin Tire studs is a hot-selling product, but do you know how to install it ?  
 

Firstly, Measure the depth of the hole to be studded with a tire tread depth gauge. If the measurement is 10, then the proper size carbide tire stud is the 11-12mm. If the measurement is 12, then the proper size is the 13-14mm, etc. 
  

Then Align the tip of the stud gun with the hole. Press the stud gun assembly firmly downward inserting gun tip into hole.  
  

Finally, Depress the stud gun trigger while maintaining downward pressure, release the trigger and relieve the downward pressure.
