Expensive parts such as alloy wheels are often purchased second-hand. When choosing used discs, you should pay attention not only to design and shape, but also to quality. In addition, when purchasing these parts, it is important to take into account their parameters so that they fit your car.
Necessary
used alloy wheels, wheel balancing machine
Instructions
Step 1
Measure the rim diameter and rim width of the discs used. Pick up identical ones. Bore diameter - the size of the circumference of the annular part of the rim of the disc on which the tire rests. Width determines the size of the profile of the tire fitted to the alloy wheel. The deviation of the value of this value from the landing width is allowed only by one inch.
Step 2
Determine the overhang of the part. This is the distance from the disc plane adjacent to the hub to the plane mentally drawn through the center of the rim landing width. It is measured in mm. The classic outreach for a passenger car is 30-40 mm. Its value can fluctuate around 10 mm. A significant deviation from the nominal value will cause the tires to cling to the suspensions and wheel arches.
Step 3
The diameter of the circle of the centers of the mounting holes of the rim should match that of your car. If there is a significant deviation in the value, the fastening bolts will be skewed.
Step 4
The value of the diameter of the center hole of the cast disc must correspond to the value of the protrusion on the hub, which performs the centering function. A slight deviation is allowed only upwards. Centering rings are used if available. Check if the discs you are purchasing have any. They must be included.
Step 5
Examine the discs carefully for snoring. This is the name of the small annular projections on the surface of the parts. They are necessary in order to better fix the tubeless tire. The temples keep it tight.
Step 6
Check the geometry of the disks. To do this, you need a balancing machine. Not every tire changer has it. Call several stations in advance to check availability. As a result of a check on the machine, it will be found out how much the geometry of the disks is violated and whether it can be corrected. Try to find out at the station how much the repair will cost and where it is best to do it (if it turns out that such work is not done in this place).
