What should not be bent, damaged, or rusted through and should be evenly centered, with the dual wheels and tires evenly separated?
- A.
Spacers
- B.
Lug Nuts
- C.
Rims
- D.
All of the above
Correct Answer
A. SpacersExplanation
Spacers should not be bent, damaged, or rusted through and should be evenly centered, with the dual wheels and tires evenly separated. This is because spacers are used to create space between the wheel and the hub, allowing for a wider track width or clearance for larger brakes. If the spacers are bent, damaged, or rusted through, they may not provide the necessary support and stability, which can lead to uneven tire wear, handling issues, and potential safety hazards. Therefore, it is important to ensure that spacers are in good condition and properly installed.Rate this question:
