Solution

1. Tire Inspection and Replacement

Sub-steps:
1. Measure the tread depth using a tread depth gauge; replace tires if tread is below 3/32 of an inch.
2. Inspect for uneven wear patterns; if present, consider tire rotation or replacement.
3. Check for sidewall damage or punctures; replace damaged tires.

2. Tire Pressure Adjustment

Sub-steps:
1. Use a tire pressure gauge to measure the current tire pressure on all tires.
2. Inflate tires to the manufacturer's recommended PSI (found in the owner’s manual or on the driver’s door jamb).
3. Recheck tire pressure after driving a short distance to ensure stability.

3. Traction Control System Evaluation

Sub-steps:
1. Connect an OBD-II scanner to the vehicle’s diagnostic port.
2. Retrieve any error codes related to the traction control system.
3. Address any faults by repairing or replacing the faulty components (e.g., wheel speed sensors).

4. Suspension and Weight Distribution Check

Sub-steps:
1. Visually inspect suspension components for signs of wear or damage (e.g., shocks, struts).
2. Ensure that the vehicle is not overloaded; check the load limits specified by the manufacturer.
3. If necessary, adjust the suspension settings or replace worn components to improve weight distribution.
