Solution

1. Tire Pressure Adjustment

Sub-steps:
1. Use a tire pressure gauge to measure the pressure of each tire.
2. Inflate or deflate tires to match the manufacturer's recommended specifications (located on the driver’s side door jamb).
Tools Required: Tire pressure gauge, air compressor.
Safety Warnings: Ensure the vehicle is on a flat surface when measuring tire pressure.

2. Tire Rotation

Sub-steps:
1. Lift the vehicle using a jack and secure it with jack stands.
2. Remove each tire and rotate them according to the recommended rotation pattern for your vehicle (typically front to back and side to side).
3. Reattach each tire and ensure lug nuts are torqued to specifications (typically around 100 Nm).
Tools Required: Jack, jack stands, lug wrench, torque wrench.

3. Wheel Alignment

Sub-steps:
1. Take the vehicle to a professional alignment shop.
2. Have the technician perform a four-wheel alignment to adjust camber, caster, and toe settings to factory specifications.
Tools Required: Professional wheel alignment machine.

4. Suspension Inspection and Repair

Sub-steps:
1. Inspect struts, shocks, and bushings for wear.
2. Replace any worn or damaged components as needed.
3. Recheck alignment after suspension repairs.
Tools Required: Socket set, pry bar, torque wrench.
Safety Warnings: Always wear gloves and safety glasses when working with suspension components.

5. Tire Replacement (if necessary)

Sub-steps:
1. If tread wear is excessive, replace tires with new ones that meet OEM specifications.
2. Ensure new tires are balanced properly.
Tools Required: Tire mounting machine, tire balancer.
