⚠️ Safety Warnings

Important safety information - read before proceeding

•Ensure the vehicle is securely lifted and supported before working underneath it.
•Wear appropriate safety gear such as gloves and safety glasses during repairs.

Symptoms

•Noticeable bald spots or excessive wear on one or more tires
•Vibration or noise while driving
•Vehicle pulling to one side while driving
•Decreased traction in wet or slippery conditions
•Increased tire pressure loss over time

Diagnostic Steps

1
Visual Inspection of Tires**: Examine all tires for uneven wear patterns, such as cupping, scalloping, or bald spots.
2
Check Tire Pressure**: Use a tire pressure gauge to verify that all tires are inflated to the manufacturer's recommended pressure.
3
Inspect Wheel Alignment**: Use an alignment tool or take the vehicle to a shop to check if the wheel alignment is within specifications.
4
Inspect Suspension Components**: Visually check for worn or damaged suspension parts like bushings, control arms, and struts.
5
Review Tire Rotation History**: Check if the tires have been rotated according to the manufacturer's recommended schedule.
6
Examine Steering and Suspension Systems**: Look for play in the steering rack or loose components that could cause dynamic changes in tire contact.

Solution
