my Toyota Corolla E210 (2019-2024) has uneven tire wear, what causes this?

Solution

1. Preparation

• Gather necessary tools and parts.
• Ensure the vehicle is parked on a level surface and the parking brake is engaged.

2. Adjust Tire Pressure

• Use a tire pressure gauge to check the pressure of each tire.
• Inflate or deflate tires to the manufacturer's recommended PSI, which can be found on the driver’s side door jamb.

3. Perform Wheel Alignment

• Lift the vehicle using a hydraulic jack and secure with jack stands.
• Remove the front wheels using a socket set.
• Connect the alignment machine to the vehicle’s wheel hubs.
• Adjust the camber, caster, and toe settings according to the manufacturer's specifications.
• Reinstall front wheels and torque to manufacturer specifications.

4. Inspect and Replace Suspension Components (if necessary)

• Visually inspect struts, shocks, and bushings for signs of wear.
• If any component shows damage, remove the affected parts:
  • For struts, remove the bolts securing the strut assembly and replace with new components.
  • For bushings, press out the old bushings using a bushing tool and install new ones.
• Reassemble suspension components and ensure all bolts are torqued to specifications.

5. Tire Rotation

• Rotate the tires according to the recommended schedule (typically every 5,000-7,500 miles).
• Move front tires to the rear and rear tires to the front, crossing them to ensure even wear.
