Understanding MG RX5 Wheel Alignment

Proper wheel alignment is crucial for several reasons:

  • Tire Longevity: Correct alignment ensures even tire wear, extending the life of your tires and saving you money in the long run.
  • Fuel Efficiency: When wheels are properly aligned, there’s less rolling resistance, which can improve fuel economy.
  • Handling and Safety: Proper alignment contributes to better handling, steering response, and overall vehicle stability, enhancing safety on the road.
  • Comfort: Misaligned wheels can cause vibrations and pulling to one side, leading to an uncomfortable driving experience.


Camber is the inward or outward tilt of the wheel when viewed from the front. The MG RX5 has a slightly positive camber (0.23°) for the front wheels and a negative camber (-1°) for the rear wheels. This configuration helps improve cornering performance and stability.

Kingpin Caster

Caster angle affects steering, stability, and cornering. The MG RX5’s caster angle of 4.95° provides a good balance between straight-line stability and ease of steering.

Toe-in Angle

Toe refers to the inward or outward pointing of the wheels when viewed from above. The MG RX5 has a slight toe-in for both front (0.13°) and rear (0.2°) wheels. This helps with straight-line stability and reduces tire wear.

Kingpin Inclination Angle

Also known as steering axis inclination, this angle affects the vehicle’s ability to self-center the steering wheel after turning. The MG RX5’s 12.75° inclination provides good steering feel and return.
