Why Do Rear Car Tires Need Alignment?
Your rear car tires need alignment to ensure proper handling, tire wear, and overall safety. Alignment refers to the adjustment of the angles of the tires so they are set to specifications for your vehicle. Misalignment can lead to uneven tire wear, poor traction, and compromised stability while driving.
The National Highway Traffic Safety Administration (NHTSA) defines wheel alignment as the adjustment of the vehicle’s suspension system to ensure that the tires are perpendicular to the road and parallel to each other. Proper alignment helps maintain optimal performance and longevity of tires.
Several factors can cause misalignment of rear tires. These include hitting potholes or curbs, driving on rough roads, or general wear and tear over time. When your car’s alignment is off, it can lead to the rear tires being tilted inward or outward. This misalignment affects how tires make contact with the road, resulting in uneven wear patterns.
Technical terms related to alignment include camber, toe, and caster. Camber is the angle of the tire when viewed from the front; toe refers to the angle when viewed from above, and caster is the angle of the steering axis when viewed from the side. These angles must be within specific ranges to ensure the tires work effectively and safely.
The mechanism behind tire alignment involves the suspension system, which connects the tires to the vehicle’s body. When this system is out of adjustment, it alters how weight is distributed across the tires. This can lead to rapid wear and insufficient grip during acceleration and braking.
Specific conditions that lead to alignment issues include frequent driving on uneven surfaces, carrying heavy loads, and poor driving habits such as abrupt turns or hard braking. For instance, if a vehicle frequently hits deep potholes, the impact can knock the alignment out of specification, resulting in premature tire wear and potentially jeopardizing safety during drives.
