What are the terms for a wheel alignment?

There are several ways that alignment (sometimes called ‘tracking’) is measured and corrected. These calculations are known as the caster, camber, toe and thrust: Caster: compares the steering axis to the vertical axis, when the car is viewed from the side.

What are the 3 alignment adjustments?

There are three main wheel alignment angles, which determine how each wheel is positioned relative to the car, the ground and each other. These are camber, caster and toe. Camber and Toe angles refer directly to the wheel, while Caster on the other hand is a measurement of the suspension geometry.

What are the three terms dealing with vehicle alignment that can affect tire wear?

Alignment has three main parameters: Camber, Caster and Toe-in. Camber is the tilt of the tire from top to bottom. If the tire tilts in at the top (towards the vehicle), it has “negative” camber. If it tilts out at the top (away from the vehicle), it has “positive” camber.

What is a 4 tire alignment?

A 4-wheel alignment refers to adjusting all four wheels, which is typically required on all-wheel-drive models, with independent suspensions. This may include a front toe and caster adjustment, just like the front end alignment, while the rear wheels receive a toe and camber adjustment.

What are 3 different types of abnormal tire wear?

Tire Tread Wear

Center Wear. If one or more of your tires are worn down the center — but not on the sides — the culprit is most likely an overinflated tire.
Side Wear.
Cupping Wear.
Feathering.
Flat Spot Wear.
One Side Wear.

What is castor adjustment?

Caster, which is also referred to as caster angle, is the top to bottom angle of the steering axis and suspension components as they meet the wheel. Caster is an alignment adjustment that occurs on the turning wheels only, i.e., the front wheels of a vehicle.

Do I need an alignment after replacing tires?

We recommend an alignment after the installation of new tires. This helps you get the most life from your new tires. Wheel alignment checks are always advised after a significant impact or uneven tire wear is detected. Also, get a check annually, or twice yearly if you typically travel on rough roads.

Do I need a 2 or 4 wheel alignment?

Typically, if your vehicle is an all-wheel-drive model comprising independent suspensions, it will need a 4-wheel alignment. Service consists of a caster and front toe adjustment. For the rear wheels, they’ll receive a camber and toe adjustment.

Do I need all 4 wheels aligned?

Yes, the majority of vehicles today (cars, small SUVs, and vans) require a four-wheel alignment. But even in the case of two-wheel alignments, your technician can check the rear tires for damage that may compromise your car’s handling. If all four tires can be aligned, they should be.

How do I know if I need a 2 wheel or 4 wheel alignment?

A 2-wheel is also known as a front-end alignment. As suggested in its name, the technician performs alignment on only the front wheels. This may include a camber, toe, and caster adjustment. Your car will typically require a 4-wheel alignment if it’s an all-wheel-drive model with independent suspensions.

What causes cupping?

Suspension components like shock absorbers, struts, bushings and others wear out with miles travelled. The result can be a tire that is no longer able to roll smoothly down the road; instead, it bounces slightly. This bouncing creates uneven points of pressure on tires, leading to tire cupping.

What is Wheeltoe?

Toe is a measurement that determines how much the front and/or rear wheels are turned in or out from a straight-ahead position. The amount of toe, whether it’s toe-in or toe-out, is expressed as the difference between the track widths as they are measured at the leading and trailing edges of the tires.

How often should you get a tire alignment?

As a general rule you should follow your owners manual recommendations, but a general rule of thumb is to have your tires and wheel alignment checked every 10,000 miles. If you drive on roads that are riddled with potholes and uneven pavement, you should get it checked more frequently (5,000 – 7,500 miles).

Should I get alignment before new tires?

No it is not required, if your old tires show signs of misalignment, inside or outside wearing faster it is highly recommended to maximize the life of your new tires. It in my book is a good time to have the alignment at least checked.

What does tire alignment mean?

Tire alignment, also known as wheel alignment, can help your tires perform properly and help them last longer. It can also improve handling and keep your vehicle from pulling in one direction or vibrating strangely on the road.

Is alignment required when getting new tires?

Yes, you can get an alignment before buying new tires. It doesn’t matter whether you get your alignment before or after having your new tires put on. Most experts agree that the only effect worn tires have on your alignment is a change to the vehicle’s ride height which, given today’s steering and suspension design, should be negligible.
