Tyre alignment is a term that refers to the position of each tire and/or wheel relative to your car and all your other tires. When properly aligned, your tires point in precisely the same direction, moving your vehicle over the road as smoothly and efficiently as possible.
Wheel alignment is an affordable service that can easily make you save money. Indeed, your new tyre investment can be wasted by a bad tyre alignment. Wheel alignment is part of your car maintenance and must be checked regularly in order to avoid risks on the road. Read how to identify a bad wheel alignment and why checking and maintaining the alignment of your tyres is key for your security and your budget!
What is vehicle wheel alignment?
The purpose of a tire alignment is to adjust the angles of your tyres so they are both perpendicular to the road and parallel to each other. At TYRE & AUTO we use sensitive computerized tyre alignment equipment to measure all adjustable and non-adjustable alignment angles. (Non-adjustable angles that are off require repair or replacement of the suspension component.)
The four most common adjustable angles are:
This term refers to the direction that your tyres tilt toward or away from one another when viewed from the top. Tyres that "toe-in" point toward one another. Tyres that "toe-out" point away from each other. When it comes to stopping premature tire wear, toe is the angle we’re most concerned with.
This term refers to the direction that your tyres tilt toward or away from one another when viewed from the front. Tyres that tilt in toward the vehicle have "negative camber." Wheels that tilt away from the vehicle have "positive camber."
This term refers to the angle of the steering axis in relation to an imaginary vertical line that runs through the center of the tyre when viewed from the side. "Positive caster" is the term used when the vertical line is tilted toward the rear. If it's tilted forward, we call it "negative caster." The proper caster angle stabilizes your car and allows for better steering.
This term refers to the relationship of all four tyres to each other, as well as their relationship to an imaginary center line that runs from bumper to bumper. The term "thrust line" refers to the direction in which the rear tires are pointed. Thrust angle is correctable on cars with adjustable rear suspensions. If your vehicle has a non-adjustable suspension, thrust angle is compensated for by aligning the front tires to the rear tyres.
