Alignment FAQs

Alignment Basics

Why is a wheel alignment so important?

Picture yourself cruising down the most beautiful road in the world. Now imagine driving down that same road with your wheels pointing the wrong way. Not the most beautiful road in the world anymore.

Alignment is a really complex topic covering a variety of terms and a smorgasbord of parts. When your wheels are out of alignment, your tires aren’t pointing in the right direction. This will affect your steering and suspension, but more importantly, it could affect your safety and the durability of your tires and all the parts controlling them.

What does Camber mean?

Camber plays a major role in your cornering and stability. Now, to give you a demonstration, you’re going to want to use your feet to best understand camber. Let’s get started.

Stand up. No, really, stand up. Now, place all your weight on the outside of both feet. This is what is called “positive camber.” Now do the reverse and place all your weight on the inside of your feet. That’s ’negative camber.’ Positive camber is for stability, while negative camber is common in high performance vehicles that require better cornering.

Quick fact: While some positive or negative camber is good, too much of either is bad.

Diagnostic Terms

What is a thrust angle?

Does the tail wag the dog? Thrust, and its respective thrust angle, all relate to the positioning angles for your back tires.

The thrust angle is the degree in which the back tires try to steer the front of the vehicle and is a major factor in your car’s ability to keep you cruising along a straight path. The more the thrust angle is off, the more the rear of the car will steer the front.

To align a vehicle accurately, it is important to understand the positions of all tires.

Whether your vehicle has a completely independent suspension or not doesn’t matter. It is critical to understand how the rear tires are pointed (thrust angle) to accurately adjust the front tires. It’s a complicated process, but we’ll get you pointed in the right direction.

Symptoms & Solutions

How do driving conditions affect my vehicle’s wheel alignment?

Bad roads can be your wheels’ worst enemy. If you drive down poorly maintained roads, drive through pot holes, or even hit a curb, your alignment can be greatly affected.

This can cause even the slightest, tiniest alignment issue, which can accelerate uneven tire wear. Make sure you have your alignment checked every 6,000 miles or so. Your tires and your wallet will thank you later.
