What is a Camber Angle?

Jeremy Laukkonen

Camber angle is a measurement used in the wheel alignment of automobiles. It refers to the angle of a tire in relationship to the vertical axis of the tire when viewed from the front or back of the vehicle. If the bottom of the tire is farther away from the vehicle than the top, it can be said to have negative camber. If the top of the tire is farther away from the vehicle than the bottom, it can be said to have positive camber. A wheel that is perfectly vertical would have zero camber.

Tractors will sometimes have a positive camber angle to make them easier to turn.

The camber angle directly affects the way a vehicle handles and is taken into consideration when a suspension system is designed. An incorrect camber angle can result in a variety of undesirable consequences, such as improper tread wear or poor handling. Camber angle is only one of the many variables that affect the way any particular vehicle handles.

A tire with zero camber, or a tire that is perfectly vertical when viewed straight on, can impart advantages for a vehicle on straight-line acceleration. This is because a tire with zero camber will have the most contact with the ground when moving straight ahead. A negative camber angle will give similar advantages when turning. This is why vehicle makers will usually be strike a balance between the two, depending on the intended use of the vehicle.

Camber is a measurement that will usually be taken when checking the alignment of a vehicle, though not all vehicles allow for adjustment to be made. Cars with McPherson strut suspensions typically have a fixed camber, though some allow an adjustment to be made where the struts bolt to the knuckles or hubs. Vehicles with a double wishbone type suspension allow for adjustment in many more applications. Adjustment may be required if the vehicle suspension is raised or lowered, parts are replaced, or the vehicle is in an accident.

Though negative camber can be instrumental in the handling of many vehicles, positive camber does see use in many non-automotive applications. Slow-moving off-road vehicles such as tractors will often have a positive camber angle to lessen the effort of turning. Positive camber is also sometimes used in the "taildragger" type landing gear of planes designed to take off and land on rough, unimproved surfaces. Positive camber might be undesirable, or even dangerous, in automotive applications, but it can have a desirable effect in the right applications.

@NathanG - Yeah, I know what you mean. It does seem to make sense to have negative camber for those racing cars. Although I would argue that what it provides in performance it gives up in safety.

I think those tires that are angled that way have less traction because not all the tire tread is on the ground at all times. At the same time, I can see how if they had zero camber they wouldn’t be able to spin at all, and would probably flip at every corner. It’s a delicate balancing act.


Wheel camber is probably not something that the average consumer should be too concerned about – but it is useful to know if you are racing car fan like me.

From this article, it would appear that some of the “souped up” racing cars you see on the track have negative camber angles. The tires are tilted inward so to speak, in an almost exaggerated manner, to give the car better performance on the track and of course, enable it to turn quickly around corners.

I don’t know what it does for the wear on the tire tread, but in my opinion these things don’t matter, because there is always the pit stop right around the corner where they can get new tires in jiffy.

The rest of us have to drive our cars for the long haul, so the positive stability of zero camber tires is the only way to go from what I can see.
