What Is Camber On A Car? Positive vs. Negative Camber Effects

What Is Camber On A Car

Have you ever wondered what that weird tire wear pattern is on your vehicle’s tires? Or maybe you’ve noticed your car pulling to the left or right and can’t figure out why. Chances are, these issues are caused by something called camber angle – but what exactly is camber and how does it impact your car’s handling and performance?

In short, camber is the inward or outward tilt of your wheels from true vertical. Camber angle affects tire wear, grip, steering response, and high-speed stability.

This comprehensive guide digs into everything you need to know about positive and negative camber so you can understand how it impacts your vehicle. We’ll cover:

  • Defining camber angle and how it works
  • The differences between positive and negative camber
  • How camber impacts tire wear, traction, handling, and more
  • Recommended camber settings and alignment
  • Frequently asked questions about camber

So whether you’re just looking to brush up on suspension basics or fix an alignment issue on your vehicle, read on to get the full scoop on camber.

What Exactly Is Camber Angle?

Camber angle refers to the inward or outward tilt of your wheels from true vertical when viewing the vehicle head-on. This is different from caster angle, which is the forward or backward tilt of the steering axis.

Camber is a key element of wheel alignment that directly impacts how your tires contact the road. The camber setting is adjustable on most vehicles within a certain range.

Here’s a quick breakdown of how it works:

  • Positive camber means the wheel is tilted outward at the top. The tire has less tread contact with the road.
  • Negative camber means the wheel is tilted inward at the top. The tire has more tread contact on the road.
  • Zero camber means the wheel and tire are perfectly vertical.

The camber angle is measured in degrees from the vertical axis, with negative angles for inward tilt and positive angles for outward tilt. Most passenger vehicles have a slight negative camber setting from the factory for optimal handling.

But what effects does adjusting the camber angle have on tire wear, traction, steering response, and performance? Keep reading to find out.

Understanding Positive Camber Effects

Setting positive camber means tilting the tops of the wheels outward from vertical. Here are the main effects of positive camber:

  • Reduces tire wear – With less tread contact on the road, there is less scrubbing action during cornering to wear down the tires.
  • Improves high-speed stability – The outward tilt causes a trailing wheel effect for better directional stability at higher speeds.
  • Provides a smoother ride – Positive camber allows the tire to absorb shocks more easily than a vertical or negative setting.

The main tradeoff is that positive camber reduces overall grip and traction since less tire tread is in contact with the road. For this reason, most passenger cars come from the factory with a very slight negative camber setting.

Some vehicles that benefit from added positive camber include lifted trucks, vehicles with stiff lowered suspensions, and race cars driving mostly in straight lines at high speeds like drag racing.

Exploring the Effects of Negative Camber

In contrast to positive camber, negative camber tilts the tops of the wheels inward, increasing tread contact with the road surface. Here are the notable effects of negative camber:

  • Increases grip and traction – The greater tread contact allows more grip when cornering, accelerating, and braking.
  • Enhances steering response – The tire flexes less with more tread on the pavement, allowing quicker turn-in.
  • Lowers rolling resistance – Less tire flex decreases drag for better rolling efficiency and fuel economy.
  • Causes more inner tire wear – With greater pressure on the inside edge, inner tire wear increases, especially on front-wheel drive cars.
  • Harsher ride – Less shock absorption with the tire pressed flat to the road leads to a rougher ride over bumps.

The extra traction advantage is why most cars come with a slight negative camber setting from the factory. But too much negative camber can accelerate inner tire wear.

How Much Camber is Ideal?

So what are the ideal camber angle settings? It depends on your vehicle, tires, driving style, and needs. But here are some general guidelines:

  • Passenger cars – Range from -1 to -2 degrees camber up front, and -1 to -1.5 degrees in the rear.
  • Sports cars – May have up to -3 degrees of negative camber in front for sharper handling.
  • Pickups and SUVs – Require between 0 to -1 degrees of camber to prevent uneven tire wear when loaded.
  • Lowered cars – Often need increased negative camber in front (-2 to -3 degrees) to keep tires flat on the road.

These are just starting points – your specific alignment will depend on the vehicle manufacturer’s specifications. A professional alignment check is recommended any time you lower a vehicle or notice uneven tire wear that could be alignment-related.

There are also camber adjustment kits available that allow lowering the top of the strut to add more negative camber on lowered cars. This helps restore proper geometry and prevent inner tire wear issues.

How Does Camber Angle Affect Tire Wear?

The camber setting directly impacts how your tires wear over time. Here’s an overview of how positive and negative camber can affect tire tread wear:

  • Negative camber – Accelerates inner edge wear, especially on front tires. Can lead to “camber wear” with more tread depth on outer edges.
  • Positive camber – Causes more wear on outer tread edges. Makes tires “feather” and wear unevenly across the tread.
  • Excessive camber – Too much camber in either direction results in uneven tread depth and poor handling.

Besides camber, other alignment settings like toe can also cause tire wear. Your first step in preventing uneven tire wear is to get a professional 4-wheel alignment.

From there, you may need camber adjustment kits or an adjustable lower control arm to dial in proper camber if you lower your vehicle. This helps eliminate inner edge wear issues.

Frequently Asked Questions about Camber

Is negative camber bad for your car?

Negative camber is not inherently bad – in fact, it’s necessary in proper alignment settings to increase grip and traction. The key is not having too much negative camber, which accelerates inner tire wear. Around -2 degrees up front is optimal for most vehicles. Excessive negative camber beyond -3 degrees causes uneven tire wear and poor handling.

Does positive camber affect handling and steering?

Yes, positive camber reduces overall grip and traction since less tire tread contacts the road. This makes for vague or slower steering response. A little positive camber on the rear helps stability at speed but too much up front degrades turn-in and handling precision through corners.

Can too much camber damage tires?

Absolutely. Excessive camber, either positive or negative, can rapidly wear down tires. Severe cases destroy tires in just a few thousand miles. Too much camber also makes the vehicle handle poorly and wander on the highway. Damaged tires need replacement and proper alignment adjustment.

How often should camber angle be checked?

Camber should be checked anytime you install lowered or raised suspension components, or start noticing uneven tire wear patterns. For regular maintenance, have alignment checked at least once a year or every 10,000-15,000 miles to ensure proper camber and prevent tire damage.

Let’s Recap – What We Learned About Camber

Camber may sound complicated at first, but it’s a vital wheel alignment setting that directly impacts tire wear, grip, handling, and steering. Here are the key takeaways:

  • Camber is the inward or outward tilt from vertical when viewed head-on
  • Negative camber increases grip, while positive camber enhances stability
  • Most cars need a slight negative camber setting for optimal handling
  • Too much camber in either direction accelerates tire wear
  • Lowered vehicles often need more negative camber to avoid inner tire wear
  • Have alignment with camber checked yearly to prevent uneven tire wear

Understanding the effects of positive vs negative camber gives you insight into proper alignment settings. With this knowledge, you can dial in ideal camber for enhanced performance, handling, and effective tire wear.

Your wheels and tires connect you to the road – be sure to give them the proper camber angle advantage!


Camber might seem complicated when you first start tinkering with suspension tuning. But mastering proper camber settings is crucial for balancing tire wear, grip, handling, and high-speed stability.
