How Do Forward Collision Warning Systems Work?

Forward collision warning systems use radars, lasers, and cameras mounted onto your windshield to detect objects in front of your vehicle. When these sensors notice an obstruction, be it another vehicle, pedestrian, cyclist, or another object, the driver will be alerted visually or audibly. Some vehicles may even alert the driver both ways. No two systems work the same, but the driver will typically receive some form of alert, or combination of alerts, to slow down (unless your vehicle employs automatic emergency braking, in which case it will brake on its own). Check your owner’s manual to determine how your forward-collision warning system will behave. 

Understanding how your ADAS and forward collision warning features work before operating your vehicle is crucial. According to a study by the American Automobile Association (AAA), ADAS features, specifically forward collision warning systems, ‘have the potential to prevent 40% of all vehicle crashes and nearly 30% of traffic deaths when utilized properly.’ But this doesn’t mean you should rely on them wholeheartedly. Even if your vehicle is equipped with a forward-collision warning system, it’s essential to remain alert behind the wheel.

When to Have Forward Collision Warning Systems Repaired

As mentioned above, a forward-collision warning system relies on windshield-mounted cameras, lasers, and sensors for road feedback to operate effectively. If your windshield becomes damaged to the point that you need to install a replacement windshield, you will need to recalibrate your ADAS and forward collision warning systems as well. Failure to do so will result in these safety features working incorrectly, as the readings they receive from the windshield-mounted cameras and sensors may not be accurate. Even the slightest miscalibration of these sensors can affect performance.

This is how many layers of rubber and other materials are in the tire.  

The speed rating of a tire is based on U.S. Government standards for reaching and sustaining a specified speed. Typically, a tire with a higher speed rating results in better handling. Speed ratings apply only to the tire itself, and not to a particular vehicle. Putting a tire rated for a certain speed on a vehicle does not mean that the vehicle can be safely operated at the tire's rated speed.

What makes up a tire; each ply, the sidewall, the tread, and bead.  

This number will tell you how well the tire will disperse heat buildup. 

The measurement, in inches, from rim flange to the other rim flange. 

Tread depth is the distance between the top of the tread rubber to the bottom of the tire's deepest grooves.  In the United States, tread depth is measured in 32nds of an inch.

A tire’s maximum load is the maximum amount of weight the tire is designed to hold. The tire’s load carrying capacity is directly related to the tire’s size and amount of inflation pressure that is actually used. Each load range has a assigned air pressure identified in pounds per square inch (psi) at which the tire's maximum load is rated.

The total width of the tire, including any raised features on the sidewall. 

The load range on a tire helps determine its ability to contain air pressure and its overall strength. Ranges are expressed using a number and the higher the number, the stronger the tire. These measurements are primarily for light trucks and SUV’s.

The maximum width of a wheel that a tire can be put onto. 

A tire's section width (also called "cross section width") is the measurement of the tire's width from its inner sidewall to its outer sidewall (excluding any protective ribs, decorations or raised letters) at the widest point. 

The minimum width of a wheel that a tire can be put onto.  

This is how much weight a tire is rated to hold.

The mileage warranty of a tire indicates the number of miles that a tire is estimated to last. If a tire fails to last for the number of miles indicated by the warranty, the customer will be given credit from the tire manufacturer toward a new tire based on how many miles short of the estimate the tire fell. Some restrictions apply. 

A tire’s maximum inflation pressure (PSI) is the highest "cold" inflation pressure that the tire is designed to contain. When measuring a tire’s max PSI, it is important the tire is "cold," because warmer temperatures can cause the tire pressure to temporarily increase resulting with inaccurate readings. This measurement should only be used when called for on the vehicle’s tire placard or in the vehicle’s owners manual.

Components of the Tire Pressure Monitoring System (TPMS) sensor wears over time.

A TPMS Service Kit is suggested each time a tire/wheel is serviced. If left unchanged, over time, these components of the TPMS may corrode, leak or fail.

Tire/wheel service is defined as when tire is removed from the wheel.

The represents the smallest and widest size wheels that are recommended by the tire manufacturer for the tire to be mounted on.
