What’s a Tire Safety Report?
A clean vehicle and a safer vehicle - Thanks to exciting new technology provided by Tire Discounters, customers of The Carriage House Car Wash in Kings Mill are getting both. As you go through the wash bay, our safety equipment measures your tread depth. Then an easy-to-read report is created for you. You can access your report by texting the word SAFETY to 67032 and providing your license plate number. The results are available within one business day after you go through the car wash.
Please note - The equipment may not read your license plate correctly if you have any of the following:
- License plate cover
- A new license plate or changed license plates
- A dealer license plate
- You drive an emergency vehicle
Here’s a sample...
How to Read the Report – Tread Depth
Tire tread depth is the measurement between the top of the tire and the tire’s deepest grooves. This section measures your tread depth in four places of each tire. Measuring the tread on your tire is important because it can show any issues you may have with your tires and your vehicle.

A new tire should show the same tread depth across all four measurements on the tire. Tread depth is measured in 32nds of an inch. If a tread depth says 8, that means you have 8/32 of an inch tread depth.
Each tire’s beginning tread depth will be different. A new passenger tire will be in the range of 7-10/32, while a larger truck tire may be in the range of 10-14/32. A tire’s tread will wear as the vehicle is driven. In most US states, tires are legally worn out when tread depth reaches 2/32. Many tire manufacturers recommend tire replacement when the tread is worn down to 3/32.
How does tread depth impact me?
Tire tread depth is important because a tire’s grooves squeeze out water, debris and snow so tread can contact the road. Tires can hit the road and keep the vehicle running smoothly. As tires wear, tread depth decreases compromising the tire’s ability to make solid contact with the road. As tread depth decreases, the vehicle’s wet weather stopping distance increases.
How to Read the Report – Wet Weather Stopping Distance
Remember when you were studying for the driver’s license test, and it asked you how many car lengths you should keep in between you and the next car? That’s kind of what wet stopping distance is. The Wet Stopping Distance measurement on the report says how many feet it will take your vehicle to come to a complete stop at 60 mph.
When calculating the minimum stopping distance, the following assumptions are being made:
-
Initial velocity of 60 mph
-
Driver & vehicle reaction time is instantaneous
-
Max braking force is being applied on all 4 wheels
-
No incline or decline on road
-
Straight line stop
-
No wheel lock-ups or hydroplaning
-
Tire to road coefficient of friction is constant
If any of these measurements are red, you should get your alignment checked by a Tire Discounters ASE certified technician. Ignoring these signs can make your alignment problems more expensive to address down the road, can reduce the life of your tires, or cause driver assist systems to malfunction.
