Car tire inspection and quality control within the car tire industry starts at the supplier of raw materials. The car tire manufacturer will contact an specialist such as an Intouch Quality Control specialist who will test the raw materials in china before being shipped to the to the tire manufacturer. Samples during the mixing process should also be tested to confirm strength and density of the rubber.

To ensure consistency with the initial samples, tires must also be taken off the assembly line  for destructive testing. The following are some destructive tests performed during the quality control process.

Quality Control Tests for Car Tires:

Below are a few car tire quality control tests that must be performed by a quality control specialists when importing and exporting car tires to China.

• Stopping Distance
• Tire Traction Under Varying Conditions
• Traction in a Straight Line on Snow and Ice Covered Surfaces
• Braking Force
• Skid Resistance
• Tread Footprints
• Tread wear Data Analysis
• Irregular Wear Patterns
• Standard Test Method for Single Wheel Driving
• Wet Traction Braking

Test for Tire Performance Testing on Snow and Ice

The test for tire performance testing on snow and ice are a series of driving maneuvers performed in a vehicle. These techniques are used to characterize the aspects of the car tires performance on snow and ice surfaces .

Test for Measuring the Groove and Void Depth on Car Tires

The groove and void depth affects the tires ability to create traction on wet pavement, snow, slush and dirt. It also affects the ability to resist hydroplaning.

Groove and void depth defines the condition of the wear of a tire and is also used to determine the rate of wear.  Any optical, electronic or mechanical device capable of measuring groove and void depth can be used to perform this test.

 
 Other types of car tire quality control tests performed involves tests such as slicing open a car tire to check for air pockets between the body plies. Another test performed is when a car tire is pressed down using a mechanical device onto pointed metal studs to determine puncture resistance. Sometimes even car tires are rapidly spun and forced onto a steel or metal drum to test the car tire for mileage as well as other performance characteristics.
