The cause of a huge number of accidents and road traffic accidents is the untimely replacement of worn-out tires by motorists. Therefore, if you become the owner of a car, you must clearly adhere to the rule: if the rubber is “bald”, it must be replaced with a new one. But here's how to determine if the tires need replacing or not? There are several reliable ways to determine the wear and tear of your car's tires.
It is necessary
- - tire tread gauge,
- - ruler,
- - vernier caliper.
Instructions
Step 1
The easiest way is to measure tire wear with a tire tread gauge. This low-cost and easy-to-use gauge can be purchased from almost any auto parts store or service center where your vehicle is serviced. To determine the amount of rubber wear, turn on the gauge and place it in the tread groove. Then look at the numbers that will be displayed on the screen. If you have winter tires, then the device should show at least 4 millimeters of residual rubber thickness, if summer tires - at least two millimeters. If the tread gauge readings are less, the tires must be replaced
Step 2
Tire wear can also be determined manually using a caliper and ruler.
It is necessary to measure the tread height with vernier calipers. To do this, place the caliper needle in the groove and measure the distance from the bottom of the groove to its top edge. Then pull out the caliper and use a ruler to calculate how much this distance will be in millimeters. The criteria for assessing wear are the same as when measured with a tread gauge: four and two millimeters, respectively.
Step 3
On some tire models, such as Michelin and Nokian tires, numbers are printed on the inside of the tread, which gradually wear off to indicate the degree of tire wear. The number 8 stands for eight millimeters of residual thickness, 6 for six millimeters, and so on. Based on these numbers, you can also not miss the moment when the tires need to be replaced.
