Knowing the manufacturing date of your tires is crucial for your safety and vehicle performance. Worn or old tires can impair braking performance and increase the risk of blowouts. In this article, you will learn everything you need to know about identifying the manufacturing date of tires. We will explain the DOT number, provide practical tips for identification, and explain why this knowledge is so important.
Similar to checking used winter tires on rims, regular tire inspection is also very important.
What Does the Tire Manufacturing Date Mean?
The manufacturing date indicates when the tire was produced. It is not an expiration date, but it provides information about the age of the tire. Older tires, even if unused, can lose quality due to environmental influences such as UV radiation and temperature fluctuations. The rubber compound hardens, leading to reduced grip and an increased risk of cracks. The manufacturing date is therefore an important factor in assessing the condition of a tire.
The DOT Number: Key to the Manufacturing Date
The DOT (Department of Transportation) number is a code embossed on the tire sidewall. It contains information about the manufacturer, tire size, and manufacturing date. For tires manufactured before the year 2000, the DOT number consists of three characters followed by one or two characters indicating the production week and year. For tires manufactured from the year 2000 onwards, the DOT number consists of four digits. The first two digits indicate the production week, and the last two indicate the production year. For example, “2218” means that the tire was manufactured in the 22nd week of the year 2018.

Why is the Manufacturing Date Important?
“The manufacturing date is an important indicator of the safety and performance of a tire,” says Dr. Hans Müller, tire expert and author of the book “The Tire Bible.” “Even if a tire still has tread, it can lose grip and stability due to aging processes.” Knowing the manufacturing date allows you to make informed decisions about the purchase and use of tires.

Practical Tips for Identifying the Manufacturing Date
Locate the DOT number on the tire sidewall. It is usually embossed in an oval field. Pay attention to the last four digits. Decipher the production week and year using the explanation above. If in doubt, consult a tire specialist.

Tire Age and Safety: A Connection
The aging of a tire affects its performance and safety. As a tire ages, the rubber compound becomes harder and more brittle. This can lead to reduced grip, increased braking distance, and a higher risk of blowouts. Therefore, it is important to know the manufacturing date of your tires and check them regularly.
