2. The Production Date is Located on the Sidewall

Another misconception is that the production date of a tire can be found on the sidewall. While it is true that the sidewall of a tire contains important information, such as the tire size, load index, and speed rating, the production date is not among them. Instead, the production date is usually found on the inner side of the tire, known as the bead area.

• The production date is not on the tire sidewall.
• The bead area of the tire is where the production date is usually located.
• Manufacturers may use different codes or formats to represent the production date.

3. The Production Date is Obvious and Easy to Identify

Some people believe that the production date is clearly marked and easy to identify on a tire. However, this is not always the case. The production date is often represented using a code or format that may not be immediately understandable to consumers. It usually consists of a combination of letters and numbers, and deciphering it requires some knowledge or information from the tire manufacturer.

• The production date may not be easily recognizable to consumers.
• Manufacturers may use different codes for representing the production date.
• Online resources or contact with the manufacturer may be needed to understand the production date code.

4. The Production Date Does Not Affect Tire Performance

One misconception is that the production date of a tire has no impact on its performance. However, the production date can have significant implications for a tire’s performance and safety. Over time, tires can age and degrade, and using tires that have passed their expiration date can increase the risk of tire failure, such as blowouts or tread separations.

• Using tires beyond their expiration date can be dangerous.
• Expired tires may experience reduced traction and handling capabilities.
• Performance and safety of a tire can be compromised as it ages.

5. Production Date is Irrelevant If Tires Are New

Lastly, people often assume that the production date is irrelevant if they are purchasing new tires. However, even if tires are brand new, they can still have been produced months or even years before purchase. This is especially true for less popular tire sizes or specialized tires. Therefore, it is crucial to check the production date even when buying new tires to ensure they are not already close to their expiration date.

• Even new tires can have been manufactured earlier.
• Checking the production date is important regardless of whether the tires are new.
• Older new tires may have shorter remaining lifespan compared to recently manufactured tires.
