As a responsible vehicle owner, it is imperative to prioritize every aspect of your vehicle’s maintenance, including the condition of your tyres. The manufacturing date of a tyre plays a crucial role in determining its quality and longevity. Over time, tyres naturally age, which can have a significant impact on their performance, grip, and overall safety. Therefore, having a solid understanding of how to check the manufacturing date of Yokohama tyres becomes vital in making well-informed decisions when it comes to purchasing or maintaining them.

Understanding Tyre Manufacturing Date

The manufacturing date of a tyre refers to the specific date when it was produced. This date is typically encoded within the DOT (Department of Transportation) code, which is a standardized marking mandated by law in numerous countries. You can find the DOT code conveniently located on the sidewall of the tyre, usually comprising a combination of numbers and letters.

Importance of Checking Tyre Manufacturing Date

Checking the manufacturing date of Yokohama tyres holds immense significance for several reasons:

  1. Safety: Tyres progressively deteriorate over time, especially when exposed to harsh weather conditions or improper storage. Utilizing old or expired tyres compromises your safety on the road, as their grip, handling, and braking capabilities may be significantly diminished.
  2. Performance: Newer tyres are meticulously designed to provide optimal performance, encompassing enhanced fuel efficiency, superior traction, and a more comfortable ride. By checking the manufacturing date, you can ensure that you invest in tyres that meet the latest industry standards, offering the finest performance for your vehicle.
  3. Warranty Coverage: Tyre manufacturers often offer warranty coverage based on the manufacturing date. Being aware of the date helps you determine if your tyres are still within the warranty period, thus enabling you to take advantage of potential free repairs or replacements.

Longevity and Maximizing Performance: One of the key advantages of purchasing tyres with a recent manufacturing date is the opportunity to maximize their lifespan and enjoy reliable performance for an extended period. By selecting tyres that are newly manufactured, you can ensure that they are in prime condition and capable of delivering the performance you expect.

How to Check Yokohama Tyre Manufacturing Date?

To determine the manufacturing date of Yokohama tyres, follow these simple steps:

Locate the DOT Code: Begin by locating the sidewall of the tyre. On the sidewall, you will find a series of characters engraved. Look for the DOT code, which is typically positioned near the rim of the tyre.

Decoding the DOT Code: The DOT code consists of a sequence of numbers and letters. The last four digits of the code specifically indicate the manufacturing date. For instance, if the last four digits are “3519,” it signifies that the tyre was manufactured during the 35th week of the year 2019.

Identifying the Manufacturing Date: The manufacturing date is primarily represented by the first two digits of the four-digit code. These initial two digits correspond to the week, while the remaining two digits signify the year. For example, if the last four digits are “3519,” it means that the tyre was manufactured in the 35th week of 2019.

Factors Affecting Tyre Longevity

While the manufacturing date provides valuable insights into a tyre’s age, it is important to consider other factors that can influence its longevity. Factors such as proper maintenance, road conditions, driving habits, and climate all play a role in how well a tyre performs over time. Regularly inspecting and maintaining your tyres, including checking tyre pressure, rotating them periodically, inspecting for signs of damage or wear, and aligning the wheels correctly, can help extend their lifespan and optimize overall vehicle safety.

The Dangers of Using Expired Tyres

Using expired or old tyres poses significant risks to both your safety and the performance of your vehicle. Over time, the rubber compound in tyres undergoes deterioration, resulting in reduced grip on the road surface. This diminished traction can lead to longer braking distances and an increased likelihood of accidents. Additionally, old tyres are more susceptible to sidewall cracking and blowouts, which can be extremely hazardous, especially when driving at high speeds. It is crucial to prioritize safety by avoiding the use of expired or severely worn tyres.

Regular Tyre Maintenance

To ensure optimal performance and safety, it is essential to adhere to regular tyre maintenance practices. This includes checking tyre pressure regularly, rotating tyres at recommended intervals, inspecting for any signs of damage or wear, and ensuring proper wheel alignment. By implementing these maintenance routines, you can maximize the lifespan of your tyres and enhance overall vehicle safety.

Extended Storage of Tyres

If you have spare or unused tyres that require extended storage, it is vital to store them correctly to maintain their quality. Ideally, tyres should be stored in a cool, dry place away from direct sunlight and sources of heat. They should be kept upright or suspended to prevent deformation and damage. Additionally, covering the tyres can provide protection against dust, debris, and potential ozone damage, ensuring they remain in optimal condition until needed.


DOT regulations

Tire Identification Numbers (TINs) must start with the letters DOT, followed by eight to thirteen characters, per DOT regulations. The DOT records typically list the week and year a tyre was made, its size and type code, and the manufacturing location’s code. Date codes must also be shown on the exterior walls of vehicles as mandate by the DOT.

DOT code

The FDAPLJO4518 DOT identification number is presente. The tire’s origin is indicate by the first two letters (FD). The following two characters, AP, represent a size code. The next three characters, LJO, represent the tire’s type code, while the number 4518 represents the DOT manufacture date. This FD designation is for the Yokohama Factory in Japan, as confirmed by the DOT. Tires with the AP size and the production code 4518 were manufacture during the 45th week of 2018.

Highway tires

DOT-approve highway tyres are expecte to perform well in the laboratory tests specified by Federal Motor Vehicle Safety Standard (FMVSS) No. 139 for radial tyres on light vehicles. In this case, “motor vehicle” means any vehicle with a GVWR of 10,000 pounds or fewer that was produce after 1975, excluding motorcycles and low-speed vehicles. Tire marking, tread wear indicator, dimensions, tubeless tyre bead unseating resistance, tyre strength (plunger), tyre durability, low-inflation performance, and high-speed performance are all tested in accordance with FMVSS 139. To be sold, a DOT tyre must first demonstrate compliance with all DOT regulations.


In conclusion, checking the manufacturing date of Yokohama tyres is of utmost importance for ensuring safety, performance, and an enjoyable driving experience. By understanding how to decode the DOT code and identify the manufacturing date, you can make informed decisions when purchasing new tyres.
