.General Knowledge On Car Tyres.


Vehicle tires have a 4-year validity period from their Date of Manufacture (DOM). Thereafter, the tire expires and may burst whilst in use. How to find out whether your tire has expired? Check for a stamp like this: (*2603*) There is an asterisk at the beginning and at the end of this serial number. The first two numbers 2 6 will tell which week of the year has it been manufactured. 

NB: One year has 52 weeks. The last two numbers represent the year of make. Therefore, *2603* shows that the said tire is manufactured in the 26th week of the year 2003. *2699* this shows that the tire is made in the 26th week of 1999. 

 Check all your tires for safety purposes. Do not use expired tires. They are likely to burst (especially when running in hot weather) because the rubber component may have hardened and cracked.


Studies of tire safety show that maintaining proper tire pressure, observing tire and vehicle load limits,and inspecting tires for cuts, slashes, and other irregularities are the most important things you can do to avoid tire failure, such as tread separation or blowout and flat tires. These actions, along with other care and maintenance activities, can also: 
- Improve vehicle handling
- Help protect you and others from avoidable breakdowns and accidents
- Improve fuel economy
- Increase the life of your tires.

What Information’s you must know about your Car Tires
  • Temperature resistance
  • Traction
  • Tread ware
  • Max. load capacity / tire
  • Speed symbol
  • Manufacturing Date
Where You Can Find These Information

Temperature Resistance
These letters indicates a tire's resistance to heat. From highest to lowest, a tire's resistance to heat is graded as "A", "B", or "C"
Tread ware Number 

This number indicates the tire's wear rate. The higher the tread wear number is, the longer it should take for the tread to wear down. For example, a tire graded 400 should last twice as long as a tire graded 200.
This letter indicates a tire's ability to stop on wet pavement. A higher graded tire should allow you to stop your car on wet roads in a shorter distance than a tire with a lower grade. Traction is graded from highest to lowest as "AA","A", "B", and "C".

 Max. Load Capacity & tire Speed Symbol

Number indicates the max. load that can be carried by the tire. Symbol indicates the max. Speed at which a tire is designed to be driven for extended periods of time.

 Manufacturing Date 

Steps For Maintaining Proper Tire Condition
Just look won't do it

Check your tire pressure monthly

Rotate tires every 5,000 miles (8,000 km)

Routinely look for signs of tread ware or damage
