Tyre Expiry

Road Safety And Aspects Of Tyre Safety

Studies of tyre safety show that maintaining proper tyre pressure, observing tyre and vehicle load limits,and inspecting tyres for cuts, slashes, and other irregularities are the most important things you can do to avoid tyre failure, such as tread separation or blowout and flat tyres. 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 tyres.

 

Information You Should Know About The Tyres On Your Vehicle

 

  • Temperature Resistance
 
  • Traction
 
  • Tread wear
 
  • Max. Load Capacity /tyre
 
  • Speed Symbol
 
  • Manufacturing Date


Where you can find these information?

 

 

Temperature Resistance

These letters indicates a tyre's
resistance to heat.
From highest to lowest, a
tyre's resistance to heat is
graded as "A", "B", or "C".

Symbol Area

A

Hot Area

B

Normal Weather Area

C

Cold Area

Treadwear Number

This number indicates the tyre's wear rate. The higher the treadwear number is, the longer it should take for the tread to wear down. For example, a tyre graded 400 should last twice as long as a tyre graded 200.

Traction

This letter indicates a tyre's ability to stop on wet pavement. A higher graded tyre should allow you to stop your car on wet roads in a shorter distance than a tyre with a lower grade. Traction is graded from highest to lowest as "AA","A", "B", and "C".

Max. Load Capacity & Tyre Speed Symbol

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

Manufacturing Date

Tyre Expiry

Vehicle tyres are often given a 4-year validity period from their Date of Manufacture (DOM). [ not a legal stipulation] Thereafter, the tyre expires and may burst whilst in use.

How to find out whether your tyre 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 tyre is manufactured in the 26th week of the year 2003. *2699* this shows that the tyre is made in the 26th week of 1999.
Check all your tyres for safety purposes. Do not use expired tyres. They are likely to burst (especially when running in hot weather) because the rubber component may have hardened and cracked.

 

4002 means DOM is Week 40 of year 2002.
