The tyre is a major part of an auto-mobile as it’s the part that has constant contact with the road. So it should be handled with care, but besides gauging the air pressure, many people do not know how long it takes before a tyre is unfit for the road. A 2006 survey in Britain showed that only 4% of consumers are aware that tyres become more dangerous as they age. Tyres are made from rubber and as they age, they undergo a chemical process called oxidation caused by exposure to oxygen. This constant exposure to oxygen on the long run hardens the rubber, reducing its flexibility which could lead to eventual breakdown of the tyre under normal stress. Other factors that can cause tyre wear, thereby reducing its quality are:

Driving Style –Aggressive cornering and brakes could affect the tyre. So drivers are advised to drive with care to get optimum experience from the tyres.

Position –The position of the tyre also influences it. Front tyres wear faster than the rear tyres due to Steering.

Speed – high speed driving involves more friction between the tyre and the road, thereby increasing the temperature and on the long run wearing the tyre out.

Load- Cars have a stipulated amount of load they can contain at a particular time. If this partulcar load is exceeded it could lead to wear of the tyre.

Pressure – Both under-inflation and over-inflation of a tyre could lead to wear.

Alignment – an uneven alignment and bad shock absorbers have negative influences on the tyre, leading to wear.

Producers always boast that you can get a minimum of 20,000 miles on newly purchased tyres so many people always keep a track of their mileage. Although there is some truth to this, tyres can still become bad without hitting the 20,000miles benchmark. Many people are unaware of the 4-year expiry date on tyres or the Date of Manufacture(DOM) that appears on them.
How then do you find out if a tyre has expired?


1. Check the tyre identification number for four numbers which appear like this (*0204*). There is an asterisk at the beginning and end of this serial number (some tyres don’t have asterisk).

2. The first two digits are the week of production, while the last two represent the year. Meaning the tyre was produced in the second week of 2004.

3. This means the tyre will expire in the second week of 2008.


Check all your tyres for safety purpose. Do not use expired tyres as they are likely to burst (especially during this hot weather) because they may have hardened and cracked.

ubecharles:
What of those that use toks tyers manufactured 10 to 20yrs ago

rollUP:


I know nothing bou tyres but I think in the example u made the 0204 stands for second month in 2004. I might be wrong oo but it's just what I think due to normal groceries and drinks expiration date.

possibilita:
nice,but tires are normally designed to have an average life spam if 10years don't knw when it was reduced to 4 yrs .

golddust6000:
OP you are a big lier, that number symbolise the size of your realm not expiring date, i work in tyre manufacturing in germany

davodyguy:
Doesn't really matter to some people and I'll tell the reason why
To a very careful and cautious driver, he would pay attention to the tyres and change them as and when due. However, using the tyres beyond 4 years doesn't mean the car will not move or have accident.

Take a look at Tokunbo cars that are over 10 years old, the tyres aren't brand new when we bring them into Nigeria. But will they have accident cosof tyres? Not necessarily.

The average life span of some machines are 25 years, but a Zord printing machine manufactured in 1970 is still working till date (2016) cos it has been overhauled and renewed as new.

Same way Aircrafts that are over 30 years old still flying in the air. Once adequate maintenance are done, everything's fine.

A 2 year old tyre can kill you due to a burst at a top speed of 160kmph on 3rd mainland bridge or other highway(s)

Just be careful to check the tyre PSI regularly as well as wear and tear. Once a tyre is bent from the wheel and its wearing out, change it

DEXTROVERT:
my tyres are alphabetically numbered not numeric....how do I read them

femi4:
You are wrong, the first two digits represent weeks. So 0204 is second week of 2004 and not February

ademoladeji:
Yes!

4yrs after the manufacturing date...

Most of us don't have time to check dem...

Moreso, what if the tyre has spent like 3yrs in stock before being sold?

tsephanyah:
if they wanted us to know, why can't thy write expiration date boldly

rollUP:


OK no problem with dat. But I don't think u understand. D op said it stands for second week in 2004. Me I'm saying it might stand for second month in 2004. The ish here is the 02 not the year like u implied.
