Most of us operate motor vehicles on a daily basis and hardly ever pay any attention to one of the most vital parts of the vehicle - the tyres.

Unfortunately very few of us change this bad habit until it is too late.

Did you know that tyres expire 4 years after the date of manufacture and this date is stamped on the side of the tyre?

TYRE SAFETY

It is very easy to find out what the expiration date is on a tyre. If you check on the side, you will find a 4 digit number stamped on it. This number indicates the week and the year it was manufactured, therefore the expiration date will be 4 years later.

This number indicates that the tyre was manufactured on the 7th week of 2007 (or February 2007); that would place the expiry date at February 2011.

TYRE SAFETY

If we use expired tyres these are likely to burst and result in a very serious or even fatal accident. It would be good practice for us to check our tyres and make sure they have not passed their expiry date.

Another important point that we miss many times is proper tyre inflation. Most of the petrol stations will calibrate your tyres at 28 PSI and if you are going to travel they will even in many cases bring your pressure down to 24-26 PSI because they will “heat up on the highway and the pressure will come back up”.

On the side of the tyre, you will also find the maximum allowable inflating pressure for that specific tyre. Some tyres have a maximum pressure of 32 PSI, some are rated at 44 PSI and some even at 50 PSI. Check your specific tyre to see what the maximum pressure is; it is an acceptable practice to have your tyres a few pounds below maximum allowable pressure but not too much.

Different tyres are designed for different pressures and you will find your maximum tyre inflation pressure on a small number next to the rim on the side of the tyre. Never exceed this pressure.

Lower pressure increases tyre heat. Infrared photography of tyres tested at high speed shows damaging heat increases as pressure drops.

TYRE SAFETY

Another important point to consider is the load we put on the tyres. Many times we overload our vehicles without paying any attention to the strain this puts on the tyres. Exceeding the maximum load rating on a tyre may also lead to tyre failure and could result in an accident.

Many of us have bought tyres in the past and when they ask us the size of the tyres, we just read it from the old tyre and give them to the person at the tyre shop. But what do those numbers mean?

Traction is a tyre’s ability to stop on wet roads. A higher graded tyre should allow you to stop your vehicle on a wet road in a shorter distance than a tyre with lower grade. Traction is graded from highest to lowest as ”AA”, “A”, “B” and “C”

This number will give you the rate at which the tyre wears out, the higher the treadwear the longer it should take for the tyre to wear out. Hence, a tyre graded at 400 should last twice as long as a tyre graded at 200
