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

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

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

Another important point, at most of the gas stations they calibrate your tyres at 28 PSI and if you are going to travel in many cases they bring your pressure down to 24-26 PSI because tyres will “heat up on the highway and the pressure will come back up”. DO NOT ALLOW THIS

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 for your tyres, 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 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

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

The speed rating for which a tyre is designed is indicated by a letter next
to the load index, adjacent table shows the speed ratings in Km/h &
Mph.

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 TRACTION
Traction is a tyre’s ability to stop on wet pavement. 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”
