Most of us drive motor vehicles on daily basis but hardly pay attention to one of the most vital parts of the vehicles - the tyres

Unfortunately, very few of us change this bad habit until it is too late 3

Expiry Date
Tyres expire 5 years after the date of manufacture. A tyre's expiry date is stamped on one side of it

5. Tyre Safety
TIRE SAFETY
A tyre's expiry date is indicated by a 4-digit number stamped on it
The number indicates the week and the year it was manufactured
The expiration date is 4 years after 5

This number indicates that this tyre was manufactured on the 7th week of 2007, which is the same as February That would place the expiry date on February 2011

Tyre Safety
Expired tyres are likely to burst when used, and this might result in very serious, or even fatal, accident
It is advisable to check our tyres and make sure they have not expired 7

8. Tyre Safety Tyre Pressure
Another important point that we miss many times is proper tyre inflation. Some vulcanizers will calibrate your tyres at 28 PSI and if you are going to travel they will, sometimes, bring your pressure down to PSI because they will “heat up on the highway and the pressure will come back up”. DO NOT ALLOW THIS 8

9. TIRE SAFETY
Tyre Safety
On the side of the tyre, you will find the maximum allowable inflating pressure for that specific tyre
Some tyres have a maximum pressure of 32 PSI, some are rated at 44PSI 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 9

10. TIRE SAFETY
Tyre Safety
Different tyres are designed for different pressures. You will find the maximum tyre inflation pressure as a small number next to the rim on the side of the tyre. Never exceed this pressure!
MAX PRESS ACCEPTABLE
32 PSI 28 PSI
44 PSI 35 PSI
50 PSI 44 PSI
(44 psi) MAX PRESS

Lower pressure increases tyre heat. Infrared photograph of tyres tested at high speed shows damaging heat increases as pressure drops 11

12. Tyre Safety Load Rating
TIRE SAFETY
Tyre Safety
Load Rating
The load we carry in our vehicles put strains on the tyres
Tyres have maximum load rating designed for them
Exceeding the maximum load can cause failure and this may result in accident 12

The speed rating of a tyre is indicated by a letter next to the load index. Adjacent table shows the speed ratings in Km/h & Mph 15

Tyre Size
Many of us have bought tyres in the past and we are asked the sizes we just read them from the old tyres and give to the persons at the tyre shops. But, what do those numbers mean? 16

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” 19

20. TIRE SAFETY
Tyre Safety
Treadwear
The treadwear number indicates the rate at which the tyre wears out. The higher the treadwear the longer it should take the tyre to wear out. Hence, a tyre graded at 400 should last twice as long as a tyre graded at 200 20
