Our roads have been turned into battlefields. Lawlessness reigns supreme. Lives and property are
destroyed or lost without anyone losing sleep.
What I am referring to as roads are in most places stretches of land where manholes and potholes
compete for prominence. Sometimes mother luck smiles at us and we have strips of tarred areas
reminding us that once upon a time there was a road or a semblance of a road there.
Imagine dodging these craters and competing with people totally drunk yet in charge of a
steering wheel. Add a good dose of noise pollution from blarring horns and do not forget our car
tyres and road (or is it battle-field) worthiness of our vehicles.
Today we have Abenaa Antwiwaa Adusei (AA) who will tackle a vital part of our road safety
that we so often take for granted. Abenaa practiced as a nurse for six years before pursuing an
MSc in Occupational Hygiene, which in her opinion positions her to prevent injuries and ill-
health rather than wait to see patients at the hospital.
KCE: I am glad you made valuable time to share vital information with my readers.
AA: Same here. Thank you and your readers for allowing me to share this with you.
KCE: You are extremely passionate about etiquette and safety, what motivates you?
AA: The results of ignoring safety is always expensive, in terms of cost of compensation,
repair/replacement, loss of corporate image, accidents, disability, loss of lives and properties.
All these are most of the time easily preventable by observing safety rules, hence my extreme
passion. The popular saying is that ‘prevention is better than cure’ and I totally agree; why cure
at an expensive price when you can prevent with just a little!
KCE: Our roads could be described as death traps, dodging these holes has caused many
accidents and people have been maimed or precious lives lost. What is your take on safety on our
roads?
AA: Safety on our roads, indeed, leaves much to be desired. A lot is being done by the National
Road Safety Commission to improve safety on our roads but there is more room for
improvement. Almost everyone has lost a family member or a friend or knows someone who has
been disabled through road accidents. So many factors come together to contribute to poor safety
on our roads. Unfortunately, the next victim to poor road safety could be you or me.
KCE: You believe that beyond the poor roads, drunk drivers, poor sight etc., there is another
major factor that makes life on our roads even more dangerous. Kindly enlighten us
AA: Generally, causes of road traffic accidents (RTA) have been grouped into 3 main
components; the human factor, road/environment factor and the vehicle factor. Human factor
deals with actions and inactions on the part of drivers, passengers, pedestrians and road safety
law-enforcement personnel. Road/environment factors deals with the nature and designs of our
roads, lighting systems, traffic calming measures, speed limits, pedestrian facilities etc. Vehicle
factor takes a look at design/size of the vehicle, roadworthiness, braking system, tyres,
restraints/seatbelts etc.
KCE: Which of the factors you have listed is in your opinion the most important?
AA: According to an approach called the Human – Environment – Vehicle Interface which
looks at the percentage contribution of each of the factors as well as their combinations to RTA;
human factor alone is said to contribute about 57%. This approach makes this factor most
important but I guess we can critically look at the vehicular factors with specific emphasis on
tyres.
KCE: Which of the factors can easily be corrected with our new found knowledge?
AA: Human factors could be improved upon with continuous education, this may take some time
but a simple vehicular factor like poor condition of tyres could be corrected easily. It does not
take much to do this.
KCE: Have we lost the fight to have safe roads even before we started?
AA: Yes, to some extent but I guess there is hope. We all have roles to play.
KCE: What practical steps may be taken to ensure that our car tyres are much safer?
AA: i. Proper Inflation/Pressure: Maintaining proper air pressure is the single most important
thing drivers can do for their tyres. It is important to check air pressure regularly, to make sure
tyres are neither under- nor over-inflated. One can find the correct tyre pressure for one’s vehicle
in the operating manual and in most cases either under the fuel cap, on the inside of the door or
glove compartment. Correct pressure values are often different for front and rear tyres and are
higher for fully loaded vehicles.
Under-inflation causes increased tread wear on the outside edges (or shoulders) of the tyre. It
also generates excessive heat, which weakens components and reduces tyre durability. It reduces
fuel economy by increasing rolling resistance – soft tyres make vehicles work harder.
Over-inflation is also detrimental to the tyre. Too much air pressure causes the center of the
tread to bear the majority of the vehicle’s weight, which leads to faster and uneven wear. Any
kind of uneven wear will shorten the lifespan of tyres.
ii. Balance & Alignment: This ensures the safety of the driver and the performance of the
vehicle.
Unbalanced tyres cause road vibration, which leads to driver fatigue, premature tyre wear. Tyres
should be balanced when they are mounted on wheels for the first time or when they are
remounted after a repair. They should be rebalanced at the first sign of a vibration or shimmy,
and should be balanced at least once a year, regardless. A vehicle is said to be properly aligned
when all suspension and steering components are sound and when tyre and wheel assemblies are
running straight and true. Proper alignment is necessary for even tread wear and precise steering.
iii. Regular Rotation: Regular rotation is necessary to maintain even tread wear.
There are several methods of rotation. For most vehicles on the road, tyres from the rear axle are
moved to the drive axle and crossed to opposite sides of the vehicle. The tyres from the drive
axle are moved to the rear, but remain on the same sides. This is known as the “modified X”
pattern.
For four-wheel-drive vehicles, it is recommended to switch all four tires, both from side-to-side
and in axle position.
If no rotation period is specified on the vehicle owner’s manual for the manufacturer’s rotation
recommendations, tyres should be rotated every 5,000 – 8,000 miles. Four-wheel-drive vehicles
may require rotation as soon as every 4,000 miles.
iv. Visual Inspection/Tread Depth: Take a look at the treads for any sharp objects that may
have punctured the tyres. Even if the puncture is not deep enough to flatten the tyres
immediately, the cracking and pitting caused by smaller punctures can eventually worsen and
lead to problems down the road.
Look at the wear patterns on the treads as well. Excessive shoulder wear can indicate under-
inflation, while wear to the center of the tread can mean over-inflation.
Tyres have tread wear indicator bars moulded into the tread. When the tread is worn down to
where you can see a solid bar of rubber across the width of the tread, it is time to replace the tyre.
Another method for checking tread depth is to place a coin (20 pesewa) in the tread groove, a
tyre with a good tread depth should admit about half of the width of the coin.
Tyre pressure should be checked when the tyres are cold, at least once a month and before long
journeys or when carrying heavy loads.
v. Repairs: It is important to know when to repair a tyre and when it should be replaced. If a tyre
loses its air pressure, it must be removed from the wheel for a complete internal inspection to be
sure it is not damaged.
Most punctures, nail holes or cuts up to 1/4 inch can be repaired by trained Technicians as long
as the damage is confined to the repairable tread. DO NOT repair tyres with tread punctures
larger than 1/4 inch, or any sidewall puncture. Also, never repair tyres which are worn below
1/16 inch of tread depth.
Replacement of tyres: Tyre age is also crucial to safety on the road. Even though tyre life
generally depends on service conditions and the environment in which tyres operate, some
vehicle manufacturers recommend that tyres be replaced every four to six years regardless of
use. Always, check the owner’s manual for specific recommendations for your vehicle.
Can you tell when your tyres were made? The date tyres were manufactured are indicated on
the sidewall of the tyres in the form of four numbers usually preceded by the letters DOT. The
four letters represents the week and year of manufacture. In most instances, there are 12 numbers
after the DOT but the first four numbers are considered in identifying the age of the tyre. For
example, DOT 1015 or DOT 1015 243/47R18 means 10th week of the year 2015.
KCE: Are you willing to meet with companies, groups of people etc. to promote this campaign
on safe tires?
AA: Oh yes! I cannot keep this to myself. Safety on our roads is a shared responsibility and as
long as individuals, groups of people and companies are willing to get more of such knowledge, I
am willing to steer them towards road safety. I intend to work in collaboration with National
Road Safety Commission too.
KCE: Is there a slogan on Tyre Safety you would like to leave us with?
AA: Tyre Smartness Saves Lives, Play Your PART (P- Pressure, A- Alignment, R- Rotation,
T-Tread)!
KCE: What are your final words on tyre safety?
AA: We all sit in cars, be it our own or as passengers. Cars move with tyres and the safety of
tyres plays a significant role in reaching our destinations in time, delayed, dead or alive. Hence,
let us all be tyre safety conscious and always remember to play your PART in order to be tyre
smart!
KCE: Thank you very much Abenaa. Almost everyone comes into contact with a car tyre on a
daily basis and will find these tips extremely beneficial.
AA: Thank you for hosting me! Let us all join hands to promote tyre safety in order to save lives,
properties, disabilities, avoid litigations and compensations. Let us always remember that
generally, Safety, Health and Environment incidents are rare but they have huge impacts, when
they hit us, they hit us badly. Thank you.
