Tyre Safety
Maintenance of tyres is very important to vehicle safety and it is imperative for drivers to ensure that they inspect tyres before driving vehicle on the road.
LTA Chief Executive Officer Samuel Simpson said damaged or excessively worn tyres and improper alignment of tyres pose huge risks not only to drivers but to other road users as well.
LTA is advising drivers to be mindful of the following important safety tips relating to tyres:
Wear
Please ensure that your tyres are not damaged before driving on the road. Tyre wear is caused by a combination of factors, including tyre construction and quality, weather, air pressure, etc. Of all these factors, air pressure is most controllable by users.
Rotation
Regular tyre rotation extends the life of your tyres, saving you time and money. For rotation, each tyre and wheel is removed from your vehicle and moved to a different position. This ensures that all of the tyres wear evenly and last longer.
Alignment
Proper alignment ensures that your vehicle handles correctly and will help increase the life and performance of your tyres. Failure to keep your vehicle's wheels properly aligned can result in: excessive tyre wear, irreparable tyre damage, excessive fuel consumption and unsafe handling.
Tyres should be checked monthly for signs of irregular wear in both tread and shoulder areas. Irregular wear may indicate under-inflation or tyre damage, or the need for wheel alignment or suspension repairs. A wheel alignment is also mandatory when a replacement set of tyres is fitted to a car.
Three key elements involved in wheel alignment that affect the vehicle's performance are:
Balance
Incorrect balance is the largest cause of vehicle vibration. A wheel is out of balance when one area is heavier or lighter than the rest. This can cause uneven treadwear, increased vibration, and increased stress on the front-end parts that may cause them to wear prematurely.
You should have your wheels balanced and aligned:
• whenever a tyre is replaced
• at the first sign of vibration or irregular treadwear
• when a balance weight is moved or removed
• whenever you purchase new tyres
You should check air pressure regularly because tyres function properly only when they have the correct level of air pressure. If the air pressure is low or high, tyre function deteriorates, resulting in tyre damage, and possibly an accident.
Pressure
Manufacturers' recommended tyre air pressure levels are indicated in your vehicle's user manual or on the inner part of the door. They vary slightly among various manufacturers.
Helpful Tips
When driving for an extended period of time, it is recommended that the air pressure be upwardly adjusted by about 4 psi.
Always look for bulges, cracks, cuts, penetrations and abnormal tyre wear, particularly on the edges of the tyre tread, which may be caused by misalignment or under inflation. Also check spare tyres. Have an experienced tyre technician immediately inspect the tyre if any such damage happen. Continuing to use a damaged tyre could result in tyre failure causing serious injury or even death.
Factors that can lead to accidents include:
Shallow Groove Depth: when groove depth reaches 1.6mm, tyres are prone to slip and can easily blow out from hitting sharp objects.
Improper Air Pressure: when used with low air pressure, tyres generate high levels of heat. As a result, rubber and cord separate from each other, the cord is disconnected and the tyre is blown out. Also, the edge of the tyre is quickly worn away, shortening tyre life. On the other hand, when the tyre has too much air it becomes tense and is easily blown out or cut by external impact.
Scarring: when tyres run with nails, stones or other objects stuck in the tread groove, they can become flat or blow out. If the scar risks reaching the carcass, the tyre must be immediately replaced.
Abnormal Wear: excessive or deficient air pressure and poor car wheel maintenance abnormally wear tyres. Check tyre air pressure, alignment, and rotation regularly, while refraining from improper driving habits such as sudden accelerating, braking and cornering.
Wheel Damage: uneven load distribution on tyres due to wheel damage may create friction between the rim fringe and the tyre bead part, generating heat high enough to damage the cord and cause tyre blow out.
Road Safety is everyone’s responsibility.
