How to pick the right tyre?

1. Can I get upsize my tyre?

Pick the tyre that is being approved for the use on your vehicle. You will find no reason to buy tyre with speed rating that exceeds your car’s top speed, because that will cost you more with no benefit. Choosing a bigger tyre might make your car looks better, however, there are plenty of disadvantages. It will affect the fuel economy, braking system and even performance.  Larger wheels also cause discomfort to your driving experience since bigger tyre indicates the size of the tyre’s sidewall shrink to maintain the tyre’s overall diameter. It will lead to lower shock absorption and more road noise.

2. What tyres are suitable for Malaysia weather?

Summer tyre is suitable to be used in Malaysia. In this tropical climate country with heavy downpour and hot sunny day depending on the monsoon season, we can use either the regular tyre or the wet tyre. They deliver excellent driving and braking performance on wet and dry road conditions, the tread pattern ensures that the tyre is able to grip well to the tarmac road as rigid as possible at all time. They have high water dispersion to rapidly expel rain along it’s tread away from the contact area with the driving road. Summer tyre is usually robust, it is able to tackle damaged roads and potholes as long as you are driving in low speed. Also, their soft rubber compounds are designed to be responsive especially during steering, accelerating and braking in keeping the vehicle stable and the driver in control.

3. Can I purchase used tyre instead?

Yes but we would not recommend it. Bear in mind that tyres are the only contact your vehicle has with the road and grip plays an important role. It is not that the used tyre is always unsafe, however, used tyre may have defects or tread wears that one may not able to see, however you can test the depth of the tread by using coin (refer to image below). If the treads are still good, inspect the tyre for any defect, it may be tricky, not if you come across some good Samaritans that could identify the defect for you. However, in most case, patched tyre and worn tyre are not recommended as it will likely to skid on wet surface. Therefore it is always no harm to splurge a little more for new tyre for a peace of mind.


One should not take your car tyre for granted as it could either save you or hurt you. Pump your tyre with correct pressure will impact how long a tyre last, gas them before they are flat out. You can always refer to your vehicle manual in the glove compartment or the tyre information sticker on the driver’s side door. If you are still uncomfortable to pick your own tyre, seek help from the professionals.
