Introduction Car tyre pressure plays a vital role during a drive to ensure smoothness and fuel efficiency of the ride. Keeping the car tyre pressure at inappropriate levels can have an adverse impact. It is a good practice to get the tyre pressure checked at nearby petrol pumps every 15-20 days or at least once in a month to make sure that it is proper. Both very low and very high tyre pressure is not good for the car and it should be set as mentioned in the car manufacturers manual.
Effects of low tyre air pressure Below are some undesirable effects of maintaining lower than normal tyre air pressure.
Effects of high tyre air pressure Just as the underinflated tyre can be harmful same is true with the overinflated tyre. So tyre pressure should not be kept high than the normal thinking that very high tyre pressure is good for the car. Below are some adverse effects of maintaining too high tyre pressure.
Dos and donts of maintaining Tyre air pressure Depending on car manufacturer, type, size and model manufacturer recommended tyre pressure varies from 28 PSI to 36 PSI approximately. So attempt should be made to stick to these levels. Below are some points to be kept in mind while getting your tyres filled.
Accordingly, it is more advisable to fill your tyres when the weather is comparatively cold. If the tyre is filled when temperatures are high it will show higher pressure. When your car returns to your home parking lot and cools down tyre cold pressure will fall below the normal value. For example, it is more advisable to fill your tyres in morning or night rather than afternoon due to the temperature effect.
Conclusion Though maintaining tyre air pressure may not seem an important part in vehicle maintenance it is very crucial in prolonging the life of your car tyres and also ensuring good ride quality, control, lower maintenance costs and proper gas mileage. Hence it can save you quite a bit of money if you adhere to the guidelines regarding maintaining your car tyre pressure.
An in-depth practical article for car owners, most of us fill petrol/diesel but ignore checking tyre pressure, frequently by being lazy or seeing the queue at the air pump. Some service station staff say no need to check pressure for 2-3 months for a new car. Sounds like it is not true.
In winter, the author recommends to fill a little higher for cold tyres, does this logic apply to the winter season and vice versa in summer.
Are the pressures same for tubeless tyres and Nitrogen filled tyres? ( many gas stations advertise nitrogen is better than air in terms of tyre life and mileage efficiency).
There are many portable tyre air inflator units in the market for a couple of thousand rupees, can we use it regularly to check the pressue and top up or is it better to go to the gas station air pumps?
1. Ensure that the attendant filling the air puts back the ‘tyre valve caps’ on all four wheels after he fills the air
2. If the air pressure in the tyres is less than what is recommended by the manufacturer then there is also the chance of the bottom of the car hitting speed breakers, especially if the car is loaded, with extra passengers or luggage
3. As advised by the author air should be filled when the tyres are cool. This is because air expands when it is heated and in hot or warm weather the air would expand. Similarly, the air in the tyres would expand if the car has been driven a long distance. In such cases, the pressure gauge will not show the right psi readings
4. Air pressure must be checked at least once a month
5. If you are hard-pressed for time, to queue up to have the air pressure checked, then it is best to invest in a pressure gauge and foot pump (psi tye pump)
Tyre pressure has its effect on the vehicle as well as passenger in various ways.
I have some experience from the private transport buses in Kerala. They always keep the tyre pressure to the maximum. This helps them to sped the bus fast and get pick up fast. As such it saves them fuel.But for the helpless passenger even i the wheel runs over a small pebble, the shock and shake will be too much and back breaking.
But keeping pressure low also is not good.They have to be kept at optimum level. It is better to adhere to the manuals and instructions given by the manufacturer.
Cars are used for a comfortable and pleasure ride. Hence it is very pertinent to keep the tyre pressure to the optimum level.
I have seen many experienced and duty conscious drivers in the state transport buses checking the tyres before starting the vehicle. Why? even when we were riding bicycles we used to check tyre pressure by pressing with hand.
Always maintain recommended tyre pressure. Suppose it is recommended 36psi, fill 36psi do fill 40 psi. You can check your tyre's recommended and brusting pressure it is writte non tyres.Compressed air expands inside the tyre.
If you often go on highway better you should fill your car tyres with nitrogen. Nitrogen does not expand much as compressed air so brusting of tyres athigh speed can be eliminated by Nitrogenfilling inthe tyres.If Nitrogen is filled in the tyres, tyreswill have green colour caps and compressed air with black caps.
