Do you know your car? If yes! Then you must know the tyre pressure in car too. If not, then sorry! You don’t know your car. Don’t agree? Confused? Is it important? What are the various types of tires? What should be the tyre pressure? Do tubeless tires need it? How to keep a watch on it? Do all car tires need the same PSI?  Let’s discuss it in detail.

Tires are one of the most important parts of a car which actually takes you from one place to another. They are the essential part of a car that faces the maximum wear and tear. That’s why tires need to be taken care of and so as to increase the life-span of it.

Do you know, what is the main reason for which your car tire loses its life? Maybe you don’t know. In fact, most of us (car owners) are not aware of it or don’t have the time to spend on it. We mostly depend on the mechanics for such things. A mechanic examines the car tire and does the needful. Basically, they use tyre pressure monitoring system to check and evaluate whether the tire pressure in car. Mostly, the tyre pressure gauge is used for this. It is a pressure gauge used to measure/check the tyre pressure in car or bike, etc. No doubt, it’s always good to treat your car from an expert (mechanic), but small things which can be looked at, should be looked at by us too.

Let’s jump into the main point – the necessity of tyre pressure in car. The basic and the most important thing about your car tire is the car tire pressure. Most of the time, we don’t or can’t realize whether the tires are well filled or not. If we are getting a kick start, we think, all good. But that might not be the case always. Because it is hard to differentiate two tires one being filled to the recommended PSI and the other being filled to a much lower PSI. That’s why it is always advisable to have regular check-ups on tyre pressure in car.

Why tyre pressure in car is so important?

Factor 1:

The first factor is the wear and tear of the tire. The longevity of a car depends on the correct tire pressure. Under inflating or overinflating can hamper the tire’s life-span.

An underinflating tire can cause faster heating since the area of contact (of the tire with the road) increases which in the long run may damage it.

Whereas, over-inflating can make the overall driving experience slightly unpleasant with extra bumpiness. Also, extra tyre pressure in car may expand the center of the tread more than required.

Factor 2:

Under-inflating or overinflating can reduce the overall mileage of the car. A tire loses its pressure continuously (around 1 PSI per month). A tire with 20% under-inflated can reduce the mileage by 20%. So, if the tyre pressure in car is not maintained, in a long run, there will be a noticeable reduction in mileage can occur.

Factor 3:

When the tyre pressure in car is not as per the recommendations, it can create problems in overall handling, can increase power consumption. Your vehicle will start emitting more CO2 which will reduce the performance gradually.

How the outside temperature impacts the tyre pressure in car

 The tyre pressure in car not only depends on how and up to what extent it is being used, but it also depends on the environmental temperature as well.

Summer

Does, tyre pressure in car needs to be looked at from the season’s point of view. Yes! Of course. The environmental temperature is slightly higher in summer than in any other season. We take care of ourselves and take many required precautions to keep ourselves safe from the extra heat/temperature. Similarly, the tyre pressure in car also needs to be taken care of.

The air present inside the tire gets heated and light in summer and so as it gets expanded. As per many studies/experiments, the tyre pressure in car goes up by 1 pound per square inch with every 10 degrees Fahrenheit increase in temperature. Just to keep you out of confusion and keeping the stats simple, if the car manufacture has recommended 35 Psi, in summer, you need to maintain around approximately 40 PSI.

Winter

Unlike summer, the environmental temperature drops down drastically. As per the nature of air, it gets contracted with less temperature. Since, in the winter, the temperature drops, the tyre pressure in car also contracts. As a result, the tire loses its size (contracts a bit). Maybe you will not notice this, but in winters, your tires are under-inflated.

Risks

Driving with under-inflated tyre pressure in car

Faster Wear and Tear

Keeping the experiments/studies and relevant stats aside, in general, under-inflated tires can reduce the longevity by 15%. It happens because the area of contact of the tires with the roads increases. As a result, the car or the tire has to face more friction.

Poor Mileage

Since the friction increases, the car has to use more power to regulate its performance. More power consumption means, more fuel consumption. So, in a long run, as a car owner, you may end up spending a huge amount on your fuel

Handling and Safety

It has been observed that driving with under-inflated tyre pressure in car can increase the braking distance. The steering response may change and can put the driver in trouble in handling it naturally. This is a case of a security issue.

 Driving with over-inflated tyre pressure in car

 Uneven tire and Faster damage

Extra, unwanted tyre pressure in car will make the outer layer uneven. The area of contact of the tire with the surface of the road will get disturbed as recommended. In a long run, it will damage the tires gradually.

Handling and Safety

Since the overall shape of the tire gets changed, the performance also gets disturbed accordingly. The steering response gets changed. The brake distance also increases. It will be difficult to adjust the vehicle in off-road and uneven paths. So, in the end, you will end up facing some safety issues.

Frequently ASKED Questions

What is the correct TYRE pressure in my car?

The correct tyre pressure can be known from the vehicle handbook. A manual or handbook given by the car manufacturer or by any manufacturer of any product (in general) is always advisable to follow or refer to. It tells about the recommended tyre pressure, under-inflation, and over-inflation limit as well.

As an individual, how will you be able to secure the correct TYRE pressure in your vehicle?

First of all, you need to know your vehicle. That can be done by going through the manual or handbook provided by the manufacturer. It contains all the correct, genuine, and recommended steps which need to take care of your vehicle overall. To be very specific, you need to know how much tyre pressure is recommended for your vehicle and you need to maintain that as much and as long as possible. To do so, you may need to check your vehicle’s tyre pressure frequently. You can correctly decide the required frequency the more you know your vehicle.

Is 40 PSI good tyre pressure?

Well, it varies from cars to cars. However, in general, 32 to 40 PSI (Pounds per Square Inch) is treated as a decent tyre pressure. But again, if a car manufacturer recommends 33 PSI, during summer and winter, it may vary. So, follow the manual to be very specific about your tyre pressure in car.

For a fully-laden car is it advisable to have TYRE pressure high or little less in summer on long journeys?

For a fully-laden car, it is better to have tyre pressure slightly higher. But again, that is not the case always. Especially, in summer, due to the extra environmental temperature, the air inside the tire gets heated and becomes lighter. As a result, it acquires more space and that’s why the tire becomes slightly bloated. So, keeping the recommended PSi or even a slight less than that can be okay for the fully-laden vehicle in summer.

Should front and rear TYRE pressure be the same?

Technically, it shouldn’t. The reason being, the engine situates in front. That’s why the front tires should have comparatively higher PSI than the rear tires. But again, follow the car handbook for your car or car model.

Can I drive on low tyre pressure?

Yes, you can! But this not at all recommended. Low tire pressure will low gas mileage. They may get heated at a faster rate and in the worst-case scenario, may burst too. It may create handling issues and will put you in trouble.

What should be TYRE pressure for cars in India?

The tyre pressure in car in India depends on various factors starting from the type of car, tire of road, size, weight, etc. That’s why different cars have different recommended car tire pressure. Below are some of the examples:

CAR NAME TYRE SIZE (TT)-TUBE TYPE   (TL)- TUBELESS FRONT (F) and REAR (R) RECOMMENDED TYRE PRESSURE
Maruti Suzuki Ritz 165 / 80 R 14 TL 32-36 PSI (F) & 33 PSI (R)
Maruti Suzuki S Cross 205 / 60 R 16 TL 33-36 PSI (F) & 33-36 PSI (R)
