Car Tyre Pressure: How to Check It and Get It Right

Getting car tyre pressure right takes five minutes and protects your grip, your fuel bill and your tyres. This guide shows where to find the correct number, when to measure it and what goes wrong when pressure is off.

This matters in India because long highway trips, heavy loads and hot weather all change what your tyres need. Bridgestone India notes that the right pressure depends on the car, the tyre size, and the passenger and luggage load.

Where to find the right car tyre pressure

Also, look in the owner’s manual, on the driver side door sticker, or on the fuel lid, according to Bridgestone India. Honda’s owner’s manual also points to the driver’s doorjamb label. Do not use the number printed on the tyre sidewall, because that is a maximum, not your car’s setting.

When to check

So, check when the tyres are cold. Honda defines this as the car parked for at least three hours, or driven less than 1.6km. Hot tyres can read 30 to 40 kPa higher, so a warm reading can fool you.

Bridgestone suggests a check every two weeks or before a long trip. Honda says to measure all tyres, including the spare, at least once a month. Still, even good tyres can lose 10 to 20 kPa a month, as Honda’s owner’s manual explains.

How to check, step by step

1. Park the car and let the tyres cool.
2. Remove the valve cap and press a calibrated gauge firmly on the valve.
3. Compare the reading with the door sticker value.
4. Add or release air, then recheck and refit the valve cap.

Valve caps help keep dust and water out of the valve core, so always put them back.

What low or high pressure does

However, low pressure wears the outer shoulders faster and raises fuel use. It also weakens braking, especially in the wet, and builds heat that can cause blowouts at speed. High pressure wears the centre of the tread, reduces grip and gives a harsher ride.

Common mistakes

• Judging by eye: a tyre can look fine and still be off.
• Checking after a long drive: hot readings run high.
• Forgetting the spare: it can be low when you need it most.

Bridgestone also says nitrogen reduces how often you must top up. While you are at it, make sure your papers are in order, such as a valid PUC certificate.

FAQ

What is the right tyre pressure for my car?

Therefore, it is on the driver side door sticker, in the owner’s manual, or on the fuel lid. It depends on the model, tyre size and load.

Should I check tyre pressure hot or cold?

Also, check cold. Honda says hot tyres can read 30 to 40 kPa higher, which gives a false reading.

How often should I check my tyres?

Bridgestone suggests every two weeks or before a long trip. Honda says at least once a month, including the spare.
