Tyre pressure

goldlemontree

Hello, just wanted to ask whether you should pump tyres using recommended psi engraved on the actual tyre, or recommended tyre pressure for car make/model in general? I usually just look on each individual tyre and pump according to what it says on that, is that acceptable? Thanks

Are you serious?

You should use the values in the handbook or on the sticker in the door jamb (usually). The recommended pressures may vary depending on load.

The pressure marked on the tyre is the maximum pressure that that tyre can be inflated to,

The handbook will usually give two sets of pressures for heavy loaded and light loaded, some cars also change the pressures required for the speed you will be going also some cars have different pressures for the fronts and the rears.
This is very important and need regular checks, once a week minimum

That being said, for the most part it isn't that important how hard you inflate them.

But some cars are very sensitive to tyre pressure changes. And not always the obvious suspects. The worst culprit for this I've had was an HC Vauxhall Viva - a car that wasn't particularly renown for sophistication and handling. 3-4 psi low and it wandered, 3-4 psi high and it, for want of better words, skipped and skittered on bumps and road imperfections.

What a complete load of nonsense and really bad advice. Incorrect tyre pressures, whether widely under or over can have a detrimental affect to your tyres, economy, driving experience and overall safety. Do not listen to this guy!

It's not ridiculous. Your tyres do not have to match the recommended pressures. Its up to you how you inflate them. Its not going to destroy the car. You're just being drama queens.


Yes of course changing the pressure can affect economy, ride, handling, etc. all I'm saying is that different people have different preferences and you are not required to stick to the recommended pressures.

Looks like the world and his wife disagree with you.

is it dangerous to over inflate tires :rotfl:

Did you actually read any of the results...


It really is not "dangerous" any real sense of the word.

I'm guessing you didn't.

"When your tyres are over-inflated your car will not be able to perform as well as it should. They will not be able to get a good grip on the road and this can have effect not only on the safety of your car but in the performance and mileage you get from your car each day. It will cause the tyres to wear improperly, making them dangerous for you to drive on. Over-inflated tyres may even be more likely to puncture, causing you to get a flat or a blowout. This can be very dangerous if you are travelling at faster speeds"

But you crack on.
