Inflation pressure

[User12343]

hi brudders,

 

typically if the tires are designed by the manufacturer to be inflated with XX PSI, what is the max PSI in excess of XX that can be pumped in w/o bursting? is there any guideline that one cannot exceed by, say 5% of the inflation pressure? cos always chua chua when it comes to topping up the air even wif preset pressures.

 

thanks

Hi! there, User12343,

 

At the side wall of the tyre, it's stated the max. load, max. pressure, for the tyre, if there isn't, then the tyre is not meant for the road.

Hi fellow drivers..

 

if the stickers on the car indicates the cold tire pressure to be 21 kgf/cm2, does it also means 21psi? If so, what would be the pressure be in Kpa??

 

Thanks...

cheers..

[Turbobrick]

U sure it's 21kgf/cm2? That's only 4.3psi!

[Michel]

Oops....it's 2.1 kgf/cm2.....i believe

 

i managed to covert it to about 29.87 Psi...

Please enlighten me, what does Kpa stands for?

[Magfocus]

Kpa? Kilo Pascal??

[Turbobrick]

Kpa? Kilo Pascal??

 

Correct! U've won a life sized Barney doll!!!

[Michel]

Thanks a million, maties..

 

Hmm....would i be able to pump moi tires using Psi with the new Mobil digi pumps then? Sorry to bother...cos i've been pumping estimated Kpa throughout my driving stint.

Go ahead and load 30psi into your tires based on the digi-pump reading....should get close enough. Best if U could invest in a Stetho Gauge to confirm your tire pressures after pumping. Remeber to pump when the tires are cold (at least try to get to the nearest petrol kiosk from your home in the morning)

Is it a new car u driving? btw.. what car are u driving?

Pumped my under-inflated tyres this morning....hmm, seems to be quieter and less bumpy on the road, or is it just a psychological effect?!

Hi! there, Michel,

 

Usually, I'd pump my tyres the night before to stated 36psi, then in the morning, check the tyre press., set it to 32psi. Invest in a good tyre press. gauge, like doc, I use the Bluepoint gauge which has a bleed button, very convenient, bleed till the press. is reached. I think I'd use 34psi after I monitor my tyres, as one of them seems to have a tiny leak.

Think what u feel should be that your steering is lighter.... as for bumpy-ness.. that'll depend on what road u travelling on and your tyres.... think your turning would become more responsive too.....
