ok this will be a noobest question ever,

have u ever wonder what the right pressure for your tire? and lets say u have changed ur tyre size and also the sticker on driver door is not available

how should pump the tyre to pressure? pump it to max pressure stated on the tyre itself? but ive heard that temperature of the weather and also the tyre itself may effect it

also usually front tyre require more pressure then back tyre, why is that? engine location? front tyre need maneuver?

so the question remain, what the best pressure for your tyre?

front 210 rear 200...

what make u say this? isnt every car have different tyre pressure due to its weight and also the tyre size itself?

If your car has standard thick tires 200 should be enough. But it won't hurt if you put 220 or so. More pressure on the front tire if your car is FF because there's more weight in front. Actually up to you how much you want to put. It's either you want slightly better fuel economy or a better ride but i think the difference is small.

Don't pump max. That's just mad.

standard pressure for almost any car...n ure driving a neo right...

Can always follow what the tyre stated...
But for a standard cars, 220-230 is not a problem... But have to know that, higher pressure will result to braking issues.....

so if i want better FC should i pump slightly lower then better ride? is that wad u mean? i know 1 or 2 bar wont hurt but what is the best ?

i got experience before with a company car, the driver just pump using the max pressure stated on the tyre and pump during the afternoon i just sked the tyre will burst anytime


yes maybe u are true .. but i cant just pump kancil pressure into a isuzu dmax correct?

and yes im driving neo ..

dont over pump your tire.
your tire will not explode suddently...but from my experience, your tire will 'bengkak' 1st.

this is the sign of the inner thread failure.

if continue driving, then i think the tire will burst.

ok i correct my statement...

its standard pressure for almost all proton cars with campro engine...

want elaborate summore ka? how i know? i drive a gen2...used to use 205/40/17 i pump that pressure...used to use 205/45/16 oso pump that pressure...now using 195/55/15 oso pump that pressure...

can adjust a bit front 220 but pressure too high become road sensitive not too comfortable...

u ask basic noob question (which u admit to be noobest question ever) i answer and wanna argue more i feel wasting my time la...

If you use 40 or 45 series tires, you can pump around 250 or so. Pump harder for better FC or lower for comfort. It's just logic. There's also a difference in grip. More grip with less pressure. Too much pressure either explode or the center of your tire will be gone quickly.

Not sure if weight matters but my SV4 with 215/45R17 i pump 260/250.

er, why i use reading such as 29, 31. where got 220, 240. am i old?

the 29, 30, 31 is based on the PSI scale...

the 200+ is based on the KPA scale.

most pumps can change their scale unit.
some display both scale at the same time

some still prefer the old analog pump...me included

got la. that one is kpa reading. most pump got show both psi & kpa

Haha i prefer kPa and digital pump.

1. Never a nub question, I once saw a girl pump her Wira ...400, lucky I was right behind her and suggested maybe she want to pump a little less.

2. Pls let us know what car, general rule of thumb is around 220 for sedans as others have said.

3. If you are not sure, pump both front and rear same, some pump differently due to FF/FR, different tyre size, spirited driving, etc...

sorry if i hurt ur felling in any way .. this topic are meant for discussion therefore i ask for more details why u put that kind of pressure into your tire, yes maybe it was stated in the manual or the sticker on ur door but i just open this topic so we have more understanding what those numbers really mean and will it effect our driving, fuel consumption or even our safety, and basically our pocket which i believe with correct pressure we will have longer tyre life span


now i get the idea.. so basically harder = performance lower = comfort , now i get the idea when the tyre hard it will have better grip on the ground and when a bit soft it will bring back the rubbery of the tyre but if too low it will make ur tyre roll uneven.


no u too young.. old people use use those hundreds numbers on analog


400 on wira

even digital pump has the unit conversion button, just hold it and it will display psi reading

i pump 225kpa (33psi) for front and 205kpa (30psi) for rear, since the front of my car is dam heavy because of the driver and engine, and rear most of the time is empty

Added on March 24, 2011, 12:23 pmthe pump can go up to 400kpa? perhaps the wira got double tyre or something

so, much eh. my mech said only 31psi enough.

31psi is equal to 210kpa+-...

just follow what is written on side of tyre to be safe...
easy mah.... every tyre have this printed...



This post has been edited by mikicun: Mar 24 2011, 02:36 PM

then if ur tyre like above said max pressure 40psi (+-275kpa) u would pump in 40 psi meh?

u go pump max on ur 4 tyres?

keras & licin not good yo.

because all car has the same weight

speechless

aiyoo... thats the max pressure ur tyre can tahan la.. stupiak...

ur car tachometer write 240kph... ur drive 240kph all the way ka... stupiak..

just dont go over max la... take 60%-70% of max is enuff... save extra 30%-40% for extra weight, expansion from heat generated and other stuff la....

aiyoo...


** kalau kata bodo.. marah plak... nak kata pandai... nampak sgt bodonya.... susah2...**

bukan u tak tau kete kat pintu ade plak tulis recommended tyre pressure.

ur first reply didnt say 60-70% la bodo...u said follow what is written on side of tyre la bodo...

** sapa bodo ni? susah2..**

Hashhaha if i follow my tyre then I will be driving aroudn with 51 psi hahahhaha

go to workshop and pump la they can messure using pressure device...coz at petrol station u ll never get the real reading from the pump...coz everytime i finish pump i test with my digital pressure meter...the actual reading can different as much as +-20%

The correct way to check your tire pressure is during cold time, i always check my tire pressure during i warm up my engine in the morning. 31psi for front & rear on my 2.0 inspira

I thought tyre pressure is the same only difference is amount of air in the tyre

how exactly do u measure the amount of air if it not pressure?

can u please explain to noob like me?

lol.... chemistry time? you need physics too

Average just pump 31-33psi.

If u wan more comfort, then pump abit less. Will be better for braking too because more tyre surface contact with the road.

If u wan better fuel consumption, then pump abit more. Less tyre surface contact with road means less friction. But don't overpump, or it will compromise braking.

Normally if I'm pumping on a hot day or if I've driven to the petrol kiosk, then I'll pump a little bit more to compensate for expansion. So maybe abt 34-35psi.

er i mean you can inflate a lorry tyre to 32 psi and a bicycle tyre to 32 psi both have same pressure but amount of air is different

lol @ mikicun


aha yeah now that you word it this way it makes more sense.

My savvy i do 220front 200back. harder a bit than recommended

arent they using nitrogen nowadays???

I saw one wira at petrol station, 4 indian guys in car keep pointing the machine says it's spoilt already, they take turns to pump the tyres... i look at it, they are trying to put 40 (or 48 i don't remember) psi ... they didn't ask me, so i didn't tell them lo ...

any suggestion for 155/55/14 front and rear?thanks

Haha...got one time after i finished pumping air to my bike, then got one car waiting behind (cute girl)

so i gave the pump to her...i already increased the pressure to 32 psi...she looked at me (gave a weird reaction)...

she increased the pressure to 40 psi for here myvi

i just left after that, she made me look like orang bodoh

that time, i hoped that she doesnt involve in accident...

I'm not sure if that is exactly accurate.

It doesn't really matter. As long as you got the correct pressure, the correct amount of air will be in the tire. The question is, what should be the correct pressure?

What is your suggestion for 215 45 17 tyres ?

I normally pumped 250 for all 4 tires on my truck. Saw 1 aunty pumped 310 for her Honda Jazz. Wanted to tell her but she drove away.

I pump 235, because it will last longer between air pumping intervals.

Ya, for me also... last time i like to use manual but now i more like to use digital pump.

Easy and understanding.
