How much u put in for your beloved tires?

Tires - 205 45 series - ???KPA / ??PSI

For me, when i was using stock wheels 14 inch, and now using 16 inch 205 45 series, i still put in 29 psi / 200 kpa. I believe this pressure is just right? Cuz most tire shops even recommended me to put in 28psi actually.

im put 30 psi...

my 13"...30 psi
my 15"...30 psi

At this moment I'm running 40psi front and 38psi rear on 215/17/45 and surprisingly it feels better and had better fuel consumption. I guess the my manual's rating of 33psi front and 32psi rear is outdated.

dont u feel stiff?the road signal too clear and uncomfortable?

bro, your tyre reading very funny here
45" on a Subaru

btw, what's the limit a tyre can take?

I'm already on stiff suspension and the higher pressure makes the steering feel even better since my car no longer bouncing on the tyres anymore. I don't like driving on soft suspension.. feels like a boat and you lose all connections to the road.

on 13", i put front 220kpa, rear 215kpa

on 15", front 230kpa, rear 220kpa

my own figure the 1 recommended by manual is like 10kpa lesser..

I've been 32psi front 30 rear on my old 185/60/r14
Its the same on my new 195/55/15

for city drive, front 31 and read 28 (PSI) if long distance up them by 3 PSIs

well.. is better to follow back the driver seat door there the label.. all about ur car tyre pressure..
i follow it when its still below 5km to petrol station morning drive..
after 5km i add in 1 more psi.. if 30 so i put in 31 or 32.. see how far i travel lor..
hot weather.. i put in 33 psi.. back 31..

walau eh! so high ar ur pressure...u sure ur tyres can take it?

i'll try ur settings later but i'm on 225/45/17, pumped used the recommended pressure

does that mean u always go to pump ur tyres?

100 kPa = 14.5 PSI

for my iswara, i pump 235 kPa front and 190~200 kPa rear for best FC. a bit bouncy lah, but got shiok lighter feeling and better throttle response. and when pumping above the recommended pressure, even if u forget to pump for a while, the pressure is still near or above the recommended level. if u pump ngam-ngam at the recommended level, when u forget to pump for some time it'll be way below it.

i know of a friend driving an iswara a/b who pumps 250 kPa for all 4 15" tyres

i'm running 34psi on my 215/45/17

300 kpa on all tyres...

Really can pump 40psi?! I has been using 30psi all this while, and keep wondering why my front tire always looks not fully inflated.

Can I do 34psi on 13"? Wira auto 1994 stock.

The max pressure rated for the Goodyear Eagle F1 that I'm using is 51psi. That's still a lot higher than the 40psi I'm using and even with the 10% increase after the tyre gets hot, I'm still safe.

That is nothing compared to my spare tyre. Recommended pressure is 60psi. Petronas pumps only go up to 58psi. I had to use Shell tyre pumps to fill it up to 60psi.

front: 32psi
rear: 30psi

I guess the wider tracks do compensate when filling up to 40psi. On a 15"-er, it'll start hinting a whee bit of grip loss, especially in the rain.


Had the same problem with my spare too Using one from a Waja.

At one instance, the entire tip/faucet popped off the tube while filling up! Had to quietly stuff it back into the tube & leave Pity the next quy using it

The wider tracks would aquaplane easier in the rain but the wet weather properties in the F1 makes up for it. So far, nothing comes close to F1 when it comes to handling in the wet and I just love it when I leave my fellow friends in AD07 in a spray of water during rain.

When i try 34psi front & 32psi rear into my 14". Wah...damn good the response. But suffered a bit when raining.

i put 32 in front 35 for the back ..imo handles bit better
all tires @ 225/60/R16 .

195/55/15, 240/230, front/rear

mine is 32psi for front & 34psi for rear coz I am driving FR car.

True, true. Closest rivals would be the Proxess
Really regret opting for non-rotational Ziex

front 38psi
rear 34psi

205/50/R16 Bridgestone Potenza Adrenalin RE001.

actually, i've monitored and tested quite a few petrol station air pumps. and most of the time, they are around 2psi lower that stated. meaning, when u set 38psi at the pump, the actual pressure into ur tyre is 36psi.

i with a michellin tyre pressure gauge the moment i finish pumping at the station itself. some petrol stations even go as low as 3-4psi.

therefore, alot of tyres are actually under-inflate.

conclusion, just set the pump to be 2-3 psi higher than ur desired pressure.

hope this helps.

250kpa all round. The fat 65 series NCT5 works best without the sidewall flexing and hopping around in corners.

30 psi sounds low for a normal street-driven car, probably dragging the engine a bit too. u can try higher pressures bit by bit till u find a best compromise that makes the car lighter yet not too bumpy

is it ok to put more air into old tyres?

pump at workshop "dry air" instead of at petrol station "wet air" . "Dry air" will maintain the tyre pressure longer in comparison.

dude u sure? i only running on 33psi for both my front (245/40/18) and rear (265/35/18). Can it really take 40psi??

40 psi is still within the limits of most tyres, but the more you pump, the closer it is to this limit, and therefore there's less safety margin to work with if the tyre hits a big hole or object on the road. just my 2 cents

Which ever station I go, I always see 29psi on the machine. So, I guess majority used 29psi.

Max pressured as marked on the sidewall is 51psi. Still a big margin to go...

i pump 32psi for all 4 tyres... car no bouncy/bumpy at all...

is it safe to pump 60psi on donut spare tyres? feel like will blow for a small tyre...
last time i saw a bangladash labour pump a tire for his trolley, the inner tube blow...

There's still plenty to go on my tyre. 51psi is max. I'd rather hit a big hole with a tyre full of pressure as the sidewall and rim will take less damage. Tyre will not blow out unless it was already damaged.

Added on February 22, 2008, 2:41 pmWell.. my manual says pump to 60psi before use. On the sidewall fo the donut spare also says pump to 60psi before use.

Pressure = Force/Area

where F = weight of 1/4 of the car
A = contact patch

Since the contact patch is less than the normal tyre, but the weight is the same it does require a higher pressure to sustain. Itu tayar cakap 60 u letak 60 lah. That tyre is built for that kinda pressure anyway

Rim damage/tumours are more likely to happen with underinflated tyres. U can see what happens when an underinflated tyre is pressed against the kerb stone if u park the car too close..

okie... just i worry that i never pump 60psi for any tyres before...

i dont want get kill bcos over pump the tyre and explode in front of me. long time i heard a news from newspaper that some1 pump his CASE (construction vehicle) tyre and get kill bcos the explosion...

next time will pump it, more than 1 year not pump air on it...

215/45/R18
34 front
32 back

me is 13 inch..

hehe..i pump like 250 most of the time..
so me centers sure botak early

where is it marked? easy to find?

tyre sidewall loh...
most of tyres will mention what is the maximum pressure...

but our tyres are to pump likely far frm da max..

optimum performance must like a 100psi less

omg u all pump so hard ah? for me 30 already pretty stiff and shakes the car already. Currently im using 205 45 R16 tires with 28psi pumped into all 4 tires.

it's 215/45-17 la~
diff ppl diff pronounce ma~
normall max pressure a tire can take is ard 45-51psi on cold pressure~

i agreed wit u~
but dun pray pray wit sime tire~
later get pregnent~ jus de spare tire 60psi~
i thing tat bangala over pump his tire~

me tires = 195/55/15

on 34psi

mine 155/70-12 front 36psi n rear 34psi~
then on my 185/60-14 front 34 n rear 33psi~

ehh.. sleep walker..
jst wanna check.. if i was to enter tracks with my 195/55/15 eagle f1 tires..

wat do u think the pressure should be??

higher or lower?? mind giving a figure?

you mention cold pressure rite? But after driving a while the pressure becomes hot isn't it?
So what's the max pressure on hot condition?

Im on 31psi front 28psi for the rear. Running on 235/45/17. Last time I tried 35psi once....abit too bumpy for me

1 year no pump air???

my parents told me to pump 28 on all 4 tyre, not sure how much the the stock tyre can withstand.

just checked...my Bridgestone MY-01 never mention the max pressure.
the rear tyres are RE711 and its 44psi max.
can I assume the same max pressure for the MY-01s?

lower~
25psi~

dunno wor~
tat tire neva state for hot pressure~

Adrenalin RE001 also 51psi max...tmr gonna try pump more a bit

Max pressure is max pressure, doesn't matter if it is hot or cold. Heat would increase the tyre temperature between 10-15 percent max as air does not expand too much.

AFAIK even the fattest, lousiest comfort slime tyres have a max of 300kpa. Low profile stuff usually can go much harder. stay below 80% max pressure for safety.

Added on February 23, 2008, 2:27 amThose tractor tyres are supposed to be soft and wobbly. Truck tyres run around 500+ kpa

Nothing will happen wan lah.. as long as u pump it to spec @ 420kpa..

PS. Personally I have seen a saga pump 400kpa, yes, 400, into 4 of his normal tyres (was waiting for him to finish using the airpump)

This post has been edited by ceo684: Feb 23 2008, 02:27 AM

I just pumped 33psi onto my 15" wheels and drove a while. Can feel the steering wheel much more easier to turn. Maybe less grip too, and a little more comfortable Next time might increase to 34psi

For me, been using 25-27 PSI on a R888 tyres.

400kpa on 175/70/13

He wanna get him/herself suicide....

My mechanic recommends me to pump at 28-30 psi for my stock rim 14" Falken 185/60/R14. After my Falken gone, will switch to Goodyear as Falken too "soft". but i always insist him to pump 31 psi front & 30 psi rear. it is recommended to follow your car manual or the sticker at your car door there.

I have never frequent petrol station air pump now, only go to workshop for "dry air"! Overpump, aquaplaning during raining/ explode is dangerous. An ex-colleague at petrol station overpumped his C*nt*nental S*m* but still within the tyre safety pressure, exploded during he was driving. Lucky he was ok & no accident occurred.

Dry air.. u meant nitrogen?

not nitrogen. workshop the air is through air compressor. my personal experience the pressure still the same psi after 1 month usage & no pumping. Air compressor--->>>http://en.wikipedia.org/wiki/Air_compressor
petrol station not, direct from atmosphere, ambient. again, my personal experience the pressure has dropped after 1 month usage & no pumping. i did a comparison on both cases. Both cases, only drive to & fro office & home, some drivings at town.
above is just my personal experience, there are still many factors need to be considered in order to get a fair comparison.

why did your friend's tyres exploded? Were the tyres old?

new tyre, detailing of tyre usage/mileage used before exploded/his driving habits/etc don't have.
he overpumped his other brands (no info on what brands) tyre no problem.

ehm.. i m testing new pressure today.

on 195/55/15 F1 GSD3 (max is 51)

now on 39/39

quite bumpy

but steering seems lighter.. lets see my mileage got increase or not

if he had no problem on other brands...then it could be that tyre manufacturing fault?

steering is lighter because lack of grip. Same case with me. Yesterday went a bit too quick on a corner exit and the steering swing out so quickly, almost didn't catch back on time

let me drive awhile with tis pressure..

see can tahan or not..

I pump 32psi all round. BFGoodrich G-Force Sport 195/50/15

..
refer to door panel pse.
LOL

im now on 27psi (cold) on all wheels. i think i dun wanna use higher than 27 or 28 or even 29 psi cuz when driving the air gets hotter and the psi goes up higher thus, stiffer ride.

I think it all depends on the tire design. if the side wall is very stiff using lower psi gives u more comfort.

Eg. My Barum Bravuris sidewalls are much more stiffer than my Falken 522 sidewalls.

How much air pressure do i need to put for Vios original stock tyre?

175/70/r13..alwiz pump in 230kPa for all tyres..lazy to alwiz check..

Anyone notice that notice label kPa for spare tyre MYVI (near driver door) state that pressure is 420kpa? Isn't that too much for a thin tyre?

Front 32psi, back 31psi.

195/50/15.

front 230kpa, rear 220kpa

using 915/55/15

cool size u have man~
my stock car i put 34psi in front n rear 32psi~

anyone else?

stock ori tyre 185/55/15R ..front 33psi ,rear 31psi (read from analog gauge) not really accurate

if u pasang 'giant' subs at your rear boot. u may increase some psi at rear.due to the weight.

215/45/r17

35 psi front and back ...

215/60/16 - 36f/33r

tyre 185/65/15
F - 230 / R- 210

can anybody tell me why should get front tyre higher pressure than rear?

Either to compensate for the extra weight distribution (engine/gearbox infront) or to change handling characteristic.

im using 235/45/17, ad07, front 34 rear 33, how come my sidewalls always eats up faster than the middle, its has nothing to do with my alignment, cos have been sticking to the same tires 3 times. but i see some cars using ad07 is even. should i pump higher pressure?

Front: 225/40/18 (280kPa)
Rear: 255/35/18 (320kPa)

front 230...rear 220...205/45/17...

Potenza RE080
185/60/R15
F=260
R=250

I have a question. currently using ek3, with 195/60/r15
it is a bit oversized compared to original 185/65/r14
the recommanded pressure from sticker is 30/29 psi from the stock tires, and I been following that.

I found it is underinflated, and recently I push it up to 35/32 psi front back. but I still feel front tires are a bit underinflated.
the tire max PSI is 51 though.

Any sifu able to tell me how much pressure will be better?

hi there, i think need some help....
i accidently pump higher tyre pressure coz its quite dark at night to around 300 psi...any idea how to reduce the pressure?

195/50/15
Front: 260kpa
Rear: 280kpa

Then lost control,

Front: 200kpa
Rear: 220kpa

195/55/R15

Front - 210kPa
Rear - 200kPa

205/45/16 on MYVi 32 f / 30 rear.. okok only

195/60/R15

Recommended : Front ( 210 ) Rear ( 190 )
Max : 350kPa ( 51psi )
kPA Pumped : Front ( 230 ) Rear ( 210 )

Feels much smoother and lighter yet steady.

Might trying out 240 and 220 next time.

yo ppl! I'm driving persona with 205/55/R16 profile tyres;
whats the BEST Tyre pressure?
advance thanks to any comments.

Just press in the air valve with your fingernail.
