Title: Pump Tyres Air
Post by: iagree on December 10, 2008, 11:12:57 AM
Hi guys,

I have no time to go to HengTyre @ Kallang there to pump my Nitrogen air for my new GR80 tyres...

Last night, I pump at ESSO fuel stn @ clementi. Those air are not Nitrogen air right?

The front tyres, i pumped 230. The rear tyres, i pumped 210. Follow the common standard, dare not over pump the air pressure. Any comment?

So, now the air in the 4 new GR80 tyres are mixed liao, how ah? Any knowledge need to share with me for this issue?

Thanks in advance.

Yours iagree.

Hi all

Any fuel stns provide Nitrogen for our tyres? If there is any, then I can pump from there liao, i don't have time to travel to HengTyre to pump, not convenient... Regret liao to chg my tyres at HTyre coz I dont have time to go there...

IMO, to chg tyres, choose a workshop which is the most convenient to you, for e.g. i shld chg at the West side of Spore. Most convenient to me....

Last night, my tyre pressures (Before Pump) were:
1) Front tyres, around 205 before pump
2) Rear tyres, around 195 before pump
I guess it is normal? I hv never done any air pump for 5000km after my last changed of my 4 GR80 tyres.

Regards.

only free AIR (no nitrogen) provided at petrol stations

Do you measure your tyre pressures using your own tyre gauge?

Front 205 and Rear 195 - the tyres are underinflated.
How's your FC lately?

All petrol station provide ~78% Nitrogen FOC because the air that we breath in contain that much of nitrogen naturally.

you are right, I meant not 100% nitrogen

hi Silver

FC? if no stuck at causeway (jam) , the FC is abt 13kmL. if stuck, most of the time is abt 10km/L.

front 205 n rear 195, abt 2 to 3mths never pump already.

where is own tyre gauge? how to check?

if normal AIR vs nitrogen, now both is mixed in my tyres, any impact?

thanks.

hi ying

i see.
HTyre told me, i can pump at any petrol stn first, then go to their workshop to repump all Nitrogen air to the tyres leh.

but, mix both type of airs in tyres is ok rite? if no bad impact, then leave it.

regards.

does it mean that you don't have your own tyre gauge?
then how do you know that the pressures are 205 (F) and 195 (R)?
by reading from the pump?


any impact of air and "pure" nitrogen mixed in the tyres, - so sorry, I have no experience with that
maybe just that you will not be able to enjoy the full benefits of "pure" nitrogen - lower heat generation, slower tyre pressure loss, etc

perhaps u can try spending less time playing forum & msn, then you will have more time to go H Tyre and fill Nitrogen liao lor!

Forget abt N2 just pump normal air at the kisok will be suffcient. And further more pumping N2 for daily usuage no difference and both also need to top up around 2 weeks. Always pump when the tyres are cold less than 200km of travel.

Hi

You can mix nitrogen with oxygen.  Been doing that for the past 30k.  Normally at each 10k service interval, autosaver will deflate
all 4 tyres and pump with nitrogen again.

thanks for info.

ya, i read from the pump, the moment when i pump, i see it starts from what # loh.

hi Carmodz

i dun quite agree with this leh.
forum? i seldom come in. after i close the web browser then i will forget to login liao UNTIL i have questions to ask them i will come in mah.

HTyre too far, not convenient, and dun forget, purposely travel to HTyre before 8pm i got to pay ERP @ the Central shopping mall (towards Bugis). Worth meh? S$1 - S$2 for the nitrogen oh?

ic. gd info. thanks for sharing. then i dun hv to go to HengTyre liao.

every 2weeks need to chk n topup air meh?

hi robtan

so good ah? autosaver deflate for us and repump?

haiz. frankly spking, i thk i will go back to TCM for my subsequent servicing liao. coz i thk go back to TCM, no doubt is to spend abit more, but at least we feel more comfortable mah.

and dun forget, TCM@BktTimah there have launge and free drinks leh. and sometimes got sexy pretty SE walk pass? ^$^

Post by: Ying on December 11, 2008, 10:47:25 AM
haha, it is more choice and fun to service outside but less worries with TCM service package.

you will never get 100% pure Nitrogen gas in your tire, since there is always some air in the tyre. Unless they change the trye and pump Nitogen gas in outher space for you.

hi ying kor

ic. tcm svc pkg, i thk few 10dollars more . still can tahan. hassle free. but the oni prob is we must BOOK earlier else Saturday time slot is always full ... must book 2wks in advance.

good idea. so dun care liao lah abt the N2. i just pump at normal petrol stn lah.
Title: Re: Pump Tyres Air
Post by: robtan99 on December 11, 2008, 04:21:56 PM

Do take note if you decide to go back TCM, then u can totally forget about nitrogen and this question should not worry you any more.

Coz TCM only have air like any other petrol stations  :bleh:

Yes, best is to check every fortnightly. I tried and even when on N2 was told to come back to stamford to top up. Then when I tried normal air, it was the same frequency and best of all the kiosk is so much nearer to stamford. And do note not all of them wait for the tyres to cool before topping up thus the tyres would always be under inflate.
Title: Re: Pump Tyres Air
Post by: Silver on December 11, 2008, 10:40:46 PM
actually less than 1.6km
(see manual page 8-30)

Ya. 1.6km how to ? Unless the petrol kiosk is next door of your block. Think most of us pump while it is hot tyres. Then how to compensate ?

Eg less than 1.6km - pump 210 and 230
1.6 km - 10 km - pump ???
10 km - 20 km - pump ???

hi vortex

iagree w u.
sigh.

may be 15km drive, then when arrive there, wait for 15min before start pumping? ^$^
Title: Re: Pump Tyres Air

Tyres are considered COLD after the vehicle has been parked for 3 or more hours (see same page of owner's manual)

Usually, you can compensate by about 10 to 15 kPa extra when pumping "HOT" tyres

Do invest in a quality tyre pressure gauge and you can check the tyre pressures COLD before you drive to the kiosk and check the tyres when they are HOT and then you can see how much to compensate

on a side note, good read :

Hi iagree, noticed that the tyre pressure at 270/250 not really that scarely after all (though abit bumpy). I'm on this tyre pressure now after poisoned by some of the bros here. Will monitor the FC + some skills shared by bro fri13th, liewks, toalson,etc.. :thumbsup:

Recommended tyre prssure for COLD tyres is 200KPa, so for a warmed up tyre, an extra 20KPa in pressure to compensate means one should pump 220KPa.

But in the name of fuel efficiency, I think many forumers are pumping way above the recommended pressure, up to 280KPa.

Speed kills more than tyre pressure, sign board on the road "110km/h", how many people follow leh? you always follow?
Title: Re: Pump Tyres Air
Post by: Silver on December 14, 2008, 02:00:44 PM
driver errors, mechanical failure do
speed (per se) don't kill

even those who were at 0 kph parked by the road shoulder died when vehicles plough into them
Title: Re: Pump Tyres Air
Post by: Ying on December 14, 2008, 02:29:10 PM
like what you said, another car hit a 0 kph car, chances to survive is better if the car was travelling at 30 km/h than 110km/h right? Sure, speeding can consider as driver errors or should i say failure to control the car over speed limit? you can play with words but fact is fact.  :glare: speed don't kill? god bless ;)
Title: Re: Pump Tyres Air
Post by: Silver on December 14, 2008, 03:02:18 PM
failure to control car even at speeds below the speed limit can also result in dire consequences

nice simple slogan to have : speed kills

but the truth of the matter is that it is not as simple as that
