Is this weird or what?
« on: August 09, 2008, 06:42:05 PM »
Hi all,

Do you guys notice the air pressure in the drivers side tyre tend to drop faster then the other 3 tyres?

Everytime I refill the air in my tyres, I noticed the tyre pressure on the drivers side have drop down to 205 while the other 3 only drop to 245 (i always set it to 250)

how often do you refill the air in your tyres?
how many times have you observed this situation?

seems to be more a possibility of a leak than anything else
Be safe. Go with the flo.

Hi moochi.There is nothing wrong with ur tire n y the pressure on the driver side will go down faster is bcos our engine bay weight heavier on the right accordingly to the tcm svc advisor.Another reason is most of the time we r driving by ourself which add on weight to the right n therefore will cause tis to happen(correct mi if i m wrong)Hope the information will helps... ;D

Most likely that particular tyre valve needs to be replaced. Costs $5 at most.

I second that. Quite unusual to have 3 tires lose 5 kpa and 1 losing 40. Very likely to be small puncture or leaky valve if the tires are new.

250 for rear is very high. Do you carry passengers behind very often or carry alot of load?

No i don't carry passanger, mostly it's just me. Initially I used to refill 230 for front and 210 for rear, then i came across some members here who refill 250 for all 4 wheels so i'm trying that out. It feels less bumpy so I've been sticking with it.

Btw, my ride is a 2005 latio sports and I've been running on the stock tires to date. Thinking of switching soon but still considering the brand and price. I don't want to switch my rims so what can I go for. Roughly cost $80 per tire.

I have to refill every 10 days or 2 weeks as I can feel the ride is not smooth enough.

I was thinking that too... care to montior your tires pressure next time you refill so I can compare if the drop is similar?

hmm for my own, i do get even air loss for all the tyres.

Try pumping Nitrogen gas in your tyres and the tyre air leakage will be very minimal, if any at all.

It also reduces fuel consumption as nitrogen is lighter than air and does not heat up so easily. Your tyres will not be so hot after running too.

Costs $5 per tyre.

hi!

actually nitrogen to me really nothing special leh. many ppl said minimum gas leakage but hor it always become lower after awhile. altho i can get free nitrogen top up till the end of life for my tyre but i really dun bother liao lor. 1st, to top up i need to travel fr my hse to ubi.....wah far leh. 2nd, petrol kiosk is everywhere. pump air is so convenient. except sometime those I D I O T ppl who always park at the area but not pumpng air and disappear.

just my personal view  ;)

Hahaha... met one on saturday at shell hougang. This bugger park the car there and left to buy newspaper, I got to wait for him to stroll back to his car before i can refill air...  :glare:

How do i check if there's a leak? Bring to mechanic?

Just bring it to any tyre shop to check.

They will put your whole tyre in a big tub of water to check for any air bubbles.

If there is nothing wrong, and no leak in your tyres, ask them to change your tyre valve.

It should not cost you more than $5.

Hi,

May I check with you guys what's the advantage of pumping nitrogen? Where in Ubi can pump nitrogen?

Less heat built up which results in better mileage, and less frequent air top ups.

Most tyre shops offer this service.

Try the Paya Ubi stretch.

Thanks clarence. Why would nitrogen lead to less heat built up?

How much it costs for the air topup?

Nitrogen is less dense.

$5 per tyre for Nitrogen gas top up.

Hi, see below.  hope it helps
cheers

Inflating tyres with Nitrogen is a technology that has been applied in aviation and car racing for the longest time. Due to its many advantages, this technology is now adapted in passenger car Tyres too! At the forefront of car servicing technology, H TYRE gives you access to these touted benefits with our nitrogen inflation machine.

As the rubber used in the inner linings of tyres are not completely impermeable, pressure loss can be expected overtime. This often necessitates regular tyre pressure checks by car owners. Because of the molecular structure of Nitrogen molecules, they diffuse slower than the oxygen in compressed air through rubber linings. With nitrogen in your tyres, you could expect tyre pressure to remain unchanged for periods up to half a year. This brings about greater convenience to car owners with fewer visits to the air pump.

If you have your tyres inflated with Nitrogen at H TYRE, our guarantee to you is that the Nitrogen will last for 6 months. Should the unlikely event that your tyres lose pressure within the period of six months occur, we will give you a free top-up!

Another advantage of having nitrogen-inflated tyres is that of having a cooler running tyre temperature which correlates to longer tread life. At the same time, tyre failure due to excessive heat build-up through high-speed long distance drives (i.e. car owners who frequent Malaysia for long drives) can be extremely dangerous. Why put you and your passengers at such unnecessary risk when having nitrogen-inflated tyres greatly reduce the possibility of such an event occurring.

Furthermore, nitrogen molecules are lighter than the oxygen molecules in the compressed air which is the reason why your wheels feel lighter with nitrogen. Greater fuel economy can be expected which amounts to huge savings for companies which have big logistical fleets especially to taxis. At the same time, owners will also experience tangible improvements in acceleration from rest owing to lighter wheels.

Rusting is a problem that annoys many car owners. Rusting of the inside of rims due to the constant exposure to the diffusing oxygen from within the tyres, rusting of the wire linings within the tyre structure are all common examples. Rusting is oxidising caused by the presence of oxygen and moisture. With tyres inflated in dry nitrogen, you can avoid the woes of rim corrosion as well as compromised tyre structure integrity due to rusting altogether.

On top of that, the presence of oxygen in the compressed air results in oxidation (hardening) of rubber from within. For longer-lasting tyres, do inflate your tyres with nitrogen rather than compressed air.

With benefits such as less frequent visits to the air pump, longer lasting tyres, greater fuel economy, faster acceleration from rest, less rim corrosion and oxidation of rubber linings. What are you waiting for? Come down to have your wheels inflated in Nitrogen!

Our nitrogen inflation machine has a special membrane that is able to filter out the natural occurring nitrogen in air to give you pure dry nitrogen for inflation purposes. From this method, we are able to extract nitrogen at a low-cost, thus passing these savings on to car owners. Thus the service will only cost SGD$5 per wheel.

Caution: For owners using nitrogen in their wheels; your wheels have been vacuumed of any air before being inflated with nitrogen, do not top up with ordinary compressed air as this will negate the advantages of nitrogen inflation and upset the true tyre pressure.

Customers who have purchased tyres or rims will have enjoy first FREE NITROGEN-INFLATED WHEELS!
