Pumping Tyres - some noob qns

[Yeobh]

Frankly I have being associate with the auto service industry for more than 3 decades and still in going strong, yet I have not come across a tyre gauge that come with a screw-on chuck. If your are referring to tyre inflator maybe yes - but mainly used by the cyclists and bicycle shops.

got some pics of my gauge

 

is that what u considered as screw-on chuck?

Uable to have a clear look at the chuck , even trying to enlarge the photo. Looks to me this is a stanadrd straight chuck used mainly for motorcycle and vehicles with tubless valve point 100% staright up. Simailar to the one as per photo

[Madsumm]

Where did u buy this?

For mutispoke rims, SUV wheels, double wheels etc you sholud use this gauge as photo with long chuck that can take straight and angular tubless valve

Check out ebay or yahoo auction spore

I can confirm that there is a tyre gauge that comes with a screw-in chuck coz I went Autobacs and bought one myself !

 

However, its not really suitable for me so I exchanged it for a straight chunk type and a hydrometer !

[Xefera]

Yoh bro, thanks for helping to prove my claims.

 

Yah, I agree that the screw in type is a bit troublesome to use. The straight chunk type is much easier to use. BTW, how much did you pay for that? Thinking of getting one myself too.

The one recommended by Genie47, Mustafa no longer selling

 

ya i went mustafa last friday cannot find liao...

 

So i got Amoi" brand from Autobaccs at $10+.. measuring in KPA only.. no hose but the head can be turned 360degree, construction quite solid. quite accurate also! come with a nice plastic case. There is another version with hose but it cost $30++!!

I see...

 

To me I'm not so crazy about the numbers cos to me that small amount is insignificant.

 

I did it at KM, so every servicing I'll just ask them to check.

 

Just yesterday I changed my set of tyres and then drive to KM to top-up(not far from workplace), I realise having pure nitro the ride is slightly more comfy and quiet.

 

I dunno, maybe it's just me.

 

Bro, new tyres that's why quite la.

Old tyres with vulcanized/harden rubber is noisy.... not to mention dangerous in the wet.

Your new sensation of comfy and quiet due to your new set of tyres... nothing to do with Nitrogen gas in the tyres.

Enjoy,

Cheers

 

bro, having nitro does not make yr tyre softer or more comfortable.. most likely last time at KM, they pump up yr tyre to 240kpa, then this time they pump 200-210kpa.. so yr tyre much sofer now so of course can absorb road noise better so are quiter and more comfy. my car tyre on normal air also works the same way..

Did you see any internal threads in the chuck? For me it is just very inconvience to check tyre pressure in this manner, unless the designer has other special application for this " screw-type chuck".

The closest is clip-on chuck widely used to inflate tyres especially in tyre shops or tyre factories

[Kklee]

Yes, there are internal threads in the chuck. I deliberated over the screw-in, straight and swivel chucks... bought the screw-in but found not really suitable. I had the swivel head chuck before so got myself the straight chuck which is, to me, the most suitable.

[Kklee]

I bought the "Autogauge 2" Face" costing around $10 and $15 for the hydrometer. Actually I can do without the hydrometer but I need to exceed $17, which is the price I paid for the screw-in gauge.

[Kklee]

The digital ones at Autobaccs looks tempting too yeah? I really must stay away from there!

[Xefera]

i c. thanks.

Sorry off-topic a bit... So is there any great advantages of pumping Nitrogen?

[Sg_specialist]

Nitrogen is more thicker than oxygen (as per the article). Oxyen escapes more quickly from the tire than nitrogen.

 

 

The main reason to do this is to avoid having moisture in your tires. If you fill your tires with warm, humid air, as the temperature goes down moisture could condense out. This can lead to some minor balance issues- especially if the water freezes, but it also makes it difficult to maintain a specific pressure. This is why airplanes use nitrogen. It is cold up there, and those tires need to be perfectly balanced and perfectly inflated when the plane lands. If moisture in the air freezes, this isn't going to happen.

 

You also don't have to worry about oxidation inside of your tires.

[Kklee]

If you are sensitive to tyres pressure loss and they lose pressure often, nitrogen is for you.

[Scaglietti]

Nitrogen is "thicker" than oxygen?... where did that come from?

 

If you are talking about density. Oxygen is denser than nitrogen. And nitrogen being lighter diffuses faster. Not the other way round.

 

What is that with water freezing and tyre imbalance???

 

There is no basis at all!
