[Auto Talk] What tyres or tires are you using?

[Chai]

Nitrogen for Tyres - Fact Sheets - Motoring - RACQ

hmm, thats means it does not really work eh...who cares ..Not my car XD..since i'm not driving it yet

[Chai]

Yeah it's a waste of money. You should always check the tyre pressure regularly, twice a month is good. I rather spend the money on a good tyre pressure guage to make sure it's at the right pressure.

I am using hankook from korea. Forgot what series but cheaper

Adrian, the other thing to look for is fuel consumption. Low profile tires or wider tires might not be so fuel efficient. The hankook shop in Sunway give trade in for old tires like rm40/piece if not mistaken which reduce your new tires cost . The shop does has other tires brand also if you not too fond of korean tires.. ooh wait you drive a korean car .. hehehe

Lower profile tyres will not affect fuel efficiency. Wider tyres yes, due to larger contact patch area, but honestly it will be negligible. I personally think that the weight of the tyre will affect fuel efficiency more. Yes, different tyres at the same size weight differently. You most likely need to change the rim to support wider tyres as well.

Korean tyres are not really good IMO.

Lacus: They are not using pure nitrogen, so it won't make much difference, other than clearing your pocket. I stick to good old air.

It's not about believing or not. Hehe.. I just think that if proper QC is adhered to, there should not be any difference in the quality of the product, whether it was made in Japan or elsewhere.

One thing though, tyres are not delicate instruments that require tight tolerances and fine finishes (like high-end cameras require). Unless Japanese factories have special manufacturing technologies that cannot be exported overseas, I really wonder if there's a significant difference in quality.

Of course, their overseas operations can always goof off. Haha.. But that speaks of poor corporate governance and culture.

AFAIK, the advantage of using nitrogen is that it doesn't contain any moisture, so tyre expansion will be more even.

Some shops claim that it will help mileage because it's lighter, but I don't think the few grams will help much. Besides, normal air is about 78% nitrogen.

As for heating up the tyres, I'm not sure... but I don't see how nitrogen can reduce the heat of the tyres. After all, the tyres are heating up from contact with the road. The nitrogen is on the OTHER side of the tyre...

If I'm not mistaken, the pressure of the tyres can help improve mileage as well.

Higher pressure = firmer tyres = better mileage.

But of course, we should keep it within normal limits!

Yes and No. Lower profile tyres decrease the diameter of the tyre using larger rims help. If you use a low profile tyre then a standard size on say a 16 inch rim you will loose gas mileage and it will also affect the calibration of your speedometer.

True !!

I keep mine around 28PSI in the summer and 26psi in the winter. Higher is better for mileage but if you ever get stuck in snow and are alone .. let some air out .. tyres have better traction with lower PSI
