Nitrogen in Tyres
« on: 25 March 2010, 13:33 »
I filled my tyres with Nitrogen today. I noticed that the ride and handling of my GTi had improved slightly due to a slightly lower unsprung weight. The tyre presures before the change were checked and were correct.

I went to my local Kwik Fit who charged £1 per tyre. I felt it was worth it.

I am sure most forum members are aware of the advantages of using nitrogen to inflate tyres 

Here is a link from the AA:

Any one tried this?

I had mine filled by the dealer a couple of years ago on a TT and tbh could not tell the difference, I had the car for 7 months and what I do remember is that the pressures had stayed the same from new. I believe that quite a few dealers are supplying new cars with nitrogen filled tyres as standard.

I'm going to give this a try at the weekend, I think!

Maybe sort out the ride a bit more.

The GTD is like a blow up doll. The GTI is like a proper woman. Sure the doll might last longer, and the woman might have higher running costs, but which would you rather have?

Explain how using nitrogen affects unsprung weight.

Less density than air so for the same tyre pressure less nitrogen is needed.
If I remember my Chemistry 'O' Level correctly, this is explained by Boyle's Law.

What if you have a slow puncture and need to top the tyre up to get you to a garage?  (taking the spare wheel out of the equation)

I've heard mixed things from nitrogen tyres, I think its all a bit of a placebo effect.

I must have mis-read this bit then

 future top-ups would also have to be with nitrogen if any advantages are to be maintained
