Nitrogen in Tyres

[am1w]

Do you think that someone who has never washed or hovered a car would inflate his tyres with Nitrogen?

I thought id make my input on this matter, as im a motorsport technician i know the advantages of filling tyres with nitrogen, it may not be as noticable as on the road, but you will notice it majorly if on the track as filling them with pure nitrogen keeps them at a constant temperature and prevents the tyre temperature from changing.

Other way round - the tyre heats the air inside. The advantage of using nitrogen over good old air is that the pressure changes less with increasing tyre temperature because there's no water vapour in there. As you say, on track this will make a significant difference.

On a road car most of the time it matters much less. Checking your tyre pressures weekly is far more beneficial than using nitrogen over air.

Also. The tyre would need to be completely empty of air to start with.

i was hoping someone would do the maths. imagine being able to feel your car being 4 grams lighter per corner - getting in your car with a spec of dirt on your shoe must right upset the handling 

Imagine the difference it would make if you hadn't been for a sh!t all day....

I best keep away from maccy's

Nevermind the nitrogen bullsh!t... why on earth are you doing letting kwik fit monkeys anywhere near your car?

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?

The part about the unsprung weight is pure nonsense, the difference in density between air and nitrogen is approximately 40grammes/m³. I haven't worked out the volume of gas in 4 tyres but would guess at around 0.05m³. This means you would reduce your unsprung weight by 2 grammes! Are you saying you can notice this? I don't think so. The only advantage is possibly the reduced moisture content meaning more stable pressure.
