Nitrogen in Tyres

[am1w]

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 was waiting for this!
Less likely with nitrogen to have a flat unless you are a Sadu and live on a bed of nails!
Top it up with air, go to the garage, get the tyre fixed, put nitrogen in it if thay have this facility, if not use air, go to 'your' garage next when you have time to deflate air and re-Nirogen, or deflate all tyres and fill them with air.
What a palava! Love it!

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

its £1 per tyre whats the worst that could happen  



I have used it a few times - not noticed any real performance gains but certainly seems to hold pressure for longer

Nitrogen ?   while its not flammable, I wouldnt want a blow out

Nothing like keeping the pressure up!

I noticed that the ride and handling of my GTi had improved slightly due to a slightly lower unsprung weight.

That is hilarious!  

I think this belongs in the mk6 nonsense thread.

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.

This is a piss-take, surely?

Air is 78% Nitrogen anyway...and last time I looked the molecular weights of the other 22% (oxygen, CO2 and other trace gasses) wasn't on par with deplated Uranium.
What a joke...

Try filling them with Helium...maybe your car will float, Back To The Future stylee.

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

A fool and their money?

I notice costco are offering this when fitting new tyres..

Explain how using nitrogen affects unsprung weight.Please

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.

Well, I decided to do a rough calculation to find the weight of air in your tyre at 40psi and I reckon it's no more than 150 grams. As mentioned air is 78% nitrogen anyway and the heaviest component you've excluded by using pure nitrogen is water vapour. Even at 100% relative humidity you've only got about 4 grams of water vapour in the air in your tyre. I reckon a GTI wheel and tyre weigh about 18kgs and you've lowered the mass of each corner by 4 grams max.

I think the benefits of nitrogen-filled tyres lie somewhere else. As in stability over a wider temperature range (thanks again to the exclusion of moisture), lower potential for corrosion and possibly slower leakage rates. Though unless you're lapping faster than Jensen Button on speed or are tailgating a space shuttle on it's way back to earth I doubt you'll notice any advantage.

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

Clearly the OP needs one of these
