After reading this article another question arsises. Focusing on the following line:
" Nitrogen will run cooler than normal compressed air"
The reason why we have warm up laps in F1 races is that it is a proven fact that the temperature of the tyre for racing cars is raised for better grip on the road. If the tyres run on Nitrogen which would cool the tyre quickly, it would thus decrease the grip of the tyre. As temp is directly proportional to the grip of the tyre.
This brings us to an irony that if the usage of nitrogen would actually benefit with respect to the grip of the tyre.
For an expaination to this irony, I could think of the following reason :
The racing cars move around so fast that the temperature of their tyres would increase temendously, thus it would help to use nitrogen and eventually get to the ideal temp for the best grip. Agreed.
But this is not the case for the city cars, in my opinion we would prefer the temperature of the tyre to increase as we would have better grip when tyres are warm. Also our tyres are not going to get so warm that we would require nitrogen. Thus we can come to a conclusion that using nitrogen in city cars would actually decease the grip a tyre would provide.
What do you think ppl?
I hope I am able to put forward my opinion in understandable language.
I agree that the F1 race car tyres are filled with Nitrogen, but still I couldn't relate to the answer that you gave. Maybe I was not able put forward my thought clearly, I will give it another shot and this time I will use bullet points of my understanding. I will be happy to know where I have misunderstood any concept, please correct me.
- Nitrogen Filled tyres decrease the opreating temperature of the tyres, and increases their life. Using nitrogen lowers the temperature of the tyre.
- A dry-weather racing tyre in Formula One generally operates at an optimal temperature of around 100° C. Thats why they have warm up laps. Also they use tyre heaters. All this to increase the grip which the tyre provides at the optimal temperatures.
- Now using nitrogen decreases the temperature, thus it would lower the tyre grip as well.
- Irony being: Why do they use nitrogen to cool it down when the have warmup laps and heaters to increase temperatures?
- A MAY BE explaination to the irony: What I could personally think of: The F1 cars move so fast that they increase the tyre temperatures tremendously, thus ruining the tyre perfirmance and creating an imbalance between the grip and wearing out of the tyre (due to the heat). So they must require nitrogen. (am i correct in saying this?)
- Now leave the F1 world, come to ours: We donot have warmup laps, nor tyre heaters, nor do we move around very fast during our city drive. Thus our tyre temperatures SHOULD not increase so tremendously.
- If we use nitrogen to fill our tyres, it would help decrease the temperature which is already not very high.
- As a result of which we would get lower grip.
Now my point is if Nitrogen eventually leads to lower tyre grip, why should we use it?
Yesterday I have filled tyres of my car with Nitrogen for the sake of having a first-hand experience. I went for a small drive on highway (total 40/45 kms) & have driven it in city conditions a little (10 kms).
I will be undertaking a 4-day trip of 1500kms during the month-end. I will thereafter post my experience here in regard to my observations & difference/s felt, if any, on road-grip/handling/braking etc.
Yes, I understand. I’m passionate but not over-passionate (at least wouldn’t like to be called so ).
And even if I’m, be rest assured… I’m very impartial & unbiased and so will my observations/findings be.
By the way, any suggestions on other things (safe of course) that I could possibly try for the sake of acquiring first-hand experience?
