No matter whether it is a heart over head "Aspire" or sensible "DZire", an enthusiastic driver will always enjoy the car according to it's merit.
One of the major factors of spoiling a driving enjoyment are the settings. Starting with the condition of the car and it's major components. According to the "amm junta", forum members are over-maintaining their cars. But we know, it's not only about running the engine, it's more about that feel of it. So we may change the Oil / Filters earlier, use expensive oil for their feel. Buying that expensive imported tyre and so on. Even the mundane stuff that many doesn't pay much attention too, we spend hours to find that perfect seating position or that ORVM adjustment point.
Tyre pressure is no different.
Sure, in shorter city drives, we are occupied with the traffic, trying to save the car from scratches and paying less attention towards this but out in open highways and 15/16 hours long drive, if the pressure isn't right, it screws up that perfect driving feel.
Aspire (and many others) have some wired Tyre Pressure recommendation.
1 Driver -> 32 psi
2 people some luggage -> 33
and so on till fully loaded meaning 35.
I always wondered, they should have given a tyre inflator along with the spare wheel. According to the manufacturer, if I am going to office alone, I should be driving at 32 and in case I decide to go partying with Office Folks, I am suppose to increase the pressure to 35? and reduce that back to 32 when coming home?
But in practice, car runs just fine with pressure being any where between 30-35. That's not the issue, rather the driving feel between 30 vs 35psi is. Ride quality is noticeably softer and comfortable with 30 where as the acceleration feels little dull. Increase that to 35, its now other way around.
It's somewhat true for most of the cars. Regular driver would immediately notice if his tyres are over or under inflated to his liking.
So what we do? We settle for something in between as per our liking. For me, in case of my Aspire, it's 33.
Problem with air pressure comes in these longer hot weather and hill climbing drives. Usually I would be tanking up a night before the departure or may be at early morning. Ambient temps are like 28c and my usual CoCo Pump is within a km of my home. Starting the drive, I am satisficed with my settings but many hours into the drive, out side temps are touching 44/45c. Road surface is super hot and I am driving aggressively. Result? Tyre pressure shooting up by 4/5psi easily. Messes up that perfect setting. Subtle but sufficient enough to cause constant mental irritation.
This difference is more evident when you push it up the hills. Tyre Pressure touches like 40psi and beyond.
There is a say between the old timers. If your tyre has no puncture and in good condition, pressure inside will increase. Very true as with Normal Air, every time I go for pressure checking, I would see the machines reducing the pressure by few psi
Why Nitrogen and Why not earlier?
Nitrogen isn't a new concept in India. But availability is. Earlier, in case of a puncture, unless you are in some big city, you would end up with 1 normal air and 3 on nitrogen. However, at present, those branded tyre shops are everywhere and most of them have nitrogen. In fact most of the CoCo Pumps are now offering FREE Nitrogen fill ups.
So availability concern is no longer a challenge.
However, there is still another factor which held me back from switching. This 5th gear video ->
Contradictory to the claims of the companies pushing Nitrogen, this auto show testing shows Zero benefit, on top the pressure increased more with N2.
Then why did I switch?
Purely out of coincident. During my
tyre fiasco (Ford Aspire : Official Review), that mechanic informed me about the N2 fill up after the work was completed. So I thought let's not waste & try it out for a while.
And? What is the result?
First thing I noticed within 7 days of city usage. When I went for pressure checking in a CoCo Pump offering N2, all 4 tyres are stable at 33psi. Gradually, I could see the lack of need to check the pressure since it's always staying stable at 33, no matter what time of the day or how warm the tyres are.
Neither it was the first time I drove the quoted route, nor Aspire was the only car in which I did this route. But it was the first time with Nitrogen.
If you are like me, able to notice the subtle differences and irritated by the settings change of your liking, then the lack of difference is night and day compared to Normal Air.
Tyre Pressure stayed same through out, that perfect driving feel was maintained even at higher altitude hilly terrain. Never felt the need to recheck the pressure.
Thanks.
