      Hi Friends

      COO IOC bunk at BTM main road is offering free Nitrogen fill for fuel bill above Rs. 750 for 4 wheels and Rs. 300 for 2 wheels.

      I got all five tyres filled with Nitrogen yesterday. There was a change in handling and vehicle floats and glides. I found a plush feel and sway in the vehicle on uneven roads. Small holes and potholes have no effect and the car glides over them. Maybe because the car was not loaded.

      Afterwards it was loaded fully and the car was stable.

      Nevetheless there was difference which I felt immediately. Unable to explain them properly, so fill it and enjoy the ride.

      Its an automated kiosk, where the normal air is sucked out (vacuumed ) and then Nitrogen filled. So you need patience and it takes atleast 10-15 mins, unlike the normal air fill. Not many people take the offer. So kiosk is empty.

      Utilize this opportunity and enjoy the ride and difference. The offer is expiring and avialable for a day or more. Hurry.

      Good test Digital Vamp, and it will be an eye opener for people who fill nitrogen in normal road cars. After all atmosphere air is 78% nitrogen, so filling pure nitrogen is just another 22% more nitrogen compared to normal air.

      The shift in momentum while braking puts more weight on the front tires. Hence the braking forces on them are greater than the rear. And the cooling part being the wind in the front, as you mentioned.

      Hi DV

      Thanks for the accurate measurements.

      Can you provide your inputs on the difference in ride quality, over highways, normal city roads, over potholes and over speed breakers? I did find a difference for the better in ride quality.

      Your input on drive quality would be appreiciated.

      Ride Quality is perceived differently by different people and I guess it is very difficult to arrive at a conclusion whether it has improved/stayed the same/worsened.

      In my personal experience, ride quality has not changed but some times I feel it has become more harsher over the speed bumps...Could be just a perception!!!

      I'm really sorry that I missed to capture the readings immediately after those high speed runs.
      After I reached Mysore, I totally forgot to capture it and the next day at Ooty, my windows tablet ran out of charge and then only I realized that I forgot the charger.
      I understand that the above results don't add much information than we already know but I thought I'll post them anyways.
      There are some longer trips coming up and I'll ensure that the post-drive results are captured well.

      Thanks.

      Does the ride quality perceived differ due to the make of car and type of its suspension, the miles on the ODO etc...?

      Let me ask a question to experts here. Hyundai recommends 30 PSI for all tires when car is not loaded, and 33 PSI when the car is fully loaded. In this case, is it advisable to fill Nitrogen?

      Just fill normal air. The above test done by digital Vamp proves that filling nitrogen in normal road cars is not helping in anyways.
      Also please understand that atmosphere air is 78% nitrogen.
      33PSI when loaded is to avoid excessive sidewall flex under load, also it is recommended to use slightly higher PSI on NH drives as again during high speeds this will reduce sidewall flexing.

      Attached few links here, please have a look.
