Idea
The idea is to make checking tyre pressure mandatory when a vehicle is refueled. A pressure gauge can be a part of each fueling machine. While the fuel is being filled, the worker can check the tyre pressure.
Details
The idea focuses on a vehicle's tyre pressure to control emissions, save fuel and help the ecosystem. If we suppose there are 30L vehicles (four-wheelers) in Delhi alone and out which 10% runs on under-inflated tyres then the following calculations will show us how much we can benefit by implementing this small idea:
I have taken the worst case scenarios and not included the two wheelers and other vehicle count. The actual numbers will be much higher (Total Vehicles, Under-Inflated Vehicles, Mileage effected)
Assumptions
- Total Number of Four-Wheelers: 30L
- Vehicles running on under-inflated tyres (10%) = 3L
- Mileage effected (3%) i.e. for a vehicle with 15Km/Litre, under-inflation will bring it to 14.5Km/Litre
- On an average, a car is driven 500 Kms per month and gives a 12Km/Litre of mileage with correct tyre pressure
With Correct Type Pressure
Fuel used by each car per month = 500/12 = 41.66 Litres
Fuel used by 3L cars per month = 3,00,000 x 41.66 = 1,24,98,000 Litres
With Under-Inflated TyresReduction in mileage = 3% = 11.64 Kms/Litre
Fuel used by each car per month = 500/11.64 = 42.95 Litres
Fuel used by 3L cars per month = 3,00,000 x 42.95 = 1,28,85,000 Litres
(1,28,85,000 - 1,24,98,000) = 387000 Litres x 50 (price of fuel) = Rs. 1,93,50,000
i.e. Rs. 2 crore worth of fuel can be saved every month in Delhi with the above figures
If we take the all india figure of approximately 10 crore vehicles, the fuel saved per month will go upto
(4166000000 - 4295000000) = 129000000 x 50 = Rs. 645,00,00,000 i.e. 645 crore rupees/month => 7740 thousand crore per year

Other Benefits
- Less wear and tear of tyres. So the tyres will be discarded less frequently and we will have less rubber to dispose
- Emission levels will be reduced as less fuel will be burnt
- Better handling and control of vehicles will reduce accidents
