20Tires Filled With Nitrogen Instead Of Compressed Air
This is why F1, Nascar, and Indycar racing all spend a lot of money on developing super-lightweight components from which to construct their vehicles.
The tires on regular cars are filled with compressed air, but that’s just a little too normal for race cars. Weight is hugely important when it comes to gaining even just a few hundredths of a second advantage over your competitors.
Motorsports teams also use nitrogen to fill their cars'
tires instead of boring old compressed air, as nitrogen alone is much lighter than the combination of nitrogen, oxygen, carbon monoxide and other gases which make up the air in normal tires.
