The car

[CharlesHarris]

When I was in public works we had a substantial vehicle fleet which included 56 over the road lorries with 100-cubic yard walking floor trailers for hauling municipal solid waste to our waste-to-energy facility, which produced 80MW daily and processed about a millions tons of MSW annually. We also had 200 pickup trucks, 50 SUVs, and 100 other pieces of mechanized equipment. They did not use ambient air to inflate he tyres. They used only CO2, because ig a tyre overheated and caught fire the CO2 would quench the fire.
