I do not have a full understanding of why truck tires blow out, but I think heat is a big part of it. So why not cool the tires as you drive? And do that without spraying water all over the road as you go by?
Tire pressure monitor systems already exist, as do flat-proof tire air systems. Why not put a temperature gauge inline and hang a tank of dry air or CO2 under the trailer with a radiator, so that when the tires get hot they can have fresh cool air exchanged internally, thus bringing down the temperature of the tire. I think the technology is already here, it’s just a matter of putting it in place and proving that it works. Cold air goes in one valve on one side, hot air comes out one valve on the other side, then gets cooled off by the radiator and goes back into the storage air tank.
