Nitrogen filled tyres are the answer to the problem of tyres overheating in the North Queensland summer heat.
Nitrogen filled tyres run cooler, get better mileage, have less loss of pressure. Pressure I the tyres varies less between hot and cold, meaning the tyre behaves the same for the whole trip.
This is something North Queensland truck and low loader owners have known for years. It is now available for private vehicles, through John Muller Tyres.
