Check the tire mounting and air pressure. Inspect the tires every two hours or every 100 miles when driving in very hot weather.
Air pressure increases with temperature.
Do not let air out or the pressure will be too low when the tires cool off. If a tire is too hot to touch, remain stopped until the tire cools off. Otherwise the tire may blow out or catch fire. The engine oil helps keep the engine cool, as well as lubricating it. Make sure there is enough engine oil.
