The aim was to measure the heat release rate when a large vehicle tyre burns. A maximum heat release rate of no less than 3 MW after 90 minutes was recorded. This information will help to assess the process of fire evolution in different types of construction machinery. It is of particular interest in connection with underground fires. It was found that a design value of 0.2 MW/m2 is a good value to employ when one needs to estimate the maximum heat release rate of a large tyre. This value was found to be reasonable when the exposed fuel surface area was definable. It was also found that 86 % of the total heat energy was released 2.5 h after ignition.The report describes a fire test with a front wheel loader rubber tyre under a large laboratory calorimeter.
