Tyre Extinguishers

Tyre Extinguishers is an international climate direct action group which deflates the tyres on sport utility vehicles (SUVs). The group describes driving an SUV as "among the worst single actions that one can take in terms of its climate impacts and its adverse effects on public safety", with SUVs having a disproportionately large impact on the climate crisis relative to other vehicles, worsening air pollution and being more likely to kill pedestrians than smaller sedan cars. The group has called for a ban on SUVs in cities, and has said that they "want to make it impossible to own a huge polluting 4x4 in the world’s urban areas".

The group suggests inserting a piece of gravel, lentil or other small object to depress the pin on the valve cap of an SUV's tyre, so that the tyre deflates slowly over time. The activists leave leaflets under the vehicles' windscreen wipers "so that the owner is aware that the car is unusable and gets an explanation as to why this has been done."
