Environmental campaigners, Tire Extinguishers Edinburgh, claim they deflated 50 SUVs overnight in the Merchiston and Marchmont areas of the capital.
In what Guerrilla Eco Group says is the biggest night of action to date, Tire Extinguishers also targeted SUVs in major cities across Europe.
Since March, more than 200 SUVs have been dumped in the Leith, Portobello, Hillside, Marchmont, Bruntsfield and New Town areas.
Last night’s action marked six months since the start of the tire extinguisher movement in the UK – but the group has warned their “movement is just beginning”.
Tire extinguishers want to make owning an SUV “impossible”. She describes them as a “climate catastrophe”, “dangerous” and “unnecessary”.
Members of the group deflate tires by pushing small objects like lentils into their valves. They also leave leaflets on the cars they target, stating, “We are doing this because driving your massive vehicle in urban areas has tremendous consequences for others.”
The group has called for the government to introduce “bans on SUVs in urban areas, environmental levies to tax SUVs, and massive investment in free, comprehensive public transport.”
However, they say: “Until the politicians make this a reality, the tire extinguisher action will continue.”
SUVs have elements of standard cars, but are larger and have off-road capabilities like high ground clearance.
