iv done this before when im in perth, espicallay at trigg/scarbs for a swim.
There was a ford xr6 - sped in, pulled up parked in the disabled carpark and went for a surf. luckily i had saw this, made sure he had no sticker after he got out his surfboard. Had my arb EZ deflator which takes the valve out to deflate the tyre in seconds.
for some reason 3 mins later he had 4 flat tryes.... and zinc on his windscreen forming something along the lines of having a male anatomy on his head.
