A Schrader valve has a lot of metal in it. Cutting them isn’t easy. A valve stem remover is cheap, about $6. Unscrew the valve stems and the tire’s air pressure will push them out. Throw the valve stems far from the car. Alternatively you could use a bodkin to puncture the sidewalls of the tire. A bodkin is a little tool used to make fishing flies. Think of a tiny ice-pick. A very small hole leaks slowly and doesn’t make much noise, making it easy to get away unnoticed. If you slash a tire with a big knife, the air comes out fast and makes a loud pop. If you don’t want to be noticed, don’t slash the tires with a knife unless the air is already gone.

For a moment I thought you wanted to suggest to go medieval on their
