I posted a question about what tire pressure should be recently but I was wondering if I lower my tire pressure does that make the tires wear sooner?
Will lower tire pressure cause my tires to wear faster?

Proper pressure should increase their life. The goal is to find that proper pressure for the weight and tires on your vehicle.
Running the incorrect tire pressure can increase tire wear. Lowering the air pressure will increase tire life if it was overinflated.
This is why we tend to give a range (24-29 psi) when asked about it. Every vehicle and tire combination can be different. Add in wheel dimensions and it is nearly impossible for someone other than the driver to determine the exact pressure they need.
I did a chalk test (there are some good youtube videos on this) and found that 26psi was spot on for my lj
Overinflated will wear the center of the tire faster, underinflated will wear the edges faster. But we're talking about psi that is significantly higher/lower than ideal.
In general overinflated is more common and impacts both tire wear and ride quality. Under is ok to a point, it increases traction, but it also decreases mpg. So it will decrease tire life a bit but not enough to be an issue unless it's severely low.
