Tire Pressure question

Since I’m new to ATVs, I’ll ask the question here … I was given some advice couple days ago (from a guy I do trust), he said he inflates his front tires to 10 psi. He says it steers like a breeze and it’s easier on the plow. I understand all the "manufacture’s recommendations" stuff, but my question is, is this common? Do guys do this, and if so, does it run the risk of messing with the front suspension?

Thanks for helping a newbie!
