1. The rim is out of spec - return it or exchange it. Chinese or not $400-$500 is still $400-$500.
2. The rim is in spec - Use the tricks to mounting tight tires (putting them in hot water, soap them up, mounting technique, etc...) or change tire brands if its more important to be able to remove and mount by hand on the side of the road.
Modifying the wheel is not a good idea for many of the reasons listed on this thread. What you need to be considering is why are Chinese rims cheaper? Are they the same quality (materials, workmanship)? If your answer is no then that's more reason not to modify them.
You forget that the OP has already used all of the tricks and knows every single one that can ever and will ever exist. They just wanted you to say "yes you should start sanding down your rim it is a smart idea and you are a bigly and smartly person who came up with the greatest idea"
