Texture losing quality at a distance, resulting in a flicker

[HerrDave]

For whatever reason, the top of my Steam Tank's metal rim has a messed up surface

When viewed up close, it appears as it is UV wrapped

When viewed from afar, certain surfaces/triangles go blurry despite the sizable UV map section dedicated to it

How do I combat this?

Green = Displaying Correctly
Red = Quality loss for no obvious reason
