Which way?

Personally I like the white walls and full wheel covers.

I found the pics of it with the wheel covers off in the thread you linked.

In my opinion pulling off the plane steel wheel look requires everything be clean. Get some white letter tires, clean and paint the wheels and finish it with some chrome lug nuts.

Until you can do that stay with the wheel covers and clean those tires. Comet or Ajax on a scrub brush will get those white walls looking like new (but may not be good for the tire…. It's what I use and have never had a problem)
