Hello: I recently purchased a 2006 LX 470. It came with stock 18 inch tires and the stock Lexus chrome wheels. I don't like the chrome look and I am thinking I would like the look of 20 inch tires/wheels better. I am thinking 22 inch would be too much. Does anyone have any recommendations on what tires to get and where I might purchase some good wheels? I am in San Francisco.
