After much trial and error, just uploaded a couple of photos into Gallery (file name New Shoes) showing the 15X6 Rials on our white/silver Passion. How obsessive can I get? Just replaced the gray plastic caps on the TPS valve stems with the bright silver ones used on late model Porsches! (NOT the fancy accessory caps with the colored Porsche crest!)
You might consider going to the matched front and rear 175/55 or 195/50 tires. You've probably seen the other threads on this.
