Super Tires have made a new tire for the Spirit Peugeot 406, see this link. These tires are a very nice fit on the wheels as you can see. They're a nice flat fit across the tire's contact patch.
And, they also fit the Spirit Courage as well! There's a bit of flashing around many of the Spirit Courage wheels I've checked but with a tiny bit of sanding they'd be a great, flat fit as well!
