Saab ('92 > 390kKm) did really well on humble steel. Everything from Stuttgart to > Munich at 180km/h to muddy cow paths in Latvia. There never was or > will be be another car like this. > Opinions? I would go for alloy wheels, rather than steel, but can't cite any "scientific" reason for that - perhaps weight? The correct ratio would be 205/55 for 15" (standard C900 wheels). On normal 5.5" wide they would be a bit too "fat". On 6" wheels off a 9000 they would suit a little better but the track would not be any wider - in fact it would be 2mm narrow, but who's counting :) There is a wheel you can get, which is an official SAAB wheel and 7" wide - the offset gives you an extra 3" width in the track and is perfect for 205/55 tyres. IMO, this is a better solution for the C900 than 16" with low profile tyres. The wheel in question is: < yles/Five-Spoke%20(15x7).jpg> < yles/Five-Spoke%20Dark-Inset%20(15x7).jpg> I have seen a few of these wheels come up on eBay in Europe - Belgium and France, particularly, but also Estonia. I was looking for a set myself recently. Paul 1989 900 Turbo S
