They aren't exactly the same in the way that they are totally different altogether. The Granada/Scorpio was the next size up to the Sierra/Sapphire. It's like saying a 3-series is close enough to a 5-series.
Lots of places do custom wheel work; especially on steel wheels. Look up a place that supplies the local dirt track racers. They get some inhumanly wide custom steel wheels made.
The guy who did it said he went to a shop that does lorry wheel repair. (the guy's in the UK, that's what he said) If they do it on lorries, then they know what they're doing and it can stand up to the abuse of a simple mercedes. Sounds like good logic to me.
I want to see it done to just about any old steelie. A mid 90s accord would be sick on a set of widened steelies.
Those are Yokohama A048 tires. The only reason I can figure that he'd have R-comps on the front and...lawn tractor tires on the rear would be that it's a drift car. Besides that, I'm out of ideas.
