Well.
As far as bling wheels go, those aren't a bad shape for the Range Rover. They should be one size smaller, with a larger profile tire, to balance with the meaty shoulderline of the truck. As well, I think they should be gunmetal grey powdercoated, instead of chrome, ala the LE Discoveries. It would keep them from sticking out like that.
Hey, at least it doesn't look completely awful. It may be a silly use for a Rover, but at least it doesn't look as bad as some out there. The shape seems to work with the body lines.
That will never look as proper as a set of mud tires, but they guy didn't do half bad. Follow my instructions above and they could look factory.
Still, not my cup of tea.
Cheers,
