18's with normal tyres will be far better for performance than 16's with Runflats
So you get both performance AND looks. If you get a light 18" wheel then they'll be even better for performance. The 18" Superleggeras and Tyres I have weigh less than the lightest MINI OEM 16" with runflats!
The only thing to understand is freewill, people have the freewill to sacrifice some extra performance for looks.
