Clueless About.......

Any help would be appreciated!

My girl has finally had enough about me whining about the knackered 16" (195/45/16) wheels on my Cabrio, and has taken it upon herself to buy me some RH Raiders (I think that's what they are) for christmas.

They need a bit of tidying up, but here they are:

They'll need new tyres, so I was wondering what you guys would recommend?

The thing that I do like about my current wheels is the way that they fill the arches (my car is running stardard height), will I lose that look going down in wheel size, am I best to get some sort of lowering kit (if so, what kind) or will increases tyre size do the trick?

Sorry it's a bit wordy, and probably quite straight forward but I'm keen to learn but currently know very little about such things :?

Thanks
