Alloy wheel noob here....

Can some1 tell me is these wheels would be ok on a mk4 polo? Tyres are 195/50/15 but i maybe getting new ones if so what profile would be best........

As long as they are 4 x 100 fitment then I think you should be fine.

195/50/15 tyres should be ok on standard ride height but if you go lower you may wanna revert to say 195/45/15 or narrower for maximum arch clearance.

Hope that helps.

Ok cheers dude. They are 4x100. I will try a test fitment when i get them on standard ride height.
