Recommended / stock wheel size for 6n2 gti

First of all, hello! I'm new to this forum, but have been using it a lot to find things out. Very usefull site.

I have recently bought a 51 plate 6n2 gti, 1.6 16v, I love the car, been slowly getting it up to scratch as it was a bit knackered when I got it, nice amazing condition leather interior,  loves it!

Now my problem is that the car has wide rims and stretched tyres, which I don't want (the rims are rota grid drifts I think. They look wicked, sad to see them go but I want standard size alloys and tyres). I'm no good with wheel/tyre sizes so I was hoping someone could recommend me something good? Or tell me the exact specs I need so I can order a set. I want 14/15's, not a fan of low profile tyres.

I tried looking online for this info but was struggling.. and couldnt really find a thread on it. 

Any help much aprecciated.
