TKC80 sizes for R1150GS

Hi, can anyone out there advise me of the best size/spec TKC80 tyre to fit? My local dealer that I have just phoned (In Germany) doesn't have a spec sheet for BMW bikes (!) and my hand book is back in the UK. Looked in the Conti website but there are several tyres and ratings listed, not sure which one is recommended. Any help appreciated!

The OE tyre sizes are:

110/80 R 19 59 H TL (front)
150/70 R 17 69 H TL (rear)

Dunno what size the TKCs come in though.

Hope that is of some help.

Greg

Thanks for the help!
