Using Metzeler Tourance (rear) tyres on GS?

[Toenis]

Hello,

Long time no post...

Ok, here I go with my latest idea - is it possible to run Mezeler Tourance rear tyres on GS both rims without getting in trouble on city streets?

I have that problem for a year now, when I must ride on gravel roads my stock tyres feel absoloutely unsafe and so on...

So, I was browsing Metzeler website an found those Tourance tyres.
Fitment chart shows that there are 120/90 17" and 140/80 17" rear tyres avialable and my question is that is it ok to run those on GS rims?

I still got superior price on those tyres so I am about to buy those Tourances.
