The grievous tire theme…

Dear G-meinde! After having broken a tire yesterday, I have to prefer the tire theme. I drive the original Pirellis Scorpion in 19. Good road tires, in the terrain rather not so dolle. Sure. Now I am looking for a compromise, in order to continue to be comfortable on the road and still have reserves in the terrain (5-10%). I don’t know much about tires, but on my search I have to notice that I am apparently not so well positioned at 19. So I ask I don’t know if I should change to new rims right now… but which size is useful and possible? Sometimes I want to be able to drive at least 180. Of course I think the rugged off-road rims are great but I also want to be able to cruise in the city relaxed without the consumption rising to 25l, because the rolling resistance is gigantic… Oh yes, I drive a G 500 from 2017. I know that there are x posts on this topic but I can’t find anyone who really brings me forward t. So again in short: Which tyres / rim combination would you recommend to me for my requirements? Thank you for your help, Tobias (G993) from Brandenburg
