BF Goodrich makes a tire they call an All Terrain/KO that works well on this
sort of road, but I can't imagine it would work very well on your BMW.
My guess is that the dirt road isn't wearing your tires out.
I agree. I live on gravel; in fact both houses and my cabin are on gravel.
My Michelin Pilot Sport MXMs don't wear out because of it - they wear
out because of regular (asphalt/concrete) road travel.
You don't say what model Conti you have, so we don't have alot
to go on here.
If it rains a lot where you are then stick with the Continentals.
Most BMW drivers press on, but even so are unlikely to reach the limit on
public roads in the dry.
OTOH it is all to easy to unexpectedly find the limit in the wet even when
not pushing it. This is where Continentals (and their boast of "The Rain
Tyre") come into their own.
