I've already done a bit of research about this before.

If it is 95% city and/or highway driving, the Dueler H/T is a good compromise already. It has enough traction for the occassional off-road excursion while providing decent on-road grip. I've taken the Rav4 with near bald Duelers up steep muddy hills in Antipolo and it didn't fail me.

The other choice is the Goodyear Fortera or Michelin Energy XMV as it really is road based tire (though grip levels off-road is very minimal) although I highly doubt that they carry a 265/50/R16 size. You can also try scouting for BFG tires as they have good reviews abroad although I have to locate a dealer here in Manila.

Try checking out also if they carry Dueler H/Ls for your tire size. These are the direct competitors of the Fortera although the tire size is quite limited. Check out the Bridgestone store at The Fort.

To note that an A/T spec tire has a poorer on-road wet weather performance but it has the ability to handle tough terrains.

If you want maximum on-road grip - then it is time to change your tires & rims to high performance models (though the cost of this will really hurt your wallet). Look for tires with a V-shaped tread design.
