Trying to find heavy sidewall performance tires, manufactures don't list sidewall plys for passenger tires.

Picked up a 2003 impreza sport wagon for next to nothing last month, and the tires are pretty much done.

I have my winter tires ready to go, but I'm having a difficult time deciding on summer/all season performance tires.

My biggest concern is sidewall rock damage, but i'm sticking with stock tire profile and willing to spend the extra cash.

I spend a fair bit of time offroad(20 miles, one way, daily) and everything I've handled so far feels like paper sidewalls, and I just don't trust them with my driving conditions. My road miles are about 50/50 pavement/off road.

So far, the only acceptable tires I've come across have been the bfg t/a advantage sport, which feel more durable, but they're a wedge type 3 ply sidewall, and I'm hunting for more plies than that(6+?). This really makes me wish that the bfg at t/a came in 205/55/16.

What would you run on a DD that sees 50% of it's miles offroad?
