Tire chains on a Subaru?

Your option is to buy all seasons that are rated average to good at least in snow, and KEEP THEM current. The will not perform as well on ice and maybe a little noisy. They are sold and perform decently. That’s usually not the case with original equipment tires.
AWD cars should NOT be driven differently than FWD cars. They are not off road, only safer in the same conditions. Don’t expect more.
