not really looking to go much larger on the tire diameter or width....more looking for a more aggressive tread pattern....this is my first Subaru, and my first non-4wd vehicle in years. that being said I fully understand the stresses that larger tires put on drivetrain. I have been wheeling ifs Toyota trucks for the last 10 years.....so really, just looking for tread pattern over larger size..... uncharted waters for me here in subie-land so I will ask plenty of newbie questions.....thanks..
