Question re alignment of gear legs

[GAHorn]

I fly off grass at home...so that means that most of my landings are still on concrete. (Yep. The majority of all my landings are elsewhere because I virtually always fly it to go somewhere.) Some of my taxi's are quite long as well. Austin-Bergstrom (9000 and 12500 lengths,...I almost never accept intersections.)
My former set of tires were given away after 5 years to someone who installed them on their Cessna, when I decided I wanted the cool look of diamond-tread. I now have almost 300 landings on them and they look new. As compared to many other Cessna's whose alignment appears somewhat off considering their high-wear patterns.
