What year an model TT do you have?
When I put new tires on, I had them balanced. Honestly, I cannot tell you it has or has not helped. We did not get out as much last year as we would have liked
When I moved into our new place, I started to get bad tire wear, but when you looked at the street, you saw some serious tire scrub. So I am confident the wear is from backing into my place.
When I pulled the TT out of storage this spring, I had the tires rotated (free of charge) Tire shop was a bit surprised, as they said no one does this. But I want to keep the wear consistent across my tires.
