Informed decision or, not re 15 vs 16 tires

I'm migrating from the Casita camp to the Airstream camp and there is just as much controversy about GYM on the Casita forums as in this forum. I purchased a preowned 2009 Casita in November 2010 with GYM. The GYMs are not balanced at the Casita factory and there is an included document from GY stating why they don't need balancing.
On our trip to Glacier Natl Park I found one tire wearing funny and had to get the spare put on. Luckily no issues coming back home. Switched to Maxxis 8008 tires and had them balanced. I now have about 5k on them and they don't show any abnormal wear.

Do the GYMs from AS come balanced?

The manufacturer saved a few minutes and a few dollars in weights in not balancing the tires. Out of balance tires will beat a suspension up badly as the wheel hops down the road. I have seen the front wheel hoping on a car and the steering wheel is vibrating in the driver's hands in a blur of motion.

Ever wonder what it is doing to the trailer frame, springs and shackels and structure of the body?
