The China made tires have been somewhat problematic but I wouldn't let it be a major concern. The USA made Goodyear G614's may have been overlooked by your dealer as an offered option. Many buyers are ordering that option as they are cheaper as an option than purchasing after the fact. I must say though that over the last year, I haven't read many posts regarding tire issues. Certain brands of China tires were more problematic than others and I think the Mission brand had more than most.
Be diligent about checking your air pressure, keep them at 110 psi cold and inspect the tires regularly, both inside and out. You'll be fine.
