I've ordered Crossclimate+ as well. Coincidentally, I have 27K miles on my 2018 (delivered 12/17) Clarity and the OEM tires have become downright dangerous in light snow (the treads still look pretty good so age probably contributes). I almost crashed going slowly around a corner. It's gotten pretty bad on wet pavement too. Until I get the new tires installed, I only drive the Clarity on dry roads. When the car was new, I was impressed with snow handling so beware if your tires are getting to 3 years old. The Crossclimate2 is not currently available in Clarity's size but don't worry that you're getting an obsolete tire with the Crossclimate+. The below video explains the difference (probably accurate because Michelin supplied his tires). The Crossclimate+ was designed for the needs of European drivers while the CC2 was designed for the US market. The CC+ has better handling and braking in dry and wet conditions (according the Tirerack tests) while the CC2 should be better in the snow and last longer (according to Michelin). For folks here, the CC+ should also provide better fuel efficiency/range than the CC2 (again a greater priority for European drivers). The major plus for us is that the CC+ will provide superior performance to OEM on all aspects except range.
BTW, the CC+ also has a higher load rating (important for a heavy car like the Clarity), temperature rating (A vs OEM's B), and speed rating (Y vs OEM's V) compared to the Energy Savers.
