I used the messaging feature on GangUp and APEX was able to send me a target date that is 5 weeks earlier than what GangUp indicates, mine is 4/28. Also, when they capture your deposit, an email is sent and that email contained the 4/28 date as well.

I do actually have a technical question as well. Would it be okay to reuse the 245s I have on the front and order a new set of 275s for the rear, or would it be better to just order 4 new tires and start fresh?

Would need more information on what the tire size is, is it the 245/35 that came with the ZTK? What size 275?
If it's 275/35 and 245/35, it's going to be bad for the xDrive system, as there's more than a 1% difference in circumference.
You can enter tire data
here to figure out what will work. I went with a 19x9.5 square setup for a couple reasons.
1) A square setup can be rotated to balance tire wear
2) Even though a small difference in circumference is allowed, 0% difference is ideal. I've read a few threads where owners (of other BMW models) claiming to run within the 1% tolerance had xDrive failure after 50k miles.
I prefer to run 265/35, as there are other members who have already received their wheels, I will wait to see their fitments and if the clearances aren't OK, I'll run 255/35.
