There are significant portions of a number of spacer/adaptor threads that cover this issue. As mentioned the Blades will fit without trimming the studs, but most of the other OEM wheel options will.

If you order from the linked website you need to separately specify via a message to the seller that you want the 15 mm ones.
Yes, the only difference between the 15 mm and 17 mm is the 17 mm will push the tire 2 mm further out, and it won't make any difference at all to how the wheel fits on the studs, as the spacer studs are (or should be) the exact same length.

1. 12.5 x 1.5mm (default)
2. 12.5 x 1.25mm
3. 14 x 1.5mm
4. 14 x 1.25mm

Do you know which bolt is the correct size?

And, thanks so much for your help and guidance. I'm grateful.
