My Crosstar's original wheels have these specs:
PCD: 4x100
Center bore diameter: 56.1 mm
Wheel size: 6.0x16 inch
ET: 45 mm
Lug nut seat type: R12 ball shape (This one is only important if you want to use the same lug nuts that came with your Crosstar.)
Although not officially approved by Honda, I bought 15 inch winter wheels for my Crosstar. That way I could fit winter tyres with a taller sidewall, such as 185/65R15, or 195/65R15. Specs of my winter wheels:
PCD: 4x100
Center bore diameter: 56.1 mm
Wheel size: 5.5x15 inch
ET: 45 mm
Lug nut seat type: R12 ball shape
Brand: Etabeta
Model: Eros

PCD: 4x100
Center bore diameter: 56.1 mm
Wheel size: 6.0x15 inch
ET: 50 mm
Lug nut seat type: R12 ball shape
Brand: Brock
Model: RC30
