Found the answer, thought i'd post in case anyone else wants to know
OEM Fitments
For reference, the OEM MY00-03 (AP1) wheel sizes and offsets are as follows:
Front:
16" x 6.5", +55 offset, 205 tire
Rear:
16" x 7.5", +65 offset, 225 tire
and the OEM MY04+ (AP2) wheels (including MY06) are as follows:
Front:
17" x 7.0", +55 offset, 215 tire
Rear:
17" x 8.5", +65 offset, 245 tire
I presume this is correct for the UK models?
