This might help,

Note on Insertion Depth (ET): ET = Einpreßtiefe or "Insertion Depth" in German - SAAB decreased the offset as the rim got wider in order to maintain the same backset, as in this quick chart:

Width Offset ET# Notes

5.0" 45mm ET45 Early 99 rims
5.5" 40mm ET40 Stock 99/900 rims
6" 33mm ET33 Stock 9000 rims
6.5" 27mm ET27 6.5Jx16 Aero and Super-Aero Rims


A great source for SAAB wheels is Ronal - www.ronalusa.com . Ronal made many of the original SAAB wheels and still makes compatible ones for Classic SAABs as well as for NG 900's, 9-3's and 9-5's. They offer 14-17" wheels even for older SAABs. See their wheel selections on their web site, INDEX of CARS section, Saab--older 4 lug...or go to Ford Focus for most current wheel styles and sizes. These same wheels and sizes, in different offsets are available for older Saabs.

Thanks for the info... always wondered what ET actually stood for.

Are you sure about those numbers? After Googling I've found lots of references to the 9-5 using a 49mm offset for the 16x6.5" wheels and 42mm for 17x7" wheels. However, there is some contradictory information here and there.

I found a PDF of a 2005 9-5 manual that says this:

NOTICE
Wheels larger than 17” must not be fitted.
Wheel offset must be 49 mm.
Vehicles with 12.05” in (306 mm) front brake discs must not use
15” rims.
