Tire Rack has these specs:
Size: 16x6.5 Offset: 42mm Backspacing: 5.393" Bolt Pattern: 5-112
But on Costco steelie specs sheet:
Bolt: 5-112 Thread: 14X1.50B HEX 17MM
Do they mean the same thing? I tried looking up what those specs mean and I'm not having any luck.
It's an 08 A4. If anyone can point me in the right direction, it will be greatly appreciated.

The tire rack rim specs are pretty complete.
16 inch diameter, 6.5 inch wide
offset: the face where it bolts to the hub is 42 mm outwards from the centreline of the rim width
backspacing is from the back of the rim 5.393" to the face where it bolts onto the hub.
Bolt pattern 5 in a circle diameter of 112 mm.
The only thing maybe important/missing is the centre bore size.
Costco spec tells you the bolt pattern and for some reason the wheel bolt size M14x1.5 with 17mm hex head lol.
They don't provide any other info so it's hard to say if it'll work, aside from the bolt pattern matching.
Generally most places should allow a test fit of the rims, no charge (at least CT did when i worked there)...
