Stock 20" Wheel Dimensions - offset backspacing
 
I had a hard time finding this info here and could find no definative answer to the 2006-2008 stock 20" Sport wheel dimensions so I'm making this easily searchable for posterity.

Definatively.

Stock 2006-2008 20" Sport wheel size is:

20" X 9"
Offset is +19mm (+ 3/4")
Backspacing is 5 1/4" ((9"/2) + 3/4")

For those of you doing the math, yes I realize the numbers are a little off as 3/4" is technically 18.75mm when converted but I doubt the extra 1/4mm will affect much.

I don't know why they use metric for offset and SAE for backspacing but I can tell you the most popular sizes of offset (6,12,19 and 25mm) all are the closest whole mm sizes that round off to SAE measurements increasing in 1/4 increments (1/4, 1/2, 3/4 and 1").

For those interested, the true offset in inches is 0.74803" and the true backspacing is 5.24803" for the 20s.

Thanks.

Thanks for sharing all that info man! That will come in really handy for some people that are searching for that info. I was looking for it when I was buying some rims as well.

Yeah, I was surprised how hard it was to verify.
