2001 Z71 4Door Tahoe Wheel Offset??

[HOU1PTT]

I have a 2001 Chevy Tahoe Z71 4Door (4X4)... It has stock wheels... 17X9 (mesh looking wheels).. I am looking to get new wheels & would like to know the info on the stock wheels.. Looked all over the internet & got 15 different answers...

Bolt Pattern?
Offset?
Back Spacing?

*** Last thing, I would like the new wheels to stick out about 1" over stock.. For now I would just settle for the CORRECT stock numbers..

Thanks In Advance!!
