Confirmation of Stock 20" Wheel Offset??

[MCF34]

Anyone know for sure the offset of the stock 20" wheels? I am looking to get 20" chrome wheels and want to make sure I get the correct offset. A local wheel place is telling me to go with a +35mm offset.....

I believe it's +30 stock

Yup. The new tahoes are plus 30

Not that it's a big difference but I think it's actually +31mm.
