I got a 2008 Dodge Sprinter 2500 for my business and I want to make some changes to it. The first thing I want to do is change out the wheels. I'm having some difficulty getting the specs to look for some wheels. I know the stock wheels are 16x6.5 but I don't know what the offset is.

I want to change out the wheels to a 17x7 or 17x8 but I need to know what offset to look for. I did some research and I believe I need something is the +50, +60 range, can anyone confirm this or point me in the right direction?

Also the lug pattern is 6x4.5 right?

THANKS for any help!!!
