The XB has a 45mm offset.  Replacing the 16x6.5 rims with a 16x7 rim means the overall width will increase 0.5" (12.7 mm).  So if you want to keep the tire centerline in the same plane as the OEM setup you need to increase the offset by 6.3 mm, e.g., to 38-39mm.  38mm and 40 mm offsets are commonly available.  With this choice the tire will project inwards and outwards and additional 0.25".  The Comparator cited above, for a 38mm offset, calculates a 0.3" added outward projection (resulting in more body splash!).  The added inward projection does not result in a clearance issue (as per my experience with my new wheels with a 38mm offset).

Anyone who is knowledges about lug pattern Please Help!

 I got a good deal for a set of rim 19 X 8.5 with a lug pattern of 5 X 114. Will this set fit for our  XB's 5 X 114.3 lug pattern?

Thank you for your reply
