While this has been discussed numerous times as well as the suspension thread, for new members and old members alike, sometimes we still do have offset and tire calculation questions.

i have found 2 sites which may be key to helping us all understand wheel offsets and the like. these two sites calculate the difference when upgrading from OEM 16" or 17" wheels and tires to something bigger like 18", 19" or 20"

to also help us understand offset, here is a simple diagram which i have posted in several threads which some people might not see.

regarding flush and not flush fitment:
regularly we encounter the terms flush fitment. to clarify things,
FLUSH fitment means how well-lined up your wheels are with the fender.

here is an example of LOW OFFSET AND FLUSH FITMENT

on the other hand here is an example of a HIGH OFFSET AND NOT FLUSH
sometimes it also is referred to as "tucked in"

hope this helps us all in understanding offsets and FLUSH fitment as well.
