Wheel offset and Tire Calculator

[moky-tron]

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.

Around this time of the year is when we have a lot of noobies join the forum...
More noobies more questions, more threads......It's all good.

It's just you, Mr. 8th set of wheels.

Can we forward any new wheel fit threads automatically to the "rims-n-tires" page? ..traffic on this forum would go down immediately and noobies get their answers w/o sifting through 100's of posts.

I don't think I ever posted pics of my 9th set. As for my upcoming 10th, it's a secret.

sorry but i just love the gs setup on your car.. is it too much to ask for the specs of your tires, wheels and suspension. how much did you drop? is the ride comfort the same?
