Custom rims, wheel tire packages for your ride - RIMSnTIRES.com
very good graphical representation of everything tire & wheel / rim related.

 

Yes it is
I have had this site bookmarked on my PC for years and have shared it with dozens of others here
I know it is posted all over the place here too
Thanks for sharing again

 

Kind of a bummer, it doesn't go down to 125 section width. One common Mercedes spare size is 125/90-16 but a 225/50-16 is basically the same diameter and is very common. (125*.9 = 112.5 same as 225*.5)
That site has the simplest way to quickly show rim clearance and backspacing issues. I need to plug in actual crossfire stock rim sizes now.

 

Just found this post about it as well!

I emailed them, and they added 125 section width, and 90 series, so now you can directly compare some additional spare tires. Now if I can find the offset of the Mercedes 16" x 3½ rim.
