Offset and Backspacing for Dummies (like me)

So I don't know if this is a repost, but I found this information very useful in my search for tires. I have read tcBob's post about understanding offset but this also helps for us visual learners that need pictures.

 

This is a great resource for people who need to convert rim width and offset to backspacing. When people are first starting out shopping for wheels, very few understand that the backspacing is the single most important component, because it is caluclated from both rim width AND offset. This chart is a great resource for those needing to see if a particular rims fits their needs.

 

I wish it had other offset number's cuz I've seen a few +10...Its probably around the same backspacing as a +12 tho.
