Maybe this is a dumb question, but so what.
I currently have Mickey Thompson Classic Lock wheels (that i want to get rid of) in 15x8. According to their website they have a -30mm offset with 3-5/16 backspace.
I dont understand how the offset and back space can equal just over 4 inches, but still have a negative offset.
I've looked at all the pictures and stuff online, but still dont understand.
