You can approximately calculate the backspace... it's equal to offset + (wheel width)/2 …. If a wheel is +40mm offset and a 7" wide wheel, backspace is 40 + 177.8/2 = 128.9mm or approximately 5". It's not precise since the spec "wheel width" isn't quite the actual width of the wheel, but it's pretty close.
Does anybody have one of these kicking around they would be willing to post . I hit o pot hole last night and put a big dint into the side of one all I have is a space saver . Eather a 15" or with a .195 60 r15
