WHY HAVE YOU NOT SEARCHED THE TIRE FORUM FOR YOUR ANSWERS!!??!!1
Offset is the measured distance from the centerline of the wheel(the VERY middle of the wheel) to the bolt pad, ie: the spot that bolts to the car.
This distance is critical when fitting aftermarket wheels and tires, because it along with width dictate where a given tire/wheel assy will fit within the fenderwell.
Nissan's 240sx alloy 7 spoke wheel is 6" wide with a +40mm offset. It's a relatively high offset, but it's also a narrow wheel. The wider wheels require a lower offset, to maintain safe distance from suspension components on the backside of the tire/wheel assy.
