The wheel spacing itself will correct, or increase, the offset and properly push the wheel out. The spacers can also be change out to provide a better spacing and offset.
34-45 offset
Is the estimated tuck in or out from the center of the wheel, example: (nissan sentra) 18x7.5 +40 offset is tucking in 40 mm from the center of the wheel or (old chevy pickup) 15x7.0 -10 offset is sticking out 10 mm from the center of the wheel.
The stock wheel has a 55 mm positive offset. Positive offset means that the wheel is tucked into the fender well 55mm more than it would be if the bolt flange of the wheel were perfectly centered in the wheel. Negative offset means that the wheel will stick out of the fender well more. So........ If you reduce (55mm-45mm) the positive offset my 10mm, your wheels and tires will stick out of your fenderwells 10mm further than the stock wheel, assuming that the aftermarket wheel is the same width as the stock wheel.
+45 offset
+45mm offset (6.25" B/S)
2008 Honda civic steel 16" wheel 45mm offset
4x100mm offset +45mm
High Positive Offset +35 to +45
The offset on a Jeep Wrangler Sahara wheel typically ranges from +30mm to +44mm, depending on the specific model year and wheel size. The offset is measured from the wheel's centerline to the mounting surface, and a positive offset means the mounting surface is closer to the outside of the wheel. It's important to check the specifications for your specific Wrangler model to ensure proper fitment and performance.
