wheel backspacing question

Okay so when I get rims with my rear ones I need to pull them alittle closer in. But the thing is I've never really attempted to understand backspacing and that. So my question is what is the stock backspacing on our rims and what are some options of moving it in some?

Couldn't tell you what stock is, but to bring the wheel lip inside of the fender, go with a higher backspacing.

You definetly want a higher offset. To break it down a little to make it a little easier to understand is the higher the offset the further in towards the frame the wheel will be. And the smaller the offset the further out towards the fenders the wheels will be.

As a rule of thumb I try to not even think of wheels with less than a +35 offset for Rangers. But there are variables to offset as well. For example. A 18x7 wheel with a +35 offset will fit differently from a wheel that is 18x8 w/ a +35 offset. This is because when they measure offset they go off of the center of the wheel.

Good thing about working at a wheel/tire shop is I can bring home whatever I want to test fit before I'm committed to buying anything =) If you need more help with it hit me back and I will see what I can do.

you could always shorten your axel, some wheels have a maximum backspacing. My Centerline wheels were custom ordered with a maximum backspacing of 5.5" and that still wasn't enough for the back. The term backspacing is the distance from the edge of the wheel to the mounting face




Offset is a little harder to understand, to get the offset of a wheel first find the centerline, and the offset is the distance from the mounting face to the centerline of the wheel. It's almost always expressed in milimeters, and either positive or negative. If the wheel has a positive offset that means that the mounting face is in front of the centerline relative to the face of the wheel, If the wheel has a negative offset that means the mounting face is behind the centerline relative to the face of the wheel. Found some diagrams hope this helps man.

Also if you need to convert offset to back spacing simply divide the wheel width in half, and add the offset whether it be negative or postitive. Ex say the offset is -35mm on an 8" wide wheel.

8"/2 = 4 + the offset (-35mm)

= 4 + (-35mm) and [35mm = 1.379"]

=4" - 1.379"

= 3.621" backspacing

awesome.. Im going to have to take some measurements this weekend and see what Im looking at.

very informative thanks baha now i understand all this stuff. great teaching aids!

u soooo smart baha!
