Question

[Matt]

Do you know the stock width & offset of the moabs? Or the width & backspace? I can't remember off the top of my head

They are the same width as oem XK wheels.

It looks like the 17X7.5 Moab wheels are at about 6.25" Backspacing (44.45mm Offset). So with a 1" spacer it is equal to a wheel with 5.25" backspacing and a 1.25" spacer at 5" backspacing?

They are the same width as oem XK wheels.

They have a different offset by half an inch. Wont clear the bolt with stock tires and no spacers

Lol. For stuff like its its quicker to figure it out on my own than finding a calculator.... especially on my phone.

Ya know, its a simple enough equation maybe ill make up a quick excel program to do it and post it so people can download it....

Good idea and then sticky it for others to find easily.

Yup yup.... 7.5+1= 8.5" which means the centerline is at 4.25" backspace. 44.45mm offset is 1.75 inches. Add the offset to the centerline position and you get 4.25+1.75= 6" backspace.

So there 7.5" wide with 6" backspace.
1" spacer = 5" effective backspace
1.25" spacer = 4.75" effective backspace

Thanks Matt! I now understand how this works Just picked up a second set of Moabs today!!!
