Looking to order a set of rims for my 99 cherokee. Does anyone know the specs of a factory rim?

Bolt pattern = 5 x 4.5in, or 5 x114mm(per tirerack.com)

Diameter = 15in

Width = 7in

Offset = ?

Back spacing = ?

Tirerack.com doesnt list the factory rims specs to compare aftermarket rims too.

Any info on this would be appreciated .

Thanks

 

I went with a 4" backspace. I think factory is 5.5 or something

 

Factory back space is 5.25".

If there was a site like this for XJ rims,...

 

Hmm,.. lets see if i can math this out,...

If the rim is 7in wide, and the back spacing is 5.25in, and offset of the measurement from the center of the rim(width wise) to the mounting surface of the rim,...

7 / 2 = 3.5in to the edge to the center of the rim, width wise

5.25(backspacing) - 3.5 = 1.75in

So the mounting surface of the rim is 1.75in(1 3/4in) off to the outside of the rim. Offset is measured in MM, so 1 3/4in converted to MM is 44.45mm

sound about right?
