wheels for jeep

[puck]

Just wondering if there is any other car with the same stud pattern and off set as the JK.

I would like to pickup some second hand 16"x8" rims but not sure if any other 4x4 has a similar wheel


from what i understand the following jeep wheels are 5x5 studd..
5x5" '99-'04 Grand Cherokee WJ
5x5" '05-Current Grand Cherokee WK
5x5" '06-Current Commander XK
5x5" 07-Current Wrangler & Wrangler Unlimited JK

I dont think any came with 16x8 though.

thanks

Steelies in that size are usually available from Jeep suppliers and look great on Wranglers. They have greater offset, though which may set your tyres out a lot further than the stock wheels/ tyres.

If a 3.5 offset is normal does that mean a 5.5 inch offset pushes the wheels out 2 inches more?
Trying to get my head around the wheel offset issues.

Offset is distance from wheel centreline to mounting plate

Backspace is distance from rim edge to mounting plate

Every wheel is different but a given backspace remains the same regardless of wheel width, while offset is dependent on wheel width

e.g. A 8" wide wheel with 4.5" backspace could be Offset 0P (zero positive)
Note: The rim thickness affects measurements

8" with 5" backspace could be 12P
8" with 3.5" Backspace 25N
9" with 4.5" backspace 12N

Generally you are constrained by the amount of backspace you can accommodate on your vehicle.

So if you go wider, the backspace stays about the same, and the Offset goes more negative or deeper dish.

Changing offset will change your track by twice as much and affect your steering and increases load on wheels and components like bearings, but for relatively small changes it is not a concern.

I used to design and test alloy wheels to AS1678 in a previous life, and there are probably some guys on this site driving around on my rims.
Not me though!

JK's have a standard Back spacing of 6 inchs which is pretty poor. I dont know why they kept doing this

your getting confused with the stud pattern vs offset

Thanks for the info pdh351,

So If i want to run 285/75/16 what would be the best back spacing? 4.5?

Thanks

Thanks

If your trying to run these on your JK these tyres will fit on the standard rims.
Mine is an 07 with 7inch rim and i run these sizes with mtz's no hassels, but i do have OME lift which may help out.
