Wheel Encyclopedia

This thread lists all wheels that came on WK2 Grand Cherokees and some aftermarket as well.

Fitment and tire discussion is in the Wheel and Tire Discussion thread:

http://www.jeepforum.com/forum/f309/...sions-1141422/


A database of fitment results is in the Tire-Wheel Fitment Reports thread:

http://www.jeepforum.com/forum/f309/...mmary-2798314/


Try to stick to the following format:

Name/Style/Description
OEM WK2, WK, or JK, or Aftermarket
Heigth x Width (in inches) and Offset(mm) or Backspacing(inches)
Link to pic on WK2
Picture of wheel

Please correct anything that isn't right, and post up offsets and backspacking if you have the wheels. (It should be stamped somewhere in the back of the wheel ET##)

Notes:
OEM center bore is 71.5.
Please limit this thread to wheel information only, not tire info. This is not a what size tire thread, how much trimming, or what size lift to clear X thread. There's plenty of other threads for that, knowing the exact size and wheel fitment is the first step in that process. Offset is crucial.
This is for information only, please do your homework before buying anything for your Jeep, while I've tried to be as accurate as possible, I'm not liable for anything you buy or do.
If I used your picture, thanks. If you didn't want me to use it, PM me and I'll take it down.
HD brakes are bigger than standard duty. If you have HD brakes, take that into consideration when determining wheel selection.

measured on an 8" wheel, 56mm offset from the centerline is approximately 6-1/4" of backspacing, user posts on forums is the only data I've found on stock WK2 offset, and, allegedly applies to all 18x8" oem wheels. As I verify info, I will remove these type notes...

You might note the difference between painted and polished/clearcoated (sometimes called "chrome", but they are actually just polished) in the descriptions, to help differentiate. Thanks.

For differences see codes:
BRY Anti-Lock 4-Wheel Disc Brakes (17")
BR1 Anti-Lock 4-Wheel Disc Brakes (18")
BR6 Anti-Lock 4-Wheel Disc HD Brakes
BUX other than US, Canada, or Mexico


One of these is a turbo diesel.

I noticed this site seem to have been updated with more WK2 relevant info:

http://www.rimsntires.com/packages.j...earch&sized=18

Bolt pattern: 5x127 (5x5). Offset: 18 to 45 mm. Tires up to 800x275mm. Rims up to 26x9.5".

The site lets you select stock or lifted.

You can compare rim and tire sizes here:

http://www.rimsntires.com/specs.jsp?item=Wheel-Tire

They say the OEM 18 and 20 inch wheels have a 173 mm BackSpace, 45 mm offset, and 9 inch width

My OEMs are stamped with a 56.4 offset, however.

ColdCase, I'm struggling with this everytime I worth through it on our Jeeps. I'm almost at the point where I don't believe the number stamped in the wheel, but that's absurd.

Backspace is measured with the wheel laying flat on the ground face up, from the ground to the mounting face of the wheel.
Offset, I'm sure you know, is a measurement from the center line.
The problem is, when we say 9" wheel, that's the internal bead mounting surface, not a true cross sectional width, which may be as much as 10" in our case.
Without calculating the mounting width and overall width delta, you cannot correlate backspacking and offset.
For example, using your numbers above:
OEM 20"
6.81" (173mm) backspace
9" (228.6mm) width
1.77" (45mm) offset

half the width, plus the offset, does not equal backspacing:
4.5" (114.3) + 1.77" (45mm) = 6.27" (159.3mm) does not equal 6.81" (173mm), UNLESS, the rim's lip is 0.54" (13.7mm)

try that again with the stamped digits from Mopar
4.5" (114.3) + 2.22" (56.4) = 6.72" (159.3mm) does not equal 6.81" (173mm), UNLESS, the rim's lip is 0.09" (2.3mm)

So, That leaves us with 2 numbers for the width of the wheels lip, one being a half inch, one being 2mm.
The half inch is believeable, the calculated 2mm is based off the numbers from Chrysler.

Maybe JeepCares can come in here and shed some light on this?

I don't think I'm going to shed any light on this at all. FEEL FREE TO CORRECT ME


This is what I always thought (remember, I'm not very technical):

The wheel width is the measurement measure from the inside of each flange (lip), rather than from the outer edges of the wheel.

Offset tells you how far off center the mounting part of the wheel is.

So if you have a 56.4 mm offset – that means the tire is mounted on a “plate” 56.4 millimeters out past the center of the wheel. This actually brings the wheel /tire more under the vehicle. The mounting plate is farther away from the back of the wheel (back of the wheel being the side that faces towards the center of the vehicle – the side you can’t see) than a vehicle with a 45 mm offset.
The offset in cast into the back side of all Chrysler wheels.

Backspacing is the measurement between that mounting surface of the wheel to the back (inside lip) of the wheel - (back of the wheel being the side that faces towards the center of the vehicle as opposed to the front which faces out from the vehicle.)
Backspacing is half the width of the wheel (inside lip) plus the offset.

Some people add spacers to “space” the rim off the hub to get more backspace.
