Rim Offset - How to measure it and get it right

I have just grabbed a screen shot of each of the Manuals we host here for reference.

So the 15x7 rim on the early GQ is a Pos5

Attachment 52545

The 16x8 rim on the GU is a Pos10

Attachment 52546

and the 17x8 on the later GUIV and onwards is a Pos10

Attachment 52547

The offset for the Splitties are also listed

I also think the GQ Alloys in a 16x8 are a Pos10 also.

Thanks for sorting that out MR and there ya go, told ya I'd never owned a rim with that offset :o

Interesting thing is it makes every one of us running -22 or more illegal :210:

Ah well, shit happens.:049:

That's interesting as to get steelies to fit I had to go to the 16" -23 kings, nothing else would git over the front calipers except the original alloy wheels.

Not good if its illegal.

Thank you very much guys for that informative information about the offsets. I think I think might just drive the MQ all the way to brisbane and fit 1 on the back and front to make sure they are all good before I purchase them. Have a nice week "PATROLLERS" LOL

so helpful! love it

thanks for this great information. Good info anyway.

Referring back to story about wrong offset rims supplied new from retailer.
That maybe a common practice, She'll be right, he wont know the difference or notice!!.
Lucky I fitted the spare back on and did notice the stamped offset, fronted salesman that it was not as ordered, he came good.

Some may say, so what! wanting oem specs offset to help ensure less chance of the dreaded wobbles, bump steer issues etc.
Yep offset may not directly cause a wobble but when ya add up any changes to geometry it may help combine to , m2cw.
In the end settled for GQ ti alloys for the std oem offset and quality brand name tyres, +90 000 k's later still steers like new , albit mainly Rd k's.

This site: https://www.wheel-size.com/, lets you search for tyres and rims of every vehicle.
You can also find which vehicles fit a certain rim or tyre.
There are calculators to compare OEM tyre with whatever you fancy as well as OEM rims with aftermarket.

See this example for Patrol 98:
