Hey guys, :wave:

I am looking to buy either of the rims mentioned below, but I just can't seem to be able to figure out whether they'll fit or not. I'm confused by all the different requirements regarding offset, backspacing and on top the metric/US conversion is making it even more difficult. Maybe somebody could explain what I need to look for... The bolt pattern is not an issue, because I am planning to get adapters for the wheels.

Also, is offset always in "mm" and backspacing in "in."

KMC Monster 18x9 - Offset: 35, Backside: 6.38"
KMC Rockstar 18x9 - Offset: 0, Backside: 5"
Pro Comp 7089 18x9 - Offset: -6 Backspacing: 4.75"

Thanks for a quick response.

Thanks for the reply Anand,

So I can neglect the backspacing if I find a rim that has an offset of 75mm? Is that negative or positive? I believe to be able to remember that ET stands for the negative offset... f thats correct none of the wheels are going to work. Thats quite a bummer...

Alright, so now I'm totally confused... if it is positive offset that I'm looking for, then too little of an offset would pull the wheel inwards and a spacer would help me keep it in the right place?! This is horrible to get your head around...
