Yes I searched but can someone tell me what the wheel offset means? I know it has to do with how far the wheel sticks out or something. I bought 18" OZ Antares with a (I think 40mm) 40mm offset.

I did a search and just came up with certain wheel offsets, no explanations...

Thanks

 

You need to search better. Luckily, I saved this link to a thread where I posted a website that explains offset very well.
