Highest Offset 24" Rims

[MeanGreen03]

I'm looking to purchase a new set of rims as I bent one of mine and they are discontinued. I'm looking for a 24x9.5 with a +30 offset or higher. Does anyone know of any brands that carry what I'm looking for? I've been researching a lot and am having trouble finding what I need.

Excuse the dumb question but what does the offset mean
