What offset? I understand back spacing

So I'm getting new wheels and tries. Decided to go with 17's and 285's

I think I want around 4.5" of back spacing with the 17x8.5" wheel.

Help me understand offset. Seems all the tire places around hear only talk offset. When I google, it's either or... So I can't find both to compare. When I search hear I can't find an answers just people talking about "enugh". (Also Lots and lots of high jacked threads)



Ideas?

I think it's zero for 8" and -5 for 8.5 but I don't want to own them only to prove my self wrong.

I think the closest you'll find is AEV wheels. 17x8.5 with 4.75" backspacing. Yes I know their website says 5.2" backspacing but my pintlers measured out at 4.75". Several of my steering components require 4.5" backspacing on their websites and they work fine with my AEV pintlers.

Most aftermarket wheels seem to be 9" wide with 4.5" backspacing.

I know that doesn't answer your question about offset though...

Backspace is the distance from mounting flange to inside of inside rim...
Offset is the distance from the mounting flange to the center of wheel...
