18's with 275s on a Duster

72blunblu, you can disagree if you want, but even in your post quoted above, you talk about offset plus or minus this or that , but then TO BE CLEAR,you explain what the backspace is.
If offset is so self explanatory, why mention the backspace?
The op says the wheels he is looking at are +35 mm offset. That dont mean dick to me, unless i convert to inches, and then try to figure out which way "+" is. Tell me the backspace, and i KNOW what the wheel looks like.
Soo. 9” wide wheel is 4.5” with zero offset so when someone says +35 they are adding 35mm what’s roughly 1.375 so what would give a total backspace of 5.857 roughly. Not that hard to figure out.
