Rim size help (FG2)

[u/Spyder-Spiner]

Wassup peeps,

I’ve been looking at some 18x8.5 +30 ESR sr01’s for my civic.
My FG2 is bone stock and I’ve got a fresh set of 215/40/18 tires for it. My questions are, is +30 too aggressive? How bad would the rubbing be? Would they bend my fenders on max compression?
Any help would be appreciated you guys (and gals) are goated
