the 305/45's have a larger diameter than stock tires. I'm not sure if they'll rub, but you have a better chance of them not rubbing on a WBH than on a cladded.
305/40's have the same diameter as stock...but the 45's do look nice.
when I had 305/40's with a 2/3 drop, it rubbed (cladded). It wasn't a lot, but it rubbed.
