Just figure I'd do an update for anyone who may interested in RRW wheels and the offset in the future. Starting with RRW- the wheels are beautiful and their shipping was fast. Weighed them and they sit at 26lbs each. I had actually chickened out over the -12 offset but when I went to cancel the order they had already shipped. I think it was a week from order to receiving them. The downside was that I had messaged them twice asking for info about knowledge of rubbing and there was no answer whatsoever.
I got them installed with a set of 265 Wildpeaks and there was rubbing on both the mudflap and a bit on the fender. Did the standard liner pushback and trimming (Took off about an inch) and they were good to go. In the end I'm really glad I got the -12 because it looks perfect and I LOVE the wheels, but I'm not a fan of nonexistent customer service so I would think long and hard about ordering from them again. I think I'll be keeping these around for quite some time though.
