I'm waiting for them come in. Still have time to decide on the tire size. But I also ordered a leveling kit from rough country. 1.5-2 inches. I think that should give a bit of some room. I read that you went on a trip 1k miles? No issues with 275? That's also one of my worries. Might be way too...
I'm thinking about getting the same rims. I also have the same color and car. So no lift at all? No rubbing? And you're able to mount 285/70? I'm thinking 285/65 or maybe 265. And 2 inches leveling kit install the front.
