Here is my BB with 245 18s in. But I do have the larger fender flare and I don't think they look "sucked in". Whatever that means ha! But maybe this will help you.
Hey DB! I'm a huge fan of them but I had the dealer install them. I would have myself but read that you have to cut the larger mud flaps in the rear to get fit and I didn't feel comfortable doing that. Living in NYC I also don't have the tools or the space to do it.
If you do take them in...
Hanging with the Mom for Mother's day in Ohio with all my upgrades finally assembled. Although...a hood decal and larger tires are...tempting to say the least ha!
I took my BS BB to the dealership to talk about two weeks ago. They said "there is no power module to allow that to happen in the first place" and "I must have been mistaken."
Suffice to say, they don't know anything about these yet.
