Before getting my 19's, I thought they were too big. If the style of my 19's were available in 18 inch I would have probably gone with 18's, or even 17's if they made them. Having said all of that I'm thrilled with the 19's and wouldn't have it any other way.
My rear tires are 265/30/19. A lot of people recommend larger rear tires - 275 or 285, but I was warned to stick with the 265's and they work fine.
Good luck with whatever you choose.
