Well we should care why Nitto (and others) recommend no greater than 255s on a 17x8" rim to make an informed decision on the thing that is between your car and the road. What if it's a safety issue where the outcome is that the tire doesn't properly seal when being stressed in a turn? Might cause an accident? I am not trying to say that this is the case, but it shouldn't be just casually glossed over either for only looks. Looks are important to me also. It's good to be asking these questions so we can get feedback from people who have actual experience and get this info out there.
