Bad for wheel bearings, puts more leverage on them.
Illegal in many states because can throw stones into cars behind. Some states require mudflap covering full width of tire , extending to x " from ground. This is why fender extensions are made to cover larger tires. If not outside top of wheel well you can get away with it legally. Theres a lot riding around out there ignorant and lucky.
Being blunt, little tires outside wheel wells look stupid too., at least to me.
