Running tires wide also has a purpose, not that that is what he is going for. Most of the people running retarded stretches don't need to be as extreme as they are anyway, so the purpose is lost.
The question was not if it was practical or asthetic, it is if it can happen. You'll find people are running 275/35/15's on stock 15x6 wheel Integra Type-R's for certain race classing (DS) because they still provide more grip no matter how buldged and feel reduced they are.
