[Overdrive]

Lots of tires these days are made with a little extra edge on the tire's lip to give the wheel's rim a little bit of protection against curbing. It's still possible, but in many and most cases it does the job. It can make some tires look a little odd, but I can appreciate the function behind it.

If you want something wider, why not just get wider, better looking wheels anyway to go along with a wider tire?
