Tubeless tires are actually an old idea (they predate the pneumatic tires). The reason they're not widespread is the ride can be extremely rough and not as efficient. The other downside is that the additional shock gets delivered to the wheels themselves so while you don't have to replace your tubes or pump your tires up, you may have to fix your wheels more frequently. I learned this because I thought they were pretty cool and wanted to get a low maintenance belt drive bicycle with tubeless tires, but ended up with a belt drive bicycle with pneumatic tires (Priority Continuum)
