Heavy when full'o'crud.

No more flats, no more fixing them on the side of the road (usually in the rain as well).
I see some serious advantages for commuting.

May indeed get heavy when riding in the mud.
Then again they'll probably fix that once they notice the problem.

The lunar rover also had airless tyres way back in the 60s: http://en.wikipedia.org/wiki/Lunar_Roving_Vehicle

You've seen the past.
