I can no way see myself sitting at the side of the road pulling up grass and stuffing it halphazardly into my tire. I CAN see rim damage, spoke damage, lumps, bumps, decreased shock absorbency, and ruining the tires.
If you don't like this idea talk to Scott Kaier at;

He says to "leave one side of the tire bead hooked to the rim and cram the opening with as much soft stuff as you can find. Install the other bead and away you go". "It sounds absurd, but it really works."
This is not a way to finish the last 20 miles of a ride at top speed, but you could limping home at 8 mph would be faster than walking.
