My son lent a bike to a friend at the weekend, he rode it about 10 yards with a flat tyre (it took him that long to realise what was wrong and stop). The wheel was fine, but there were 8 pinch punctures in the inner tube, as well as the original puncture.
So, plan A would be 'It's ok if you junk your tubes rather than repairing them.'
There's also a significant risk that you'll ruin the tyre by putting all the weight on the rim through the side wall.
You'll also have little control of the front wheel, it'll go everywhere except straight ahead.
And no braking power at the front end.
And when the tyre does roll off the rim, you'll be riding with the metal rims on the tarmac, which will scuff them and possibly cause sharp edges to puncture your newly installed tyre and new tube.
In general, I wouldn't recommend it.
