Very short distance yes...
but not the same as a "donut".. unless you have a "donut" tire in a 33" OD...
the mickey spares that come in cars are skinny but the Outside Dimension is the same as the other tires on the vehicle..
by running a 33" OD tire on one side of the axle and a 29" OD tire on the other side of the same axle, the spider gears will eventually detonate as the smaller tire will rotate faster than the larger one. even on an open differential.
on a locked or limited slip differential it will be even worse, and IMHO I wouldnt recommend it.
so... Very short distances only
