Will it destroy the differential?

No, it's more of a safety issue. The walls on spare tires are really thin. If you are ever in a position to make quick turns to dodge something, the spare tire is likely to pull off the rim or will just blow. Also, you want most of your car control in the steering. Having that flimsy tire up front is just not a good idea.

also, you will notice the tread patter on the spare tire doesnt have much on the shoulder of the tire. Not good for turning. Spare tire will last longer if you just put it in the rear.

OMG the tire will never pull off the rim or blow up from a quick turn. The only reason you want it on the rear is because of reduced traction for steering and braking. It wouldn't pass DOT safety as a passenger tire if it blew up because you turned too quick.

There's a vid on utube of Chris Harris drifting a AMG Mercedes with 4 of them on.
