Oh it definitely rode worse on the spare.
I was looking for a gravel pit to go set off some stuff and ended up on a sandy road and I could feel the spare cutting into the sand.
On regular roads when I would go around turns I could really feel additional body roll.

Definitely carry a little compressor.
The ultimate 12v air compressor is the ARB compressor, comes in single and double stack, but they run around $150 last time I checked for the single.
I got a nice one from Walmart for about $40 early this year. Its cord is long enough to inflate rear SUV tires and not take forever. Definitely better to air up your tire if it goes flat due to a single nail instead of putting the doughnut on.
Oh plus chances are your spare doughnut is probably flat. A doughnut with 20 to 30 psi isn't going to last very long. Most need 40 to 60psi to keep the rim safely up off road.

If you use tire slime they can't be patched.

My leaf didn't come with a spare or jack.
It had a 7 year old can of slime which I used for target practice and an air compressor that probably sux. Luckily it had the spot for a jack so I put one in and threw a spare in the back hatch area.
