Re: Change out spare for full size tire?
I know that this is low probability event, but be sure to secure the tire if you mount it face up. The lid won't keep the tire in place in a bad accident (such as rollover). You'd hate (or a passenger in the back seat) to have otherwise survived a bad accident to be killed by a tire that popped out. The tires are very heavy and will pop out if not secured down.
Again, I realize it is a very low probability event but there is a reason the tires are bolted down in the compartment (and not just to prevent squeaks).
