Does anyone have good ideas of how to secure a spare tire in the boot of a MCS? I'm going to non RF and will be getting a donut spare and wanted some advice on how to secure the spare in the boot. I've heard that having an unsecure object as big and heavy as a spare in an accident can be very dangerous. Some people are putting their spares behind the passenger seat and moving the seat all the way back but that won't be an option for me since I will need to use the back seat to transport a child.

TIA
