Description
The design team at Modern Spare has been hard at work.
As many carmakers continue to eliminate spare tires entirely, the traditional storage space they occupy is likewise being phased out.
For the Tesla Model Y, we have developed a retrofit system that allows for a clean, hidden, and secure method to store your Modern Spare Complete Kit under the main cargo floor. The system is an assembly of Modern Spare-designed components that properly hold and support the spare tire kit, completely out of sight and flush with the floor of the rear cargo area.

Easy to install with the clear instructions. I broke a plastic “clip” on the side trim piece but was able to superglue it back on. The trim pieces do take a bit of oomph to remove. Pull them straight up. You essentially lose the storage bin but you keep the original flat floor. Overall, a good trade off. The price is a bit high but I assume the number of kits they sell is somewhat limited and they have what appears to be a custom designed part. If you want to carry a spare this is a good way to go.
