For the Hyundai Tucson, can the spare be stored under the rear cargo floor when the foam insert is removed?

Yes. Please read below for further details.

For Hyundai Tucson Hybrid Models, there is space under the rear cargo floor that is a great place to store your modern spare. There are important details to consider. 

For some model years, when the foam insert is removed, you may notice small bolts protruding upwards from the floor of this storage space. To store the spare in this space and avoid having these bolts cause damage to the spare, you must place some type of protective material over these bolts before the spare is put in place. 

The presence of these bolts varies by model year. If they are not present, no precautions are needed. 

The Hyundai Tucson Hybrid is available in a Plugin Hybrid variant. These models may not have this space available as it is used for the battery system and related components. For plugin hybrid models, please choose the kit option with the carrying case, which was designed to store the spare kit in the main cargo/trunk space.
