How a Thin Spare Tire Can Improve Your EV’s Efficiency

Electric vehicles like the Tesla Model Y often come without a traditional spare tire, but a clever new solution from Modern Spare offers a game-changing approach. Based in Utah, Modern Spare designs slim, lightweight spare tires that fit seamlessly under the Model Y’s sub-trunk floor, providing peace of mind for drivers without sacrificing space.

Interestingly, testing showed that switching all four tires to these skinny spares can actually improve efficiency. On a nearly 47-mile loop, energy consumption dropped by nearly 10%, meaning more miles per kilowatt hour—making it a surprising boost for EV drivers focused on range. The secret lies in the smaller tire width and optimized design, which reduce rolling resistance.

Installation and Practical Considerations

The spare tire kit is designed for easy installation, with minimal modifications required and a user-friendly setup. The tire diameter exactly matches the original tires, ensuring the Tesla’s systems like the speedometer and drivetrain remain unaffected. Plus, the design keeps the spare hidden and protected, so Florida drivers won’t lose any cargo space or disrupt the clean factory look.

For Florida used car shoppers and EV owners, this innovation highlights how smart automotive accessories can enhance reliability and performance. At Florida Auto Center, where we focus on reliable vehicles and automotive insights, keeping your car ready for anything is key. Options like these spares offer additional security against unexpected flats while potentially extending your EV’s range.
