Balancing Weight and Efficiency: To improve battery efficiency, electric vehicles require lighter weight. Spare tires, as additional weight, add to the overall vehicle burden, impacting battery range and performance. Therefore, manufacturers consider removing unnecessary weight, including spare tires, during design.
Space Constraints: Electric vehicle batteries typically occupy a large portion of the vehicle's underbody, leaving chassis space very limited. To maximize the space available for batteries and other critical components, spare tires are often omitted.
Tire Technology Improvements: Advances in tire technology have made modern electric vehicle tires more durable and wear-resistant. Furthermore, the design of electric vehicle drive systems and battery management systems takes tire durability into account, ensuring the vehicle can operate normally even without a spare tire.
