Lexus RZ450e Spare Tire

The Lexus RZ450e, like many luxury vehicles of its class, does not come with a traditional full-size spare tire, as it prioritizes space efficiency within the vehicle's design. Instead, it is equipped with a space-saver spare tire or also known as a "donut", which is designed for temporary use in the event of a flat. The size may differ from the regular tire size of the vehicle, and is usually smaller and narrower. It is recommended to drive at lower speeds when this spare tire is in use, and to replace it with a regular tire as soon as repair or replacement of the original is possible. To ensure the accurate spare type and size for the Lexus RZ450e, it's best to consult with the vehicle owner's manual or to communicate directly with the manufacturer or authorized dealer.

Lexus RZ450e models manufactured from 2023 to 2025 have tires with overall diameter ranging from 29.1" to 29.3", allowing the use of a temporary spare tire with a near same diameter as the OEM tire. Tire diameter and wheel diameter clearance have been taken into account for the specific Lexus RZ450e years and trims.

Listed below are compact spare tire sizes that can fit some Lexus RZ450e vehicles based on acceptable tire diameter range of 28.2" to 30.2".
