Lexus RX350h Spare Tire
The Lexus RX350h offers a temporary spare tire as a backup in case of a flat tire, perfect for limited emergency use. However, it's necessary to remember that this type of spare, often called a "donut," should not be used for long distances or at high speeds because it is not designed for prolonged or regular usage. The RX350h most typically uses a T165/80D17 104M compact spare tire, yet the size might vary depending upon the model year. Thus, it is always advised to cross-verify the specifications in the vehicle's manual or consult a professional to ensure compatibility in case of a replacement need. This temporary spare tire is purposely smaller and lighter to save space and weight in the vehicle, which contributes to the vehicle's overall performance and fuel efficiency.
Lexus RX350h models manufactured from 2023 to 2025 have tires with overall diameter ranging from 30.1" to 30.3", 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 RX350h years and trims.
Listed below are compact spare tire sizes that can fit some Lexus RX350h vehicles based on acceptable tire diameter range of 29.2" to 31.2". Some RX350h models may require the use of a traditional full-size tire as a spare. To ensure safe temporary mobility in case of a road emergency, always refer to the vehicle owner's manual for the correct Lexus RX350h spare tire size designated by vehicle's manufacturer.
