Lexus RX450h Spare Tire

The Lexus RX450h, a luxury hybrid SUV, comes with a compact, temporary spare tire that is designed to get you to a service center rather than for prolonged use. This spare, often referred to as a 'donut,' is typically smaller than the standard size tires on the vehicle. The RX450h uses a T165/80D17 size spare tire, but it's essential to verify this information with the vehicle owner's manual or a Lexus dealership to ensure accuracy. Also, keep in mind that the spare tire's smaller size and reduced durability mean it should only be used for short distances at lower speeds.

Lexus RX450h models manufactured from 2010 to 2022 have tires with overall diameter ranging from 29.1" to 30.2", 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 RX450h years and trims.

Listed below are compact spare tire sizes that can fit some Lexus RX450h vehicles based on acceptable tire diameter range of 28.2" to 31.1". Some RX450h 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 RX450h spare tire size designated by vehicle's manufacturer.
