Lexus IS350 Spare Tire

The Lexus IS350 typically comes with a compact, temporary spare tire, also known as a "donut" tire, to use in case of a flat. This spare is designed to get you to a service station and not intended for long-term or high-speed use. The size of this spare tire can vary based on the Lexus IS350 model year, but many are equipped with a T145/70D18 tire. This is a smaller and lighter tire compared to the standard ones, helping to save space and weight in the vehicle. However, Lexus provides a tire inflation kit instead of a spare tire in some models or trims, necessitating the use of roadside assistance or a tire repair service if a flat occurs. Always check your specific vehicle's user manual or consult your dealership to verify the type and size of your spare tire.

Lexus IS350 models manufactured from 2006 to 2025 have tires with overall diameter ranging from 24.9" to 26.4", 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 IS350 years and trims.

Listed below are compact spare tire sizes that can fit some Lexus IS350 vehicles based on acceptable tire diameter range of 24.2" to 27.2". Some IS350 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 IS350 spare tire size designated by vehicle's manufacturer.
