2025 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.
