2019 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.
2019 Lexus IS350 comes with 2 OEM tire size options. Select the original equipment the tire size installed on your vehicle to see all spare tires that have roughly the same tire diameter and can be used as a temporary replacement in the event of a flat tire. Remember that load carrying capacity of the spare tire must be the same or higher than the load carrying capacity of the original equipment tires in order to safely support the weight of your vehicle. Refer to vehicle owner's manual or contact Lexus dealership to confirm the correct 2019 Lexus IS350 spare tire size.
