2018 Lexus LC500h Spare Tire
The Lexus LC500h, like many vehicles today, does not come equipped with a spare tire due to efforts to reduce weight and improve fuel efficiency. Instead, it comes standard with a Tire Repair Kit, which includes an inflater and sealant that can temporarily patch a small puncture in the tire. However, if the vehicle is equipped with the optional 21-inch wheels, the LC500h does have a spare tire. The tire size for the LC500h is 245/45RF20 (front) and 275/40RF20 (rear). If owners prefer to have a spare tire, they can consider purchasing a smaller, temporary spare tire – often called a "donut" – that can fit in the trunk of their vehicle.
2018 Lexus LC500h 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 2018 Lexus LC500h spare tire size.
