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.

Lexus LC500h models manufactured from 2018 to 2025 have tires with overall diameter of 28.7", 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 LC500h years and trims.

Listed below are compact spare tire sizes that can fit some Lexus LC500h vehicles based on acceptable tire diameter range of 27.8" to 29.6". Some LC500h 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 LC500h spare tire size designated by vehicle's manufacturer.
