Lexus IS500 Spare Tire
The Lexus IS500, like many modern vehicles, does not come with a traditional spare tire, due to the emphasis on weight reduction and improved fuel economy. Instead, it uses a tire repair kit that serves as a temporary solution in the event of a tire puncture. However, if a Lexus IS500 user chooses to have a spare tire, the general recommendation is for it to be the same size as the existing tires on the vehicle to ensure compatibility and safety. The usual size for Lexus IS500 tires is 235/40R19 for the front and 265/35R19 for the rear. Hence, the spare tire (if opted for) should ideally be within this specification range.
Lexus IS500 models manufactured from 2022 to 2025 have tires with overall diameter of 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 IS500 years and trims.
Listed below are compact spare tire sizes that can fit some Lexus IS500 vehicles based on acceptable tire diameter range of 25.6" to 27.2". Some IS500 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 IS500 spare tire size designated by vehicle's manufacturer.
