2025 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.
2025 Lexus IS500 comes with 1 OEM tire size option. 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 2025 Lexus IS500 spare tire size.
