2020 Lexus RC300 Spare Tire
The Lexus RC300, a luxury sports coupe, does not come standard with a conventional spare tire. Instead, it comes equipped with a tire service kit or a tire repair kit, which includes an air compressor and a can of sealant to temporarily fix and re-inflate a punctured tire. However, for drivers who prefer to have a spare tire, they may opt for a compact temporary spare tire or "donut" that can be purchased separately. The size varies depending on the car's specifications but commonly you can go for a T145/70D18 size spare tire for most RC300 models. This type of spare tire is only intended to be used temporarily until the original tire can be properly repaired or replaced. It's crucial to remember these tires are not meant for speeds exceeding 50 mph and should be switched out for a full-size tire as soon as possible.
2020 Lexus RC300 comes with 3 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 2020 Lexus RC300 spare tire size.
