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.
Lexus RC300 models manufactured from 2016 to 2025 have tires with overall diameter ranging from 26.3" to 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 RC300 years and trims.
Listed below are compact spare tire sizes that can fit some Lexus RC300 vehicles based on acceptable tire diameter range of 25.5" to 27.2". Some RC300 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 RC300 spare tire size designated by vehicle's manufacturer.
