Lexus RC 300 Spare Tire Sizes

The Lexus RC 300 has used a 5x114mm (5 x 4.5") bolt pattern for all models from 2016 to 2023 along with tire diameters ranging from 26.3" to 26.4" tall. Using a temporary spare tire with a diameter close to the standard tire has many benefits, especially for modern vehicles with larger brake calipers and anti-lock brakes or traction control systems. Tire diameter as well as wheel diameter clearance have been taken into account for the specific Lexus RC 300 years and options. In this case, 165/70R17 and 145/60R20 spare tire sizes are used to avoid vehicle components while closely matching the original tire size diameters.
