Lexus RX 400h Spare Tire Sizes

The Lexus RX 400h has used a 5x114mm (5 x 4.5") bolt pattern for all models from 2006 to 2008 along with tire diameters ranging from 28.2" to 28.5" 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 RX 400h years and options. In this case, 155/85R18 and 145/85R18 spare tire sizes are used to avoid vehicle components while closely matching the original tire size diameters.
