Lexus GS 430 Spare Tire Sizes

The Lexus GS 430 has used a 5x114mm (5 x 4.5") bolt pattern for all models from 2001 to 2007 along with tire diameters ranging from 25.3" to 25.7" 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 GS 430 years and options. In this case, 125/80R17 and 125/70R18 spare tire sizes are used to avoid vehicle components while closely matching the original tire size diameters.
