Lexus IS 250 Spare Tire Sizes

The Lexus IS 250 has used a 5x114mm (5 x 4.5") bolt pattern for all models from 2006 to 2015 along with tire diameters ranging from 25.0" to 26.0" 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 IS 250 years and options. In this case, 125/80R17 and 155/70R17 spare tire sizes are used to avoid vehicle components while closely matching the original tire size diameters.
