The size on the placard inside the driver's door jamb is the one your car left the factory with. Match that, not this table, if they differ; a previous owner may have changed wheels.

Worth knowing about the 2025 IS

  • LED lighting. The low beam, high beam, fog light, daytime running, brake light, tail light, reverse light, license plate are sealed LED units with no user-replaceable bulb. A failure means replacing the assembly.
  • Bulbs. Cars with LED front turn signals have sealed units in place of the 7440NA bulb.
  • Spare. This vehicle carries a compact (temporary) spare.
  • Tire chains. The manual permits tire chains or cables, within limits on which tires and which wheels. Those limits are in the next note; read them before you fit anything. Search Amazon for tire chains →
  • Tires. Tire chains go on the rear tires only, and the manual says chains cannot be mounted on cars with different front and rear tire sizes.
  • Torque. Tighten lug nuts to 103 ft-lbs in a star pattern with a torque wrench, and re-check after the first 50 miles. This figure is from the owner's manual; an impact gun will overshoot it.
  • Wheels. The IS uses wheel bolts threaded into the hub instead of studs and nuts.
  • Dimensions. The IS 500 is 187.3 inches long.
  • Octane. Premium (91 octane) is required, not recommended; the manual says so.
