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 2018 Legacy
- Connector. Both front blades use a j-hook connector. A blade of the right length with the wrong connector will not clip on, so check the connector before you buy.
- LED lighting. The fog light, daytime running, brake light, tail light are sealed LED units with no user-replaceable bulb. A failure means replacing the assembly.
- Bulbs. The H11 and HB3 codes are for halogen headlights; the LED headlights on Limited models are sealed units.
- Spare. This vehicle carries a compact (temporary) spare.
- Tire chains. The manual says not to fit tire chains on this vehicle; wheel-well clearance is too tight.
- Tires. The manual says tire chains cannot be used, and a non-chain SAE Class S traction device goes on the front wheels only if its maker recommends it, and the compact spare is a T155/70D17.
- Torque. Tighten lug nuts to 88.5 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.
- TPMS. New sensors on this car need a relearn (tool); they will not pair on their own by driving.
- Key fob. Match the FCC ID (HYQ14AHK) printed on the back of your fob when buying a replacement; the same car can use two fob designs in one year. A new fob still needs programming to the car.
- Key fob. Trims without push-button start use a key with a remote head that takes a CR1620.
