11-30 Maintenance and service Wheel replacement When replacing wheels due, for example, to damage, make sure the replacement wheels match the specifications of the wheels that are fitted as standard equipment. Replacement wheels are available from SUBARU dealers. Aluminum wheels Aluminum wheels can be scratched and damaged easily. Handle them carefully to maintain their appearance, performance, and safety. There are 2 types of wheel nut wrenches that apply to different lengths. For an aluminum wheel vehicle, the 11.2-inch (285 mm) wheel nut wrench is equipped as a maintenance tool. And for a chrome plated wheel vehicle, the 13.2-inch (335 mm) wheel nut wrench is equipped as well. Always use a wheel nut wrench for an aluminum wheel. If you use a wrench for a chrome plated wheel, you cannot tighten it to the specified torque. When any of the wheels are removed and replaced for tire rotation or to change a flat tire, always check the tightness of the wheel nuts after driving approximately 600 miles (1,000 km). If any nut is loose, tighten it to the following specified torque. A tightening sequence specification for the wheel nuts can be found in the "Flat tires" in chapter 9. Use only those wheels that are specified for your vehicle. Wheels not meeting specifications could interfere with brake caliper operation and may cause the tires to rub against the wheel well housing during turns. The resulting loss of vehicle control could lead to an accident. 1 900292 1) The length of the wheel nut wrench
