We all know that tires wear. There are certain things you, as an owner, can do to help minimize this wear.
Keep your tires properly inflated. This is perhaps the single most important thing you can do. Information on correct tire inflation pressure is provided in your owner's manual and on a placard on the driver's door pillar. How often you check your tire inflation is up to you. As a rule of thumb, tires should be checked every time you fill your car with gas. Remember that tires should be checked when cold since tire pressure will increase as the tires warm up.
Rotate your tires regularly. SUBARU recommends tires should be rotated every 7,500 miles. These are recommended intervals only. Your actual driving conditions may warrant more frequent rotation. Factors such as road surfaces, driving techniques/habits, vehicle loading, and weather, to name just a few, can all have an effect on tire wear.
Tire Replacement. The wheels and tires are important and integral parts of your vehicle's design; they cannot be changed arbitrarily. The tires fitted as standard equipment are optimally matched to the characteristics of the vehicle and were selected to give the best possible combination of running performance, ride comfort, and service life. It is essential for every tire to have a size and construction as well as a speed symbol and load index matching those shown on the tire placard. Using tires of a non-specified size detracts from controllability, ride comfort, braking performance and speedometer and odometer accuracy. It also creates incorrect body-to-tire clearances and inappropriately changes the vehicle's ground clearance. All four tires must be the same in terms of manufacturer, brand (tread pattern), construction, and size. You are advised to replace the tires with new ones that are identical to those fitted as standard equipment.
For safe vehicle operation, SUBARU recommends replacing all four tires at the same time. WARNING: All four tires must be the same in terms of manufacturer, brand (tread pattern), construction, degree of wear, speed symbol, load index and size. Mixing tires of different types, sizes or degrees of wear can result in damage to the vehicle's power train. Use of different types or sizes of tires can also dangerously reduce controllability and braking performance and can lead to an accident. Use only radial tires. Do not use radial tires together with belted bias tires and/or bias-ply tires. Doing so can dangerously reduce controllability which can result in an accident.
Temporary Spare Tire.
WARNING: Never tow a trailer when the temporary spare tire is used. The temporary spare tire is not designed to sustain the towing load. Use of the temporary spare tire when towing can result in failure of the spare tire and/or less stability of the vehicle and may lead to an accident.
CAUTION: Never use any temporary spare tire other than the original. Using other sizes may result in severe mechanical damage to the drive train of your vehicle. The temporary spare tire is smaller and lighter than a conventional tire and is designed for emergency use only. Remove the temporary spare tire and re-install the conventional tire as soon as possible because the spare tire is designed only for temporary use. Check the inflation pressure of the temporary spare tire periodically to keep the tire ready for use. The correct pressure is 60 psi (420 kPa, 4.2 kgf/cm2).
When using the temporary spare tire, note the following:
- Do not exceed 50 mph (80 km/h).
- Do not put a tire chain on the temporary spare tire. Because of the smaller tire size, a tire chain will not fit properly
- Do not use two or more temporary spare tires at the same time.
- Do not drive over obstacles. This tire has a smaller diameter, so road clearance is reduced.
1) Tread wear indicator bar. 2) Indicator location mark.
When the wear indicator appears on the tread, replace the tire.
NOTE: If your vehicle is an AWD type with an automatic transmission but is neither a Turbo model nor a 3.0 or 3.6-liter model, deactivate its all- wheel-drive capability as follows: Before driving your vehicle with the temporary spare tire, put a spare fuse inside the FWD connector located in the engine compartment and confirm that the AWD warning light comes on. The all wheel drive capability of the vehicle has now been deactivated. After re-installing the conventional tire, remove the spare fuse from the FWD connector in order to reactivate all wheel drive.
For more information on tires and temporary spare tire usage, always consult your Subaru Owner's Manual since the above information may vary slightly from model to model.
