'08 MATRIX_U (L/O 0706) Checking and replacing tires Tread wear indicator The tires on your Toyota have built−in tread wear indicators to help you know when the tires need replacement. When the tread depth wears to 1.6 mm (0.06 in.) or less, the indicators will appear. If you can see the indicators in two or more adjacent grooves, the tire should be replaced. The lower the tread, the higher the risk of skidding. Vehicles equipped with P215/50ZR17 tires: Your Toyota has been fitted with specially developed tires which provide exceptional dynamic performance under general road conditions. However your riding comfort may worsen a little and road noise may increase during driving. You may also notice that your tires will wear more rapidly and tire grip performance will be reduced on the snowy and/or icy roads when compared to standard tires. Be sure to have snow tires or tire chains on the snowy and/or icy roads and drive carefully with the speed appropriate for road conditions. NOTICE CHECKING YOUR TIRES Check the tire's tread for tread wear indicators. If the indicators show, replace the tires. The location of tread wear indicators is shown by the "TWI" or "∆ " marks, etc., molded on the sidewall of each tire. Low profile tire like P215/50ZR17 or P215/50R17 90H may have greater damage than usual tires to its tire wheel when receiving impact from the road surface. Therefore, pay attention to the following. z Be sure to use with proper tire pressure. If the tire pressure is low, the tire may have a greater damage. For detailed information about tire pressure, see page 308 in Section 8. z Avoid driving onto high, sharp−edged objects and other road hazards. Failure to do so can lead to severe tire damage. 283 2008 COROLLA MATRIX from Aug. '07 Prod. (OM12B26U)
