'03 MATRIX_U (L/O 0201) -Checking and replacing tires Tread wear indicator CHECKING YOUR TIRES Check the tire tread for the tread wear indicators. If the indicators show, replace the tires. 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 Low profile tire like P215/50ZR17 may have greater damage than usual tires to its tire wheel when receiving impact from the road surface. Therefore, pay attention to the followings. 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 272 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. The effectiveness of snow tires is lost if the tread wears down below 4 mm (0.16 in.). Check the tires regularly for damage such as cuts, splits and cracks. If any damage is found, consult with a technician and have the tire repaired or replaced. 248 2003 MY COROLLA MATRIX_U (OM12767U)
