04 09.01 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 185/55R15 or 215/45R16 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 185/55R15 or 215/45R16 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 inflation pressure is low, the tire may have a greater damage. For detailed information about tire inflation pressure, see page 244 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.). If you have tire damage such as cuts, splits, cracks deep enough to expose the fabric, or bulges indicating internal damage, the tire should be replaced. If a tire often goes flat or cannot be properly repaired due to the size or location of a cut or other damage, it should be replaced. If you are not sure, consult with your Toyota dealer. If air loss occurs while driving, do not continue driving. Driving even a short distance can damage a tire beyond repair. Any tires which are over 6 years old must be checked by a qualified technician even if damage is not obvious. Tires deteriorate with age even if they have never or seldom been used. 216 2005 MR2 from Aug. '04Prod. (OM17527U)
