uu Checking and Maintaining Tires u Wear Indicators Wear Indicators Example of a Wear Indicator mark The groove where the wear indicator is located is 1/16 inch (1.6 mm) shallower than elsewhere on the tire. If the tread has worn so that the indicator is exposed, replace the tire. Worn out tires have poor traction on wet roads. 1 Checking Tires Models with P215/45R17 87V tires Models with 225/40R18 92V tires Models with 225/40R18 92Y tires High speed driving We recommend that you do not drive faster than the posted speed limits and conditions allow. If you drive at sustained high speeds (over 112 mph or 180 km/h), adjust the cold tire pressures as shown below to avoid excessive heat build up and sudden tire failure. Tire Size Pressure Tire Size Pressure P215/45R17 87V 35 psi (240 kPa, 2.4 kgf/cm2) 225/40R18 92V 225/40R18 92Y*1 36 psi (250 kPa, 2.5 kgf/cm2) Tire Service Life The life of your tires is dependent on many factors, including driving habits, road conditions, vehicle loading, inflation pressure, maintenance history, speed, and environmental conditions (even when the tires are not in use). In addition to regular inspections and inflation pressure maintenance, it is recommended that you have annual inspections performed once the tires reach five years old. All tires, including the spare, should be removed from service after 10 years from the date of manufacture, regardless of their condition or state of wear. *1: Optional for U.S. Si models (summer tires) 377 Maintenance
