Tires High Speed Driving We strongly recommend that you do not drive faster than the posted speed limits and conditions allow. If you ever drive in a sanctioned competitive event at sustained high speeds (over 99 mph or 160 km/h), be sure to adjust the cold tire pressures as shown below. If you do not, excessive heat can build up and cause sudden tire failure. U.S. Advance Package, Advance Package with Entertainment, and Canadian Elite Package models Tire Size P255/50R19 103H Cold Tire Pressure for High Speed Driving Front: 33 psi (230 kPa, 2.3 kgf/cm2) Rear: 36 psi (260 kPa, 2.6 kgf/cm2) Tire Inspection Every time you check inflation, you should also examine the tires for damage, foreign objects, and wear. You should look for: ● INDICATOR LOCATION MARKS Bumps or bulges in the tread or side of the tire. Replace the tire if you find either of these conditions. Cuts, splits, or cracks in the side of the tire. Replace the tire if you can see fabric or cord. Excessive tread wear. TREAD WEAR INDICATORS ● ● Your tires have wear indicators molded into the tread. When the tread wears down, you will see a 1/2 inch (12.7 mm) wide band across the tread. This shows there is less than 1/16 inch (1.6 mm) of tread left on the tire. A tire this worn gives very little traction on wet roads. You should replace the tire if you can see three or more tread wear indicators. 536 2011 MDX
