Vehicle Care

Note:If you overfill the tire, release airby pressing on the metal stem in thecenter of the valve. Then recheck thepressure with your tire gauge.
4. Replace the valve cap.
5. Repeat this procedure for each tire,including the spare.
Note:Some spare tires operate at ahigher inflation pressure than the othertires. For T type mini-spare tires, see theDissimilar Spare Wheel and TireAssembly section. Store and maintainat 60 psi (4.15 bar). For full-size anddissimilar spare tires, see the DissimilarSpare Wheel and Tire AssemblyInformation section. Store and maintainat the higher of the front and rearinflation pressure as shown on the Tire
Label.
6. Visually inspect the tires to make surethere are no nails or other objectsembedded that could poke a hole in thetire and cause an air leak.
7. Check the sidewalls to make surethere are no gouges, cuts or bulges.
Inspecting Your Tires and Wheel ValveStems
Periodically inspect the tire treads foruneven or excessive wear and removeobjects such as stones, nails or glassthat may be wedged in the treadgrooves. Check the tire and valve stemsfor holes, cracks, or cuts that may permitair leakage and repair or replace the tireand replace the valve stem. Inspect thetire sidewalls for cracking, cuts, bruisesand other signs of damage or excessivewear. If internal damage to the tire issuspected, have the tire demounted andinspected in case it needs to be repairedor replaced. For your safety, tires thatare damaged or show signs of excessivewear should not be used because theyare more likely to blow out or fail.
Improper or inadequate vehiclemaintenance can cause tires to wearabnormally. Inspect all your tires,including the spare, frequently, andreplace them if one or more of thefollowing conditions exist:
Tire Wear
When the tread is worn down to onesixteenth of an inch (2 millimeters), tiresmust be replaced to help prevent yourvehicle from skidding and hydroplaning.Built-in treadwear indicators, or wearbars, which look like narrow strips ofsmooth rubber across the tread willappear on the tire when the tread isworn down to one sixteenth of an inch(2 millimeters).
When the tire tread wears down to thesame height as these wear bars, the tire
is worn out and must be replaced.
