Check the tires and tire pressures Ford F150

1. Periodic inspection of the tires may spare you the inconvenience of being stranded with a flat tire. It can also provide you with vital information regarding possible problems in the steering and suspension systems before major damage occurs.

Use a tire tread depth indicator to monitor tire wear — they are available at auto parts stores and service stations and cost very little

2.   The original tires on this vehicle are equipped with 1/2-inch wide bands that will appear when tread depth reaches 1/16-inch, at which point they can be considered worn out. Tread wear can be monitored with a simple, inexpensive device known as a tread depth indicator.





Cupping may be caused by:.

Loose, damaged or worn front suspension parts.



3.      Note any abnormal tread wear. Tread pattern irregularities such as cupping, flat spots and more wear on one side than the other are indications of front end alignment and/or balance problems. If any of these conditions are noted, take the vehicle to a tire shop or service station to correct the problem.

If a tire loses air on a steady basis, check the valve stem core first to make sure it’s snug (special inexpensive wrenches are commonly available at auto parts stores)

If the valve stem core is tight, raise the corner of the vehicle with the low tire and spray a soapy water solution onto the tread as the tire is turned slowly — leaks will cause small bubbles to appear

4. Look closely for cuts, punctures and embedded nails or tacks. Sometimes a tire will hold air pressure for a short time or leak down very slowly after a nail has embedded itself in the tread. If a slow leak persists, check the valve stem core to make sure it is tight. Examine the tread for an object that may have embedded itself in the tire or for a «plug» that may have begun to leak (radial tire punctures are repaired with a plug that is installed in a puncture). If a puncture is suspected, it can be easily verified by spraying a solution of soapy water onto the puncture area. The soapy solution will bubble if there is a leak. Unless the puncture is unusually large, a tire shop or service station can usually repair the tire.

5. Carefully inspect the inner sidewall of each tire for evidence of brake fluid leakage. If you see any, inspect the brakes immediately.

6. Correct air pressure adds miles to the life span of the tires, improves mileage and enhances overall ride quality. Tire pressure cannot be accurately estimated by looking at a tire, especially if it’s a radial. A tire pressure gauge is essential. Keep an accurate gauge in the glove compartment. The pressure gauges attached to the nozzles of air hoses at gas stations are often inaccurate.

7.   Always check tire pressure when the tires are cold. Cold, in this case, means the vehicle has not been driven over a mile in the three hours preceding a tire pressure check. A pressure rise of four to eight pounds is not uncommon once the tires are warm.

To extend the life of the tires,check the air pressure at least once a week with an accurate gauge (don’t forget the spare!)

8. Unscrew the valve cap protruding from the wheel or hubcap and push the gauge firmly onto the valve stem. Note the reading on the gauge and compare the figure to the recommended tire pressure shown on the tire placard on the driver’s side door. Be sure to reinstall the valve cap to keep dirt and moisture out of the valve stem mechanism. Check all four tires and, if necessary, add enough air to bring them up to the recommended pressure.

9. Don’t forget to keep the spare tire inflated to the specified pressure (refer to the pressure molded into the tire sidewall).
