Tires, Wheels and Loading WARNING: Stay out of the trajectory (1) as indicated in the illustration. TIRE CARE Inspecting your tires and wheel valve stems Periodically inspect the tire treads for uneven or excessive wear and remove objects such as stones, nails or glass that may be wedged in the tread grooves. Check the tire and valve stems for holes, cracks, or cuts that may permit air leakage and repair or replace the tire and replace the valve stem. Inspect the tire sidewalls for cracking, cuts, bruises and other signs of damage or excessive wear. If internal damage to the tire is suspected, have the tire demounted and inspected in case it needs to be repaired or replaced. For your safety, tires that are damaged or show signs of excessive wear should not be used because they are more likely to blow out or fail. 142 2010 Econoline (eco) Owners Guide, 3rd Printing USA (fus)
