Tips to Prolong Lighting Life (Cont.)
Look for loose, bare or unsupported wire, and fixtures. Harnesses and wiring should
be on the underside of the top frame members rather than on the bottom where dirt
and road splash collect.
You should never crank a truck when any lights or accessories are on. Also, never
leave markers and hazard lights on when parked against a dock. Melted lenses are
a sure sign that the vehicle has been parked against a dock while the lights were
Inspect the grommets that house the lamps. As they age, they eventually will
deteriorate from sunlight, ozone, and harmful chemicals. New grommets restore
shock protection, security, and improve appearance.
10 TIRE TIPS
The following information was developed from commercial analysis and is presented to give a
better understanding of the preventive maintenance.
A 15% under inflation of a tire can result in:
An 8% drop in tread wear (mileage)
A 2.5% drop in fuel mileage
Proper inflation drastically reduces tire blowouts.
On the average, a tire in good condition, properly sealed, just sitting in place, will
lose 2 psi (14 kPa) per month of air pressure.
4. Inflation pressure run just 10% under recommended tire pressure, can cause casing to
be unfit for re-treading.
Never use a bias ply and a radial tire on the same wheel position
Mismat ching causes:
The larger diameter tire to become overloaded
Loss of traction on smaller diameter tire
Tread or ply separation
Tire body breaks
Repair punctures from inside of tire.
Remove the tire before the tread depth reaches 2/32 in. (1.6 mm).
Inflated tires can have an internal pressure force of 40,000 lb (275,800 kPa).
After just 50100 miles (80160 km) of service on a new vehicle or new tires, re-
torque wheel nuts.
10. A tire cage is a must and could save a life.
