Tires and Wheels<br />
Tire Replacement<br />
Front: replace front tires when less than 4/32 in. of tread<br />
depth remains. Check depth at three places equally spaced<br />
around the tire.<br />
Drive Axles or Trailers: replace tires on drive axles when<br />
less than 2/32 in. of tread depth remains in any major groove.<br />
Check depth at three places equally spaced around the tire.<br />
WARNING! Do not install regrooved or reinforcement-repaired<br />
tires on steering axles. They<br />
could fail unexpectedly and cause you to lose<br />
control of your vehicle resulting in an injury<br />
accident.<br />
WARNING! Do not replace original equipment<br />
tires with load ratings less than the original<br />
tires. Doing so could lead to unintentional overloading<br />
of the tire, which could cause a failure<br />
resulting in loss of vehicle control and an injury<br />
accident.<br />
Preventive Maintenance<br />
NOTE: To prolong the tires' life and make them<br />
safer, have their radial and lateral run-out checked at<br />
your <strong>Peterbilt</strong> Dealer. And of course have the tires<br />
balanced any time you change a tire.<br />
Matching Tires<br />
Be sure to buy matched tires for your vehicle, especially on<br />
the rear axles. Mismatched tires can cause stress between<br />
axles and cause the temperature of the axle lubricant to get<br />
too hot. Matched tires will help the driveline last longer and<br />
will give you better tire mileage.<br />
WARNING! Do not mismatch tires, it can be dangerous.<br />
Never mix tires of different design such<br />
as steel belted radials and bias ply tires, etc.<br />
Mixing tire types and sizes will adversely affect<br />
the road-holding ability of both types of tires and<br />
can lead to loss of vehicle control and serious<br />
personal injury.<br />
Make sure, too, that you use the right size tires on each<br />
wheel. Some trucks require different sizes on front and rear<br />
wheels. For safety, always use the recommended size and<br />
type of tires.<br />
