Heat from any source is transferred to the tire causing deterioration of the bead. Normally, the burned bead causes loss of air, and the tire goes flat without hazard to anyone in the vicinity.Bead burning can result in the release of an explosive gaseous mixture inside the tire, which in some cases can ignite. The internal burning causes a rapid increase in pressure, resulting in a violent tire explosion. The explosion produces a blowout at the tire bead which reacts against the machine to propel the tire, rim assembly and final drive components a considerable distance from the machine.The danger of a tire explosion is greatest after the machine stops, because of the loss of the cooling effect of the circulating air due to wheel rotation.If smoke, excessive heat, the smell of burning rubber or hot brakes or other indications of bead burning are noticed, take action to prevent personal injury.Move the machine to a remote area, but only if it can be done without endangering the operator or other personnel in the area.Remove all personnel from the area where the machine is located.
Do not approach a tire closer than the outside of the area represented by the shaded area in the illustration.
If it is absolutely necessary to approach a machine with a suspected tire, do not get closer to the tires than 15 m (50 ft) at the front or rear of the machine nor closer to the side of the tire than 500 m (1500 ft).Do not approach any tire on the machine if there is a brake fire, burning rubber or other indications that excessive heat was generated by the brakes. Brake-generated heat probably affects all other tires on the machine, even though the visual evidence is only at one tire.If there is evidence of a brake fire or the smell of burning rubber, do not go near the machine. Stay away from the machine until the tires cool. Allow at least eight hours for the tires to cool before approaching the machine.Keep observers out of the area, and at least 15 m (50 ft) away from the front or rear of the machine and 500 m (1500 ft) away from the side of the tire. See the illustration.There is no absolutely safe approach when fighting a machine fire. Approach only at the front or the rear of the machine and use a large dozer as a shield.
Servicing and changing tires and rims can be dangerous and should be done only by trained personnel using proper tools and procedures. If correct procedures are not followed while servicing tires and rims, the assemblies could burst with explosive force and cause serious personal injury or death. Follow carefully the specific information provided by your tire or rim servicing man or dealer.
When tires are changed, be sure to clean all rim parts and, if necessary, repaint to stop effects of corrosion. Sand blasting is recommended for removal of rust. Check all components carefully. Replace any cracked, badly worn,
