Tire Damage or Flat Tires Can Stem from Improper Air Pressure

When working around heavy machinery and their components you will need to take extra precautions. OTR tires are only used on large pieces of construction equipment and the tires alone can cause injury due to their weight. Once they are under pressure from the weight of the truck and its cargo they are even more dangerous.

The first thing that you will need to do is to remove the OTR tire from the vehicle. Before you start to loosen the lugs you should let out all the air from the tire or from both tires if it is in a dual assembly. If you were to try to remove the lugs while the tire is still under pressure and the wheel were damaged it could fly to pieces and injure you badly.

To make the deflation go as quickly and easily as possible you should remove the valve core altogether. Watch for ice forming in the valve or debris getting caught in it because it will shoot the material out at high speed. That is why it is a good idea to stand away from the tire as it is deflating and to wear eye protection as well.

Once the OTR tire is flat you will be ready to remove the rim components. Never try to do this by hand because the components are extremely heavy and can easily crush a foot or hand. Always use mechanical aids like jacks or dollies to help take the weight off of you and avoid injury.

When using the demounting tools always stand to one side. They are under great pressure when you are trying to unhook the beads and if it slips it can cause injury or even death. Make sure that you are standing out of harms way and that you are applying the force away from your body whenever possible.

Once you have separated the tire from the rim you should clean and repaint the rim. It will prevent deterioration over time. Also clean the lock ring to keep it free from dirt and grit. Inspect the rim for cracks and replace any of the components that you deem unsafe or weak. Make sure that the replacement parts that you use are free of wear and are of the correct type and size.

Before you mount the new OTR tire onto the rim you should inspect it also. Make sure that the tire, tube and flap are all in good condition and are free of cracks. Mount the tire onto the wheel and then double check the lock ring, o-ring and other parts to make sure they are all tightly sealed before inflation. If they check out then you can start to inflate the tire but stand away during the operation.
