General Guidelines for Replacing OTR Inner Tubes
Based on the above factors, here are some general guidelines for determining when to replace OTR inner tubes:
Visual Inspection
Regularly inspect the inner tubes for visible signs of damage. If you notice cuts, cracks, bulges, or excessive wear, it is a clear indication that the tube needs to be replaced. Even small cuts can expand over time and lead to air leakage or tube failure.
Air Leakage
If you find that the tire is losing air more quickly than normal, it could be a sign of a leak in the inner tube. You can use a soapy water solution to check for leaks. Apply the solution to the tube, and if there are bubbles forming, it means there is a leak. In most cases, a leaking inner tube should be replaced.
Mileage and Operating Hours
Although it is difficult to provide an exact mileage or operating hour limit for OTR inner tubes, as it depends on various factors, a general rule of thumb is to consider replacement after a certain amount of use. For vehicles operating in normal conditions, replacing the inner tubes every 10,000 - 15,000 miles or 2,000 - 3,000 operating hours may be appropriate. However, in harsh conditions, this interval may need to be reduced.
Age
As mentioned earlier, regardless of the usage, OTR inner tubes should be replaced every 3 - 5 years. This is to prevent failures due to natural aging of the rubber.
OTR tires can be found in three different construction types:
Bias OTR Tires: This type has cross-layered rubber plies, with cords crisscrossing from bead to bead across the tread. The overlapped plies create a thick structure that’s less flexible and able to hold more weight.
Belted Bias OTR Tires: Similar to bias OTR tires, this construction type tends to have two or more additional cross-ply layers with steel or corded stabilizing belts underneath the tread.
Radial OTR Tires: Like bias construction types, radial tires have cords that stretch from bead to bead across the tread. However, the cords run parallel instead of crisscrossing, resulting in a strong tire that is also very flexible.
OTR Tire Maintenance and Inspections
Our Inspections Include:
Air pressure checks
We check and adjust tire pressures to ensure they are at the recommended levels. Proper inflation is crucial for tire longevity, fuel efficiency, and safety.
Tire condition checks
We inspect the tires for signs of wear and damage, such as tread depth, cuts, punctures, bulges, or other irregularities. The goal is to identify and address potential issues before they become safety hazards.
Tread depth checks
We measure and record the tread depth of each tire to assess their remaining life and compliance with legal minimum tread depth requirements.
Replacement of worn or damaged tires
We identify tires that are no longer safe or suitable for use and recommend replacement.
Tire rotation
We evaluate whether your tires are rotated regularly to promote even wear and perform rotations if needed.
Tire age checks
We determine the age of your tires, as older tires may be more susceptible to issues like dry rot and decreased performance.
