The rim is the outer circular component of a wheel that holds and supports the tyre. It provides a secure connection to the tyre and is responsible for maintaining tyre shape and ensuring a proper seal with the tyre bead.

Rim offset is the distance between the centerline of the rim and the mounting surface that contacts the hub of the vehicle. It is typically measured in millimeters, and can be either positive, negative or zero.
  • Positive Offset: The mounting surface is closer to the front side of the rim’s centerline, common in factory wheels, bringing the tyre nearer to the vehicle’s body.
  • Negative Offset: The mounting surface is closer to the rear side of the rim’s centerline, pushing the tyre outward from the vehicle’s body.
  • Zero Offset: The mounting surface aligns precisely with the rim’s centerline, maintaining tyre alignment.

5 steps to measure rim offset:

  • Remove the wheel.
  • Find the rim centerline.
  • Measure rim width.
  • Measure backspace (the distance from the mounting surface to the inner edge of the rim)
  • Calculate offset: (Total width / 2) – Backspace.

OTR stands for “Off-The-Road” tyres. These are industrial tyres specifically designed for use on vehicles and equipment that operate in rugged off-road and industrial environments. OTR tyres are commonly used in mining, construction, agriculture, and other industries where standard tyres wouldn’t withstand the terrain and load demands.

OTR tyres come in various types, including Earthmover, Loader/Doser, Grader, Haul Truck, and Scraper tyres. Each type is designed for specific machinery and applications to provide optimal performance and durability.

OTR tyre size is typically represented as a series of numbers and letters. The Bias Ply or Rag indicates the tyre construction type, with “Bias Ply” referring to a specific method of layering the tyre plies. Here are some examples on how to read OTR Tyre size:

  • 26.5-25: A size designation for a large off-road tyre, with “26.5” being the tyre width in inches and “25” the rim diameter also in inches.
  • 35/65R33: Another tyre size, where “35 inches” is the tread width, “65%” of 35 inches is the sidewall height (aspect ratio), “R” stands for radial, and “33” is the rim diameter in inches.
  • 35X12.5R16: A common size for light trucks and SUVs, indicating a 35-inch tyre diameter, 12.5-inch tread width, radial construction (“R”), and a fit for 16-inch rims.

TBR stands for “Truck and Bus Radial”. TBR tyres are designed for heavy-duty trucks and buses. They have a different construction and tread pattern compared to passenger car tyres (PCR) to handle higher loads and longer distances.

The average lifespan of mining and earthmoving tyres depends on the truck classifications and their respective conditions. Typically, mining tyres can last anywhere from several months to a few years. Contact Tyre Doctor now to learn more about different types of mining and earthmoving tyres.

The cost of a mining tyre can vary significantly based on its size, type, brand, and specific application. Mining tyres are typically more expensive than standard tyres due to their durability and load-bearing capabilities. Let us know what you need and we will provide you with the best tyre solutions.

Yes, you can use secondhand tyres. However, it’s essential to consider their condition, tread depth, age, and any visible damage. At Tyre Doctor, safety is always the top priority when it comes to used tyres. Get in touch with us to find out the best solution for you!
