The Key Variables in TBR Tires

What variables typically exist in looking for a medium/heavy truck tire?

Depending on the wheel position (steer, drive, trailer) there are a number of key elements to be expected:

STEER:

Due to the type of demands exercised on a steer axle, such as mass transfer during braking, cornering, etc., steer tires typically have these attributes:

  • 4 or 5 straight solid ribs that will support lateral forces created during normal handling, cornering and by wind drag.
  • Pattern design and compound resistant to irregular wear in long/medium haul service or cut and chip resistant for on-off service.
  • Tread depth balanced to deliver long tread life while delivering low rolling resistance for higher fuel efficiency.

DRIVE:

Depending on the type of operation, there are several options in tire design for a drive axle position: rib, mixed, lugs. Since in most cases high torque is required and weather conditions change from dry to wet to ice, the most common factors are:rlb400 cropped-1

  • Pattern design with closed shoulder (shoulder ribs) for long haul service to prevent irregular wear and provide good handling. The Double Coin RLB400 is a great example of an excellent performing closed shoulder drive tire with outstanding tread wear and traction.
  • Pattern design with open shoulder (shoulder lugs) for added traction capabilities. Double Coin recently introduced a new fuel-efficient open shoulder drive tire that offers biting edges across the tread to enhance grip and traction on Double Coin RLB452-1slippery road surfaces. The RLB452 is a great complement to the popular RLB1 open shoulder drive tire.
  • Deep tread for long tread life and low rolling resistance for fuel economy.

TRAILER:

Trailer tires have the slowest wear rate of all wheel positions because they: a) Do not steer the vehicle, b) Are not driven by the engine (no torque), c) Hold relatively light loads.

  • Shallow tread delivers longer life and low irregular wear.
  • Strong solid shoulders for strong dragging forces and scrub.
  • Special compound for low rolling resistance.

We encourage you to talk to your Double Coin dealer about the right tire specs. for your operation. Getting that right will go a long way toward reducing your tire operating costs!
