Bandag has a new tread offering, called BTL-SA — Bandag Trailer Linehaul-Spread Axle. Specifically engineered for spread- and multi-axle trailer applications, the tread features tough shoulders for tires that twist, scrape and scrub as lateral stress is created when trailers corner.
Bandag says that tires on the forward axle of larger spread axle trailers really take a beating. The shoulders on the BTL-SA design are said to resist scrub-induced belt separations caused by dragging the forward axle tires in tight turns or while maneuvering at crowded loading docks.
The new design has a 16/32-in. tread depth and is now available in 210, 220 and 230mm sizes.
