Oliver Rubber offers the ULP Trailer (Ultra Low Profile), a U.S. Environmental Protection Agency (EPA) SmartWay-verified retread for wide base single tires. The tire can be used on long haul, wide base trailer applications and delivers enhanced fuel efficiency, providing fleets significant value and performance, according to the manufacturer. The tire includes a company-exclusive visual depth indicator (VDi Plus) that reduces the retention of foreign objects in the tread face. This not only allows for easy visual tread depth gauging, but also the reduced lodging of foreign material abates stone drilling conditions and casing penetration issues that typically occur in the trucking industry.
