UVALDE, Texas—Continental Tire the Americas L.L.C. has renewed its lineup of construction industry truck tires, launching new generation versions of its HSC and HDC steer and drive tires for the segment.
Continental focused on improving the tires' original tread life through new tread patterns, advances in tread compounding and re-engineered belt and bead packages, according to Libor Heger, head of brand management for commercial vehicle tires, the Americas, speaking to customers and the media at a presentation at Conti's 5,000-acre Uvalde Proving Grounds.
The construction sector represents about 15 percent of the annual demand for replacement market truck tires in the U.S., according to Clif Armstrong, director of marketing for CTA's commercial vehicles tires unit, but is extremely specialized with needs for off- as well as on-road traction, self-cleaning tread patterns, distinct sizes and sufficient load-carrying capacities.
The HDC1 (Heavy Drive Construction) features a one-inch tread depth, a heavy-duty compound, aggressive open shoulder design and a self-cleaning tread pattern with V-shaped grooves designed to reduce stone retention, which should result in few casing penetrations, Conti said.
The HSC1 (Heavy Steer Construction) features a three-groove tread designed to perform well even on loose surfaces along with offering self-cleaning properties.
Both tire lines feature four-ply belt packages, with the second and third belts reinforced to help prevent fatigue-related problems and provide a stable platform for improved traction, according to Roger Stansbie, Conti's director of truck tire engineering for the Americas.
Conti also has re-engineered the bead core to increase its chafer density to make it more tear resistant and to enhance the chafer angle for improved fit with the rim, he said.
Both tires use Continental's new on/off road compounding, which increases resistance to tread cuts, chips and chunks and reduces the depth of tread damage, Mr. Stansbie said.
The new tires—HSC1 steer tire, HDC1 drive and HTC1 trailer—will be priced at a premium to their predecessors, Mr. Armstrong said, although the company did not disclose prices or the extent of the premium.
The HSC1 steer and HDC1 drive tires will launch in two sizes, 11R22.5 and 11R24.5 for load range H, with 12R sizes for the HSC1 coming later this summer, Conti said.
Conti earlier upgraded the HTC trailer tire line and now offers a complete line of upgraded heavy-duty tires.
The HTC1 comes in three sizes and features a deeper tread, 24/32 inch, than its predecessor.
The new heavy-duty tires are in addition to the HSU2+ waste haul truck tire Conti unveiled in the first quarter with a promise of greater structural stability and enhanced product performance.
The HSU2+ features 26/32-inch tread depth, as well as 276 millimeters of tread width for greater stability. It is available in size 315/80R22.5, load range L, and comes with Conti's VA1 (visual alignment) technology that alerts fleet or truck owners when the tire should ideally be pulled for retreading.
Additionally, Conti said it plans to have ContiLifeCycle retreads in the new tread patterns available later this year.
All the tires are made at the company's plant in Mount Vernon, Ill.
