Ironman Tires Launches All Country® HT 4S, the Brand’s First All-Weather Highway Terrain Tire
New Highway Tire Delivers Improved Ride Comfort, Wet Handling and Snow Traction
HUNTERSVILLE, NC — February 24, 2026 — Ironman Tires today announced the launch of the All Country® HT 4S, the brand’s first all-weather highway terrain tire designed to deliver year-round confidence, enhanced ride comfort and dependable traction for everyday drivers.
The All Country® HT 4S expands the popular All Country® lineup with a highway-focused tire that combines advanced tread design, next-generation compound technology and all-weather capability with Three-Peak Mountain Snowflake (3PMS) certification without compromising tread life or affordability. The All Country® HT 4S come in 46 sizes, with the first 27 sizes available now at Ironman retailers.
“The All Country® HT 4S brings all-weather confidence to the highway terrain segment,” said Keith Calcagno, Chief Strategy Officer, Proprietary Brands, American Tire Distributors. “These tires are designed for drivers who want a quiet, comfortable ride with dependable traction in rain and snow — all at a value they can trust.”
The All Country® HT 4S features an intricate tread pattern engineered through advanced modeling and simulation to enhance wet handling, braking performance and overall ride quality. A next-generation all-weather compound featuring a 600 UTQG treadwear rating delivers improved snow traction and 3PMS certification, providing added security in wintry conditions while maintaining long mileage performance.
As Ironman’s first all-weather highway terrain tire, the HT 4S is engineered for daily driving and long-distance comfort. Its optimized tread pattern and structural design improve steering response and wet traction, while a simulated pitch sequence and carefully engineered tread block arrangement reduce pattern noise and vibration.
Key features of the Ironman All Country® HT 4S include:
- All-weather tread compound with high-performance polymers that exceed 3PMS certification requirements while enhancing mileage performance
- Optimized tread pattern and tire construction to boost wet handling, braking and steering response
- Four wide circumferential grooves and 3D siping to promote excellent wet traction, braking and grip in snowy and icy conditions
- Enhanced ride comfort through simulated pitch design, optimized tread block arrangement and strategically designed groove angles to reduce noise at highway speeds
The Ironman All Country® HT 4S is backed by a 60-month limited protection policy covering defects in workmanship and materials, Road Hazard Protection and a 55,000-mile warranty, reinforcing Ironman’s commitment to reliability and value.
