American Tire Distributors (ATD) says the first Ironman brand all-weather highway terrain tire, the All Country HT 4S, is designed to deliver year-round confidence.

“The All Country HT 4S brings all-weather confidence to the highway terrain segment,” says Keith Calcagno, chief strategy officer, proprietary brands, ATD.

As Ironman’s first all-weather highway terrain tire, the All Country HT 4S is engineered for daily driving and long-distance comfort, expanding on the popular Ironman All Country lineup. It’s a highway-focused tire that combines advanced tread design, next-generation compound technology and all-weather capability with 3-Peak Mountain Snowflake (3PMS) certification.

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.

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. 

The All Country HT 4S comes in 46 sizes, with the first 27 sizes available now at Ironman retailers. It’s 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.
