Hercules Tires has launched the TIS RT1 by Hercules, a rugged terrain tire designed to bridge the gap between all-terrain and mud-terrain performance. Engineered for light trucks, SUVs, and crossovers, Hercules said the new tire delivers superior off-road capability without sacrificing on-road comfort.

Developed Through Collaboration 

The TIS RT1, a collaboration between Hercules Tires and TIS Offroad, is designed to meet the demands of adventure enthusiasts who need a tire that performs just as well on rocky trails as it does on paved highways.

“This is our third collaboration with Hercules Tires, and we’re extremely excited about what this product has to offer. We designed this tire for drivers who demand both style and capability, whether they're pushing limits off-road or turning heads on the street,” said Myles Kovacs, TIS president and founder. “Partnering with Hercules Tires allows us to bring an aggressive, high-performance, rugged terrain tire to the market that complements our off-road wheel lineup perfectly."

TIS RT1 Key Features & Warranty

Backed by the Hercules Performance Promise warranty and boasting an industry-leading 55,000-mile warranty, the TIS RT1 features:

  • Hybrid rugged terrain capability - Engineered for the perfect balance of mud-terrain durability and all-terrain versatility. 

  • Quiet comfort - Optimized tread and siping absorb vibrations and reduce noise for a smooth, quiet ride on any terrain.

  • Dual-buttress design and bolstered sidewalls - Enhance durability and allow for a customized look.

  • Claw-like traction - Scalloped shoulder lugs and open shoulder grooves deliver powerful traction and expel mud quickly.

“The TIS RT1 by Hercules is a game-changer, expanding our product lineup to deliver even greater versatility and profitability for our customers,” said Steven Liu, vice president of product development at American Tire Distributors. “To showcase its capabilities, we invited select Hercules Tires dealers to the rugged trails of Moab, Utah, for an exclusive preview. Their feedback was outstanding, highlighting both the tire’s impressive performance and its competitive price point.”

TIS RT1 Available in 41 Sizes

After the phased launch, the TIS RT1 by Hercules will be available in 41 sizes, ranging from 16-inch to 22-inch rim diameters to accommodate a wide variety of vehicles, including the Ford F-150, Jeep Wrangler, Toyota Tacoma, and Chevrolet Silverado.
