Hercules TIS RT1 265/65R18XL E/10PLY BSW Tire

Hercules TIS RT1 Product Description

This listing is for new Hercules TIS RT1 265/65R18XL E/10PLY BSW Tires. Manufacturer part number: 98799.

The TIS RT1 by Hercules is a rugged terrain tire co-developed with TIS Offroad, engineered to sit precisely between an all-terrain and a mud-terrain. Backed by an exceptional 55,000-mile limited treadwear warranty, it offers one of the strongest value propositions in the hybrid off-road category.

The engineering priority is highway refinement without sacrificing trail capability. Built with a heavy-duty 3-ply sidewall construction, the tire features chamfer-stepped tread blocks that add lateral stiffness to limit squirm during cornering and towing. Off the pavement, scalloped shoulder lugs, wide open voids, and integrated stone ejector ribs continuously shed thick mud, sand, and gravel to maintain traction and prevent stone drilling. Dual buttress sidewall designs—featuring aggressive TIS Offroad styling—provide both enhanced abrasion resistance against sharp rocks and a customizable aesthetic for lifted builds.

Warranty coverage is backed by the Hercules Performance Promise, which includes a Road Hazard Protection program (offering free replacement during the first 50% of tread life) and a 45-day trial period.

As with every rugged terrain tire, expect slightly more noise and a minor fuel economy penalty compared to a standard all-terrain tire. To keep the ride smooth, have the set road force balanced rather than spin balanced, and rotate every five thousand miles to prevent shoulder cupping.

Best-suited for: Ford F-150, Jeep Wrangler, Toyota Tacoma, Chevrolet Silverado 1500, Ram 1500, Toyota Tundra, GMC Sierra, Ford Bronco.
