FireKing Hercules TIS RT1 285/55R20XL E/10PLY Light Truck & SUV Tire

The Hercules TIS RT1 is a rugged-terrain tire developed in partnership with TIS Offroad, combining aggressive styling with dependable off-road performance. Its bold tread blocks and wide voids provide traction on mud, gravel, and rocky terrain, while the self-cleaning design helps maintain grip in difficult conditions. Reinforced sidewalls not only enhance durability against cuts and abrasions but also add to the tire’s striking appearance. Despite its off-road focus, the TIS RT1 delivers stable handling and acceptable comfort on paved roads, making it versatile for everyday use. This tire is a strong match for lifted trucks and off-road builds where capability and appearance are equally important.
