The TIS TT1 by Hercules is a maximum-traction mud-terrain tire built in partnership with TIS Offroad, aimed at lifted trucks and Jeeps running flotation sizes on large-diameter wheels. It comes in load range E and F with a Q speed rating, which is standard for a tire of this construction.
The reinforced three-ply sidewall is the structural story. It is what lets you air down for trail traction and take sidewall impacts without failing, while a high-strength rubber compound actively resists cuts, chips, and abrasions from jagged rocks. Bolstered shoulder lugs and a wide void ratio clear mud instead of packing solid, aided by integrated stone ejector ramps that prevent debris buildup and protect the casing. Additionally, two distinct sidewall designs let you pick the look that matches the build. This tire is bought as much for stance and appearance as for capability, and there is nothing wrong with that as long as you know what you are getting.
Be realistic about the trade-offs, because they are the same for every tire in this category. While an optimized contact footprint helps improve straight-line tracking on the highway, a mud-terrain of this depth is loud and gets louder as it wears. It will cost you fuel economy against an all-terrain. It will not stop as short on wet pavement. And because these are heavy tires on large wheels, have them road force balanced rather than spin balanced, and re-torque your lug nuts after the first fifty to a hundred miles. Skipping those two steps is the most common cause of the vibration complaints people blame on the tire.
Best-suited for: Lifted Jeep Wrangler, Jeep Gladiator, Ford F-250, Chevrolet Silverado 2500, Ram 2500, Toyota Tundra, Ford Bronco, Ford F-150.
