RL-4H / RL-4H II (E-4) The optimum footprint and load distribution of this 150-level radial rock tire are made possible by a flat tread design that gives it a long, even wear. A solid centerline section is ideal for high torque applications and provides a smooth ride. Impact resistance is provided by a high tensile steel belt package.

 

Features	Benefits
Solid centerline section	Ideal for high torque applications, longer wear and smooth ride
150-Level tread depth -- 50% deeper than standard E-3	Extra tread for long wear
Tire available in multiple tread compounds	Type 2 available for long high speed application, Type 3 available for intermittent high speed application, Type 4 available for standard haulage application and Type 6 available for abrasion resistance
Radial construction	Better fuel economy, softer ride and improved treadwear
