BKT EARTHMAX SR 30 E-3/L-3 OTR Radial Tire

The BKT EARTHMAX SR 30 is a heavy-duty, all-steel radial OTR (off-the-road) tire engineered with a dual E-3/L-3 tread classification, purpose-built for wheel loaders and articulated dump trucks operating in the most demanding construction and mining environments. Backed by BKT's global OTR engineering expertise, the EARTHMAX SR 30 is a proven solution where toughness and long-term durability are non-negotiable.

At the core of this tire is an all-steel radial casing reinforced by a multi-layer steel belt package, delivering exceptional structural integrity under extreme loads. The rigid block tread pattern provides superior traction, stable ground contact, and lasting durability across compacted haul roads, rocky terrain, and abrasive job site surfaces. A special cut-resistant tread compound defends against chips, cuts, and punctures — making the EARTHMAX SR 30 well-suited for the harshest OTR operating conditions.
