BKT Earthmax SR 33 Industrial Radial OTR Tire for Multipurpose Trucks

The BKT Earthmax SR 33 is a heavy-duty, all-steel radial OTR (off-the-road) tire purpose-built for multipurpose trucks operating in the most demanding off-highway environments. Engineered by Balkrishna Industries (BKT) — a globally recognized leader in off-highway tire manufacturing — the Earthmax SR 33 delivers the durability, traction, and dependability that construction, mining, and industrial operations require.

Key Features:

• Multi-Block Tread Pattern: Specially engineered block design provides extraordinary traction on soft, sandy, and muddy surfaces, while also performing reliably on mixed and hard-packed terrain — including ice and snow
• Superior Self-Cleaning: Open tread architecture continuously expels mud, sand, and debris to maintain consistent grip and prevent buildup in the most challenging underfoot conditions
• All-Steel Radial Casing: Full steel construction throughout the casing and belts delivers exceptional load-carrying capacity, long-term structural integrity, and outstanding resistance to snags and punctures
• Outstanding Stability: Radial construction and optimized footprint geometry provide a stable, predictable ride under continuous heavy loads across varied work site terrain
• Extended Service Life: The combination of a robust tread compound, steel reinforcement, and self-cleaning tread design supports reduced downtime and consistent productivity throughout the tire's operational life
• Broad Application Range: Purpose-built for multipurpose trucks in construction, mining, and industrial applications where versatile off-highway performance is essential
