The SH391 E-3/L-3 OTR tire is designed for CAT 988-992, Komatsu WA800-900, and Hitachi ZW550 wheel loaders used in mining operations across South America. Its horizontal tread pattern with wide tread construction provides excellent traction and wear resistance for loading copper ore in Chilean mines and iron ore in Brazilian operations.

The SH391 features a cut-resistant rubber compound combined with a horizontal tread pattern that helps deflect sharp debris. In steel mills across Brazil and Argentina, this design protects against cuts from scrap metal and slag. The wide tread construction also provides stability on uneven construction surfaces, making it suitable for demanding industrial applications.

The SH391 delivers competitive tread life in South American mining conditions, typically 3,000-4,500 hours depending on operating conditions. In copper mines (Chile, Peru), the cut-resistant compound preserves tread depth despite sharp ore. In iron ore operations (Brazil), the wide tread ensures even wear distribution. Regular tire rotation and proper inflation can extend tread life by 15-20%.

To order SH391 tires for delivery to Chile (San Antonio, Antofagasta ports) or Peru (Callao, Matarani ports), contact our export team. Standard sea freight takes 30-45 days from China. Volume discounts are available for mining operations ordering 20+ tires per shipment. We recommend maintaining a safety stock of 2-4 SH391 tires for critical mining equipment.

Yes, the SH391 is designed as a dual-purpose E-3/L-3 tire, making it versatile for both mining and construction applications. In E-3 mode, the horizontal tread pattern provides excellent traction on hard-packed surfaces common in mining. In L-3 mode, the wide tread delivers stability on loose rock and uneven terrain found in construction sites. This versatility makes it a cost-effective choice for mixed-use fleets.
