Galaxy LDSR 300 All-Steel Radial OTR Tire - E-3/L-3

The Galaxy LDSR 300 is a premium all-steel radial off-the-road (OTR) tire line purpose-built for wheel loaders, dozers, and articulated dump trucks operating in the most demanding industrial environments. Rated to the E-3/L-3 tread designation, this tire series is engineered for both general and heavy-duty duty cycles across construction, quarry, mining, and severe-duty applications — delivering the stability, traction, and service life required for continuous high-productivity operation.

All-Steel Radial Construction

• Full all-steel radial architecture provides superior carcass strength, better ride handling, and improved fuel efficiency compared to bias-ply alternatives, while reducing heat buildup for extended service life
• Steel belt package delivers higher strength and enhanced puncture protection, with an optimized belt design that reduces stress concentration at belt edges and improves overall durability
• Flexible radial sidewalls create a larger, more even footprint — putting more tread in contact with the ground to transfer more horsepower, improve traction, and promote more even tread wear
• Reinforced sidewall protectors provide superior strength and endurance against the cuts, impacts, and abrasion common on demanding industrial worksites
• Premium damage-resistant tread compounds guard against lug-tearing, chunking, chipping, and cracking for maximized service life

Performance-Driven Tread Design

• Distinctive S-shaped tread pattern with innovative stepped lugs boosts traction by providing more biting surfaces on each lug across both soft and hard terrain
• Progressive stepped lug geometry causes lugs to widen as tread wears from step to step, increasing the rubber-to-void ratio and progressively slowing wear throughout the tire's full service life
• Optimized lug-to-void ratio supports superior traction alongside excellent self-cleaning performance, efficiently expelling debris to maximize machine uptime and productivity
• Wear and cut-resistant compound provides superior chipping and chunking resistance even in harsh quarry and construction environments

Proven Real-World Performance

• Field-tested globally in construction, quarry, and mining operations — demonstrating measurably longer service life compared to competing OTR tires in head-to-head evaluations
• Engineered to reduce total cost of ownership through a combination of long service life, consistent performance, and reduced machine stress from flexible sidewall construction
• Part of the Galaxy ROTR (Radial Off-The-Road) tire lineup, backed by Yokohama-ATG — a global leader in the design and manufacturing of commercial OTR tires
• Available in multiple sizes to fit a wide range of OTR equipment platforms and application requirements

The Galaxy LDSR 300 combines proven all-steel radial technology with industrial-grade materials and purpose-built tread engineering to deliver the stability, traction, and longevity required for efficient operation in the toughest working conditions. Whether on a construction site, in a quarry, or in heavy industrial service, this tire line is built to keep equipment running at peak productivity while helping to lower overall fleet operating costs.
