MAXAM Expands MS303 Scraper Tire Line for Heavy-Duty Earthmoving

MAXAM Tire has added the 40.5/75R39 size to its MS303 scraper tire lineup, designed for demanding earthmoving operations. The addition provides contractors and quarry operators with an option built for durability, traction and consistent performance across challenging terrain.

The MS303 40.5/75R39 is engineered to deliver stability and ride quality at higher transport speeds, featuring a robust casing structure paired with an aggressive E3 tread pattern. Reinforced shoulders and sidewalls provide resistance to cuts and impacts, while a high-strength bead design enhances durability and machine stability under maximum load. These features aim to provide dependable traction and handling for large scraper fleets operating in variable and high-impact environments.

“Contractors and quarry operators run on uptime. The new MS303 40.5/75R39 delivers traction, durability, superior ride quality and control they demand on the toughest jobs,” said Jimmy McDonnell, vice president of sales and marketing at MAXAM Tire. “Our customers can move more material with fewer interruptions and a lower total cost of operations.”

The new size complements MAXAM’s existing MS303 scraper portfolio, which includes 33.25R39 and 37.25R35 sizes, allowing fleets to standardize on a proven tire design. By expanding the lineup, MAXAM aims to provide options that maintain performance and longevity, supporting productivity for heavy-duty earthmoving applications such as construction, quarrying and large-scale material handling.
