CATERPILLAR 130G MOTOR GRADERS

Technical Description

The 1982 Caterpillar 130G motor grader is equipped with 13.00-24 pneumatic bias-ply tires specifically engineered for demanding grading applications. These G-2/L-2 rated tires feature a robust 12-16 ply construction with an overall diameter of approximately 50.2-50.5 inches and a section width of 13.1-13.4 inches. The tires are rated for maximum loads of 6,000-7,150 lbs depending on ply rating, with a maximum air pressure of 44-58 PSI. Manufactured as tubeless designs, they incorporate a chip-and-wear resistant rubber compound and feature massive lugs with large center overlap geometry designed to resist buckling, tearing, and cracking. The open-shoulder tread pattern provides excellent self-cleaning traction, making them ideal for heavy dirt and mud conditions typical on job sites. Static loaded radius measures approximately 23 inches with a rolling circumference around 149 inches. These tires typically weigh 158-180 lbs each and mount on 8.0-9.0 inch rim widths. The Caterpillar 130G itself is a 135 hp motor grader with a 12-foot moldboard and standard operational weight of 31,540 lbs, making these heavy-duty grader tires essential for providing adequate traction and durability across varied terrain and demanding applications.
