Big truck tire sizes in our inventory vary by application, with common configurations including 12R22.5 (standard for 40-ton trucks), 13R22.5 (heavy haul), and 385/65R22.5 (wide-base single tires for fuel efficiency). Off-road models use 14.00R20 (14-ply rating) with deep treads (20mm) for traction, while low-bed trucks may feature 22.5-inch low-profile tires (aspect ratio 70) to reduce deck height. Tire load ratings range from 3,000 kg (single tire) to 5,000 kg (dual tires), with speed ratings up to 100 km/h. Contact our tire specialists for load index charts, recommended inflation pressures (8–12 bar), and tire life projections based on axle loads and road conditions.
