The PT125 comes standard with four front and five rear 190,5 mm x 381 mm, 14-ply tires. The front tire pairs each oscillate +/- 3°.
The Volvo PT125 is a nine-wheel pneumatic tire compactor typically utilized on hot mix asphalt and on chip-seal applications. The four front tires are staggered in position to provide overlap with the five rear tires, resulting in complete material coverage for consistent texture and appearance. Uniform compaction, even on irregular surfaces, is achieved using tire oscillation to maintain uniform tire contact pressure.
