Triangle TB526S Buying Guide for Global Importers
Radial OTR tires such as the Triangle TB526S use a steel-belted casing. Compared with bias tires they run cooler, give a larger footprint and usually last longer on long hauls and at higher speeds, which lowers cost per hour. The difference between the two designs is explained in this overview of radial tire construction.
Choose the star rating (1-star, 2-star or 3-star) to match the load and inflation pressure your machine needs. For haul trucks, check the TKPH rating against your site cycle so the tire does not overheat in hot climates. Keep pressures at the recommended level and inspect for cuts weekly.
