Triangle TR643 ST Radial ST225/75R-15

Designed for light trucks, the Triangle TR643 tire features a rounded profile for improved ride performance. Its sturdy construction ensures high load-bearing capacity as well as superb stability even at high speeds. The continuous center rib provides excellent grip while the high rubber density prolongs tread life. On wet surfaces, the grooves channel water from the footprint to increase ride safety while sipes provide excellent grip and reduce uneven wear.
