ST PRO+
The ST Pro+ Semi Steel ST is a durable highway terrain trailer tire built to deliver confident towing performance.
Its polyester casing with steel belts and nylon overlay enhances load carrying capability, while the ribbed tread and optimized shoulder design improve straight line stability, reduce sway, and promote long, even wear in a wide range of conditions.
The ST Pro+ All Steel ST offers all-steel sidewall and tread construction to handle heavy loads with strength and stability.
Its multi-sipe tread design improves grip on wet surfaces and promotes even wear by dispersing heat. Wide grooves enhance water evacuation, while a low-rolling-resistance tread compound boosts efficiency and extends service life.
