Atturo ST300

The Atturo ST300 is designed specifically for trailer applications – from utility trailers and RVs to boat and horse trailers. It is not for drive or steering axles of trucks, but instead optimized to perform under the unique conditions trailers experience. This tire boasts a reinforced internal structure and high load ratings (including 10-ply, 12-ply, and even 14-ply sizes), meaning it can handle substantial weight and pressure. When you’re towing, heat is the enemy of tires – the ST300 uses a special heat-dissipating tread design and durable compound to minimize heat build-up, even on long highway trips, thereby reducing the risk of blowouts. The tread pattern itself is designed for stability and even wear: it often has solid center ribs or interconnected blocks that help the tire track straight (preventing trailer sway) and deliver consistent contact for better control. The shoulders are squared-off to enhance lateral stability, which is important when crosswinds hit or during cornering with a trailer. For wet conditions, circumferential grooves help channel water and maintain grip, so your trailer stays obedient behind you in the rain. The ST300 also resists weather cracking – an important factor since trailer tires often sit unused for periods of time; UV and ozone resistant compounds help prolong its life. When parked or stored, the robust construction handles the weight without flat-spotting as much. Safety is paramount: the ST300 gives you the peace of mind that your trailer tires can handle the journey, allowing you to focus on the road ahead. Always inflate to the recommended PSI when towing to get the full benefit of its load capacity and performance. With Atturo ST300 tires, you can tow heavy loads confidently, knowing your trailer is riding on rubber that’s purpose-built for the task.
