<h3>About Truck System Technologies (TST)</h3><p><strong>Truck System Technologies</strong>, better known as TST, has been a pioneering force in tire pressure monitoring since its founding in 2007 in Cumming, Georgia. The brand's origins are rooted in a critical gap in roadway safety: when federal tire pressure monitoring regulations came into effect for passenger cars, recreational vehicles and specialty vehicles were left out entirely. TST stepped in to fill that void, engineering wireless TPMS solutions purpose-built for the vehicles that needed them most.</p><p>From motorhomes and fifth-wheel trailers to agricultural equipment, boat trailers, and commercial transport vehicles, TST has developed monitoring systems that go far beyond the typical car or SUV market. The company's mission has always been to make tire safety technology both effective and accessible — protecting drivers, reducing blowout risks, and even improving fuel economy through properly maintained tire pressures.</p><h3>Industry-Leading OEM Trust</h3><p>One of TST's most notable achievements is its status as a first-mover in OEM, factory-installed TPMS. TST set the standard as the industry's first OEM-installed TPMS solution at major manufacturers and is now featured on over 50 model lines. This factory-level endorsement speaks volumes about the engineering quality and reliability behind every TST product.</p><p>In 2017, Pressure Systems International (PSI) — a major player in automatic tire inflation for commercial trucking — acquired TST, bringing additional industry expertise and resources that further elevated TST's technology and customer support capabilities. Today, TST operates as part of Clarience Technologies and continues to be the go-to brand for RV owners, fleet operators, and outdoor enthusiasts who take tire safety seriously.</p><h3>TST's Core Product Lineup</h3><p>TST's catalog is laser-focused on tire pressure monitoring technology. Their flagship <a href="/11221-truck-system-technologies-tire-pressure-monitoring-system-kit-55374">Tire Pressure Monitoring System Kits</a> — including the popular 507 Series and 770 Series — come as complete, ready-to-install packages with a color display monitor, sensors, a signal repeater, and all necessary mounting hardware. These all-in-one kits are designed to monitor up to 115 tires across multiple vehicles simultaneously, making them ideal for RVers towing additional trailers or managing a small fleet.</p><p>For those who need to expand an existing system or replace a component, TST offers individual <a href="/11221-truck-system-technologies-tire-pressure-monitoring-system-sensor-12036">Tire Pressure Monitoring System Sensors</a> — available in both cap and flow-through configurations. Cap sensors thread directly onto any standard valve stem, while flow-through sensors allow tire inflation without removal, ideal for metal valve stem setups. All sensors feature waterproof construction, anti-theft design, and user-replaceable batteries for long-term reliability.</p><p>TST also offers <a href="/11221-truck-system-technologies-tire-pressure-monitoring-system-programmable-sensor-17647">Tire Pressure Monitoring System Programmable Sensors</a> for those needing more customizable integration, including internal wheel sensor options that trigger alarms when pressure or temperature deviates from user-set thresholds. Every TST system delivers real-time pressure and temperature data with clear audible and visual alerts — in plain, easy-to-understand language — so drivers always know exactly which tire needs attention.</p><h3>Why Choose TST?</h3><ul><li><strong>Proven OEM pedigree:</strong> Factory-installed on over 50 RV model lines by major manufacturers</li><li><strong>Comprehensive coverage:</strong> Systems capable of monitoring up to 115 tires across up to 4 trailers or towed vehicles</li><li><strong>Durable sensors:</strong> IP67-rated dust and water resistance for all-weather, real-world performance</li><li><strong>Expandable architecture:</strong> Add sensors and trailers as your rig grows, without replacing your display</li><li><strong>Three-year warranty:</strong> Backed by USA-based live customer support trusted by thousands of RV owners</li><li><strong>Broad vehicle compatibility:</strong> RVs, motorhomes, marine trailers, agricultural equipment, ATVs, and more</li></ul>
