Who We Are

We're the kind of people who care about you getting from point A to point B without a tire blowing out, a brake catching fire, or a wheel-end failure ruining your day, your trip, or your life.

What We Do

We engineered an intelligent trailer monitoring system, TWD combines smart axle monitoring + Tire Pressure Monitoring System (TPMS), proactively flagging trend data, showing slow leaks and even heat from a dragging brake, long before smoke or a wobble in the wheel. Significantly reducing downtime, maintenance costs, and transportation risk. With a simple installation process, TWD can easily be added to any trailer. Android and iOS compatible, TWD runs unobtrusively in the background so you can use your phone as normal, alerting you only when action is needed - providing peace of mind mile after mile.

Why does this matter to you?

Small problems become big emergencies at highway speeds. Trailer Watchdog sees the early warning signs you can’t—heat, pressure, and trends—so you can fix issues before they ruin your day.

The TWD Lineup

No matter what kind of trialer you have, we make it safer.

PREVENTABLE FAILURES

Wheel-end failures start with heat.

The data shows it clearly: 85% of blowouts are preventable, 48% of road calls are tire related, and only 44% of tires are properly inflated.

TrailerWatchdog monitors each axle’s temperature and tire data in real time, alerting you before a blowout, hub fire, or wheel-off.

KEEP COSTS LOW

Keep your trailer out of the shop.

If you're like us, you don't want any unexpected expenses.

Our boat trailer's back tire blowing out on a hot summer day in Florida - was not part of the plan. Not only did we lose out on an amazing boat trip but, we also had thousands of dollars in repairs to worry about.

That's why we created TWD. A single product engineered to proactively keep you, your trailer, and everything you're hauling safe.

SAFETY & SECURITY

A blowout can be devastating.

Injury. Damage. Liability. Death.
Things we don't think about when hooking up our trailer - but maybe we should...

We created the TWD product line becuase honestly, no one else cared enough to do it first.

We have the only product on the market that combines intillegent tire and axle monitoring using smart trend analysis to identify issues before they happen.
