Every driver in the USA and Canada knows the routine. Load up, pull out, and detour to the nearest CAT scale to find out whether the tractor and trailer are legal. Pay around 13 to 15 dollars for the first weigh, a few dollars more for a reweigh, wait in line behind three other trucks doing exactly the same thing, and hope the ticket comes back clean. If the drive axles are over, you slide the fifth wheel or the tandems, get back in line, and pay again.
An air ride scale ends that routine. If your tractor unit rides on air ride suspension, the weighing hardware is already under you. AirRide Scale adds wireless RF sensors to each air bag group, and the pressure in your suspension becomes a live, accurate weight on your phone.
What an air ride scale does for a tractor unit
On a typical US tractor, two numbers rule your day: the steer axle, usually limited to 12,000 pounds, and the drive tandem, limited to 34,000 pounds under federal rules. Slide a load too far forward and the drives go heavy; too much weight on the nose and the steer is over. An air ride scale reads both groups continuously, so you see the split while the trailer is still at the dock.
- Steer axle live weight, watched in real time as the load goes on.
- Drive axle group live weight, the number that catches most drivers at the scale house.
- Gross combination weight, so you know where you sit against the 80,000 pound federal limit.
- Legal limit status, a clear compliant or over reading in the Loadsense app on iOS and Android.
The real cost of weighing at the CAT scale
The ticket price is only the start. A team running five loads a week can spend well over a thousand dollars a year on scale tickets alone. Add the detour miles, the fuel, and the 20 to 40 minutes a busy truck stop scale can absorb, and public scales quietly become one of the most expensive habits in trucking. Worse, they only tell you the answer after the trailer doors are shut and the truck is loaded. If the ticket is bad, the fix costs you another weigh.
The comparison that matters: a public scale tells you your weight once, for a fee, after loading. An air ride scale tells you your weight all day, for free, while loading. Most operators find the system pays for itself within the first season of avoided tickets, reweighs and fines.
Fits the tractors you already run
AirRide Scale is a fast aftermarket retrofit for tractor units with air ride suspension on the drive group. Sensors mount at each air bag position, the AirRide Air Link hub gathers the RF signals and relays them by Bluetooth to your phone, and calibration takes a few minutes against a known weight, your last clean scale ticket works perfectly. There is no in cab display to wire and no cables run through the frame. Pair the tractor with sensors on an air ride trailer and the whole combination reads on one screen. See the full setup on our onboard truck scales page.
Air ride suspension only. AirRide Scale weighs through the air springs, so it fits tractors and trailers with air bag (air ride) suspension on each axle group you want to weigh. Spring ride axles are not supported.
Built for US and Canadian operations
Weights display in pounds or kilograms, which matters when you run cross border and the roadside numbers switch from a 34,000 pound tandem to provincial limits in kilograms. Calibrations are stored on your device, and the optional Loadsense cloud portal gives dispatch live visibility of every tractor in the fleet.
Day cabs, sleepers and LTL city work
The value is not limited to long haul. Day cab tractors on grocery and LTL city work hook to a different trailer several times a shift, and every hook changes the weight picture. Because AirRide calibrations live with each vehicle, a sensored tractor reads its steer and drives correctly under any trailer, and a sensored trailer brings its own group weight to any tractor. Owner operators who slip seat between tractors keep the app on their own phone, pair on arrival, and see live weights in seconds. For fleets, the optional Loadsense cloud portal shows dispatch every tractor’s weights in real time, so an overloaded unit gets caught in the yard, not on the interstate. And when a shipper insists on loading heavy, the app screen gives the driver something a gut feeling never could: a number to point at while refusing the extra pallets, time stamped and defensible.
The bottom line: your tractor already holds the answer in its air bags. An air ride scale simply reads it out. Weigh every load, skip the line, keep the 15 dollars, and cross the scale house knowing the ticket would be clean. Ask us about fitting AirRide Scale to your tractor.
