Short answer: AirDown and TIREBOSS are both central tire inflation systems (CTIS): both let a driver air truck tires down for off-road traction and back up for the highway, and both keep up with nails in tires. AirDown is U.S.-made and costs $7,495, the same nationwide, while before the August 2026 tariffs, TIREBOSS systems typically ran $8,500 to $12,000 depending on region. AirDown also starts instantly on a 7-inch touchscreen (TIREBOSS takes about 2 minutes to boot on a 5-inch screen), uses SMC valves that don’t need a yearly rebuild, and sells parts that cost about 30% less, including parts that fit TIREBOSS systems.

TIREBOSS has been building tire pressure control systems out of Edmonton, Alberta, for about 30 years, and it earned its reputation. This page isn’t here to knock that history. It’s here to give fleet managers a straight, side-by-side look at what each system costs, how each one works day to day, and which one fits which kind of fleet, using only facts we can stand behind.

This page replaces our two earlier AirDown vs. TIREBOSS posts. If you want the spec-by-spec look at the in-cab controllers, see our deeper dive: CTIS Controller and Display Compared: AirUp vs TIREBOSS 2.

What Both Systems Do

It’s worth starting with what AirDown and TIREBOSS have in common, because it’s a lot. Both are central tire inflation systems, which means the driver changes tire pressure from the cab while the truck is running. Lower pressure puts more rubber on the ground, and that’s what gets a loaded truck through sand, mud, a soft job site or a wet right-of-way. Higher pressure is what the truck needs back on pavement.

Both systems air down, and both air back up. Both will keep up with nails in tires, so a slow leak doesn’t have to end the shift. If you’ve read a comparison claiming TIREBOSS can’t air up, that’s wrong. It can.

TIREBOSS also brings about 30 years of field history, and its current TIREBOSS 2 product lists features such as GPS speed monitoring, load-sensing autonomous control, a touch screen and control of 1 to 4 tire groups (tireboss.com/product). If your fleet already runs TIREBOSS and it’s working, that history counts for something.

So the real question isn’t whether one of these systems works. Both do. The question is what each one costs to buy, to run and to keep running.

Where AirDown and TIREBOSS Differ

Price: One Number vs. a Regional Range

AirDown costs $7,495. That’s the price in Florida, Texas, Washington state or anywhere else in the country. AirUp, our air-up-only system, costs $3,995, also the same nationwide.

TIREBOSS pricing has varied by region for the same system. Before the August 2026 tariffs, TIREBOSS systems typically ran $8,500 to $12,000 depending on region. For example, they ran about $8,500 on a Florida concrete truck and up to about $12,000 in Washington state. If you run trucks in more than one state, that meant the same system could carry a different price depending on where the truck was based. With AirDown, the budget number is the same everywhere.

Screen Size: 7 Inches vs. 5 Inches

AirDown uses a Grayhill 3D70 7-inch CANbus touchscreen that starts instantly. TIREBOSS uses a 5-inch screen. In a bouncing cab, with gloves on, the size of the screen and its touch targets make a real difference to how quickly a driver can read tire pressures and change settings.

Boot Time: Instant vs. About 2 Minutes

AirDown’s controller starts instantly. TIREBOSS takes about 2 minutes to boot. Two minutes sounds small until you multiply it across every start, every truck and every day. That’s two minutes of a driver waiting to see pressures before rolling out of the yard or off the job site.

Valve Maintenance: No Yearly Rebuild

TIREBOSS valves need rebuilding about once a year. AirDown uses SMC valves that don’t. Over the life of a fleet, a yearly rebuild adds up in parts, shop hours and time the truck isn’t working. (For more on the service side of CTIS, see What It Really Takes to Service a CTIS Wheel-End Valve.)

Parts Cost: About 30% Less

AirDown parts are about 30% cheaper than TIREBOSS parts. AirDown also sells parts that work on TIREBOSS systems, so a fleet that runs TIREBOSS today can buy replacement parts from us without changing systems. You can browse them in the AirDown parts shop.

Where It’s Made and Tariff Exposure

AirDown is built in the United States. TIREBOSS is a Canadian company based in Edmonton, Alberta. Since August 2026, certain Canadian-made goods face new 50% U.S. tariffs (Section 338), according to a Wiley trade alert. AirDown is built in the U.S., so its pricing and supply aren’t exposed to cross-border tariffs.

Which System Fits Which Fleet?

Different fleets need tire pressure control for different reasons. Here’s how the choice usually breaks down by industry.

Concrete and Ready-Mix Fleets

A loaded mixer has to get onto soft, unfinished job sites and then back onto the highway. That’s exactly what air down and air up are for: drop pressure for traction on the site, and bring it back up for the road. Florida concrete fleets run AirDown for this work. On price, the comparison is simple: about $8,500 (pre-tariff) for TIREBOSS on a Florida concrete truck vs. $7,495 for AirDown. Read more in How Improper Tire Pressure Is Costing Your Concrete Fleet.

Power and Utility Fleets

Utility trucks leave the pavement to reach poles, lines and substations across fields, sand and mud, often during storm response when every minute counts. Airing down from the cab gets them there without a tow, and airing up gets them back on the road. Major Florida utilities use AirDown. For crews who need to move right after a start, a controller that’s ready instantly instead of after about 2 minutes matters. More in our utility fleet tire pressure guide.

Waste Haulers, Roll-Off and Garbage Trucks

For waste fleets, the problem usually isn’t traction. It’s nails. Garbage trucks and roll-off trucks working landfills pick up nails and screws constantly. AirUp is our air-up-only system built for that job: it keeps tires inflated even with 20+ nails, so the truck can keep working. TIREBOSS also keeps up with nails in tires, so this is a real choice. The difference is that AirUp does the job for $3,995, the same nationwide, and it doesn’t pay for air-down capability a waste truck may never use. If your trucks also need to air down for traction, AirDown does both. See the AirUp system.

Agriculture

Farm trucks move between soft, muddy fields and paved roads, sometimes several times a day. That’s a natural fit for airing down in the field and airing back up for the road. TIREBOSS markets to agriculture too, and it’s a credible option. AirDown offers the same core function with one nationwide price, parts that cost about 30% less, and valves that don’t need a yearly rebuild. More in our agriculture tire pressure guide.

Switching From TIREBOSS, or Using AirDown Parts on TIREBOSS

You don’t have to replace a working TIREBOSS system to save money on it. AirDown sells parts that work on TIREBOSS systems, and our parts cost about 30% less. Examples in our shop include a TIREBOSS Rockwell drive axle manifold and a TB inflate/deflate solenoid. If you don’t see your part listed, call us with the TIREBOSS part number and we’ll tell you what we have.

When it’s time for new systems, or when yearly valve rebuilds and regional pricing start to add up, switching to AirDown gives you:

  • One price, $7,495, for every truck in every state
  • A Grayhill 3D70 7-inch CANbus touchscreen that starts instantly
  • SMC valves with no yearly rebuild
  • Parts that cost about 30% less
  • A U.S.-built system whose pricing and supply aren’t exposed to cross-border tariffs

Mixed fleets work too. You can run AirDown on new trucks while you keep older TIREBOSS trucks running on AirDown parts, and deal with one supplier for both. To talk through your trucks, contact us or call 877-623-8473.

The Bottom Line

TIREBOSS is a proven system with about 30 years behind it, and it does the core job: air down, air up and keep up with nails. AirDown does the same job for less and with lower upkeep: $7,495 anywhere in the U.S. vs. a typical $8,500 to $12,000 (pre-tariff) for TIREBOSS, a 7-inch touchscreen that starts instantly, SMC valves with no yearly rebuild, parts that cost about 30% less and a U.S.-built supply chain. For waste fleets that only need air up, AirUp does it for $3,995.

Is AirDown or TIREBOSS better?

Both are capable central tire inflation systems that air down, air up and keep up with nails in tires. AirDown costs less ($7,495 nationwide vs. a typical $8,500 to $12,000 for TIREBOSS, pre-tariff), starts instantly on a 7-inch touchscreen instead of booting for about 2 minutes on a 5-inch screen, and uses SMC valves that don’t need a yearly rebuild.
