Underinflation is quietly draining your fuel budget and pushing CSA scores in the wrong direction. Revvo tackles both.
For most commercial vehicle fleets, fuel is the #1 operating cost. Aside from labor, tires usually come in as the #2 cost. But here’s the part that often gets overlooked: those fuel and tire costs are deeply connected. Not because of routing inefficiencies or driver behavior, but because tires are running underinflated. And the same issue that’s eating into your fuel budget? It’s also pushing your CSA scores higher.
Across North America, millions of gallons of fuel are burned unnecessarily each year. This is where Revvo comes in, with AI-powered tire management that has a meaningful impact. Facing cost pressure, fleets are asking what they actually gain from the recent influx of vehicle and tire data. Revvo’s unique value is that it gives proven, measurable impact, both financially and operationally.
The Industry Baseline: Underinflation Is Pervasive
Let’s start with data. Research from NACFE and TMC shows that only 46% of tractor tires are within ±5 PSI of their target inflation level. The data for trailer tires is worse, with only 38% meeting their target inflation threshold. About 20% of trucks and trailers have at least one tire underinflated by 20+ PSI. What’s most worrisome is that at least 3% of vehicles are running with dangerously severe underinflation (50+ PSI). This is systemic, not edge-case, behavior.
Revvo Fleet Data: Severe Underinflation and Pressure Variation Prior To Deployment
To validate the industry findings, we analyzed partner fleets that were comparable to the industry baseline study. After analyzing 98 million miles, we found that vehicles prior to deploying Revvo had an average variation of pressure of 8 PSI. This is in line with the study results and equates to a 1.2% fuel loss using the same formulas as the study. For our fleets over this time period, that’s equivalent to $922,000 lost at the national average diesel fuel price of $5.635 per gallon.
For our fleets, just inflating by 8 PSI will save them almost $1 million dollars in fuel loss.
CSA Impact: The Overlooked Multiplier
Here’s what most fleets miss: The same tire issue causing fuel waste is also driving CSA violations. Pre-Revvo, fleets cluster in the 80th–95th percentile. Reminder: a higher percentile = worse CSA score. And appearing in the 80+ percentile means a higher risk of getting flagged by the DOT. This matters because tire violations are one of the most common causes of Out-of-Service (OOS) events. Each violation means:
- Lost revenue
- Delayed deliveries
- Increased insurance exposure
- Compounding CSA score damage
As noted by Midwest Sanitation’s Site Manager, “The impact was immediate. We started seeing improvements in uptime and cost within weeks.”
Before vs After Revvo: What The Data Shows
Before Revvo, vehicle fleets had high underinflation rates, between 1 and 4% loss in fuel efficiency, their CSA percentiles frequently topped 80%, and they had reactive maintenance cycles.
After Revvo, fleets gained continuous tire visibility (24/7/365) and a significant reduction in underinflation ratio. Fleets moved away from the “flagged” risk zone, and we saw sustained improvement (to more than 30% over the industry average).
After Revvo, fleets recovered meaningful fuel efficiency (~1%+ at scale) and their CSA percentile trended downward toward better safety compliance. For example, an oil and gas fleet had a BASIC percentile of 71 three months prior to deploying with Revvo, dangerously close to being flagged by the DOT. After 9 months of using Revvo, the fleet has dropped to the 50th percentile, remaining safely under the DOT flag of the 80th percentile.
Revvo brought these fleets predictive, not reactive, tire management operations. Revvo’s TireIQTM AI intelligence engine delivers custom dashboards and proactive alerts for real-time recommendations and reports. “We know there is a tire issue before it happens. I’m able to go through the reports, and the alerts have actually been generated before I manually send a message,” said the City of North Las Vegas.
The Bigger Picture: AI As The Operating System For Tires
At Revvo we think about this as more than tire pressure alerts. We consider AI optimization for timing, automation, and scale. Without AI, fleets rely on periodic inspections and issues go undetected for days or weeks. Worse, fuel loss and CSA risk compound silently.
With Revvo, every tire is monitored continuously and each anomaly is detected in real time. What’s more, every decision happens at the optimal moment. Why is Revvo intelligence better? Revvo isn’t limited to dashboards or reports. Built on years of real-world data, deep compute investment, and specialized machine learning expertise, Revvo delivers advanced fleet intelligence others can’t replicate. Across 98 million miles, Revvo-driven improvements delivered:
- ~163,000+ gallons saved
- ~$922,000+ in fuel cost reduction
- Measurable CSA score improvement
- Reduced risk of OOS violations
And that’s before factoring in extended tire life, fewer roadside failures, and lower maintenance cost. Fuel efficiency and CSA performance often are treated as separate problems. But they’re both symptoms of the same underlying issue: lack of real-time tire intelligence. As the AI operating system for every tire in your fleet, Revvo fixes both fuel inefficiency and CSA risks.
