Tyre management: 15% low pressure = 3% extra fuel
Tyre pressure is a famously invisible loss category. Drivers don’t check weekly, don’t notice, no manual report. Average EU fleet tyre pressure runs 15% low (Michelin Truck Tyre Study 2024) — that’s 3% extra fuel.
Industry case: A 100-truck fleet × 12,000 km/mo × 30 L/100 km × 3% extra = 1,080 L/mo extra fuel × €0.63/L = €680/mo = €8,000+/yr. Plus early wear → tyre life 80K → 60K km, extra €10K tyre cost.
TPMS + timestamped km tracking
Lognari tracks each tyre:
- Pressure (TPMS sensor)
- Temperature
- Installed km (cumulative)
- Depth (manual measurement)
- Lane history (frigo, ADR, mountain)
| Plate | Tyre # | Pressure | Temp | Km | Depth | Status |
|---|---|---|---|---|---|---|
| 34 LG 812 | F-L | 7.2 bar | 38°C | 78,000 | 6 mm | 🟢 OK |
| 34 LG 812 | F-R | 6.1 bar | 42°C | 78,000 | 5 mm | 🟡 Low |
| 34 LG 812 | R-1L | 8.4 bar | 35°C | 78,000 | 8 mm | 🟢 OK |
| 34 LG 815 | R-1L | 6.8 bar | 62°C | 95,000 | 2 mm | 🚩 Urgent |
When the threshold is breached: driver mobile alert + ops-centre dashboard.
Impact by fleet size
| Fleet | Annual fuel savings | Tyre-life extension | Total |
|---|---|---|---|
| 100 trucks | €8,000 | €10,000 | €18K/yr |
| 300 trucks | €24K | €30K | €54K/yr |
| 1,000 trucks | €80K | €100K | €180K/yr + CO₂ report |
Side effect: blowout prevention
Low pressure + high temperature = blowout risk. A single roadside blowout = €2,000–€5,000 (mobile service + trip cancellation + customer loss). Pilot fleets prevent 5–8 such cases per year.
What’s next
If your fleet doesn’t track TPMS data, 15% pressure deviation is likely there — concrete saving €8K–€18K/yr per 100 trucks.
