A45G OBW & TPMS — KSA / Exact steps to stabilize fuel, cycle time, and tyre life for the Volvo A45G in Saudi conditions.

Why This Matters Right Now (and Why It’s Not “Nice to Have”) OBW + TPMS in Saudi Heat

Saudi projects are hot, long-cycle, and schedule-driven. Two A45Gs with the same unit price can deliver very different $/ton once they hit the site. The separating line is usually payload discipline and tyre temperature/pressure control. Volvo’s Haul Assist suite—especially On-Board Weighing (OBW) and Tyre Pressure Monitoring System (TPMS)—is purpose-built to solve those exact problems:

OBW (On-Board Weighing) gives the operator precise, real-time payload with external signalling for the loader—cutting underloading, overload peaks, and carry-back, which stabilizes fuel per ton and cycle time. (Volvo Construction Equipment)
TPMS shows tyre pressure & temperature in the cab so the team can keep tyres inside their working window—crucial for Saudi summers where under-inflation drives heat and rolling resistance. (Volvo Construction Equipment)

Add this to the A45G’s baseline: ~45 short-ton payload (~41 t), ~469 hp (Volvo D16J), ~32.8 yd³ heaped body, ~35.4 mph (57 km/h)—and the machine has all the headroom. You just have to run it right. (Volvo Construction Equipment)

New to the model? See Volvo A45G Specs & Performance (2025) and [A45G FS] if you run rough/temporary roads—Full Suspension keeps travel speed consistent. (Volvo Construction Equipment)

How OBW Pays Back on Day One (and Every Shift After) OBW + TPMS in Saudi Heat

What OBW does: It measures payload in real time and provides a green-zone target. The loader sees external indicator lights so the bucket count hits nominal in 2–3 passes—no guessing, no “one more scoop just in case.” Result: fewer overload spikes, less carry-back, stable cycle time, and predictable fuel/ton. (Volvo Construction Equipment)

Why it matters in KSA: On long, hot hauls, overloading creates heat and slams fuel; underloading trashes your tons/hour. OBW removes both errors. Volvo CE frames it simply: “peak productivity, reduced fuel consumption and less machine wear” when overloading/carry-back are eliminated. (Volvo Construction Equipment)

Operator-visible proof: Haul Assist is integrated across Volvo’s ecosystem; the 2019 launch note underlines payload accuracy to prevent under/overloading. It’s not a gimmick—properly calibrated OBW becomes the site’s metronome. (Volvo Group)

TPMS: Your Tyre (and Fuel) Insurance in Saudi Heat OBW + TPMS in Saudi Heat

What TPMS does: Shows tyre pressure and temperature live on the display; alerts escalate from under-pressure to high-temperature warnings so operators and service teams act before damage. (Volvo’s monitoring intervals and warning logic are documented across Volvo’s technical collateral.) (Volvo Construction Equipment)

Why it matters: Under-inflated tyres increase rolling resistance, which drives fuel burn up and raises tyre temperature—a vicious loop in hot climates. Technical studies consistently show the link between under-inflation → higher rolling resistance → worse fuel economy. In on-road tests, a 10% increase in rolling resistance can move fuel consumption by ~1–2% depending on cycle; the physics applies off-road too, with site variables. (Mineta Transportation Institute)

Result: Keep tyres in-range and you protect fuel, tonnage, and casing life—and you stop surprise blowouts in August.

The KSA $/ton Stack: Where OBW + TPMS Cut Waste OBW + TPMS in Saudi Heat

Fuel/ton — OBW avoids overload spikes; TPMS reduces under-inflation drag. (Rolling resistance ↑ → fuel ↑.) (Mineta Transportation Institute)
Cycle time — Consistent target loads mean predictable acceleration and dump behaviour; fewer “overweight slowdowns.” (Volvo Construction Equipment)
Tyre life — Keeping temperature/pressure inside the window defends tread and bead integrity. (Volvo Construction Equipment)
Brake/retarder wear — With right payloads and speeds, operators lean on retarder correctly; service brakes last longer.
Unplanned stops — TPMS catches heat events before failures cascade into downtime.

Set-Up That Actually Works in Saudi OBW + TPMS in Saudi Heat

A. Calibrate OBW properly

Perform a baseline calibration after commissioning and after any tyre change that meaningfully shifts rolling radius.
Verify external loader lights are synced (green/amber/red thresholds). (Volvo Construction Equipment)

B. Program TPMS thresholds for summer

Use manufacturer guidance for cold pressures to hit the correct hot window; check morning vs mid-day drift.
Turn on high-temp warnings that prompt speed/load adjustments or cooldown cycles. (Volvo Construction Equipment)

C. Tyres & TMPH

Pick tyres with TMPH/TKMH that match cycle length and ambient temps; rotate on schedule. (Your PM team tracks TPMS heat spikes to spot abuse.)

D. Operator coaching that sticks

Train to load in 2–3 passes guided by OBW lights.
Coach retarder/engine-brake use on long grades; brakes are for stopping, not speed control.
Show crews how small pressure loss → temperature spike → fuel drag (pull a TPMS trend plot). (Mineta Transportation Institute)

E. Road discipline

One grader pass per shift often pays for itself in average speed and tyre life (less scrubbing/impact).

F. Safety and standards

Wire these tasks into your SOP under ISO 20474-1 (commissioning, operation, maintenance safety guidance). It’s the global reference for earth-moving machinery safety measures. (ISO)

A45G vs A45G FS (Full Suspension): Does FS Change the Math? OBW + TPMS in Saudi Heat

Yes—often. A45G FS maintains the same payload, power, and body volume as A45G but adds full suspension, which steadies travel speed on rough/temporary roads, reduces spillage and operator fatigue, and can lower $/ton even with a higher purchase price. In long approach legs or newly graded corridors, FS wins more often than buyers expect; we quote A45G vs A45G FS on the same route so you can see the delta. (Volvo Construction Equipment)

FAQ — KSA Buyers Ask About OBW/TPMS OBW + TPMS in Saudi Heat

Q1. Does OBW really change fuel per ton?
Yes. Overloaded trucks accelerate slower, dump slower, and heat driveline/tyres; underloaded cycles waste trips. OBW removes both, which Volvo documents as reduced fuel consumption and less wear via correct payloading. (Volvo Construction Equipment)

Q2. How is TPMS connected to fuel and tyre life?
Under-inflation increases rolling resistance, which raises fuel use and tyre temperature. Multiple technical studies and databases quantify this effect; the physics holds in off-road duty as well. Real-time TPMS helps keep tyres in range. (Mineta Transportation Institute)

Q3. We work rough, temporary roads. Is A45G FS worth it?
Often, yes. A45G FS (Full Suspension) keeps travel speeds steadier and reduces spillage/fatigue—many fleets see lower $/ton despite a higher sticker. We’ll quote A45G vs A45G FS on the same route so you can compare. (Volvo Construction Equipment)

Q4. Any safety standards we should frame maintenance under?
Use ISO 20474-1 for earth-moving machinery safety across commissioning, operation and maintenance. We map our PM checklists to that backbone. (ISO)

Q5. Will VAT change my OBW/TPMS decision?
VAT (15% standard rate in KSA) applies to parts and services; OBW/TPMS is about reducing operating cost and downtime, so it lowers $/ton regardless. Confirm tax treatment on ZATCA’s VAT portal for your inputs. (ZATCA)
