Checking a loaded BYD Shark 6 rear tyre with a gauge, showing the full-load pressure increase

BYD Shark 6 Tyre Pressure and TPMS Chart: The Manual's Numbers

The BYD Shark 6's manual specifies 2.5 bar, 250 kPa or about 36 psi, on all four 265/65 R18 tyres unloaded, and here is the ute detail most owners miss: at full load the rears rise to 2.9 bar, 290 kPa or about 42 psi. The TPMS warns when any tyre falls below 75 percent of standard, roughly 188 kPa, and when any tyre exceeds 85°C for three straight minutes.

Shark 6 Pressures at a Glance

Measurement Detail
Tyre size (manual) 265/65 R18
Unloaded, all wheels 2.5 bar, 250 kPa, about 36 psi
Full load, rear wheels 2.9 bar, 290 kPa, about 42 psi
Low-pressure alert Below 75% of standard, about 188 kPa
High-temperature alarm Above 85°C for three consecutive minutes

The Pressure Chart, Every Unit

Measurement bar kPa psi
Front, unloaded 2.5 250 36
Rear, unloaded 2.5 250 36
Front, full load 2.5 250 36
Rear, full load 2.9 290 42

Set pressures cold, before the day's driving, since a warm tyre reads high and tricks you into under-inflating.

The Ute Rule: When "Full Load" Applies to You

This is the row that separates ute owners from hatchback habits. Load the tray toward the manual's 790 kg payload margin, fill all five seats with gear, or hang the manual's 250 kg of ball load off a trailer, and the weight lands over the rear axle, which is exactly why the manual lifts only the rears to 2.9 bar. The habit to build: pump the rears up for the loaded job, and bleed them back to 2.5 when the tray empties, because running loaded pressures unladen wears the centre of the tread and rattles the ride. Our pickup bed guide covers the loading half of that equation.

Why Pressure Matters More on This Ute

Three things make the Shark 6 stricter about air than the average car. Mass first: 2,710 kg empty and up to 3,500 kg at full allowance is serious weight for four contact patches, and low pressure under load is precisely how tyres overheat, which is the failure the 85°C alarm exists to catch. Efficiency second: a PHEV's cheap electric kilometres depend on rolling resistance, so soft tyres quietly tax both the battery range and the 7.9 L/100 km engine figure. Stability third: with a trailer pushing 250 kg down on the ball, correctly inflated rears are what keep the steering honest. Air is the cheapest handling, safety, and economy upgrade the ute will ever get.

What the TPMS Actually Watches

  • Low pressure: Any tyre below 75 percent of standard, roughly 188 kPa against the 250 kPa setting, lights the fault warning and turns that tyre's value yellow, a check-and-inflate prompt for slow leaks
  • High temperature: Any tyre above 85°C for three consecutive minutes triggers the heat alarm and a yellow temperature value, and the manual's advice is to stop and let it cool
  • System fault: A flashing-then-solid warning light with "No Signal" or "Please check TPMS" on the cluster points to the monitoring module or nearby electromagnetic interference, dealer territory if it persists

Reading it is two presses: the steering wheel button opens the driving information bar, and pressing again brings up the live tyre pressure display.

The Manual's Honest Caveat

The system reports periodically rather than continuously, so a sudden blowout can outrun the next transmission, and the manual says it plainly: if the ute feels wrong, stop immediately rather than waiting for the display to agree. TPMS is an auxiliary system, and the monthly gauge check before driving remains your primary defence, exactly as our Shark 6 tyre pressure guide walks through.

Care Rules Worth Knowing

  • Sensor work is dealer work: The manual warns that an incorrectly installed monitoring module affects the tyre's air-tightness, so leave module swaps to BYD technicians at fitting time
  • Warnings after tyre work: If the light misbehaves after a rotation or new rubber, our TPMS warning reset guide covers the fix path
  • Mind the spare: The Shark 6 carries one, the annual service checks its security, and a spare only helps at pressure, so gauge it with the others
  • Cold mornings lie: Pressure falls with temperature, so a winter warning at dawn often just wants air, not alarm
